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)

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

Work Plan Resolution

Before any task processing, locate the work plan. 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/

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 layer-aware patterns {plan-name}-backend-task-*.md and {plan-name}-frontend-task-*.md for the {plan-name} resolved by Work Plan Resolution. 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.
