# Fix
Use the same durable, reviewable workflow as feature work. Diagnose first, then
produce the spec amendment, fix plan, and task files before changing production
code. The user reviews those artifacts, switches the main session if desired,
and sends a later explicit implementation request. Native subagents still

## Phase 0: Evidence And Root Cause
## Phase 0: Evidence and root cause
When a bug originates from an issue tracker, read the canonical issue and every
image attachment before hypothesizing. Reproduce with existing tests, a
read-only trace, or a minimal throwaway repro. Do not add production code during
this phase.
When a bug comes from an issue tracker, read the canonical issue and each image
attachment. Reproduce the behavior with existing tests, a read-only trace, or a
minimal temporary reproduction.
State the root cause before planning:
State:
- what is actually wrong, not only the symptom;
- why it happens and under which conditions;
- the smallest reliable reproduction; and
- the intended regression-test level and path.
- The incorrect behavior and its conditions.
- The root cause.
- The smallest reliable reproduction.
- The intended regression-test level and path.
If the problem cannot be reproduced or the cause remains unclear, stop and ask
the user rather than guessing at a fix.
If the cause remains uncertain, stop and ask the user.
## Phase 1: Fix Specification
## Phase 1: Reconcile specifications
Before implementation, find the affected durable spec under
`docs/specs/<slug>/spec.md` and amend its behavior or GIVEN/WHEN/THEN scenario
to cover the regression. If no relevant spec exists, create a concise repair
spec at `docs/specs/<fix-slug>/spec.md` that states the broken behavior, desired
behavior, regression scenario, out-of-scope work, and any relevant contract or
persistence constraint.
Read `docs/specs/README.md`, the owning system index, and the relevant
requirement and system-design documents. Use the legacy catalog only when the
system has not migrated.
This spec is the reviewable expected behavior; it is not an incident report.
Classify the bug:
## Phase 2: Fix Plan And Task Files
1. **Implementation violates an active acceptance criterion.** Reference the
existing `AC-*` ID. Do not create or rewrite a requirement.
2. **The intended behavior is missing from requirements.** Add the smallest
requirement and acceptance criteria that define it.
3. **The intended product behavior changes.** Amend or supersede the affected
requirement. Record the compatibility effect.
4. **The technical design is wrong or incomplete.** Update the system design.
Keep observable behavior in requirements.
Create `docs/plans/<fix-slug>/plan.md` and sibling
`docs/plans/<fix-slug>/task-<NN>-<short-slug>.md` files before implementation.
Follow the `/plan` structure, with these fix-specific requirements:
Do not create a standalone repair specification. The requirement is the durable
behavioral source. The plan and work orders record this repair.
- Link the amended repair spec and state the confirmed root cause.
- Include the regression test that must fail before the code change and pass
afterward.
- Name exact files, dependencies, acceptance criteria, and targeted commands.
- Use dependency waves and mark `parallel-safe` only for disjoint tasks with no
shared schema, migration, generated contract, lockfile, or package config.
- Keep `parallelism: sequential` by default in each task; waves are a human
decision aid, not authorization to delegate.
Use `/record` when the correction establishes a durable boundary, ownership
rule, public contract, persistence rule, or security invariant with meaningful
alternatives.
## Phase 3: Design-Package Handoff
## Phase 2: Create the fix package
Before changing production or permanent test code, present:
Create `docs/plans/<fix-slug>/plan.md` and sibling work orders through `/plan`.
- root-cause summary and reproduction evidence;
- amended/new spec path;
- fix plan and task-file paths;
- task waves, parallel candidates, and exact validation commands; and
- risks and out-of-scope work.
The package must:
End the turn after this handoff. Do not call `ask_user_question_kandev` (or an
equivalent approval prompt) to ask the user to approve the package or switch
models. The user reviews the files, switches the main session if desired, and
sends a later explicit implementation request. The files may remain
`draft`/`pending`; do not wait for a separate approval marker. Do not infer
subagent authorization from the plan.
- Reference the affected `REQ-*` and `AC-*` IDs.
- Reference the applicable system design.
- State the confirmed root cause.
- Name the regression test that fails before the correction.
- Name exact files, dependencies, acceptance conditions, and commands.
- Use dependency waves only when they clarify implementation order.
## Phase 4: Implement With TDD After Handoff
Keep work orders sequential by default. A wave does not authorize delegation.
After the user explicitly asks to implement, execute the tasks sequentially by
default:
## Phase 3: Design-package handoff
1. Mark the task `in_progress`.
2. Write and run the regression test; confirm it fails for the expected reason.
3. Implement the minimal fix.
4. Run the task's exact targeted unit, integration, or E2E command.
5. Mark the task `done` and update `plan.md` status in the primary session.
Before you change production or permanent test code, report:
For persisted defaults or coupled settings, audit every write/reset path for
explicit empty or null values. Add the smallest invalid-pair regression,
including fixture coverage, and verify normalized read-back plus existing
validation.
- Root cause and reproduction evidence.
- Requirement IDs and system-design paths.
- Plan and work-order paths.
- Dependency order and exact commands.
- Risks and exclusions.
When the user explicitly authorizes subagents, follow
`/planner-orchestration`: native delegation only, current user-selected model,
`fork_turns: "none"`, compact task-file handoffs, no recursive spawning, and
runtime usage-metadata confirmation. Only launch tasks marked parallel-safe.
Then end the turn. Do not ask the user to approve the package or switch models.
Wait for a later explicit implementation request.
## Phase 5: PR Review
## Phase 4: Implement with TDD
After all task checks pass, commit, push, and open the PR. Do not run
automatic local simplify, QA, code/security review, or broad verification. The
two configured PR AI reviewers are the semantic-review gate. Use `/pr-fixup`
only for CI failures or actionable reviewer findings, rerunning only the
affected task check after remediation.
After the explicit request:
## Stop Conditions
1. Change the work order to `in_progress`.
2. Write and run the regression test.
3. Make sure that the test fails for the expected reason.
4. Implement the minimum correction.
5. Run the work order's exact commands.
6. Change the work order to `done` and synchronize `plan.md`.
Stop and ask the user when the root cause is uncertain, the repair changes an
architecture/public-contract/persistence/security boundary, the spec and code
disagree, or the same targeted check fails three times.
For persisted defaults or coupled settings, inspect every write and reset path.
Cover explicit empty and null values when they affect the contract.
## Final Report
If the user authorizes subagents, obey `/planner-orchestration`. Use native
delegation, compact work-order context, no recursive delegation, and no
full-history fork.
Report the root cause, spec/plan/task paths, design-package handoff,
subagents explicitly authorized (if any), changed files, tests run, and current
PR-review status.
## Phase 5: PR review
After all work-order checks pass, commit, push, and open the PR. Do not add an
automatic local simplify, QA, broad review, security review, or verification
pass.
Use `/pr-fixup` only for a CI error or an actionable reviewer finding. Run the
affected work-order check after a correction.
## Stop conditions
Stop when the root cause is uncertain, specifications and code disagree, the
repair needs a new material design, or the same targeted check fails three
times.
## Final report
Report the root cause, requirement IDs, system-design path, plan and work-order
paths, changed files, commands, results, authorized subagents, and PR status.

# Create Implementation Plan
# Create an Implementation Plan
This is a primary-session artifact skill. The user-started conversation creates
the plan and task files, then returns control with a handoff. The user reviews
the files, switches that same conversation to an implementation model if
desired, and sends the explicit request to execute them.
Translate requirements and system designs into a delivery plan under
`docs/plans/<initiative>/`. The plan and its work-order files are implementation
records. They are not product specifications.
Translate a feature spec into a concrete, phased implementation plan saved under
`docs/plans/<feature>/`. Plans and task files are committed implementation
records for the current buildout; specs remain the durable requirements under
`docs/specs/`.
Read `docs/specs/guide/plans-and-work-orders.md` and
`docs/specs/guide/traceability-and-lifecycle.md` before you write the plan.
## Input
## Inputs
- The feature spec (`docs/specs/<slug>/spec.md`) — read it first
- The codebase — explore relevant areas before designing
Read these sources in full:
## Output
- The applicable requirement documents and `REQ-*` or `AC-*` IDs.
- The applicable system-design documents.
- Related ADRs.
- The relevant source, tests, and one similar implementation.
- `docs/plans/<slug>/plan.md` — a structured plan that links back to the spec
and references every task file
- `docs/plans/<slug>/task-<NN>-<short-slug>.md` — one independently executable
implementation task per file
Use the legacy feature specification during migration only when no replacement
requirement or design exists.
---
## Outputs
## Steps
Create:
### 1. Read the spec
```text
docs/plans/<initiative>/plan.md
docs/plans/<initiative>/task-<NN>-<short-slug>.md
```
Read `docs/specs/<slug>/spec.md` in full. Identify:
- The observable behaviors (What section)
- The scenarios — each is a potential test case
- Any out-of-scope items (don't plan for these)
`plan.md` is the work-package manifest. Each `task-*.md` file is one work order.
### 2. Explore the codebase
## Workflow
Search in parallel for all integration points the spec touches:
- Relevant models, repos, services, handlers
- Similar existing features to reuse as patterns
- Frontend state slices, hooks, and components in the area
- Existing tests in the area (to understand the testing patterns)
### 1. Map the change
Use `docs/decisions/INDEX.md` to check for relevant architectural decisions.
Identify:
Map dependencies before writing tasks. Implementation order follows the dependency chain: persistence/contracts first, service behavior next, API/client wiring after that, then UI and E2E. Prefer vertical slices that leave the product working over broad horizontal layers that cannot be verified until the end.
- The required outcomes and acceptance criteria.
- The design boundaries that implementation must preserve.
- Existing models, repositories, services, handlers, clients, stores, and UI.
- Existing tests and end-to-end patterns.
- The dependency order for implementation.
### 3. Ask before designing (if needed)
Check `docs/decisions/INDEX.md` for relevant decisions. Stop when the
requirements, system design, ADRs, and code disagree on a material boundary.
If the spec leaves implementation choices open, ask — one question at a time. Do not assume. Examples of things to ask:
- Which table/model owns new data?
- Is a new API endpoint needed or does an existing one extend?
- Should this be behind a feature flag?
### 2. Write `plan.md`
Stop asking when you have enough to write the plan.
### 4. Write plan.md
Save to `docs/plans/<slug>/plan.md`. Use this structure:

### <Component / Page>

### API client
What new calls are needed and where they go.
### State
Store slice / hook changes.
---
Name exact files, symbols, schema changes, contracts, and integration points.
Organize this section by implementation boundary or vertical slice.
## Tests
Every plan MUST include this section. For each testable behavior in the spec,
list the exact pre-PR validation:
- **What:** the behavior under test (maps to a spec scenario)
- **File:** where the test goes (`*_test.go` or `*.test.ts`)
- **How:** table-driven unit test / integration test with real DB / mock service
Map every relevant acceptance criterion to its unit or integration evidence.
Name the exact test file and method.
At minimum, include:
- One unit test per new function with non-trivial logic
- One integration test that exercises the full path (handler → service → repo)
- One test per edge case called out in the spec scenarios
## E2E tests
Do not add a generic local QA, review, security, simplify, or full-verification
step to the plan. The listed task checks are the pre-PR evidence; the two PR AI
reviewers perform semantic review after the PR opens.
Include this section when the change has user-visible behavior. Map each flow
to the applicable `AC-*` IDs and name the Playwright file and project.

## Open questions
## Implementation Waves And Parallel Candidates
Group task files by dependency order. Use waves to expose possible parallelism,
but label a task as parallel-safe only when its files are disjoint and it does
not touch shared schemas, migrations, generated contracts, lockfiles, or
package-wide configuration. E2E follows the backend and frontend changes it
covers.
The default is sequential execution in the primary conversation. Waves do not
authorize subagents: only the user may explicitly ask to use them after
selecting the implementation model.
```
Wave 1 (parallel candidates — user authorization required):
- [ ] [task-01-backend-contracts](task-01-backend-contracts.md)
- [ ] [task-02-backend-repository](task-02-backend-repository.md)
Wave 2:
- [ ] [task-03-frontend-ui](task-03-frontend-ui.md)
Wave 3:
- [ ] [task-04-e2e](task-04-e2e.md)
Delete this section when it is empty.
```
For small features (≤3 tasks total), waves are optional — list sequentially.
Do not place complete work-order bodies in `plan.md`.
The plan links to task files; it does not contain full task bodies. Update the
checkbox/status link when a task is completed.
### 3. Write work orders

## Open Questions

```
### 5. Write task files
Create one task file beside `plan.md` per task, named
`docs/plans/<slug>/task-<NN>-<short-slug>.md`. Use this structure:
```markdown
---
id: "01-backend-contracts"
title: "Backend contracts"
id: "01-<slug>"
title: "<Title>"

- AC-<SYSTEM>-<CAPABILITY>-001.1
system_design:
- ../../specs/<system>/system-design/<capability>.md
---
# Task 01: Backend contracts
# Task 01: <Title>
Each task should be small enough for one focused implementation pass:
- **Acceptance:** 1-3 concrete conditions.
- **Verification:** exact command(s), e.g. `cd apps/backend && go test -run TestName ./internal/path/...` or `cd apps && pnpm --filter @kandev/web test -- path/to/file.test.ts`. Frontend/E2E tasks must include the fresh-worktree bootstrap (`cd apps && pnpm install --frozen-lockfile`) when dependencies may be absent; direct web typechecking uses `cd apps/web && pnpm run typecheck`, while other workspace package commands use the documented `pnpm --filter` form. Backend commands should use the applicable repository `make` target when one exists. If several commands are required, write them as one sequentially runnable block rooted at a single directory (for example, `cd apps && ... && ...`) or make each `cd` explicit; do not rely on the caller's working directory surviving between commands.
- **Files likely touched:** specific paths, not broad directories.
- **Dependencies:** task numbers that must land first, or `None`.
- **Parallelism:** `sequential` by default; set `parallel-safe` only with named
disjoint files and no shared-state blocker.
- **Inputs:** relevant spec sections, plan sections, patterns, and dependencies.
- **Output contract:** summary, files changed, tests run, blockers, risks, and
task/plan status update in the same conversation.
## Summary
## Results
Pending. Before marking the task done, replace this with every exact command
actually run and its outcome/count, generated artifact paths, and cleanup or
teardown evidence (including temporary capture-spec removal and
`git diff --check` when used). Record security/trust and external side-effect
boundaries when applicable, or explicitly state `None`.
State the implementation outcome in two or three sentences.
Break a task down further if it touches unrelated subsystems, needs more than one focused session, or the title contains "and".
## In scope
When an implementation agent starts the task, it must change `status` to
`in_progress`. Before it finishes, reconcile **Files likely touched** with the
actual diff, including modified existing tests used as E2E evidence. It may then
change `status` to `done`, update its `## Results`, and synchronize the
corresponding checkbox/status and `## Verification Results` in `plan.md`.
- List the responsibilities that this work order owns.
## Out of scope
- List adjacent work that this work order does not own.
## Acceptance
- Give one to three concrete implementation conditions.
## Verification
```bash
<exact targeted command>
```
### 6. End the design turn
## Files likely touched
After `plan.md` and every task file are written and validated, report their
paths, dependency order, exact checks, and open risks as a compact handoff,
then end the turn. Do not call `ask_user_question_kandev` (or an equivalent
approval prompt) to ask the user to approve the plan or switch models. The user
reviews the artifacts and controls the next implementation request and model
choice.
- `path/to/file`
### Style rules
## Dependencies
- **Be specific.** Name exact file paths, function signatures, SQL column names. The implementing agent should not need to re-explore the codebase.
- **No speculation.** Only plan what the spec requires. Do not add "nice to have" items.
- **Tests are not optional.** Every plan must have a Tests section. E2E is required whenever there are UI changes.
- **Frontend is not optional.** If the spec has any user-visible behavior, the plan must have a Frontend section.
- **Keep it proportional.** A small spec gets a 1-page plan. A large spec may need 3-4 pages. Do not pad.
- **Keep task bodies out of the plan.** Put implementation details in individual
task files and link to them from `plan.md`.
Name prior work orders or write `None`.
## Risks
- Name concrete implementation or compatibility risks, or write `None`.
## Parallelism
`sequential`
## Inputs
- Requirement and system-design sections.
- Existing code and test patterns.
## Results
Pending.
````
Each work order must fit one focused implementation pass. Split work that has
unrelated outcomes, independent verification, or a title that contains “and.”
Use `parallel-safe` only when files are disjoint and the tasks share no schema,
migration, generated contract, lockfile, or package configuration. A wave does
not authorize subagents.
### 4. Define verification
Every work order needs exact commands. Use repository `make` targets when they
exist. Frontend work in a fresh worktree includes the workspace dependency
installation before the first package command.
User-facing behavior needs end-to-end evidence somewhere in the work package.
A low-level work order does not need an artificial browser test.
Do not add generic QA, review, simplify, security, or full-verification tasks.
Task checks provide pre-PR evidence. Configured PR reviewers provide semantic
review after the PR opens.
### 5. End the design turn
Report the requirement IDs, system designs, plan, work orders, dependency
order, exact checks, and open risks. Then end the turn.
Do not ask for plan approval or a model switch. The user reviews the artifacts
and sends a later explicit implementation request.

# Record Knowledge
Record architectural decisions for future reference, and keep related feature specs in sync.
Record significant decisions for future work. Reconcile the affected
requirements and system designs after the decision.
## Record a decision
When a significant architectural or design choice is made, create an ADR:
Create an ADR when all statements are true:
1. Choose a decentralized ID in the form `YYYY-MM-DD-short-title`. The short title must be
specific enough to remain unique among decisions created on the same date.
2. Confirm that `docs/decisions/<id>.md` does not already exist.
3. Create `docs/decisions/<id>.md` using the template below.
4. Update `docs/decisions/INDEX.md` with the new entry.
5. **Reconcile specs** — see "Update or create a spec" below.
- The choice creates a durable constraint, boundary, contract, ownership rule,
operational invariant, or repository-wide convention.
- Meaningful alternatives have different trade-offs.
- Future work must follow or supersede the choice.
- A requirement, system design, test, or work order does not preserve enough
rationale.
Existing numeric ADR IDs remain valid and must not be renamed. References use the complete stable
ID, for example `ADR-2026-07-16-project-shell-output`.
Do not create an ADR for a simple feature, local refactor, routine dependency
change, plan sequence, or temporary migration step.
### ADR template
## ADR procedure
1. Choose an ID in the form `YYYY-MM-DD-short-title`.
2. Make sure that `docs/decisions/<id>.md` does not exist.
3. Create the ADR with the template below.
4. Add it to `docs/decisions/INDEX.md`.
5. Reconcile affected specifications.
Existing numeric ADR IDs remain valid. Do not rename them.
```markdown
# ADR-YYYY-MM-DD-short-title: Short Title
# ADR-YYYY-MM-DD-short-title: Short title
**Status:** accepted | superseded by <adr-id> | deprecated
**Date:** YYYY-MM-DD
**Area:** backend | frontend | infra | protocol | workflow
## Context
What situation prompted this decision. 2-5 sentences.
Explain the situation and the need for a decision.
## Decision
What was decided. Reference file paths, packages, interfaces.
State the selected rule, boundary, or contract.
## Consequences
Trade-offs. What becomes easier or harder.
State benefits, costs, and follow-up constraints.
## Alternatives Considered
What else was considered and why it was rejected.
State each meaningful alternative and why it was not selected.
```
### What warrants an ADR
## Reconcile specifications
Create an ADR only when all of these are true:
Read `docs/specs/README.md`, the owning system index, and the relevant files in
`docs/specs/guide/`.
- The choice establishes a durable constraint, boundary, contract, ownership rule, operational
invariant, or repo-wide convention.
- There were meaningful alternatives with materially different trade-offs.
- Future work will need to follow or deliberately supersede the choice.
- A spec, plan, code comment, or regression test alone would not preserve enough of the reasoning.
Apply these rules:
Typical examples include selecting a system-wide communication model, defining ownership across
subsystems, changing a public API or persisted-data contract, and adopting a cross-cutting security
or reliability invariant.
- If the decision changes observable behavior, update the owning requirement
and its `REQ-*` or `AC-*` criteria.
- If the decision changes technical boundaries or contracts, update the owning
system design.
- If both change, update both artifacts and preserve their references.
- If the decision is internal and does not change a documented design, the ADR
is sufficient.
- If no product system applies, state that fact in the ADR.
### What does NOT need an ADR
Do not copy the ADR into requirements or system design. Link the ADR from the
affected design. Requirements contain observable outcomes, not decision
rationale.
- Simple features whose behavior belongs in a product spec
- Local implementation tactics and refactors within an existing pattern
- Routine dependency additions or upgrades
- Bug fixes unless they establish a new rule that future implementations must follow
- Plan sequencing, task breakdown, and temporary migration mechanics
- Anything obvious, uncontested, or easily reversible without cross-system consequences
During legacy migration, use `docs/specs/INDEX.md` to locate existing sources.
Do not create a new generic `spec.md` file.
## Update or create a spec
## Validation
ADRs capture *why* a decision was made. Specs capture *what* a feature does and why it exists. After recording an ADR, reconcile the affected spec — specs are the canonical product record kept in git, so they must stay accurate.
Run:
1. Read `docs/specs/INDEX.md` and identify any spec whose scope the decision touches (e.g., a routing decision affects `office-provider-routing/spec.md`).
2. For each affected spec:
- **If the decision changes observable behavior, scope, or scenarios:** update `docs/specs/<slug>/spec.md` so the "What" and "Why" sections reflect the new direction. Add a `Decision: ADR-<id>` reference where relevant.
- **If the decision is purely internal (implementation choice with no spec-visible change):** no spec edit needed — the ADR alone is sufficient.
3. If the decision introduces a new product feature that has no spec yet, invoke `/spec` to create one rather than writing it ad-hoc here.
4. If no spec applies (pure infra/process decision, like this knowledge system itself), skip — note in the ADR that no spec is needed.
```bash
python3 scripts/lint-spec-files.py --all
git diff --check -- docs/decisions docs/specs
```
Do not duplicate ADR content inside the spec. Specs reference ADRs; they don't restate them.
Report the ADR, affected requirement IDs, affected system designs, and the
validation result.

authorizes them after selecting the implementation model.

## Prompt-Precedence Gate
## Prompt-precedence gate
Treat workflow-generated envelopes such as `[IMPROVE PHASE]`, "implement the
requested change", Red-Green-Refactor checklists, verification commands, and
commit instructions as execution guidance for Phase 5, not as permission to
skip Phases 1–4. Before editing production or permanent test files, verify one
of these conditions:
Before you edit production or permanent test files, make sure that one condition
is true:
1. A prior design turn produced the spec, plan, and current task file, and the
user now explicitly asks to implement them; or
2. The request references an existing reviewed spec, plan, and current task
file; or
3. The user explicitly says to skip spec/plan/task creation.
1. A prior design turn produced the requirements, system design, plan, and
current work order. The user now explicitly asks to implement them.
2. The request references existing reviewed specifications, a plan, and the
current work order.
3. The user explicitly says to skip specification, plan, and work-order
creation.
If neither is true, create or update the spec, plan, and task files, record any
existing partial implementation as continuation context, and stop at the
design-package handoff. Do not call `ask_user_question_kandev` or ask the user
to approve the package or switch models at that checkpoint. A phase label or
generic "implement" directive generated by a Kandev workflow is not an
explicit opt-out.
Workflow envelopes, phase labels, TDD lists, and generic implementation prompts
do not satisfy this gate.
When a user explicitly asks to proceed with feature planning, complete the whole
strong-model design package — spec, plan, and task files — before returning
control. Do not add an approval/model-switch question at the handoff. Pause
after a standalone spec only when the user asks to review that spec before
planning, or when a material open question blocks a safe plan.
If no condition is true, create or update the design package. Record any partial
implementation as continuation context. Stop at the design-package handoff.
## Phase 0: Track The Work
When the user asks for feature planning, complete the full design package before
you return control. Stop after requirements only when the user requests a
requirements review or a material question blocks safe design.
Keep a visible task list and mark each phase as it completes:
## Phase 0: Track the work
1. Clarify intent
2. Create or update the spec
3. Create the implementation plan
4. Decompose it into task files
5. End the design turn and wait for the user's explicit implementation request
6. Execute tasks with TDD and targeted checks (sequential by default)
7. Open PR, address CI/review findings, record, and summarize
Keep a visible task list:
## Phases 1–4: Design On The Strong Model
1. Clarify intent.
2. Create or update requirements.
3. Create or update the system design.
4. Create the plan and work orders.
5. End the design turn.
6. Execute work orders with TDD after an explicit implementation request.
7. Open the PR, address valid findings, record changes, and report.
Use `/interview-me` only when the request is underspecified. Create or update:
## Phases 1 to 4: Design
- `docs/specs/<slug>/spec.md` through `/spec` for the durable product behavior.
- `docs/plans/<slug>/plan.md` through `/plan` for the technical sequence.
- `docs/plans/<slug>/task-<NN>-<short-slug>.md` for each independently
actionable implementation step.
Use `/interview-me` only when the request needs clarification.
The spec must cover relevant scenarios, contracts, permissions, failures, and
persistence guarantees. The plan must name likely files, dependency order,
tests, E2E coverage where applicable, risks, and exact verification commands.
Create or update:
Task files are the handoff between model tiers. Each must contain:
- `docs/specs/<system>/requirements/<capability>.md` through `/spec`.
- `docs/specs/<system>/system-design/<capability>.md` through `/spec`.
- `docs/plans/<initiative>/plan.md` through `/plan`.
- `docs/plans/<initiative>/task-<NN>-<short-slug>.md` through `/plan`.
- frontmatter: `id`, `title`, `status: pending`, `wave`, `depends_on`, `plan`,
and `spec`;
- 1–3 concrete acceptance conditions;
- exact targeted verification command(s);
- specific likely files and relevant spec/plan inputs;
- dependencies and risks.
During migration, use a legacy specification only when no new requirement or
system design replaces it.
Task files must not name a worker role or model tier. They may be grouped into
dependency waves and label parallel-safe candidates, but those labels are a
human decision aid: the primary session executes sequentially unless the user
explicitly asks to use subagents.
Requirements define stable `REQ-*` and `AC-*` IDs. System designs map technical
behavior to those IDs. Plans define delivery order. Work orders define one
implementation result and its verification.
## Design-Package Handoff
Each work order must contain:
Before any implementation, report the spec path, plan path, task-file list,
planned test commands, and any open risks.
- Frontmatter with `id`, `title`, `status`, `wave`, `depends_on`, `plan`,
`requirements`, `acceptance_criteria`, and `system_design`.
- A summary, scope, and exclusions.
- One to three implementation acceptance conditions.
- Exact targeted verification commands.
- Specific likely files, dependencies, and risks.
After reporting the handoff, end the turn. Do not call
`ask_user_question_kandev` (or an equivalent approval prompt), and do not ask
the user to approve the artifacts or switch models. The user reviews the files,
switches the model if desired, and sends a later explicit implementation
request. The files may remain `draft`/`pending`; do not wait for a separate
approval marker.
Work orders do not name a worker role or model tier. Waves can identify
parallel-safe candidates. They do not authorize subagents.
## Design-package handoff
Before implementation, report:
- Requirement documents and IDs.
- System-design paths.
- The plan and work-order paths.
- Dependency order and exact verification commands.
- Open risks and exclusions.
Then end the turn. Do not ask the user to approve the package or switch models.
The user reviews the files and sends a later implementation request.
Recommended Codex route:
- GPT-5.6 Sol/high for clarification, codebase investigation, specs, plans, and
- GPT-5.6 Sol/high for intent, investigation, specifications, plans, and
high-risk design.
- GPT-5.6 Terra/medium for implementation, TDD, targeted tests, and integration.
- GPT-5.6 Luna/low only for short, mechanical, read-only status work.
- GPT-5.6 Terra/medium for implementation, TDD, and integration.

Begin implementation only after that explicit implementation request. Never
infer a successful model switch from a model's prose; the user's runtime model
choice is authoritative when model confirmation is required.

## Phase 5: Execute work orders
For each task, in dependency order:
For each work order, in dependency order:
1. Read the task, relevant spec and plan sections, and scoped `AGENTS.md`.
2. Change only that task's status to `in_progress`.
3. Implement with `/tdd`; use `/e2e` and `/mobile-parity` when applicable.
4. Run the task's exact targeted verification command.
5. Update its status to `done` and update the corresponding `plan.md` status.

3. Implement with `/tdd`. Use `/e2e` and `/mobile-parity` when applicable.
4. Run the exact targeted verification commands.
5. Change the work order to `done` and synchronize `plan.md`.
If the user explicitly asks to implement with subagents, launch only
parallel-safe tasks in the requested wave. Use native delegation with no
full-history context fork, give each child the task-file path plus its owned
files and exact check, and keep shared-plan status updates in the main session.
The children use the implementation model active in the user-selected main
session; confirm that through runtime usage metadata before accepting results.
If the user authorizes subagents, launch only parallel-safe work orders in the
requested wave. Use native delegation with no full-history fork. Give each
child the work-order path, owned files, dependencies, and exact command.
If work reveals a new architecture, public contract, migration/persistence
boundary, or high-impact security decision, stop and ask the user whether to
switch back to the strong model before proceeding. Use `/record` if the decision
is durable.
If work needs a new architecture, public contract, persistence boundary, or
high-impact security decision, stop and request a strong-model design pass. Use
`/record` for a durable decision.
## Phase 6: Open The PR And Use Its Review Gates
## Phase 6: Open the PR
After all tasks pass their exact targeted checks, commit through `/commit`,
push, and open the PR. Do not automatically run `/simplify`, `/qa`,
`/code-review`, security review, or broad `/verify` before opening it.
After all work-order checks pass, request explicit user authorization before
running `/commit`, `/push`, or `/pr`. Run only the operations the user authorizes.
Do not add automatic local simplify, QA, broad review, security review, or
`/verify` work.
The two configured PR AI reviewers are the semantic-review gate. Use
`/pr-fixup` only for a CI failure or actionable reviewer finding. A fix reruns
the task's relevant targeted check and updates its task/plan status; do not run
a broad local suite unless the user explicitly asks.

# Writing a Spec
# Specification Authoring
This is a planner-side artifact skill. The user-started primary planner may
write and revise specs; implementation workers only read the relevant sections.
Use this skill to create or update durable specifications. Requirements define
observable behavior. System designs define the technical path that satisfies
requirements.
A spec captures **what** a feature does and **why**, before deciding **how**.
The canonical rules are in `docs/specs/guide/`. Read these files before you
write an artifact:
If the user intent is still vague, run `/interview-me` first. A spec records confirmed intent; it should not be the place where the agent guesses what the user meant.
- Always read `structure-and-ownership.md`.
- Read `requirements.md` for requirement work.
- Read `system-design.md` for system-design work.
- Read `traceability-and-lifecycle.md` for IDs, statuses, references, or
migration work.
## Bar
Use the templates in `docs/specs/templates/`.
The bar a spec must clear: **a fresh agent given only this spec (no source code) should be able to either reimplement the feature OR test the system for conformance.**
## Artifact routing
That means every requirement must be unambiguous. Where the feature has persistent state, the data model is documented. Where it exposes a contract (HTTP/WS/Go interface), the contract is documented. Where it has a multi-step lifecycle, the state machine is documented. If reading the spec leaves an implementer guessing, the spec is incomplete.
Route the request before you write:
## Gate: is this actually a feature?
| Request | Artifact |
| --- | --- |
| Kandev-wide purpose, actors, principles, measures, or constraints | `docs/specs/product/` |
| Observable behavior for one owning system | `<system>/requirements/` |
| Technical contracts, models, boundaries, or control flow | `<system>/system-design/` |
| Durable choice with meaningful alternatives | `/record` and an ADR |
| Delivery sequence and implementation tasks | `/plan` |
| Incident or behavior-preserving refactor | No product requirement |
| Bug | `/fix`, which checks the existing requirement first |
Before doing anything else, check that the topic is feature-shaped. A spec is appropriate ONLY when **all** of these are true:
Do not create a generic `spec.md` file.
- It describes a **product-feature surface** — a capability a user (human or office agent) can invoke.
- The "What" section can be written as observable behaviors the feature must support, not as a problem statement or a fix.
- The artifact will be a **living document** that evolves with the feature, not a one-shot record of a decision or incident.
## Workflow
If any of these are false, STOP and route to the right artifact:
### 1. Locate the owning system
| Situation | Use this instead |
|---|---|
| Bug fix | `/fix` — diagnose first, then amend/create its concise behavioral repair spec, plan, and task files before implementation. |
| Incident postmortem | `/record decision` when it establishes a durable convention; otherwise retain the incident record. |
| Architecture or convention decision | `/record decision` — produces an ADR under `docs/decisions/`. No spec. |
| Refactor that preserves behavior | Commit + (optional) ADR. No spec. |
| Infra / tooling / build / CI change | Commit + (optional) ADR. No spec. |
| Cluster of related sub-features under one umbrella | One spec for the umbrella feature, not one per sub-feature. |
Read `docs/specs/README.md` and the likely system `README.md`. If the system has
not migrated, use `docs/specs/INDEX.md` to locate the legacy source.
A "spec" that opens with a "Problem statement" or a "Root cause" section is not a spec. Specs describe what the feature **does for users**, not what went wrong or what we decided.
Choose the system that owns the concepts and contract. Other systems reference
that source. They do not copy it.
## What a spec is (and isn't)
If no system owns the behavior, define the new system boundary before you write
requirements. A new system needs a `README.md` based on the system template.
A spec **is**:
- The user-visible behavior of one feature
- A testable definition that the team agrees on before writing code
- The source of truth for "is this feature done?"
- Self-contained enough that an implementer or conformance tester needs nothing else
### 2. Confirm intent
A spec **is not**:
- An architecture or design document for *how* it's built (only contracts, not internals)
- A task list
- A retrospective of work already done
- A record of a bug, incident, or postmortem (those are ADRs and regression tests)
Use `/interview-me` when a missing product choice changes behavior, ownership,
permissions, persistence, or a public contract. Do not hide an unresolved
choice in a draft.
Implementation plans are separate committed artifacts under
`docs/plans/<feature>/`. A spec may link to the active plan, but requirements
must remain useful even when the plan changes.
### 3. Write requirements
## Where it lives
Create or update:
```
docs/specs/<umbrella>/<feature-slug>.md # nested under an umbrella when applicable
docs/specs/<feature-slug>/spec.md # standalone feature folder
```text
docs/specs/<system>/requirements/<capability>.md
```
- Umbrellas group related features into one product surface (e.g. `office/`, `tasks/`, `integrations/`, `agents/`, `workspaces/`, `costs/`).
- Slug is kebab-case, descriptive: `agents.md`, `provider-routing.md`. Avoid sequential numbering.
- One file per feature surface. Sub-features that don't have their own observable contract live as sections inside the parent.
Each requirement document must contain:
## Template
- Valid frontmatter.
- One or more stable `REQ-*` IDs.
- At least one `AC-*` acceptance criterion for each requirement.
- Observable behavior and explicit exclusions.
Required sections: `Why`, `What`, `Scenarios`, `Out of scope`.
Use user stories only when they clarify a natural actor and outcome. Do not put
files, functions, database queries, or implementation sequences in a
requirement.
Optional sections: include only when the feature has the corresponding concern. A small UI feature may need none of them; a stateful subsystem will need most. A spec may include an `Implementation plan` link to `docs/plans/<feature>/plan.md`, but requirements must not depend on plan-only context.
### 4. Write system design
```markdown
---
status: draft # draft | approved | building | shipped | archived
created: YYYY-MM-DD
owner: <name>
---
Create or update this file when the change needs a technical design:
# <Feature Name>
## Why
1-3 sentences. The user problem and who feels it. No solution yet.
## What
- Bullet list of must-have behaviors, written as observable outcomes.
- Reserve SHALL/MUST for hard requirements.
## Data model <-- include when the feature has persistent state
Entities, fields (with types), relationships. Where data lives (table name or
store). Constraints (uniqueness, foreign keys, nullability). One paragraph or
short table per entity. Diagrams only when multi-entity relationships aren't
obvious from prose.
## API surface <-- include when the feature exposes a contract
HTTP routes / WS event types / Go interfaces / CLI commands, with request
and response shapes. Names, paths, methods, payloads — not implementation.
Where an existing contract is reused, link to it instead of repeating.
## State machine <-- include when the feature has a multi-step lifecycle
States, transitions, the trigger for each transition, and which actor causes
each. A short list is fine for ≤6 states; a mermaid diagram or table for more.
## Permissions <-- include when authorization matters
Who (role / agent / external caller) can read, write, or invoke each action.
Cross-link to the agent-roles spec if the rule is "role X can do Y".
## Failure modes <-- include when failures are observable to the user or affect data
What happens when each external dependency fails or invariant is violated.
Whether the action retries, fails closed, falls back, or surfaces an error.
This is where fail-closed/safe-deletion/retry conventions get encoded.
## Persistence guarantees <-- include when restart behavior matters
What survives a kandev restart, what doesn't, and why. Covers worktrees,
sessions, queued work, in-flight runs, and any caches the user can observe.
## Scenarios
- **GIVEN** <state>, **WHEN** <action>, **THEN** <observable outcome>
The Scenarios section IS the conformance test surface. Write each scenario
so an agent could turn it directly into a test case — observable preconditions,
single triggering action, single observable outcome. Cover the golden path
plus every edge case that changes the design or has different observable
behavior than the golden path.
## Out of scope
- What this feature deliberately is not doing.
## Open questions
- (Delete this section when empty.)
```text
docs/specs/<system>/system-design/<capability>.md
```
## How to write each section
The design must list the applicable `REQ-*` IDs in frontmatter. It can use an
explicit empty list for internal infrastructure with no independent product
requirement.
### Why
Frame the **user problem**, not the solution. "Users can't resume a stopped session, so they lose context across restarts" — not "add a session/resume endpoint". One to three sentences. If you can't state the problem in three sentences, the feature is too big and should be split.
Describe stable components, models, contracts, flow, failure behavior,
persistence, security, and observability when they apply. Link to global ADRs.
Do not copy requirement or ADR text.
### What
Bullet list of must-have behaviors, written as **observable outcomes**. Reserve `SHALL`/`MUST` for hard requirements that would break the feature if removed; everything else is plain prose. Avoid implementation verbs ("call the API", "store in SQLite") — those belong elsewhere.
### 5. Update the system index
Good: "Stopped sessions resume into the last active turn."
Bad: "Add a `/sessions/:id/resume` POST endpoint that restores the ACP session."
Add the new documents to the system `README.md`. State the system boundary and
link adjacent systems when ownership can be confused.
### Data model
Include this section when the feature has any persistent state — DB tables, files on disk, state in a cache the user can observe. Name the entity, list its fields with types, note constraints (PK, FK, unique, nullable). Where the data lives (which table, which store) is part of the contract because conformance tests need to reach it.
During migration, name the new source as authoritative. Replace the old source
with a link or archive it. Do not leave two editable sources of truth.
```
worktree
id string PK
session_id string FK -> task_sessions.id (cascade delete)
worktree_path string abs path on disk, "" allowed only while creating
status enum active | merged | deleted
created_at timestamp
deleted_at timestamp nullable
### 6. Validate
Run:
```bash
python3 scripts/lint-spec-files.test.py
python3 scripts/lint-spec-files.py --all
git diff --check -- docs/specs docs/decisions
```
### API surface
List the contracts an external caller or another module relies on. HTTP routes (method, path, body, response codes), WS event types (name, payload), Go interfaces with signatures, CLI commands with flags. Don't describe internals — only what the boundary looks like. When an existing contract is reused, link to it.
If a file reaches its size limit, split it by capability, lifecycle, or contract
boundary. Do not add a size exception for a new document.
### State machine
For features with a multi-step lifecycle (task states, session states, run states, worktree states), enumerate the states, the transitions between them, the trigger for each transition, and which actor causes each. Capture which transitions require approval or block on external signals.
## Design-package behavior
### Permissions
When the feature has any authorization, document who can do what. "Workspace admins can delete projects; project members can create tasks; runner agents cannot create new agents." Cross-link to `agents/` or `workspaces/` specs when the rule is a role-derived rule.
When this skill runs inside `/spec-driven-development` or `/fix`, continue to
the system design, plan, and work orders. Stop after requirements only when the
user explicitly requests a requirements review or a material question blocks
safe design.
### Failure modes
Document the observable failure behavior for every external dependency the feature touches (DB, network, filesystem, external API) and every invariant it relies on. State whether the action retries, fails closed, falls back to a degraded path, or surfaces an error to the user. This is where conventions like "GC fails closed" or "approval requests retry on transient errors" become contract.
### Persistence guarantees
What survives a kandev process restart? Worktrees on disk, queued runs, in-flight ACP sessions, dashboard subscriptions. State explicitly what does NOT survive so implementers don't accidentally make it durable. Include any TTLs, retention policies, or cleanup grace periods.
### Scenarios
GIVEN/WHEN/THEN, observable from outside the system (UI state, API response, log line, DB row). Each scenario maps to one conformance test. Cover the golden path AND each edge case that changes the design.
```markdown
- **GIVEN** a stopped session with a pending tool call, **WHEN** the user clicks Resume, **THEN** the agent re-runs the tool call and continues the turn.
- **GIVEN** a worktree directory absent from `task_session_worktrees` and older than 24h, **WHEN** the office GC sweeps, **THEN** the directory is deleted and a log line `removing orphaned worktree directory` is emitted.
- **GIVEN** the worktree inventory query returns an error, **WHEN** the office GC sweeps, **THEN** no directories are deleted and a warning is logged.
```
### Out of scope
List explicit non-goals. Highest-value section for killing feature creep. Leave it in even when short — "no Windows support in this iteration" is a useful line.
### Open questions
Park unresolved decisions here while drafting. Each one blocks the spec from being approved. Delete the section once empty.
### Success criteria
When the request is vague ("faster", "better", "robust"), reframe it into measurable or observable success criteria before approving the spec.
Good:
- "The dashboard first content appears within 2.5s on the seeded E2E dataset."
- "A failed Jira auth refresh surfaces a settings banner and does not delete existing links."
Bad:
- "The dashboard should feel fast."
- "The integration should be robust."
## Right-sizing
The spec should be proportional to the feature. A small UI feature gets a 30-line spec with only Why/What/Scenarios/Out of scope. A stateful subsystem with persistence and a contract surface needs Data model + API surface + State machine + Failure modes + Persistence guarantees — and that's fine, because each of those is required to implement or test the feature correctly.
Signs a spec is the wrong size:
- **Too thin:** an implementer can't write the code without asking questions a conformance test would also need answered. Add the missing contract section.
- **Too thick:** content is restating what's in the code or the ADR. Cross-link instead of duplicating.
- **Too broad:** one spec covers multiple features that have different actors, contracts, or lifecycles. Split.
A padded spec is worse than a short one — it hides the requirements behind ceremony. But an under-specified spec fails the bar at the top of this file.
## Style notes
- **Symbols in code font.** File paths, packages, types, table names: `internal/agent/lifecycle`, `TaskSession`, `task_session_worktrees`.
- **Cross-link, don't duplicate.** Reference ADRs (`../../decisions/<adr-id>.md`) and other specs rather than restating their content.
- **Specs rarely need diagrams.** A user-flow mermaid is acceptable when it clarifies a multi-step interaction. Architectural diagrams do not belong here — those go in ADRs.
- **Present tense, active voice.** "The agent resumes the turn" — not "the turn will be resumed by the agent".
- **Concrete over abstract.** "Wakeups fire at most once per 60s per agent" is testable; "wakeups are rate-limited appropriately" is not.
- **Assumptions visible.** If you infer behavior from current code, name the assumption and keep it in Open questions until confirmed.
- **Review boundary.** When `/spec` is a standalone request, finish the spec
and return control without calling `ask_user_question_kandev` (or an
equivalent prompt) solely to request approval. When `/spec` is part of
`/spec-driven-development` or `/fix` planning, continue through the plan and
task files before the design-package handoff. A material open question that
prevents a safe plan is still a valid reason to ask for clarification.
For a standalone specification request, report the changed paths, requirement
IDs, design references, validation results, and open questions. Then return
control to the user.

### Knowledge
- **Public docs:** Website-ready user documentation lives in `docs/public/**`. Use `/docs-maintainer` when a change affects CLI commands, config keys, install/deploy flows, workflows, executors, public APIs, screenshots, or user-facing terminology.
- **Specs:** Feature specs live in `docs/specs/<slug>/spec.md` — the durable "what & why" of a feature, written before coding. Use `/spec` to write or update a spec. See `docs/specs/INDEX.md`.
- **Specifications:** Durable product context, requirements, and system designs
live under `docs/specs/**`. New work uses
`docs/specs/<system>/requirements/` and
`docs/specs/<system>/system-design/`. Read `docs/specs/README.md` and the
relevant file in `docs/specs/guide/`. Use `docs/specs/INDEX.md` only to find
unmigrated legacy specifications. Run `python3 scripts/lint-spec-files.py
--all` after specification changes.
- **Decisions:** Architecture decisions are recorded in `docs/decisions/`. Read `docs/decisions/INDEX.md` for an overview. When making significant architectural choices, create a new ADR via `/record decision`.
- **Plans:** Implementation plans are generated from specs via `/plan` and committed under `docs/plans/<slug>/plan.md`, with individual sibling task files named `docs/plans/<slug>/task-<NN>-<short-slug>.md`. Specs are the living requirements; plans and task files are implementation records for the current buildout.

manifest. Its sibling `task-<NN>-<short-slug>.md` files are work orders.

# ADR-2026-08-22-system-oriented-specifications: Organize Specifications by System
**Status:** accepted
**Date:** 2026-08-22
**Area:** workflow, infra
## Context
Kandev stores product requirements, technical contracts, and implementation
details in `docs/specs`. Many files now contain all three types of information.
This mixture makes the files difficult to find, maintain, and load into an
agent context.
The repository also uses two directory patterns. Some specifications use a
product group such as `tasks/` or `office/`. Other specifications use one
directory for each feature. The mixed structure weakens ownership and creates
large standalone documents.
## Decision
Keep `docs/specs` as the root for durable product and system specifications.
Organize new specifications by an owning system. Each system can contain these
directories:
- `requirements/` defines required and observable behavior.
- `system-design/` defines the technical design that satisfies requirements.
Use `docs/specs/product/` for Kandev-wide purpose, actors, principles, success
measures, constraints, and the product map. Keep plans and work orders in
`docs/plans`. Keep architecture decisions in `docs/decisions`.
Use stable `REQ-*` identifiers for requirements. Use stable `AC-*` identifiers
for acceptance criteria. System designs and work orders reference these
identifiers. Tests reference acceptance criteria when the mapping is useful.
Use `docs/specs/guide/` as the canonical authoring guide. Skills apply this
guide but do not duplicate its complete rules. A repository linter enforces
the mechanical rules, including file-size limits.
Do not move all legacy specifications in one mechanical change. A migration
must separate product intent from technical design. Each migrated system must
name one new source of truth before legacy content becomes a link or archive.
This decision amends the specification layout in ADR-0001. It does not change
the file-based and progressively loaded knowledge model.
No product specification needs an update. This decision changes the repository
authoring system and not Kandev product behavior.
## Consequences
Requirements and system designs stay close because they share an owning
system. Agents can load one system index and select only the necessary files.
The term `specification` becomes an umbrella term. New documents do not use a
generic `spec.md` filename. Authors must identify each document as a product
document, requirement, system design, ADR, plan, or work order.
The repository needs a controlled migration for existing specifications.
Legacy files remain valid until their owning system migrates. Oversized legacy
files cannot grow beyond their recorded size ceiling.
## Alternatives Considered
### Organize by artifact type
This option used separate top-level trees for requirements and technical
designs. It made artifact types easy to list, but it separated documents that
agents usually read together.
### Put each feature in its own directory
This option put `requirements.md` and `system-design.md` in a feature directory.
It gave strong local grouping, but it recreated the existing standalone-feature
sprawl.
### Use the term blueprint
This option followed an external software-factory model. The term did not match
Kandev terminology and implied a more rigid document than a living system
design.

## Conventions
## Legacy conventions
- **Spec layout.** Umbrella specs live as flat `.md` files under the umbrella directory (`docs/specs/office/agents.md`). Standalone specs use a folder (`docs/specs/improve-kandev/spec.md`).
- **Plans are not specs.** Implementation plans are committed under `docs/plans/<feature>/` with individual sibling task files named `task-<NN>-<short-slug>.md`. Specs are the durable requirements; plans and task files are implementation records for the current buildout.
- **Spec layout.** These two layouts remain valid only during migration.
Umbrella specs use flat files. Standalone specs use a `spec.md` file.
- **Plans are not specifications.** Implementation plans remain under
`docs/plans/<initiative>/`. Their task files are work orders.
- **Bug fixes are not specs.** Bugs produce a regression test plus an ADR if they encoded a new convention. See `/fix` skill.
- **Architecture decisions are not specs.** ADRs live under `docs/decisions/`. See `/record decision`.

# Kandev Specifications
This directory contains the durable product and system specifications for
Kandev. A specification describes product intent, required behavior, or the
technical design of a system.
New specifications use this structure:
```text
docs/specs/
├── product/
└── <system>/
├── README.md
├── glossary.md
├── requirements/
└── system-design/
```
Read the [specification guide](guide/README.md) before you create or change a
specification. Use the files in [templates](templates/) for new documents.
The existing [feature specification index](INDEX.md) remains the migration
catalog for legacy documents. A legacy document remains authoritative until
its system index names a replacement.
Plans and work orders are in [`docs/plans`](../plans/). Architecture decisions
are in [`docs/decisions`](../decisions/). Public user documentation is in
[`docs/public`](../public/).

# Specification Guide
This guide defines the Kandev specification system. The guide is the canonical
source for specification rules. Skills and templates reference these rules.
Read only the files that apply to the current task:
- [Structure and ownership](structure-and-ownership.md) defines systems,
directories, ownership, and document-size limits.
- [Requirements](requirements.md) defines requirements and acceptance criteria.
- [System design](system-design.md) defines technical design documents.
- [Traceability and lifecycle](traceability-and-lifecycle.md) defines IDs,
references, statuses, and migration rules.
- [Plans and work orders](plans-and-work-orders.md) defines delivery records.
The [system README](../templates/system-readme.md),
[requirement](../templates/requirement.md), and
[system-design](../templates/system-design.md) templates provide the required
document shapes.

# Plans and Work Orders
## Purpose
Plans and work orders are delivery records. They describe how a change moves
the current system toward its requirements and system design.
They are not living product specifications.
## Plan
`docs/plans/<initiative>/plan.md` is the work-package manifest. It contains the
delivery overview, dependency order, risks, verification strategy, and links to
each work order.
A plan references the applicable requirement documents and system designs. It
does not copy their content.
## Work order
Each `task-<NN>-<slug>.md` file is one work order. A work order contains:
- A short outcome summary.
- In-scope responsibilities.
- Explicit exclusions.
- Applicable `REQ-*` and `AC-*` identifiers.
- Applicable system-design paths.
- One to three implementation acceptance conditions.
- Exact verification commands.
- Likely files and dependencies.
- Results after implementation.
Use a separate work order when work has an independent result or verification
boundary. Do not split work only by backend and frontend layers when a vertical
slice can remain functional.
## Verification
Every work order owns the verification that proves its implementation result.
Use unit, integration, or end-to-end tests at the appropriate boundary.
A user-facing requirement needs end-to-end evidence somewhere in the work
package. A low-level work order does not need an artificial browser test.
Reference acceptance-criterion IDs from tests when that reference improves
traceability.

# Requirements
## Purpose
Requirements define what an actor or consumer must observe. They explain the
intent and the behavior without prescribing the implementation.
An actor can be a user, operator, agent, plugin, integration, or another Kandev
system. Do not force a user story when no natural user story exists.
## Document structure
A requirement document contains:
- An overview of the capability and its value.
- Terms that are necessary to interpret the requirements.
- One or more requirements with stable IDs.
- Acceptance criteria for every requirement.
- Explicit exclusions.
Add permissions, failure behavior, persistence, compatibility, or performance
criteria when they affect observable behavior.
## Requirement IDs
Use this form:
```text
REQ-<SYSTEM>-<CAPABILITY>-<NNN>
```
Use uppercase letters, digits, and hyphens. Use a three-digit sequence. Do not
reuse an ID after removal.
One requirement describes one cohesive capability or outcome. The title is a
short noun phrase.
## Acceptance criteria
`AC` means acceptance criterion. The plural term is acceptance criteria.
Use this form:
```text
AC-<SYSTEM>-<CAPABILITY>-<NNN>.<N>
```
The part before the decimal point must match its requirement ID. Each criterion
defines one independently testable behavior.
Use this sentence form when it fits:
```text
When <condition>, the system shall <observable behavior>.
```
Use `shall` for required behavior, `should` for a recommendation, and `can` for
an allowed behavior. Avoid vague terms such as appropriate, fast, robust, or
user-friendly. Give an observable result or a measurable limit.
## User stories
A user story gives useful intent when the capability has a natural actor and
outcome. Use this form:
```text
As a <role>, I want <action>, so that <outcome>.
```
A user story does not replace acceptance criteria. Omit it when it creates an
artificial actor such as "the system."
## Content boundary
Requirements can name a public API, event, or persisted concept when that name
is part of the observable contract. Requirements do not define internal files,
functions, database queries, or implementation sequences.
Put technical models, control flow, storage choices, and component ownership in
the paired system design. Put design rationale and rejected alternatives in an
ADR.
## Splitting requirements
Split a document when its requirements have different actors, lifecycles, or
contracts. Keep requirements together when they are necessary to complete one
user or system outcome.
Use references instead of copied text when another system owns a requirement.

# Structure and Ownership
## Specification root
`docs/specs` is the root for durable Kandev specifications. The directory uses
systems as its primary organization.
```text
docs/specs/
├── product/
└── <system>/
├── README.md
├── glossary.md
├── requirements/
└── system-design/
```
A system owns a stable set of concepts, behavior, and technical boundaries.
Examples include the task system, agent runtime, plugin system, and GitHub
integration.
## System test
Create a system directory when at least two statements are true:
- The system owns a stable vocabulary or data model.
- Multiple consumers depend on its behavior or guarantees.
- The system has an independent lifecycle.
- A team can design and review its changes independently.
- Several features or other systems depend on it.
Do not create a system for one helper, component, page, or endpoint. Put that
design in the system that owns the behavior.
## System ownership
Each requirement has one owning system. Another system can reference the
requirement but must not copy it.
Each system has a `README.md`. This file defines the system boundary and links
to its requirements and system designs. Use `glossary.md` only when the system
has terms that need precise definitions.
The system index sets `migration: in_progress` while legacy files remain. Set
it to `complete` only after the index names the new authoritative documents and
all editable legacy sources become links or archives. The linter enforces the
strict system layout after migration is complete.
A system does not need both artifact directories. A low-level system can have
system designs without product requirements. Do not create empty placeholder
documents.
## Product specifications
`docs/specs/product` contains Kandev-wide context. It can contain these files:
- `overview.md` explains the product problem and boundary.
- `actors.md` defines people, agents, plugins, and external systems.
- `product-map.md` maps the systems and their relationships.
- `principles.md` defines durable product principles.
- `success-measures.md` defines measures that the team uses.
- `product-constraints.md` defines cross-system quality and compatibility
requirements.
Do not put feature requirements, API details, roadmaps, or work status in the
product directory.
## Cross-system design
The system that owns a contract also owns its design. Other system designs link
to that contract. Do not create a separate shared-design tree only because two
systems use the same capability.
Create a first-class system when shared behavior has independent ownership and
guarantees. Event delivery and persistence can become systems under this rule.
## File names
Use a short kebab-case capability name. Use the same file name for the paired
requirement and system design when practical.
```text
task-system/requirements/dependencies.md
task-system/system-design/dependencies.md
```
Do not create new files named `spec.md`. The file name must identify the
capability.
## Context limits
The specification linter reads the limits from `docs/specs/spec-lint.json`.
The default limits are:
- System index: 12 KiB.
- Product or guide document: 16 KiB.
- Requirement document: 20 KiB.
- System-design document: 32 KiB.
- Template: 8 KiB.
- Unmigrated legacy specification: 32 KiB.
Split a file before it reaches its limit. Split by capability, lifecycle, or
contract boundary. Do not split by arbitrary line ranges.
An oversized legacy file can have a frozen ceiling in the linter configuration.
The ceiling permits migration work but does not permit growth. Lower the ceiling
in the same change whenever the file shrinks. Remove the exception after the
file falls below the default limit.

# System Design
## Purpose
A system design explains how Kandev satisfies one or more requirements. It is a
living technical specification that maps to real runtime boundaries and code.
## Required content
Every system design identifies its owning system and its requirement IDs. Use
an empty `requirements` list only when the design defines internal technical
infrastructure with no independent product requirement.
A design contains the sections that its subject needs. Common sections include:
- Context and boundaries.
- Components and responsibilities.
- Data models and contracts.
- Control flow and state transitions.
- Failure and recovery behavior.
- Permissions and security boundaries.
- Persistence and migration behavior.
- Observability.
- Related ADRs.
Do not add empty sections.
## Code grounding
Reference real packages, types, endpoints, events, tables, and configuration
keys. Use Markdown links for repository documents. Use code formatting for code
symbols.
Describe stable boundaries and behavior. Do not copy complete source code or
list every helper function.
## Requirement mapping
Map each referenced requirement to the design section that satisfies it. A
short table is sufficient.
Do not copy requirement text into the design. Reference the stable `REQ-*` and
`AC-*` identifiers.
## Decisions
Use an ADR when a choice creates a durable boundary, contract, ownership rule,
or operational invariant with meaningful alternatives. Link the ADR from the
design.
Do not create locally numbered ADR sections inside a system design. The global
decision log is the source of truth for design rationale.
## Design changes
Update the design when implementation changes a documented boundary or
contract. Do not update it for a local refactor that preserves the design.
When code and design disagree, stop and identify the intended source of truth.
Do not silently rewrite the design to match accidental behavior.
@@ -0,0 +1,69 @@
# Traceability and Lifecycle
## Traceability chain
Kandev uses this traceability chain:
```text
REQ -> AC -> system design -> work order -> test
```
Requirements own product behavior. System designs own the technical path. Work
orders own implementation scope. Tests provide executable evidence.
## References
A system design lists its `REQ-*` references in frontmatter. A work order lists
the applicable `REQ-*` and `AC-*` identifiers and its system-design paths.
Use an `@covers AC-...` annotation in a test name or nearby comment when the
mapping is not clear from the test location. Do not add a second coverage ID
unless a tool requires one.
Do not copy requirement text into a system design or work order. If an isolated
execution environment needs the text, generate a snapshot and record the source
commit.
## Status values
System indexes use `draft`, `active`, or `retired`. Their `migration` field uses
`in_progress` or `complete`.
Requirement documents use:
- `draft`: The behavior is not yet accepted.
- `active`: The behavior is the current product contract.
- `deprecated`: The behavior remains documented during removal or transition.
System-design documents use:
- `draft`: The technical design is not yet accepted.
- `current`: The design describes the current intended system.
- `superseded`: Another design replaced this design.
Work orders use `pending`, `in_progress`, `blocked`, `done`, or `cancelled`.
Implementation state does not change a requirement document from `active` to
`shipped`. Delivery state belongs to plans, work orders, and coverage evidence.
## Stable identities
Requirement and acceptance-criterion IDs do not change when a file moves. Do
not reuse removed IDs. A replacement requirement references the requirement
that it supersedes.
## Migration
Migrate one system at a time. Use this sequence:
1. Create the system `README.md`, define its boundary, and set
`migration: in_progress`.
2. Inventory the legacy specifications that the system owns.
3. Extract observable behavior into requirement documents.
4. Extract technical contracts and design into system-design documents.
5. Add stable IDs and cross-references.
6. Name the new documents as authoritative in the system index.
7. Add a short link to the system `README.md`, or archive the legacy document
outside `docs/specs/<system>/`.
8. Set `migration: complete` and remove obsolete size exceptions.
Do not keep two editable sources of truth during migration.

# Product Specifications
This directory contains Kandev-wide product context. These documents apply to
several systems and help readers interpret system requirements.
Add a document only when the team has confirmed its content. Do not create
empty product documents from a template.
The expected subjects are:
- Product overview and boundary.
- Actors and their goals.
- Product map and system relationships.
- Durable product principles.
- Success measures that the team uses.
- Cross-system product constraints.
System-specific behavior belongs in the owning system under `requirements/`.
Technical implementation belongs in `system-design/`.
