Skill v1.0.3

version: "1.0.3" name: recipe-build description: Execute decomposed tasks in autonomous execution mode disable-model-invocation: true

Execute Skill: llm-friendly-context before writing Agent prompts, handoffs, or generated artifacts.

Orchestrator Definition

Core Identity: "I am an orchestrator." (see subagents-orchestration-guide skill)

Execution Protocol:

1. Delegate all work through Agent tool — invoke sub-agents, pass deliverable paths between them, and report results (permitted tools: see subagents-orchestration-guide "Orchestrator's Permitted Tools")
2. Follow the 4-step task cycle exactly: execute → branch on executor result → quality-fix → commit
3. Enter autonomous mode when user provides execution instruction with existing task files — this IS the batch approval
4. Scope: Complete when all tasks are committed or escalation occurs

CRITICAL: Run quality-fixer before every commit.

Work plan: $ARGUMENTS

Pre-execution Prerequisites

Work Plan Resolution

Before any task processing, locate the work plan. Resolution rule:

1. List task files in docs/plans/tasks/ matching the single-layer pattern {plan-name}-task-*.md. Layer-aware fullstack tasks ({plan-name}-backend-task-*.md / {plan-name}-frontend-task-*.md) are excluded here so a stale fullstack run does not redirect this recipe to the wrong work plan
2. From the matched files, also exclude every file matching any of these patterns — they originate from other workflow phases and are not implementation tasks for this run's plan: *-task-prep-*.md (readiness preflight tasks), _overview-*.md (decomposition overview file), *-phase*-completion.md (per-phase completion files), review-fixes-*.md (post-implementation review fixes), integration-tests-*-task-*.md (integration-test add-on scaffolding)
3. For each remaining file, extract the {plan-name} prefix as the segment that appears before -task-
4. When at least one task file matches, the work plan is docs/plans/{plan-name}.md for the prefix that has the most recent task-file mtime; ties broken by the lexicographically last {plan-name}
5. When no task file matches the restricted pattern, the work plan is the most-recent-mtime non-template .md in docs/plans/

Consumed Task Set

Compute the Consumed Task Set for this run — the exact files this recipe owns, executes, and later deletes. Use the same restricted pattern as Work Plan Resolution:

1. List task files in docs/plans/tasks/ matching the single-layer pattern {plan-name}-task-*.md for the {plan-name} resolved by Work Plan Resolution. Layer-aware fullstack tasks are excluded
2. Exclude every file matching: *-task-prep-*.md, _overview-*.md, *-phase*-completion.md, review-fixes-*.md, integration-tests-*-task-*.md (these originate from other workflow phases)

Every subsequent reference to "task files" in this recipe — Task Generation Decision Flow, Task Execution Cycle iteration, and Final Cleanup — uses this set, not the unrestricted docs/plans/tasks/*.md glob.

Task Generation Decision Flow

Analyze the Consumed Task Set and determine the action required:

Task Decomposition Phase (Conditional)

When the Consumed Task Set is empty:

1. User Confirmation

No task files in the Consumed Task Set.
Work plan: docs/plans/[plan-name].md
 
Generate tasks from the work plan? (y/n):

2. Task Decomposition (if approved)

Invoke task-decomposer using Agent tool:

• subagent_type: "dev-workflows:task-decomposer"
• description: "Decompose work plan"
• prompt: "Read work plan at docs/plans/[plan-name].md and decompose into atomic tasks. Output: Individual task files in docs/plans/tasks/. Granularity: 1 task = 1 commit = independently executable"

3. Verify Generation

Recompute the Consumed Task Set using the same restricted pattern from the Consumed Task Set section above. Confirm it is now non-empty. If it is still empty, escalate to the user — task-decomposer either failed silently or produced files that don't match the expected pattern.

Flow: Task generation → Consumed Task Set recompute → Autonomous execution (in this order)

Pre-execution Checklist

• [ ] Confirmed Consumed Task Set is non-empty (computed in the Consumed Task Set section above)
• [ ] Identified task execution order within the Consumed Task Set (dependencies)
• [ ] Environment check: Can I execute per-task commit cycle?
• If commit capability unavailable → Escalate before autonomous mode
• Other environments (tests, quality tools) → Subagents will escalate

Task Execution Cycle (4-Step Cycle)

MANDATORY EXECUTION CYCLE: execute → branch on executor result → quality-fix → commit

Before the loop, register "Execute consumed task set", "Run post-implementation verification", "Clean up consumed task files", and "Report completion" once with TaskCreate; mark and advance the active phase with TaskUpdate.

For EACH task in the Consumed Task Set, YOU MUST:

1. EXECUTE: invoke Agent tool (subagent_type: "dev-workflows:task-executor") → Record the current HEAD as diffBase, pass the task file path in the prompt, and receive the structured response
2. BRANCH ON EXECUTOR RESULT:

• status: "escalation_needed" or "blocked" → STOP and escalate to user
• requiresTestReview is true → Invoke integration-test-reviewer with diffBase, changed integration/E2E paths, taskFile, prompt-only claims, and mutationEvidence
• needs_revision → Return to step 1 with requiredFixes
• approved → Proceed to step 3
• blocked → STOP and escalate to user
• readyForQualityCheck: true → Proceed to step 3

1. QUALITY-FIX: Invoke quality-fixer with task_file, upstream mutationEvidence, and qualityCommand when available (caller first, otherwise current task)

• stub_detected → Return to step 1 with incompleteImplementations[] details
• blocked → STOP and escalate to user
• approved → Proceed to step 4

1. COMMIT: Execute git commit after quality-fixer returns approved

CRITICAL: Parse every sub-agent response for status fields. Execute the matching branch in the 4-step cycle. Proceed to next task only after quality-fixer returns approved.

Scope Boundary for Subagents

Append the following block to every subagent prompt invoked from this recipe:

Scope boundary for subagents:
Operate within the task scope and referenced files in the prompt.
Use loaded skills to execute that scope.
Escalate when the required fix or investigation falls outside that scope.

Verify task files exist per Pre-execution Checklist, then enter autonomous execution mode. When requirement changes are detected during execution, escalate to the user with the change summary before continuing.

Post-Implementation Verification (After All Tasks Complete)

Resolve the Work Plan's readable Design Doc, or the Work Plan itself when no Design Doc exists; missing input blocks verification.

Emit these Agent calls in one assistant message, then await both:

• code-verifier (subagent_type: "dev-workflows:code-verifier") → resolved doc_type, document_path, and code_paths from git diff --name-only main...HEAD
• security-reviewer (subagent_type: "dev-workflows:security-reviewer") → the same typed governingDocuments and implementationFiles

Apply subagents-orchestration-guide's Post-Implementation Verification pass/fail and fix/re-run rules. Present the unified report; proceed to Final Cleanup after both pass.

Final Cleanup

Before the completion report, delete the implementation task files this recipe consumed. Their work is committed; docs/plans/ is ephemeral working state and is not retained between recipe runs:

• Delete every file in the Consumed Task Set
• Delete every file matching docs/plans/tasks/{plan-name}-phase*-completion.md (the per-phase completion files generated by task-decomposer for this {plan-name})
• Delete the corresponding docs/plans/tasks/_overview-{plan-name}.md if present
• Preserve the work plan itself (docs/plans/{plan-name}.md) — the user decides whether to delete it after final review

If task files cannot be deleted (filesystem error), report the failure but do not block the completion report.

Completion Report Contract

Final report must include:

• Task decomposition status
• Implemented task count
• Quality check result
• Commit count
• Cleanup result
• Escalation or blocking summary, if any
