Output Policy & Context Management

English ONLY; technical, direct, concise (no conversational fillers). Record only compact envelopes from x-implement-task (status/taskId/commitSha/coverage*) — no full TDD logs. Reference plan/review files by path (+score for reviews); never re-load content. Read story file once in Phase 0 via x-internal-load-story-context. Delegate every state mutation to x-internal-update-status.

Skill: Story Implementation (Thin Orchestrator — ADR-0012 + EPIC-0049)

Orchestrate story end-to-end via delegation. Inline: argv parse (delegate), load context (delegate), drive task loop (x-implement-task), close story-level PR. Zero direct git/gh/mvn calls.

EPIC-0049 flag propagation (OO-style — RULE-009): --target-branch <branch> (default develop) → x-implement-task + x-create-pr; --auto-merge <strategy> (default none) → x-create-pr; --epic-id <ID> (auto-derived from storyId) → x-create-pr (adds epic-XXXX label). All flags absent = EPIC-0048 behavior (backward compat — RULE-008).

Triggers

• /x-implement-story story-XXXX-YYYY — full lifecycle (legacy default: target=develop, no auto-merge)
• /x-implement-story story-XXXX-YYYY --target-branch epic/0049 --auto-merge merge --epic-id 0049 — orchestrator-propagated run targeting an epic branch
• /x-implement-story story-XXXX-YYYY --task TASK-NNN — execute only a specific task (resume / targeted)
• /x-implement-story story-XXXX-YYYY --resume — continue from execution-state.json via x-internal-resume-story
• /x-implement-story story-XXXX-YYYY --auto-approve-pr — parent-branch mode (RULE-004)
• /x-implement-story story-XXXX-YYYY --worktree — standalone opt-in worktree (ADR-0004 Mode 2)
• /x-implement-story story-XXXX-YYYY --interactive — opt-in to gate menus (PROCEED/FIX-PR/ABORT)

Review Policy — MANDATORY — NON-NEGOTIABLE: Specialist (x-review-codebase) + Tech-Lead (x-review-pr) reviews in Step 3.2 MUST execute unless --skip-verification / --skip-review; silent omission is a PROTOCOL_VIOLATION and subagents MUST abort with "REVIEW_SKIPPED_WITHOUT_FLAG".

Phase 0 — Args, Context & Resume

<!-- TELEMETRY: phase.start -->

Bash command: $CLAUDE_PROJECT_DIR/.claude/hooks/telemetry-phase.sh start x-implement-story Phase-0-Prepare

Skill(skill: "x-internal-verify-phase-gates", model: "haiku", args: "--mode pre --skill x-implement-story --phase Phase-0-Context")

Open phase tracker (close with TaskUpdate(id: phase0TaskId, status: "completed") after §0.4):

TaskCreate(subject: "{STORY_ID} › Phase 0 - Context", activeForm: "Loading story context and resume state")

0.1 Args normalization (Rule 13 Pattern 1)

Skill(skill: "x-internal-normalize-args", args: "--schema @references/args-schema.json --argv \"{raw argv}\"")

Consume {parsed, warnings, errors}: exit ARGS_INVALID on errors; print warnings once; extract storyId, epicId (auto-derived from storyId prefix), targetBranch, autoMerge, and all flags (skipReview/skipVerification/skipSmoke/autoApprovePr/nonInteractive/worktree/task/resume/noAutoRemediation/noCiWatch/fullLifecycle) for phase propagation.

0.1a Persist interactiveMode (EPIC-0068)

Write the resolved interactive mode to execution-state.json so the Stop hook enforce-continuous-flow.sh can determine whether to emit nudges:

Skill(skill: "x-internal-update-status", args: "--file ai/epics/epic-XXXX/execution-state.json --type story --id <STORY-ID> --field interactiveMode --value <interactive|non-interactive>")

Value is "interactive" when --interactive flag was passed or CLAUDE_LEGACY_INTERACTIVE=1; otherwise "non-interactive" (Rule 20 default, EPIC-0061).

0.2 Load story context

Skill(skill: "x-internal-load-story-context", args: "--story-id <STORY-ID> --epic-id <EPIC-ID>")

Sub-skill reads story, validates predecessors, runs 7-artifact staleness pre-check (arch/impl/test/tasks/security/compliance/per-task plans), classifies scope (SIMPLE/STANDARD/COMPLEX), detects planningMode (PRE_PLANNED/HYBRID/INLINE). Envelope: {storyPath, tasksCount, scope, planningMode, predecessorsComplete, artifactFreshness[]}. Non-zero → STORY_NOT_LOADABLE.

0.3 Worktree-first branch decision (Rule 14 + ADR-0004)

Skill(skill: "x-manage-worktrees", args: "detect-context") → apply 3-way decision (REUSE/CREATE/LEGACY); set STORY_OWNS_WORKTREE in-memory. Full table in references/full-protocol.md §1.

0.4 Resume (conditional on --resume)

Skill(skill: "x-internal-resume-story", args: "--story-id <STORY-ID> --epic-id <EPIC-ID>")

Envelope: {resumePoint, tasksCompleted[], tasksPending[], lastCommitSha, staleWarnings[]}. Use tasksPending as Phase 2 iteration filter; print staleWarnings once.

Skill(skill: "x-internal-verify-phase-gates", model: "haiku", args: "--mode post --skill x-implement-story --phase Phase-0-Context")

TaskUpdate(id: phase0TaskId, status: "completed")

<!-- TELEMETRY: phase.end -->

Bash command: $CLAUDE_PROJECT_DIR/.claude/hooks/telemetry-phase.sh end x-implement-story Phase-0-Prepare ok

Phase 0 completed. Proceeding to Phase 1 (Plan)...

<!-- phase-no-gate: API-First is conditional — only activates for stories with contract interfaces; gates live inside the conditional block -->

Phase 0.5 — API-First Contract Generation (Conditional)

Activates ONLY when has_contract_interfaces=True (story declares interfaces of type rest, grpc, event-consumer, event-producer, or websocket). Open phase tracker when active:

TaskCreate(subject: "{STORY_ID} › Phase 0 - API Contract", activeForm: "Generating API-first contracts")

Generates draft OpenAPI 3.1 / Protobuf 3 / AsyncAPI 2.6 in contracts/{STORY_ID}-*.yaml|proto, validates via x-lint-contract-tests, and pauses at Step 0.5.4 via AskUserQuestion (EPIC-0043 gate — replaces legacy CONTRACT PENDING APPROVAL text). Full interface-to-format mapping table and generator details live in references/full-protocol.md §2.

TaskUpdate(id: phase05TaskId, status: "completed")

Phase 1 — Plan

<!-- TELEMETRY: phase.start -->

Bash command: $CLAUDE_PROJECT_DIR/.claude/hooks/telemetry-phase.sh start x-implement-story Phase-1-Plan

Skill(skill: "x-internal-verify-phase-gates", model: "haiku", args: "--mode pre --skill x-implement-story --phase Phase-1-Plan")

Open phase tracker (close with TaskUpdate(id: phase1TaskId, status: "completed") after parallelism gate):

TaskCreate(subject: "{STORY_ID} › Phase 1 - Plan", activeForm: "Orchestrating parallel planning wave")

Batch A — emit 6 planner task trackers in ONE message (SIMPLE scope skips security+compliance). One TaskCreate per planner (Arch plan / Impl plan / Test plan / Task breakdown / Security assessment / Compliance assessment). Store IDs: plannerTasks = {arch, impl, test, tasks, security, compliance}.

TaskCreate(subject: "{STORY_ID} › Phase 1 › Arch plan", activeForm: "Running arch plan")
[+5 siblings per above naming] — see `references/full-protocol.md` §Phase-1-Planning-Wave for exhaustive list.

Batch B — after x-internal-build-story-plan returns, emit 6 TaskUpdate(id: plannerTasks.X, status: "completed") in ONE message (arch/impl/test/tasks/security/compliance).

TaskUpdate(id: plannerTasks.arch, status: "completed")
TaskUpdate(id: plannerTasks.impl, status: "completed")
TaskUpdate(id: plannerTasks.test, status: "completed")
TaskUpdate(id: plannerTasks.tasks, status: "completed")
TaskUpdate(id: plannerTasks.security, status: "completed")
TaskUpdate(id: plannerTasks.compliance, status: "completed")

Skipped entirely when planningMode=PRE_PLANNED (all 7 artifacts fresh — logged "[phase-1] skipped — PRE_PLANNED" and proceeding to Phase 2).

Otherwise invoke:

Skill(skill: "x-internal-build-story-plan", args: "--story-id <STORY-ID> --epic-id <EPIC-ID> --scope <SCOPE> [--skip-review]")

The sub-skill orchestrates parallel story-planning (Phase 1 carve-out): invokes x-plan-architecture (Step 1A) then dispatches up to 5 sibling Agent subagents in ONE assistant message for implementation plan, test plan, task breakdown, security assessment, and compliance assessment (Steps 1B-1F). Scope-aware: SIMPLE skips 1E/1F.

Consume the envelope {artifacts: [{name, path, status}], planningMode, scopeResolved}. On non-zero exit → exit with code PLAN_FAILED. Persist the envelope in orchestrator memory — never re-read the artifact files.

Parallelism gate (RULE-004 hotspots)

Invoke Skill(skill: "x-evaluate-parallelism", args: "--scope=story --story=<STORY-ID>") (EPIC-0041 / story-0041-0006). On detected hard/regen collision, degrade the affected wave to serial and record ExecutionState.parallelismDowngrades. Full matrix in references/full-protocol.md §3.

Wave gate — all planning artifacts produced:

Skill(skill: "x-internal-verify-phase-gates", model: "haiku", args: "--mode wave --skill x-implement-story --phase Phase-1-Plan --expected-tasks {planner-task-ids} --expected-artifacts {arch-path},{impl-path},{test-path},{tasks-path},{security-path},{compliance-path}")

Skill(skill: "x-internal-verify-phase-gates", model: "haiku", args: "--mode post --skill x-implement-story --phase Phase-1-Plan")

TaskUpdate(id: phase1TaskId, status: "completed")

<!-- TELEMETRY: phase.end -->

Bash command: $CLAUDE_PROJECT_DIR/.claude/hooks/telemetry-phase.sh end x-implement-story Phase-1-Plan ok

Phase 1 completed. Proceeding to Phase 2 (Task Execution Loop)...

Phase 2 — Task Execution Loop (RULE-001)

<!-- TELEMETRY: phase.start -->

Bash command: $CLAUDE_PROJECT_DIR/.claude/hooks/telemetry-phase.sh start x-implement-story Phase-2-Implement

Skill(skill: "x-internal-verify-phase-gates", model: "haiku", args: "--mode pre --skill x-implement-story --phase Phase-2-Execute")

Open phase tracker (close with TaskUpdate(id: phase2TaskId, status: "completed") after story-level PR):

TaskCreate(subject: "{STORY_ID} › Phase 2 - Execute", activeForm: "Running task execution loop")

Read tasks from ai/epics/epic-XXXX/plans/tasks-story-XXXX-YYYY.md (Section 8 fallback when absent). Apply the tasksPending filter from Phase 0.4 when resuming. For each TASK-XXXX-YYYY-NNN not in DONE/BLOCKED:

Per-task tracking (sequential, chained via addBlockedBy):

currentTaskId = TaskCreate(subject: "{STORY_ID} › Phase 2 › TASK-XXXX-YYYY-NNN", activeForm: "Executing TASK-XXXX-YYYY-NNN")
[if previous task exists]: TaskUpdate(id: previousTaskId, addBlockedBy: [currentTaskId])

... dispatch x-implement-task + x-create-pr ...

TaskUpdate(id: currentTaskId, status: "completed")

2.1 Per-task dispatch

1. Check deps against execution-state.json; unresolved → BLOCKED via x-internal-update-status, skip.
2. Dispatch TDD: Skill(skill: "x-implement-task", model: "sonnet", args: "<TASK-ID> --orchestrated --target-branch <targetBranch> [--auto-merge <strategy>] [--epic-id <EPIC-ID>] [--auto-approve-pr] [--non-interactive]") → RED/GREEN/REFACTOR + atomic commit + push feat/task-XXXX-YYYY-NNN-desc. Returns {status, taskId, commitSha, branchName, coverageLine, coverageBranch}.
3. CI-watch (Rule 21 + Rule 45): unless --no-ci-watch. MANDATORY TOOL CALL — NON-NEGOTIABLE (Rule 24): Skill(skill: "x-watch-pr-ci", args: "--branch <branchName>") — 8 exit codes. Persists .claude/state/pr-watch-{PR}.json; absence on a merged PR fails Camada 3 audit.
4. PR creation (RULE-009 OO propagation): Skill(skill: "x-create-pr", model: "haiku", args: "<TASK-ID> --target-branch <targetBranch> --auto-merge <strategy> --epic-id <EPIC-ID> [--auto-approve-pr]"). With --auto-approve-pr, task-PR target becomes parent story branch. Consume {prUrl, prNumber, prMergeStatus}.
5. Status: Skill(skill: "x-internal-update-status", args: "--file ai/epics/epic-XXXX/execution-state.json --type task --id <TASK-ID> --field status --value <STATUS>").

2.2 Fail-fast + story-level PR

On status=FAILED, mark dependants BLOCKED and exit Phase 2 with TASK_FAILED (unless --task — single-task mode). When --auto-approve-pr is set, after all tasks succeed push parent branch and create story-level PR:

Skill(skill: "x-create-pr", model: "haiku", args: "--story-id <STORY-ID> --head feat/story-<STORY-ID> --target-branch <targetBranch> --auto-merge <strategy> --epic-id <EPIC-ID>")

Without --auto-approve-pr, task PRs are the unit of delivery — no story PR. Non-zero exit → PR_CREATE_FAILED. Fallback G1-G7 in references/full-protocol.md §4.

Skill(skill: "x-internal-verify-phase-gates", model: "haiku", args: "--mode post --skill x-implement-story --phase Phase-2-Execute")

TaskUpdate(id: phase2TaskId, status: "completed")

<!-- TELEMETRY: phase.end -->

Bash command: $CLAUDE_PROJECT_DIR/.claude/hooks/telemetry-phase.sh end x-implement-story Phase-2-Implement ok

Phase 2 completed. All tasks executed. Proceeding to Phase 3 (Verify & Report)...

Phase 3 — Verify, Report & Cleanup

<!-- TELEMETRY: phase.start -->

Bash command: $CLAUDE_PROJECT_DIR/.claude/hooks/telemetry-phase.sh start x-implement-story Phase-3-Verify

Skill(skill: "x-internal-verify-phase-gates", model: "haiku", args: "--mode pre --skill x-implement-story --phase Phase-3-Verify")

Open phase tracker (close with TaskUpdate(id: phase3TaskId, status: "completed") at FINAL gate):

TaskCreate(subject: "{STORY_ID} › Phase 3 - Verify", activeForm: "Running verify gate and reviews")

Sub-task trackers (open in Batch A — one per sub-step 3.Q–3.5 — before Skip verification): emit 13 TaskCreate in ONE message (one per Quality-regression / Quality-perf / Quality-mutation / Quality-contract / Quality-dep-policy / Doc generate / Doc validate / Verify gate / Specialist reviews / Tech lead review / Report / Status finalize / Worktree cleanup). Store IDs: p3Tasks = {qualityRegression, qualityPerf, qualityMutation, qualityContract, qualityDepPolicy, docGenerate, docValidate, verify, specialist, techLead, report, status, cleanup}.

The canonical signal is CLAUDE_RECOVERY_MODE=1 — set automatically by x-internal-resume-story when staleWarnings != []. The PreToolUse hook enforce-no-bypass-flags.sh (EPIC-0059, Rule 45) then permits the flags below with a WARNING; skips remain visible in telemetry as phase.end status=skipped. Operator-controlled sessions only — never in automated calls. CLAUDE_RECOVERY_MODE=1 is the ONLY accepted bypass variable; CLAUDE_SKIP_AUDIT=1 / CLAUDE_NO_ENFORCE=1 do NOT bypass (RULE-059-07).

| Flag | Skips | | :--- | :--- | | --skip-verification | Phase 3 (x-internal-verify-story) | | --skip-review | Step 3.2 (x-review-codebase + x-review-pr) | | --skip-quality | Step 3.Q (x-execute-performance-tests + x-execute-mutation-tests + x-execute-contract-tests + x-validate-dependency-policy) — Recovery or hotfix/ only* | | --skip-doc | Step 3.0 (x-generate-docs + x-validate-docs) — Recovery or hotfix/ only (Rule 27 Exception 2)* | | --skip-smoke | Smoke gate inside verify | | --no-ci-watch | CI-watch step in Phase 2 |

Backward Compatibility (RULE-008) + Idempotency (RULE-002)

All new EPIC-0049 flags absent → targetBranch=develop, autoMerge=none, epicId auto-derived — identical to EPIC-0048. --auto-merge without --target-branch → ARGS_INVALID (mutex). Idempotent: story load read-only, artifacts regen only on staleness, task dispatch short-circuits merged PRs, status mutations flock-protected, story PR re-run returns existing {prUrl, prNumber}.

Full Protocol

Minimum viable orchestrator contract above. Complete Phase 0.3 worktree-mode decision table, Phase 1 parallelism matrix, Phase 2 fallback G1-G7 (no test plan / no formal tasks), Phase 3 verify-gate schemas + specialist-review prompt templates + TL-review NO-GO cycle protocol, resume workflow detail, retry/backoff/circuit-breaker schedule, and the SubagentResult error shape all live in references/full-protocol.md per ADR-0012.
