description	[Implementation] Plan parallel phases & execute with fullstack-developer agents Use when this capability is needed.

[IMPORTANT] Use TaskCreate to break ALL work into small tasks BEFORE starting — including tasks for each file read. This prevents context loss from long files. For simple tasks, AI MUST ATTENTION ask user whether to skip.

Understand Code First — HARD-GATE: Do NOT write, plan, or fix until you READ existing code.

1. Search 3+ similar patterns (grep/glob) — cite file:line evidence
2. Read existing files in target area — understand structure, base classes, conventions
3. Run python .claude/scripts/code_graph trace <file> --direction both --json when .code-graph/graph.db exists
4. Map dependencies via connections or callers_of — know what depends on your target
5. Write investigation to .ai/workspace/analysis/ for non-trivial tasks (3+ files)
6. Re-read analysis file before implementing — never work from memory alone
7. NEVER invent new patterns when existing ones work — match exactly or document deviation

BLOCKED until: - [ ] Read target files - [ ] Grep 3+ patterns - [ ] Graph trace (if graph.db exists) - [ ] Assumptions verified with evidence

• docs/project-reference/domain-entities-reference.md — Domain entity catalog, relationships, cross-service sync (read when task involves business entities/models) (content auto-injected by hook — check for [Injected: ...] header before reading)
• docs/test-specs/ — Test specifications by module (read existing TCs; generate/update test specs via /tdd-spec after implementation)

Plan Quality — Every plan phase MUST ATTENTION include test specifications.

1. Add ## Test Specifications section with TC-{FEAT}-{NNN} IDs to every phase file
2. Map every functional requirement to ≥1 TC (or explicit TBD with rationale)
3. TC IDs follow TC-{FEATURE}-{NNN} format — reference by ID, never embed full content
4. Before any new workflow step: call TaskList and re-read the phase file
5. On context compaction: call TaskList FIRST — never create duplicate tasks
6. Verify TC satisfaction per phase before marking complete (evidence must be file:line, not TBD)

Mode: TDD-first → reference existing TCs with Evidence: TBD. Implement-first → use TBD → /tdd-spec fills after.

Rationalization Prevention — AI skips steps via these evasions. Recognize and reject:

Evasion	Rebuttal
"Too simple for a plan"	Simple + wrong assumptions = wasted time. Plan anyway.
"I'll test after"	RED before GREEN. Write/verify test first.
"Already searched"	Show grep evidence with file:line. No proof = no search.
"Just do it"	Still need TaskCreate. Skip depth, never skip tracking.
"Just a small fix"	Small fix in wrong location cascades. Verify file:line first.
"Code is self-explanatory"	Future readers need evidence trail. Document anyway.
"Combine steps to save time"	Combined steps dilute focus. Each step has distinct purpose.

Red Flag Stop Conditions — STOP and escalate to user via AskUserQuestion when:

1. Confidence drops below 60% on any critical decision
2. Changes would affect >20 files (blast radius too large)
3. Cross-service boundary is being crossed
4. Security-sensitive code (auth, crypto, PII handling)
5. Breaking change detected (interface, API contract, DB schema)
6. Test coverage would decrease after changes
7. Approach requires technology/pattern not in the project

NEVER proceed past a red flag without explicit user approval.

Skill Variant: Variant of /cook — autonomous parallel execution with fullstack-developer subagents.

Quick Summary

Goal: Plan parallel-executable phases and dispatch to fullstack-developer subagents for concurrent implementation.

Workflow:

1. Plan — Create plan with parallel-executable phases (strict file ownership)
2. Dispatch — Launch fullstack-developer subagents per phase
3. Merge — Integrate results and verify

Key Rules:

• Each subagent owns specific files; no cross-boundary edits
• Autonomous mode: no user confirmation between phases
• Break work into todo tasks; add final self-review task

Ultrathink parallel to implement: $ARGUMENTS

IMPORTANT: Activate needed skills. Ensure token efficiency. Sacrifice grammar for concision.

Be skeptical. Apply critical thinking, sequential thinking. Every claim needs traced proof, confidence percentages (Idea should be more than 80%).

Workflow

1. Research (Optional)

• Use max 2 researcher agents in parallel if tasks complex
• Use /scout-ext to search codebase
• Keep reports ≤150 lines
• External Memory: Write research to .ai/workspace/analysis/{task-name}.analysis.md. Re-read before parallel execution.

2. Parallel Planning

• Trigger /plan-parallel <detailed-instruction>
• Wait for plan with dependency graph, execution strategy, file ownership matrix

3. Parallel Implementation

• Read plan.md for dependency graph
• Launch multiple fullstack-developer agents in PARALLEL for concurrent phases
  • Example: "Phases 1-3 parallel" → launch 3 agents simultaneously
  • Pass phase file path: {plan-dir}/phase-XX-*.md
  • Include environment info
• Wait for all parallel phases complete before dependent phases
• Sequential phases: launch one agent at a time

4. Testing

• Use tester subagent for full test suite
• NO fake data/mocks/cheats
• If fail: use debugger, fix, repeat

5. Code Review

• Use code-reviewer for all changes
• If critical issues: fix, retest

6. Project Management & Docs

• If approved: use project-manager + docs-manager in parallel
• Update plan files, docs, roadmap
• If rejected: fix and repeat

7. Final Report

• Summary of all parallel phases
• Guide to get started
• Ask to commit (use git-manager if yes)

Example: Phases 1-3 parallel → Launch 3 fullstack-developer agents → Wait → Phase 4 sequential

Next Steps (Standalone: MUST ATTENTION ask user via AskUserQuestion. Skip if inside workflow.)

MANDATORY IMPORTANT MUST ATTENTION — NO EXCEPTIONS: If this skill was called outside a workflow, you MUST ATTENTION use AskUserQuestion to present these options. Do NOT skip because the task seems "simple" or "obvious" — the user decides:

• "Proceed with full workflow (Recommended)" — I'll detect the best workflow to continue from here (feature implemented). This ensures review, testing, and docs steps aren't skipped.
• "/code-simplifier" — Simplify and clean up implementation
• "/workflow-review-changes" — Review changes before commit
• "Skip, continue manually" — user decides

If already inside a workflow, skip — the workflow handles sequencing.

Closing Reminders

• MANDATORY IMPORTANT MUST ATTENTION break work into small todo tasks using TaskCreate BEFORE starting
• MANDATORY IMPORTANT MUST ATTENTION search codebase for 3+ similar patterns before creating new code
• MANDATORY IMPORTANT MUST ATTENTION cite file:line evidence for every claim (confidence >80% to act)
• MANDATORY IMPORTANT MUST ATTENTION add a final review todo task to verify work quality
• MANDATORY IMPORTANT MUST ATTENTION validate decisions with user via AskUserQuestion — never auto-decide
• MANDATORY IMPORTANT MUST ATTENTION search 3+ existing patterns and read code BEFORE any modification. Run graph trace when graph.db exists.
• MANDATORY IMPORTANT MUST ATTENTION include ## Test Specifications with TC IDs per phase. Call TaskList before creating new tasks.
• MANDATORY IMPORTANT MUST ATTENTION follow ALL steps regardless of perceived simplicity. "Too simple to plan" is an evasion, not a reason.
• MANDATORY IMPORTANT MUST ATTENTION STOP after 3 failed fix attempts. Report all attempts, ask user before continuing.
