## Writing a test
1. Read `helpers/api-client.ts` and `pages/` to discover available seed methods and page objects
2. Import fixtures from `../../fixtures/test-base` — provides `testPage`, `apiClient`, and `seedData` (pre-created workspace with default workflow)
2. Import fixtures from `../../fixtures/test-base` — provides `testPage`, `apiClient`, and `seedData` (pre-created workspace with default workflow). Pull `backend` from the fixture too when you need the backend URL — it's worker-scoped, dynamic, and `process.env.KANDEV_API_BASE_URL` is **not** set in the Playwright runner (only in the frontend SSR child process). Use `backend.baseUrl`.
3. Use `data-testid` attributes for selectors — add them to components as needed
4. Use page objects for common interactions; create new ones for new pages
5. For GitHub features, use `apiClient.mockGitHub*()` methods to seed mock data
### IDs and response shapes — common pitfalls
- **`apiClient.createTaskWithAgent(...)` returns `CreateTaskResponse`**, which is `Task & { session_id?: string; agent_execution_id?: string }`. Read `created.session_id` directly — don't call `listTaskSessions(taskId)` just to fetch the session that was auto-started by the same call.
- **The URL `/t/:id` contains the TASK ID**, not the session ID. Backend routes like `/port-proxy/:sessionId/:port/*path` expect the session ID. Don't extract IDs from `window.location.pathname` when you need a session ID — pull from the API response.
- **`page.request` shares cookies/storage with the page context**. Fine for the current no-auth local backend; if auth ever lands, this is where you'd plug it in.
- **Preview iframe tests:** the seed repo has no `dev_script` configured, so the preview panel renders a placeholder ("Configure a dev script…") and the URL input never appears — tests that try to drive it hang on the locator timeout. To use the preview iframe in a test, set one first: `await apiClient.updateRepository(seedData.repositoryId, { dev_script: "echo dev" })`. Then click the Preview dockview tab (`await session.clickTab("Preview")`) — the toolbar will mount and the URL input becomes targetable.

- **Do not mark task 4 completed until every previously-unresolved review thread is either resolved or has an explicit reason documented in a reply.** If you finish the pass and the `isResolved == false` set is still non-empty, you are not done.
**Important: issue comments vs review comments use different APIs:**
- **Review comments** (inline, from `gh api repos/:owner/:repo/pulls/<number>/comments`) — reply via `/pulls/<number>/comments/<comment_id>/replies`, react via `/pulls/comments/<comment_id>/reactions`
- **Issue comments** (conversation timeline, from `gh pr view --json comments` — e.g., CodeRabbit walkthrough) — reply by posting a new comment via `gh pr comment <number> --body "..."`, react via `/issues/comments/<comment_id>/reactions`
- **Review comments** (inline, from `gh api repos/:owner/:repo/pulls/<number>/comments`) — use `scripts/pr-resolve` (below).
- **Issue comments** (conversation timeline, from `gh pr view --json comments` — e.g., CodeRabbit walkthrough) — reply by posting a new comment via `gh pr comment <number> --body "..."`, react via `gh api repos/:owner/:repo/issues/comments/<comment_id>/reactions -f content="+1"`. There's no "resolve" concept for issue comments.
**For valid comments:**
1. Read the file at the referenced line
2. Implement the fix
3. React with thumbs up:
```bash
# For review comments:
gh api repos/:owner/:repo/pulls/comments/<comment_id>/reactions -f content="+1"
# For issue comments:
gh api repos/:owner/:repo/issues/comments/<comment_id>/reactions -f content="+1"
```
4. Resolve the review thread (see below for thread ID retrieval)
### Review comments: `scripts/pr-resolve`
Use the script for every review thread, not just batches — it collapses reply + resolve + +1 reaction into a single call so you don't re-derive the graphql mutation each session.
**For skipped comments** (already addressed, nitpick, wrong, or outdated):
1. Reply to the comment explaining why it was skipped:
```bash
# For review comments:
gh api repos/:owner/:repo/pulls/<number>/comments/<comment_id>/replies -f body="<explanation>"
# For issue comments:
gh pr comment <number> --body "<explanation>"
# Dump every unresolved thread, TAB-separated (tid, cid, author, path, body_first_120):
scripts/pr-resolve list <PR>
# Reply + resolve + +1 (same call whether you're agreeing or pushing back —
# the body text conveys which):
scripts/pr-resolve reply <PR> <CID> <TID> "Fixed — monotonic counter via useRef. See commit abc1234."
scripts/pr-resolve reply <PR> <CID> <TID> "Acknowledged; the strict source check was relaxed for E2E. Tracking as a follow-up."
```
Examples:
For valid comments: read the file, implement the fix, then call `pr-resolve reply` with a body that names the commit or the file:line of the fix.
For skipped comments (already addressed, nitpick, wrong, outdated): call `pr-resolve reply` with a body that explains why. Examples:
- "This is already handled by X on line Y."
- "This is a style preference not enforced by our linters — keeping as-is."
- "This refers to code that was changed in a later commit."
2. Resolve the review thread
- "Refers to code that was changed in a later commit."
For dozens of threads grouped by topic, declare a bash associative array mapping thread IDs → category, then a `reply_for` case that returns the right body per category. Avoids retyping the same explanation across duplicate threads from multiple bots:
**Resolving threads:** First fetch thread node IDs to map comment IDs to threads:
```bash
gh api graphql -f query='
query($owner: String!, $repo: String!, $number: Int!) {
repository(owner: $owner, name: $repo) {
pullRequest(number: $number) {
reviewThreads(first: 100) {

comments(first: 1) {
nodes { databaseId }
declare -A CAT=(
[PRRT_xxx1]=fixed_counter

)
declare -A CID=(
[PRRT_xxx1]=3253164429
[PRRT_xxx2]=3253168996
[PRRT_xxx3]=3253164669
)
reply_for() {
case "$1" in
fixed_counter) echo "Fixed — monotonic counter via useRef. See commit abc1234." ;;
skipped_source_guard) echo "Acknowledged; the strict source check was relaxed for E2E. Tracking as a follow-up." ;;
esac
}
}
}
}
}
}' -f owner=":owner" -f repo=":repo" -F number=<number>
```
Then resolve using the thread `id`:
```bash
gh api graphql -f query='mutation { resolveReviewThread(input: {threadId: "<thread_node_id>"}) { thread { isResolved } } }'
for TID in "${!CAT[@]}"; do
scripts/pr-resolve reply <PR> "${CID[$TID]}" "$TID" "$(reply_for "${CAT[$TID]}")"
done
```

- If new review comments appeared after the push → loop back to task 3.
- If the poller hit its cap (`recommendation:` mentions "timed out") → surface the remaining pending items to the user and stop.
**Force-push (rebase) can re-open previously resolved inline threads.** GitHub treats the new commit's diff as a fresh review surface, so threads you already replied-to-and-resolved may come back unresolved with their original bodies. Before re-fixing, fetch the comments and check the body — if the issue is already addressed in the new tip, reply "Already fixed in `<sha>`" and resolve again rather than re-implementing.
**Mergeable status lags after a force-push.** `gh pr view --json mergeable` can show `CONFLICTING` / `mergeStateStatus: DIRTY` for ~5-10s while GitHub recomputes against the new tip. Wait briefly before deciding there's a real conflict, and confirm with `git fetch origin main && git diff --name-only HEAD origin/main` locally.
**Polling that times out is often a "main moved" signal.** A 20-min E2E window is long enough for `main` to ship one or two PRs. Before the next iteration, run `git fetch origin main && git log HEAD..origin/main --oneline` — a non-empty result means a rebase is coming. Rebase, force-push, and re-poll once rather than chasing flaky test reruns.
Cap re-check loops at **3 iterations** to prevent runaway sessions. After 3, surface the remaining state to the user and stop.

### Key Concepts
**Orchestrator** coordinates task execution:
- Receives task start/stop/resume requests via WebSocket
- Delegates to lifecycle manager for agent operations
- Handles event-driven state transitions via workflow engine
- Located in `internal/orchestrator/`
**Workflow Engine** (`internal/workflow/engine/`) provides typed state-machine evaluation:
- `Engine.HandleTrigger()` evaluates step actions for triggers (on_enter, on_turn_start, on_turn_complete, on_exit)
- `TransitionStore` interface abstracts persistence (implemented by `orchestrator.workflowStore`)
- `CallbackRegistry` maps action kinds to callbacks (plan mode, auto-start, context reset)
- First-transition-wins: multiple transition actions in one trigger, first eligible wins
- `EvaluateOnly` mode: engine evaluates without persisting, caller orchestrates on_exit → DB → on_enter
- `RequiresApproval` on actions: transitions requiring review gating are skipped
- Idempotent by `OperationID`; session-scoped data bag via `MachineState.Data`
**Agent Runtime** (`internal/agent/runtime/`) is the single seam for launching, resuming, stopping, and observing agent executions. ADR 0004 introduced this in Phase 1 of task-model-unification. The public surface is `runtime.Runtime` (`runtime.go`); a thin facade (`facade.go`) delegates to a `Backend` (satisfied by `*lifecycle.Manager`).
**Convention:** only `internal/agent/runtime/` (and code that pre-dates Phase 1 migration) may import `runtime/lifecycle` or `runtime/agentctl` directly. New consumers — workflow engine actions, cron-driven trigger handlers, future task-tier callers — should depend on `runtime.Runtime`. Existing call sites are migrated through later phases of task-model-unification.
**Lifecycle Manager** (`internal/agent/runtime/lifecycle/`) manages agent instances under the runtime:
- `Manager` (`manager.go`, `manager_*.go`) - central coordinator for agent lifecycle
- `ExecutorBackend` interface (`executor_backend.go`) - abstracts execution environment (Docker, Standalone, Sprites, Remote Docker)
- `ExecutionStore` (`execution_store.go`) - thread-safe in-memory execution tracking
- `session.go` - ACP session initialization and resume
- `streams.go` - WebSocket stream connections to agentctl
- `process_runner.go` - agent process launch and management
- `profile_resolver.go` - resolves agent profiles/settings
**agentctl client** (`internal/agent/runtime/agentctl/`) is the HTTP/WS client used by the lifecycle manager to talk to a running agentctl instance. It is a runtime-tier package and should not be imported outside `internal/agent/runtime/`.
**agentctl** is an HTTP server that:
- Runs inside Docker containers or as standalone process
- Manages agent subprocess via stdin/stdout (ACP protocol)
- Exposes workspace operations (shell, git, files)
- Supports multiple concurrent instances on different ports
**Executor Types** (database model):
- `local_pc` - Standalone process on host ✅
- `local_docker` - Docker container on host ✅
- `sprites` - Sprites cloud environment ✅
- `remote_docker`, `remote_vps`, `k8s` - Planned
### Execution Flow
```
Client (WS) → Orchestrator → Lifecycle Manager → ExecutorBackend (container/process) → agentctl
↓
Client (WS) ← Orchestrator ← Lifecycle Manager ←──── stream updates (WS) ──────── agent subprocess
```
1. Orchestrator receives `session.launch` via WS
2. Lifecycle Manager creates executor instance (container or process)
3. agentctl starts inside the instance, agent subprocess is configured and started
4. Agent events stream back via WS through the chain
**Session Resume:** `TaskSession.ACPSessionID` stored for resume; `ExecutorRunning` tracks active state; on restart `RecoverInstances()` reconnects.
**Provider Pattern:** Packages expose `Provide(cfg, log) (*impl, cleanup, error)` for DI. Returns implementation, cleanup function, and error. Cleanup called during graceful shutdown.
**Worktrees:** `internal/worktree/Manager` provides workspace isolation. Each session can have its own worktree (branch) to prevent conflicts between concurrent agents.
**Executor default scripts:** Default prepare scripts are in `internal/agent/runtime/lifecycle/default_scripts.go`; `internal/scriptengine/` handles placeholder resolution.

## agentctl Server
### API Groups
agentctl exposes these route groups (see `internal/agentctl/server/api/`):
- `/health`, `/info`, `/status` - Health and status
- `/instances/*` - Multi-instance management
- `/processes/*` - Agent subprocess management (start/stop)
- `/agent/configure`, `/agent/stream` - Agent configuration and event streaming
- `/git/*` - Git operations (status, commit, push, pull, rebase, stage, etc.)
- `/shell/*` - Shell session management
- `/workspace/*` - File operations, search, tree
- `/vscode/*` - VS Code integration proxy
### Adapter Model
Protocol adapters in `adapter/transport/` normalize different agent CLIs:
- `AgentAdapter` interface defines `Start()`, `Stop()`, `Prompt()`, `Cancel()`
- Transports: `acp` (Claude Code), `codex` (OpenAI Codex), `opencode`, `shared`, `streamjson`
- Top-level adapters: `CopilotAdapter` (GitHub Copilot SDK), `AmpAdapter` (Sourcegraph Amp)
- `process.Manager` owns subprocess, wires stdio to adapter
- Factory pattern in `adapter/factory.go` selects adapter by agent type
### ACP Protocol
JSON-RPC 2.0 over stdin/stdout between agentctl and agent process. Requests: `initialize`, `session/new`, `session/load`, `session/prompt`, `session/cancel`. Notifications: `session/update` with types `message_chunk`, `tool_call`, `tool_update`, `complete`, `error`, `permission_request`, `context_window`.
---
## Frontend Architecture
### UI Components
**Shadcn Components:** Import from `@kandev/ui` package:
```typescript
import { Badge } from '@kandev/ui/badge';
import { Button } from '@kandev/ui/button';
import { Dialog } from '@kandev/ui/dialog';
// etc...
```
**Do NOT** import from `@/components/ui/*` - always use `@kandev/ui` package.
### Data Flow Pattern (Critical)
```
SSR Fetch -> Hydrate Store -> Components Read Store -> Hooks Subscribe
```
**Never fetch data directly in components.**
### Store Structure (Domain Slices)
```

├── health-api, utility-api
```
**Key State Paths:**
- `messages.bySession[sessionId]`, `shell.outputs[sessionId]`, `gitStatus.bySessionId[sessionId]`
- `tasks.activeTaskId`, `tasks.activeSessionId`, `workspaces.activeId`
- `repositories.byWorkspace`, `repositoryBranches.byRepository`
**Hydration:** `lib/state/hydration/merge-strategies.ts` has `deepMerge()`, `mergeSessionMap()`, `mergeLoadingState()` to avoid overwriting live client state. Pass `activeSessionId` to protect active sessions.
**Hooks Pattern:** Hooks in `hooks/domains/` encapsulate WS subscription + store selection. WS client deduplicates subscriptions automatically.
### WS
**Format:** `{id, type, action, payload, timestamp}`.
- `apps/backend/AGENTS.md` — Go backend: package structure (incl. `internal/office/` and `internal/agent/runtime/`), key concepts (orchestrator, workflow engine, agent runtime, lifecycle manager), execution flow, provider pattern, backups, testing conventions, Go lint limits.
- `apps/backend/internal/agentctl/AGENTS.md` — agentctl HTTP server: route groups, adapter model, ACP protocol.
- `apps/backend/internal/agentctl/server/api/AGENTS.md` — reverse-proxy body rewriting (`Accept-Encoding`), iframe-blocking header stripping.
- `apps/backend/internal/integrations/AGENTS.md` — adding a new third-party integration (Jira/Linear pattern, both backend and frontend halves). The `/add-integration` skill mirrors this for scaffolding new integrations.
- `apps/web/AGENTS.md` — Next.js frontend: shadcn imports, SSR-hydrate-store data flow, store slice structure (incl. `office`), WS format, component conventions, TS lint limits.

### Commit Conventions (enforced by CI)
Commits to `main` **must** follow [Conventional Commits](https://www.conventionalcommits.org/) (`type: description`). PRs are squash-merged — the PR title becomes the commit, validated by CI. Changelog is auto-generated from these via git-cliff (`cliff.toml`). See `.agents/skills/commit/SKILL.md` for allowed types and examples.

Changelog is auto-generated from these via git-cliff (`cliff.toml`). See `.agents/skills/commit/SKILL.md` for allowed types and examples.
The commitlint hook caps the header at **100 characters** (`type(scope): description`). The pre-commit prettier hook also reformats staged TS/TSX files - if it does, the commit fails. Re-stage the reformatted files and create a new commit (don't `--amend`).
### Release & Versioning
Kandev uses a **single SemVer** `X.Y.Z` across npm, Homebrew, and GitHub release; release flow runs entirely in CI via `.github/workflows/release.yml`. Full details in the `/release` skill — load it when cutting a release or debugging release artifacts.

- **Execution access:** Workspace-oriented handlers (files, shell, inference, ports, vscode, LSP) MUST use `GetOrEnsureExecution(ctx, sessionID)` — it recovers from backend restarts by creating executions on-demand. Only use `GetExecutionBySessionID` for operations that require a running agent process (prompt, cancel, mode).
- **Task lifecycle events:** Any code path that mutates a task row must publish via the event bus (`task.created` / `task.updated` / `task.deleted`) — either by going through `Service.CreateTask` / `UpdateTask` / `DeleteTask` / `ArchiveTask`, or by calling `publishTaskEvent` (or one of the `Publish*` helpers in `service_events.go`) directly. Walking `repository.TaskRepository` straight bypasses event publishing and breaks WS-driven UI like the All-Workflows kanban view. `HandoffService`'s cascade methods learned this the hard way — they now require a `TaskEventPublisher` wired via `SetTaskEventPublisher`. New cascade / bulk / cleanup paths must follow the same pattern.
- **Testing:** Prefer `testing/synctest` (Go 1.24+) over `time.Sleep` for time-dependent tests. Use `synctest.Test` to wrap tests with tickers or timeouts — it advances fake time instantly when all goroutines are idle. When `synctest` is not feasible (e.g., tests spawning external processes like `git`), use channel-based synchronization (`<-started`, non-blocking `select`) instead of sleep-based waits. Reserve `time.Sleep` only for integration tests that need real subprocess execution time.
### Backups
- On every SQLite boot, `persistence.Provide` reads `kandev_meta.kandev_version`. If the stored version differs from the binary version (or any user tables exist but no version is recorded), it takes a `VACUUM INTO` snapshot into `<data-dir>/backups/` before running migrations.
- Retention: 2 backups kept (newest two by mtime); older ones are pruned after the snapshot succeeds.
- Postgres: backup is skipped with a log line. Use `pg_dump` for Postgres backups.
- Boot aborts if the backup fails -- the pool is closed and `Provide` returns an error.
- After all repos complete `initSchema`, `cmd/kandev/storage.go:recordSchemaVersion` writes the current binary version into `kandev_meta` (non-fatal; a failure just means the next boot will take a fresh snapshot).
- Migration logging: `db.MigrateLogger.Apply(name, stmt)` -- success logs Info, "already exists"/"duplicate column name" is silently swallowed, anything else logs Warn but never returns an error (preserving the existing swallow-error contract).
### Frontend
- **Data:** SSR fetch → hydrate → read store. Never fetch in components
- **UI Components:**
- Import shadcn components from `@kandev/ui`, NOT `@/components/ui/*`
- **Always prefer native shadcn components** over custom implementations
- Check `apps/packages/ui/src/` for available components (pagination, table, dialog, etc.)
- For data tables, use `@kandev/ui/table` with TanStack Table; use shadcn Pagination components
- Only create custom components when shadcn doesn't provide what's needed
- **Components:** <200 lines, extract to domain components, composition over props
- **Hooks:** Domain-organized in `hooks/domains/`, encapsulate subscription + selection
- **WS:** Use subscription hooks only; client auto-deduplicates
- **Interactivity:** All buttons and links with actions must have `cursor-pointer` class
### Plan Implementation
- After implementing a plan, run `make fmt` first to format code, then run `make typecheck test lint` to verify the changes. Formatting must come first because formatters may split lines, which can trigger complexity linter warnings.

## Key Concepts
**Orchestrator** coordinates task execution:
- Receives task start/stop/resume requests via WebSocket
- Delegates to lifecycle manager for agent operations
- Handles event-driven state transitions via workflow engine
- Located in `internal/orchestrator/`
**Workflow Engine** (`internal/workflow/engine/`) provides typed state-machine evaluation:
- `Engine.HandleTrigger()` evaluates step actions for triggers (on_enter, on_turn_start, on_turn_complete, on_exit)
- `TransitionStore` interface abstracts persistence (implemented by `orchestrator.workflowStore`)
- `CallbackRegistry` maps action kinds to callbacks (plan mode, auto-start, context reset)
- First-transition-wins: multiple transition actions in one trigger, first eligible wins
- `EvaluateOnly` mode: engine evaluates without persisting, caller orchestrates on_exit → DB → on_enter
- `RequiresApproval` on actions: transitions requiring review gating are skipped
- Idempotent by `OperationID`; session-scoped data bag via `MachineState.Data`
**Agent Runtime** (`internal/agent/runtime/`) is the single seam for launching, resuming, stopping, and observing agent executions. ADR 0004 introduced this in Phase 1 of task-model-unification. The public surface is `runtime.Runtime` (`runtime.go`); a thin facade (`facade.go`) delegates to a `Backend` (satisfied by `*lifecycle.Manager`).
**Convention:** only `internal/agent/runtime/` (and code that pre-dates Phase 1 migration) may import `runtime/lifecycle` or `runtime/agentctl` directly. New consumers — workflow engine actions, cron-driven trigger handlers, future task-tier callers — should depend on `runtime.Runtime`. Existing call sites are migrated through later phases of task-model-unification.
**Lifecycle Manager** (`internal/agent/runtime/lifecycle/`) manages agent instances under the runtime:
- `Manager` (`manager.go`, `manager_*.go`) - central coordinator for agent lifecycle
- `ExecutorBackend` interface (`executor_backend.go`) - abstracts execution environment (Docker, Standalone, Sprites, Remote Docker)
- `ExecutionStore` (`execution_store.go`) - thread-safe in-memory execution tracking
- `session.go` - ACP session initialization and resume
- `streams.go` - WebSocket stream connections to agentctl
- `process_runner.go` - agent process launch and management
- `profile_resolver.go` - resolves agent profiles/settings
**agentctl client** (`internal/agent/runtime/agentctl/`) is the HTTP/WS client used by the lifecycle manager to talk to a running agentctl instance. It is a runtime-tier package and should not be imported outside `internal/agent/runtime/`.
**agentctl** is an HTTP server that:
- Runs inside Docker containers or as standalone process
- Manages agent subprocess via stdin/stdout (ACP protocol)
- Exposes workspace operations (shell, git, files)
- Supports multiple concurrent instances on different ports
**Executor Types** (database model):
- `local_pc` - Standalone process on host
- `local_docker` - Docker container on host
- `sprites` - Sprites cloud environment
- `remote_docker`, `remote_vps`, `k8s` - Planned
## Execution Flow
```text
Client (WS) → Orchestrator → Lifecycle Manager → ExecutorBackend (container/process) → agentctl
↓
Client (WS) ← Orchestrator ← Lifecycle Manager ←──── stream updates (WS) ──────── agent subprocess
```
1. Orchestrator receives `session.launch` via WS
2. Lifecycle Manager creates executor instance (container or process)
3. agentctl starts inside the instance, agent subprocess is configured and started
4. Agent events stream back via WS through the chain
**Session Resume:** `TaskSession.ACPSessionID` stored for resume; `ExecutorRunning` tracks active state; on restart `RecoverInstances()` reconnects.
**Provider Pattern:** Packages expose `Provide(cfg, log) (*impl, cleanup, error)` for DI. Returns implementation, cleanup function, and error. Cleanup called during graceful shutdown.
**Worktrees:** `internal/worktree/Manager` provides workspace isolation. Each session can have its own worktree (branch) to prevent conflicts between concurrent agents.
**Executor default scripts:** Default prepare scripts are in `internal/agent/runtime/lifecycle/default_scripts.go`; `internal/scriptengine/` handles placeholder resolution.
## Conventions
- Provider pattern for DI; stderr for logs, stdout for ACP only.
- Pass context through chains; event bus for cross-component comm.
- **Execution access:** Workspace-oriented handlers (files, shell, inference, ports, vscode, LSP) MUST use `GetOrEnsureExecution(ctx, sessionID)` — it recovers from backend restarts by creating executions on-demand. Only use `GetExecutionBySessionID` for operations that require a running agent process (prompt, cancel, mode).
- **Task lifecycle events:** Any code path that mutates a task row must publish via the event bus (`task.created` / `task.updated` / `task.deleted`) — either by going through `Service.CreateTask` / `UpdateTask` / `DeleteTask` / `ArchiveTask`, or by calling `publishTaskEvent` (or one of the `Publish*` helpers in `service_events.go`) directly. Walking `repository.TaskRepository` straight bypasses event publishing and breaks WS-driven UI like the All-Workflows kanban view. `HandoffService`'s cascade methods learned this the hard way — they now require a `TaskEventPublisher` wired via `SetTaskEventPublisher`. New cascade / bulk / cleanup paths must follow the same pattern.
- **Testing:** Prefer `testing/synctest` (Go 1.24+) over `time.Sleep` for time-dependent tests. Use `synctest.Test` to wrap tests with tickers or timeouts — it advances fake time instantly when all goroutines are idle. When `synctest` is not feasible (e.g., tests spawning external processes like `git`), use channel-based synchronization (`<-started`, non-blocking `select`) instead of sleep-based waits. Reserve `time.Sleep` only for integration tests that need real subprocess execution time.
## Backups
- On every SQLite boot, `persistence.Provide` reads `kandev_meta.kandev_version`. If the stored version differs from the binary version (or any user tables exist but no version is recorded), it takes a `VACUUM INTO` snapshot into `<data-dir>/backups/` before running migrations.
- Retention: 2 backups kept (newest two by mtime); older ones are pruned after the snapshot succeeds.
- Postgres: backup is skipped with a log line. Use `pg_dump` for Postgres backups.
- Boot aborts if the backup fails — the pool is closed and `Provide` returns an error.
- After all repos complete `initSchema`, `cmd/kandev/storage.go:recordSchemaVersion` writes the current binary version into `kandev_meta` (non-fatal; a failure just means the next boot will take a fresh snapshot).
- Migration logging: `db.MigrateLogger.Apply(name, stmt)` — success logs Info, "already exists" / "duplicate column name" is silently swallowed, anything else logs Warn but never returns an error (preserving the existing swallow-error contract).
## Code-quality limits
Enforced by `apps/backend/.golangci.yml` (errors on new code only):
- Functions: ≤80 lines, ≤50 statements
- Cyclomatic complexity: ≤15 · Cognitive complexity: ≤30
- Nesting depth: ≤5 · Naked returns only in functions ≤30 lines
- No duplicated blocks (≥150 tokens) · Repeated strings → constants (≥3 occurrences)
When you hit a limit, extract a helper function. Prefer composition over growing a single function.

- `internal/agentctl/server/api/AGENTS.md` — reverse-proxy body rewriting (`Accept-Encoding`), iframe-blocking header stripping

# agentctl — HTTP server, adapters, ACP protocol
Scoped guidance for `apps/backend/internal/agentctl/`. Higher-level backend architecture is in `apps/backend/AGENTS.md`.
## API Groups
agentctl exposes these route groups (see `server/api/`):
- `/health`, `/info`, `/status` - Health and status
- `/instances/*` - Multi-instance management
- `/processes/*` - Agent subprocess management (start/stop)
- `/agent/configure`, `/agent/stream` - Agent configuration and event streaming
- `/git/*` - Git operations (status, commit, push, pull, rebase, stage, etc.)
- `/shell/*` - Shell session management
- `/workspace/*` - File operations, search, tree
- `/vscode/*` - VS Code integration proxy
## Adapter Model
Protocol adapters in `server/adapter/transport/` normalize different agent CLIs:
- `AgentAdapter` interface defines `Start()`, `Stop()`, `Prompt()`, `Cancel()`
- Transports: `acp` (Claude Code), `codex` (OpenAI Codex), `opencode`, `shared`, `streamjson`
- Top-level adapters: `CopilotAdapter` (GitHub Copilot SDK), `AmpAdapter` (Sourcegraph Amp)
- `process.Manager` owns subprocess, wires stdio to adapter
- Factory pattern in `server/adapter/factory.go` selects adapter by agent type
## ACP Protocol
JSON-RPC 2.0 over stdin/stdout between agentctl and agent process. Requests: `initialize`, `session/new`, `session/load`, `session/prompt`, `session/cancel`. Notifications: `session/update` with types `message_chunk`, `tool_call`, `tool_update`, `complete`, `error`, `permission_request`, `context_window`.

# agentctl API package notes
Scoped guidance for `apps/backend/internal/agentctl/server/api/`. Covers patterns that aren't obvious from reading the code in isolation.
## Reverse-proxy body rewriting (`port_proxy.go`)
The port proxy's `ModifyResponse` hook scans HTML responses to inject the inspector script (`html_injector.go`). For that scan to work, the body must arrive uncompressed.
**Don't decompress manually.** Instead, in the `Rewrite` hook, delete `Accept-Encoding` on the outbound request:
```go
r.Out.Header.Del("Accept-Encoding")
```
`net/http.Transport` then adds its own `Accept-Encoding: gzip` and auto-decompresses *before* `ModifyResponse` runs. Leaving the client's value intact (e.g. `gzip, br, deflate`) skips Transport's auto-decompression — the body arrives compressed and any byte scan corrupts it.
After rewriting the body in `injectScriptsIntoResponse`:
- `resp.Header.Del("Content-Encoding")`
- Set both `resp.Header["Content-Length"]` and `resp.ContentLength` (forgetting either causes chunked-encoding mismatches in the browser).
Tested in `port_proxy_test.go::TestCreatePortProxy_StripsAcceptEncodingAndInjectsHTML`.
## Iframe-blocking headers
`stripIframeSecurityHeaders` removes `Content-Security-Policy`, `Content-Security-Policy-Report-Only`, and `X-Frame-Options` from proxied HTML responses. This is scoped to HTML responses only (gated by `Content-Type` in `ModifyResponse`); other content types pass through with headers intact.

# Adding a new third-party integration
Jira and Linear are the model: per-workspace credentials, a 90s auth-health poller, a settings page with status banner + reconnect CTA, link/import buttons that gate on availability. New integrations should reuse the shared shapes in this folder rather than copying either.
This file covers both halves of the playbook (backend + frontend) so the pattern is readable in one place.
## Backend (`apps/backend/internal/<name>/`)
- Mirror the package layout: `service.go`, `store.go`, `client.go`, `provider.go`, `handlers.go`, `models.go`, `poller.go`. Expose `Provide(writer, reader *sqlx.DB, secrets SecretStore, eventBus bus.EventBus, log *logger.Logger) (*Service, func() error, error)`. Pass `nil` for `eventBus` when the integration doesn't publish events; both Jira and Linear take and use it for issue-watch publishing.
- Use `internal/integrations/secretadapter` instead of writing your own upsert wrapper around `secrets.SecretStore`. The adapter satisfies any per-integration `SecretStore` interface shaped as `{Reveal, Set, Delete, Exists}`.
- Use `internal/integrations/healthpoll` for the auth-health loop. Implement the `Prober` interface (`ListConfiguredWorkspaces` + `RecordAuthHealth`) on a small adapter and let `healthpoll.New("name", prober, log)` own Start/Stop/ticker. Keep integration-specific loops (JQL polling, webhook reconciliation, etc.) separate, like jira's issue-watch loop.
- Wire the service via a per-domain `init<Name>Service(...)` helper in `cmd/kandev/services.go`, not inline in `provideServices`.
- Ship a `mock_client.go` + `mock_controller.go` next to the real client. `Provide` branches on `KANDEV_MOCK_<NAME>=true` and returns the in-memory client; `RegisterMockRoutes(router, svc, log)` mounts `/api/v1/<name>/mock/*` only when the service was built with the mock. The e2e backend fixture sets the env var so Playwright tests drive the mock via `apiClient.mock<Name>*()` helpers — see jira/linear for the layout.
## Frontend (`apps/web/`)
- Hooks live under `hooks/domains/<name>/`, **not** `components/<name>/`.
- Use `hooks/domains/integrations/use-integration-availability.ts` and `use-integration-enabled.ts` — each integration's `useXAvailable` / `useXEnabled` should be a one-line wrapper passing the storage key + sync event + config-fetch function.
- Settings page reuses `<IntegrationAuthStatusBanner>` (`components/integrations/auth-status-banner.tsx`).
- "Auth required / reconnect" UI reuses `<IntegrationAuthErrorMessage>` (`components/integrations/auth-error-message.tsx`) — supply the integration's display name, regex check, and reconnect href.
- Link / import popovers reuse `<ValidatedPopover>` (`components/integrations/validated-popover.tsx`) — supply the icon, label, key regex, fetch function, and success callback.
## Where Jira and Linear deliberately diverge
- **Issue model:** Jira uses transitions + JQL; Linear uses state IDs + structured filters. Don't merge these schemas — the upstream APIs are genuinely different.
- **Watch filter persistence:** Jira stores the JQL string verbatim; Linear stores the structured `SearchFilter` as JSON in `filter_json` (Linear has no JQL equivalent). The orchestrator emits `NewJiraIssueEvent` / `NewLinearIssueEvent` respectively and dedups by issue key (Jira) vs identifier (Linear).
- **Health column extras:** Linear's `linear_configs` row carries an `org_slug` captured from successful probes; Jira's row does not.

# Frontend (Next.js) — architecture and conventions
Scoped guidance for `apps/web/`. Repo-wide rules (commit format, code-quality limits, etc.) live in the root `AGENTS.md`.
## UI Components
**Shadcn Components:** Import from `@kandev/ui` package:
```typescript
import { Badge } from "@kandev/ui/badge";
import { Button } from "@kandev/ui/button";
import { Dialog } from "@kandev/ui/dialog";
// etc...
```
**Do NOT** import from `@/components/ui/*` - always use `@kandev/ui` package.
- Always prefer native shadcn components over custom implementations.
- Check `apps/packages/ui/src/` for available components (pagination, table, dialog, etc.).
- For data tables, use `@kandev/ui/table` with TanStack Table; use shadcn Pagination components.
- Only create custom components when shadcn doesn't provide what's needed.
## Data Flow Pattern (Critical)
```text
SSR Fetch -> Hydrate Store -> Components Read Store -> Hooks Subscribe
```
**Never fetch data directly in components.**
## Store Structure (Domain Slices)
```text
lib/state/
├── store.ts # Root composition
├── default-state.ts # Default state + initial state merge
├── slices/ # Domain slices
│ ├── kanban/ # boards, tasks, columns
│ ├── session/ # sessions, messages, turns, worktrees
│ ├── session-runtime/ # shell, processes, git, context
│ ├── workspace/ # workspaces, repos, branches
│ ├── settings/ # executors, agents, editors, prompts (incl. userSettings)
│ ├── comments/ # code review diff comments
│ ├── github/ # GitHub PRs, reviews
│ └── ui/ # preview, connection, active state, sidebar views
├── hydration/ # SSR merge strategies
hooks/domains/{kanban,session,workspace,settings,comments,github}/ # Domain-organized hooks
lib/api/domains/ # API clients
├── kanban-api, session-api, workspace-api, settings-api, process-api
├── plan-api, queue-api, workflow-api, stats-api, github-api
├── user-shell-api, debug-api, secrets-api, sprites-api, vscode-api
├── health-api, utility-api
```
**Key State Paths:**
- `messages.bySession[sessionId]`, `shell.outputs[sessionId]`, `gitStatus.bySessionId[sessionId]`
- `tasks.activeTaskId`, `tasks.activeSessionId`, `workspaces.activeId`
- `repositories.byWorkspace`, `repositoryBranches.byRepository`
**Hydration:** `lib/state/hydration/merge-strategies.ts` has `deepMerge()`, `mergeSessionMap()`, `mergeLoadingState()` to avoid overwriting live client state. Pass `activeSessionId` to protect active sessions.
**Hooks Pattern:** Hooks in `hooks/domains/` encapsulate WS subscription + store selection. WS client deduplicates subscriptions automatically.
## WebSockets
**Format:** `{id, type, action, payload, timestamp}`.
Use subscription hooks only; the WS client auto-deduplicates.
## Component conventions
- Components: <200 lines, extract to domain components, composition over props.
- Hooks: domain-organized in `hooks/domains/`, encapsulate subscription + selection.
- **Interactivity:** all buttons and links with actions must have `cursor-pointer` class.
## Code-quality limits
Enforced by `apps/web/eslint.config.mjs` (warnings, will become errors):
- Files: ≤600 lines · Functions: ≤100 lines
- Cyclomatic complexity: ≤15 · Cognitive complexity: ≤20
- Nesting depth: ≤4 · Parameters: ≤5
- No duplicated strings (≥4 occurrences) · No identical functions · No unused imports
- No nested ternaries
When you hit a limit, extract a helper function, custom hook, or sub-component. Prefer composition over growing a single function.
