Recipe Fullstack Build

Orchestrator Definition

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

Required Reference

MANDATORY: Read references/monorepo-flow.md from subagents-orchestration-guide skill BEFORE proceeding. Follow the Extended Task Cycle and Agent Routing defined there.

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. Route agents by task filename pattern (see monorepo-flow.md reference):
   • *-backend-task-* → task-executor + quality-fixer
   • *-frontend-task-* → task-executor-frontend + quality-fixer-frontend
3. Follow the 4-step task cycle exactly: executor → escalation check → quality-fixer → commit
4. Enter autonomous mode when user provides execution instruction with existing task files — this IS the batch approval
5. Scope: Complete when all tasks are committed or escalation occurs

CRITICAL: Run layer-appropriate quality-fixer(s) before every commit.

Work plan: $ARGUMENTS

Pre-execution Prerequisites

Implementation Readiness Check

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

1. List task files in docs/plans/tasks/ matching the layer-aware patterns {plan-name}-backend-task-*.md and {plan-name}-frontend-task-*.md only. Single-layer tasks ({plan-name}-task-*.md) are excluded here so a stale single-layer 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 -backend-task- or -frontend-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/

Read the work plan header and find the line Implementation Readiness: <status>. Apply this rule:

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 the Implementation Readiness Check:

1. List task files in docs/plans/tasks/ matching the layer-aware patterns {plan-name}-backend-task-*.md and {plan-name}-frontend-task-*.md for the {plan-name} resolved by the readiness check. Single-layer 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-fullstack: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. Use layer-aware naming: {plan}-backend-task-{n}.md, {plan}-frontend-task-{n}.md based on Target files paths."

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.

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 (Filename-Pattern-Based)

MANDATORY: For each task in the Consumed Task Set, route agents by task filename pattern from monorepo-flow.md reference.

Agent Routing Table

Task Execution (4-Step Cycle)

For EACH task, YOU MUST:

1. Register tasks using TaskCreate: Register work steps. Always include first task "Map preloaded skills to applicable concrete rules" and final task "Verify the mapped rules before final JSON"
2. Agent tool (subagent_type per routing table) → Pass task file path in prompt, receive structured response
3. CHECK executor response:
   • status: "escalation_needed" or "blocked" → STOP and escalate to user
   • requiresTestReview is true → Execute integration-test-reviewer
     • needs_revision → Return to step 2 with requiredFixes
     • approved → Proceed to step 4
   • readyForQualityCheck: true → Proceed to step 4
4. INVOKE quality-fixer: Execute all quality checks and fixes (layer-appropriate per routing table). Always pass the current task file path as task_file
5. CHECK quality-fixer response:
   • stub_detected → Return to step 2 with incompleteImplementations[] details
   • blocked → STOP and escalate to user
   • approved → Proceed to step 6
6. COMMIT on approval: Execute git commit

CRITICAL: Parse every sub-agent response for status fields. Execute the matching branch in the 4-step cycle. Proceed to next task only after layer-appropriate 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)

After all task cycles finish, run verification agents in parallel before the completion report:

1. Invoke both in parallel using Agent tool:

   • code-verifier (subagent_type: "dev-workflows-fullstack:code-verifier") → invoke once per Design Doc (doc_type: design-doc, single document_path, code_paths: implementation file list from git diff --name-only main...HEAD)
   • security-reviewer (subagent_type: "dev-workflows-fullstack:security-reviewer") → Design Doc path(s), implementation file list

2. Consolidate results — check pass/fail for each:

   • code-verifier: pass when status is consistent or mostly_consistent. fail when needs_review or inconsistent. Collect discrepancies with status drift, conflict, or gap
   • security-reviewer: pass when status is approved or approved_with_notes. fail when needs_revision. blocked → Escalate to user
   • Present unified verification report to user

3. Fix cycle (when any verifier failed):

   • Consolidate all actionable findings into a single task file
   • Execute layer-appropriate task-executor with consolidated fixes → quality-fixer
   • Re-run only the failed verifiers (by the criteria in step 2)
   • Repeat until all pass or blocked → Escalate to user

4. All passed → Proceed to Final Cleanup

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, including backend/frontend counts
• Quality check result
• Commit count
• Cleanup result
• Escalation or blocking summary, if any
