feat(workflow): explicit step-completion signal for auto-advance (#1276)
* feat(workflow): explicit step-completion signal for auto-advance Adds `step_complete_kandev` MCP tool + `WorkflowStep.auto_advance_requires_signal` column so workflow steps can gate their `on_turn_complete` transitions on an agent-emitted completion signal instead of inferring "done" from any turn-end. See docs/decisions/0015-explicit-completion-signal-for-auto-advance.md for the motivation, alternatives considered, and trade-offs. * fix(workflow): address PR review feedback for explicit completion signal - Dedup `LoadPendingStepSignal` into `internal/task/models` so the MCP handler (write site) and the orchestrator (read site) share one decoder. - Gate the out-of-band subscriber on `WorkflowStep.AutoAdvanceRequiresSignal` so `step_complete_kandev` is not an unintended manual-advance path for signalless steps. - Fail closed on step-load errors in `processOnTurnCompleteViaEngine`: a loader hiccup must block the transition rather than silently bypass the gate. - Reject `step_complete_kandev` for terminal sessions (Completed / Failed / Cancelled) so the agent gets a clear error instead of `accepted: true` followed by a no-op. - Surface bus-publish failures back to the agent instead of swallowing them — the idempotency guard makes the retry safe and prevents the session from getting stuck. - New `TestOnStepCompletionSignaled` covers the subscriber paths (RUNNING / WAITING+match / stale step / not signal-gated). - ADR doc fixes: payload field list now matches the wire shape, writer ownership is documented, the unsubstantiated 250ms-debounce claim is removed, and the late-signal re-close race is recorded as a deferred open question. - Drop the new toggle's HelpTip in favour of an inline description — the shadcn tooltip portal was intercepting clicks on the agent-profile dropdown options in the workflow settings E2E. * fix(workflow): round-2 review fixes for explicit completion signal - Split `handleStepComplete` into `resolveStepCompleteTarget` + `publishStepCompletionEvent` helpers so the entrypoint clears funlen (88 → under 80 lines) and the two halves are independently testable. - Classify session/task load errors instead of returning `NotFound` for every failure: use the exported `taskrepo.ErrTaskNotFound` sentinel for task lookups, substring-match for the session repo (no sentinel today), and surface anything else as `InternalError` with the raw error logged but not leaked to the agent — so a transient DB hiccup triggers a retry rather than session abandonment. - Pin `step_complete_kandev` explicitly in the mode-specific tool-count tests: `Contains` in `ModeTask`, `NotContains` in `ModeConfig` and `ModeOffice`, so accidental dereg or cross-mode registration is caught by the diff instead of by a still-equal count. * fix(workflow): round-3 review fixes + defer pipeline-editor toggle - Defer the "Wait for agent completion signal" sub-toggle to a follow-up PR. Adding it to the step config card shifts the layout enough that the agent profile select's Radix popper opens into a sibling tooltip's hover path, breaking workflow-agent-profile.spec.ts on shard 7. The backend column ships in this PR — workflows can opt in via the YAML import or the MCP `update_workflow_step_kandev` tool — and the UI affordance gets its own iteration where the test interference can be investigated without blocking the rest of the change. - Re-publish the bus event on the `already_signaled` short-circuit when the session is WAITING_FOR_INPUT. Without this, an agent's retry after the first call's publish failed would short-circuit on the persisted bag, never fire the subscriber, and leave the session stuck. - handleStepComplete docstring: drop the non-existent feature-flag claim and the "audit entry" wording — gating is purely `WorkflowStep.AutoAdvanceRequiresSignal` and the bag is cleared on the next turn start with no separate audit trail. - `step_complete_kandev` tool description: same fix — clarify that the call succeeds for non-gated steps but the signal is discarded on the next turn start (no audit history to query later). * test(workflow): cover handleStepComplete + reword defer-comment - Add `TestHandleStepComplete_*` (6 subtests, all passing) covering the uncovered handler paths flagged by Claude/cubic on round 3: missing-fields validation, session-does-not-belong-to-task ownership guard, terminal-session rejection (Completed/Failed/Cancelled), first-call happy path (bag persisted + bus payload shape pinned), dedup while RUNNING (no re-publish), and dedup while WAITING_FOR_INPUT (the retry-after-publish-failure path — must re-publish so the subscriber fires). - Reword the deferred-toggle comment to drop the YAML-export claim: the workflow export model doesn't yet serialize `auto_advance_requires_signal`, so MCP `update_workflow_step_kandev` is the only configuration path that round-trips today. Note the follow-up needs to extend the export schema alongside the UI toggle. * test(workflow): pin signaled_at + drop redundant GetTaskSession on bag-clear - Assert `signaled_at` is present and parses as RFC3339Nano in `TestHandleStepComplete_FirstCallAccepted`. The field is part of the handler's documented response contract; pinning it catches accidental drop/rename regressions. - Add `clearPendingStepSignalByID(ctx, sessionID)` as a thin DB-only variant of `clearPendingStepSignal` and use it from `executeStepTransition`, where the session struct isn't read after the clear. Avoids an extra `GetTaskSession` round-trip per transition. `clearPendingStepSignal(session)` still exists for the in-memory-mutation case (subscriber's stale-step path). * fix(workflow): subscriber stale-clear guard + ADR/comment drift fixes - onStepCompletionSignaled's stale-step path now reads the bag and only clears it when its current StepID matches the (stale) event's stepID. Previously the unconditional clear could destroy a valid signal that the new step's agent had just written when sessions are reused across steps without auto_start_agent. (Greptile P1.) - Drop the "feature flag" phrase from WorkflowStep.AutoAdvanceRequiresSignal docstring — leftover from an earlier draft. The gating is purely the boolean field; the global flag was removed two rounds ago. - Merge the two adjacent `if triggerOnEnter` blocks in executeStepTransition so the full triggerOnEnter=true path reads top- to-bottom in one place. (CodeRabbit + cubic.) - ADR 0015 Mechanism section: re-label the SessionStepHistory.Metadata audit annotation, the `step_complete_signaled` system message, and the expvar telemetry counters as deferred. They're planned shapes, not current behaviour — calling them "Audit" / "Chat visibility" / "Telemetry" in present tense was misleading for future readers. * fix(workflow): drop subscriber complexity + reload session on stale-clear - Extract `parseStepCompletionEvent` and `stepIsSignalGated` helpers from `onStepCompletionSignaled`. Cyclomatic complexity goes 17 → under 15 (cyclop on new code, CI lint regression after the round-6 stale-clear guard). - The stale-step branch now re-loads the session from the DB before deciding whether to clear the bag. The previous round-6 fix checked the local `session.Metadata` snapshot, which can be older than a concurrent write from the new step's agent — that check could see a stale signal that had since been overwritten with a valid one and erase the new bag entry. The narrower load-on-clear is cheap and closes the cubic P1 hole. (The broader race in `processOnTurnCompleteViaEngine` reading session.Metadata is the monotonic-marker open question in ADR 0015; out of scope here.) * test(workflow): pin stale-event guard's preserve-current-bag side + dedup StringFromAny - Add `TestOnStepCompletionSignaled` subtest "stale event → valid bag for CURRENT step is preserved" — fires a stale step-A event while the bag holds a valid step-B signal, asserts the bag still contains StepID=step_b after the subscriber runs. Pins the negative side of the round-6 `existing.StepID == stepID` guard, so a regression that drops or inverts the guard (and would silently leave signal-gated steps stuck) fails the test instead of slipping through. - Promote `pendingSignalString` to exported `models.StringFromAny` and reuse it from the orchestrator subscriber's `parseStepCompletionEvent`. Eliminates the byte-for-byte duplicate helper across the two packages; the bag-shape decoder and the bus- event decoder now share one source of truth for "missing string". --------- Co-authored-by: Kandev Agent <agent@kandev.dev> |

feat(tasks): multi-branch tasks — N (repo, branch) pairs per task (#1226)
* feat(tasks): multi-branch tasks — N (repo, branch) pairs per task Extends multi-repo into multi-branch so a single task can hold multiple worktrees on the same repo (one per branch). Sibling worktrees layout at <task>/<repo>/ + <task>/<repo>-<slug>/, dedicated PRWatch per branch, live agentctl tracker rescan + frontend store updates so the UI splits PRs / files / commits per branch without a session restart. MCP add_branch_to_task_kandev tool is shielded to the worktree executor. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> * fix(web): unify multi-branch repo label as <repo> · <branch> across panels PR Changes and Commits panels rendered repo labels differently for multi-branch tasks — Commits showed "kandev · feature/x" while PR Changes leaked the raw "kandev-feature-x" agentctl tracker tag. Reformat tracker-tagged repo names via formatRepoLabel using the longest known-repo prefix so kandev-cli-* doesn't collapse to kandev · cli-*. * fix(tasks): address multi-branch PR review — data races, slug collisions, MCP error codes Backend - agentctl process.Manager: add repoTrackersMu RWMutex guarding repoTrackers + workspaceTracker. Reads snapshot under RLock; RescanRepositories builds trackers first, takes Lock for swap/append. Validates newWorkDir via os.Stat before publishing cfg.WorkDir. - worktree.Manager: reject invalid explicit BranchSlug up-front; cache key uses sanitized wt.BranchSlug so read/write paths are symmetric. - worktree.store: narrow isDuplicateColumnError to "duplicate column name". - task service AddBranchToTask: slug-collision guard rejects feat/a vs feat-a. - orchestrator resolvePushRepo: two-pass exact-name match before subdir prefix fallback so "backend" doesn't swallow pushes for "backend-admin". - executor buildRepoSpecs: duplicate repos always get a non-empty BranchSlug (falls back to branch-N when both branch fields sanitize to empty). - MCP handler: classifyAddBranchError maps service errors to NOT_FOUND / CONFLICT / VALIDATION_ERROR; add ErrorCodeConflict constant. - MCP server: extract registerAddBranchToTaskTool, register in task mode only (external mode contract: config tools + create_task_kandev). - workspace_rescan handler: reject malformed JSON with 400 instead of silently rescanning the current root. - branch_materializer: split MaterializeBranch into prepare + finalize helpers to satisfy the 80-line cap. Frontend - existingPrUrl returns undefined when a task has >1 PR so per-repo View PR buttons take over (no silent linking to a sibling). - formatRepoLabel checks exact known-repo match before prefix splitting so "kandev-cli" isn't mislabeled as "kandev · cli". - Repo chip key now includes base_branch so siblings differing only on base render as distinct chips. Docs - multi-branch spec uniqueness wording aligned with the canonical 4-column key (task_id, repository_id, base_branch, checkout_branch). - worktree.CreateRequest.BranchSlug doc describes the sibling layout (<repo>-<slug>) instead of the obsolete nested form. * fix(tasks): scope slug-collision check to repo only + use errors.Is for ErrTaskNotFound - service_branches: drop base_branch from the slug-collision check. Worktree path is (repo, slug); two rows on the same repo cut from different bases still collide on disk. - service_branches: prepareBranchAdd wraps taskrepo.ErrTaskNotFound via fmt.Errorf with %w so classifiers don't have to substring-match the formatted task UUID. - mcp handlers: classifyAddBranchError uses errors.Is(err, ErrTaskNotFound). * fix(agentctl): sanitize rescan work_dir before os.Stat to clear CodeQL path-injection CodeQL flagged the rescan endpoint as a path-injection sink (the HTTP-supplied work_dir flowed straight into os.Stat and downstream scanRepositorySubdirs). Add validateRescanPath which: - requires the input to be a clean absolute path with no ".." segments - rejects anything that isn't equal to or an ancestor of the current cfg.WorkDir — the only legitimate use case is the branch materializer promoting <task>/<repo>/ to <task>/ Defense in depth: agentctl binds to localhost, but any colocated process could otherwise direct it at /etc or the user's home by POSTing /api/v1/workspace/rescan. * fix(agentctl): tighten validateRescanPath, close TOCTOU on existingTrackers, add tests - Drop the strings.Contains(clean, "..") guard. filepath.Clean already resolves traversal; the substring check rejects legitimate names like /home/u/..hidden without adding defense (the ancestor check via filepath.Rel is the real boundary). - Drop the rel == "." branch in the ancestor check — early return for clean == currentClean already covers identity. - Read existingTrackers inside the write-lock section (not under RLock then re-Lock) so two concurrent rescans can't both see 0 trackers and double-bootstrap the multi-repo set. - Add table-driven TestValidateRescanPath covering rejection paths (relative, descendant, sibling, traversal-cleaned, empty input), legitimate ancestor promotion, exact match, no-anchor first-launch, and a /home/u/..hidden dotted-segment case. * fix(agentctl): break taint flow into os.Stat — derive rescan path from cfg, not HTTP body CodeQL's go/path-injection trace still flagged manager_rescan.go after the prior sanitizer because the user-supplied newWorkDir flowed (after validation) into os.Stat and then into cfg.WorkDir → tracker paths → workspace_monitor os.Stat sinks. Replace validateRescanPath with resolveRescanPath: it returns a path DERIVED from currentWorkDir (no-op = currentClean, promotion = filepath.Dir(currentClean)) and uses newPath only for comparison, never as a source for the returned string. os.Stat now receives a path whose provenance is trusted manager config. Functionally the legitimate caller (branch materializer promoting <task>/<repo>/ to <task>/) is unchanged. * test(agentctl): make TestResolveRescanPath windows-portable The Linux Backend Tests job passed but the Backend (windows) job rejected every "absolute" case because filepath.IsAbs("/task/repo") is false on Windows (no volume letter). Build inputs via filepath.Join against absRoot() (filepath.Abs of "/" / "\\") so the same table covers POSIX (`/...`) and Windows (`C:\...`) without per-OS branches. Keep the traversal-after-Clean case POSIX-only since filepath.Clean is the shared primitive and that input form needs a volume to be considered absolute on Windows anyway. * fix(agentctl): serialize RescanRepositories + re-check trackers under write lock Two concurrent RescanRepositories calls could both observe an empty tracker set (between the snapshot read and the bootstrap branch) and both enter transitionToMultiRepoMode, leaking a duplicate bare-root tracker and duplicate per-repo trackers. Same race in appendNewRepoTrackers would double-append the same new child across both callers. Fix: - Add rescanMu sync.Mutex on Manager. Acquired for the full body of RescanRepositories so the snapshot → branch → mutate sequence is serialized. repoTrackersMu still guards individual field reads from unrelated goroutines (subscribe/unsubscribe/poll-mode). - appendNewRepoTrackers re-checks membership inside the write-lock before appending and drops already-present trackers (Stop + detach outside the lock). Defense in depth. - Test: add `dotted segment is legal as promotion` case so the ..hidden-segment promotion path stays exercised. --------- Co-authored-by: Kandev Agent <agent@kandev.dev> Co-authored-by: Claude Opus 4.7 <noreply@anthropic.com> |
