description	[Implementation] Start coding & testing an existing plan 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.

Prerequisites: MUST ATTENTION READ before executing:

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/frontend-patterns-reference.md (content auto-injected by hook — check for [Injected: ...] header before reading)
• docs/project-reference/scss-styling-guide.md — Styling/BEM guide (read when task involves frontend/UI)
• docs/project-reference/design-system/README.md — Design system tokens (read when task involves frontend/UI)
• docs/project-reference/domain-entities-reference.md — Domain entity catalog, relationships, cross-service sync (read when task involves business entities/models)

External Memory: For complex or lengthy work (research, analysis, scan, review), write intermediate findings and final results to a report file in plans/reports/ — prevents context loss and serves as deliverable.

Evidence Gate: MANDATORY IMPORTANT MUST ATTENTION — every claim, finding, and recommendation requires file:line proof or traced evidence with confidence percentage (>80% to act, <80% must verify first).

Quick Summary

Goal: Execute an existing implementation plan phase-by-phase with testing, code review, and user approval gates.

Workflow:

1. Plan Detection — Find latest plan or use provided path, select next incomplete phase
2. Analysis & Tasks — Extract tasks from phase file into TaskCreate
3. Implementation — Implement step-by-step, run type checks
4. Testing — Call tester subagent; must reach 100% pass before proceeding
5. Code Review — Call code-reviewer subagent; must reach 0 critical issues
6. User Approval — BLOCKING gate: wait for explicit user approval
7. Finalize — Update status, docs, and auto-commit

Key Rules:

• Tests must be 100% passing (Step 3 gate)
• Critical issues must be 0 (Step 4 gate)
• User must explicitly approve before finalize (Step 5 gate)
• One plan phase per command run

MUST ATTENTION READ CLAUDE.md then THINK HARDER to start working on the following plan:

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

$ARGUMENTS

---

Pre-Implementation Granularity Gate (MANDATORY)

Plan Granularity — Every phase must pass 5-point check before implementation:

1. Lists exact file paths to modify (not generic "implement X")
2. No planning verbs (research, investigate, analyze, determine, figure out)
3. Steps ≤30min each, phase total ≤3h
4. ≤5 files per phase
5. No open decisions or TBDs in approach

Failing phases → create sub-plan. Repeat until ALL leaf phases pass (max depth: 3). Self-question: "Can I start coding RIGHT NOW? If any step needs 'figuring out' → sub-plan it."

If ANY check fails → STOP. Ask user: "Phase needs more detail before implementation. Refine with /plan? [Y/n]" DO NOT implement a phase that contains planning verbs, unnamed files, or unresolved decisions.

---

Step 0: Plan Detection & Phase Selection

If $ARGUMENTS is empty:

1. Find latest plan.md in ./plans
2. Parse plan for phases and status, auto-select next incomplete (prefer IN_PROGRESS or earliest Planned)

If $ARGUMENTS provided: Use that plan and detect which phase to work on.

Output: ✓ Step 0: [Plan Name] - [Phase Name]

---

Workflow Sequence

Rules: Follow steps 1-6 in order. Each step requires output marker ✓ Step N:. Mark each complete in TaskCreate before proceeding. Do not skip steps.

---

Step 1: Analysis & Task Extraction

Read plan file completely. Map dependencies. List ambiguities. Identify required skills and activate from catalog. If the plan references analysis files in .ai/workspace/analysis/, re-read them before implementation.

TaskCreate Initialization:

• Initialize TaskCreate with Step 0: [Plan Name] - [Phase Name] and all steps (1-6)
• Read phase file, look for tasks/steps/phases/sections/numbered/bulleted lists
• Convert to TaskCreate tasks with UNIQUE names:
  • Phase Implementation tasks → Step 2.X (Step 2.1, Step 2.2, etc.)
  • Phase Testing tasks → Step 3.X
  • Phase Code Review tasks → Step 4.X

Output: ✓ Step 1: Found [N] tasks across [M] phases - Ambiguities: [list or "none"]

---

Step 2: Implementation

Implement selected plan phase step-by-step following extracted tasks. Mark tasks complete as done. For UI work, call ui-ux-designer subagent. Run type checking and compile to verify.

Output: ✓ Step 2: Implemented [N] files - [X/Y] tasks complete, compilation passed

---

Step 3: Testing

Call tester subagent. If ANY tests fail: STOP, call debugger subagent, fix, re-run. Repeat until 100% pass.

Testing standards: Unit tests may use mocks. Integration tests use test environment. Forbidden: commenting out tests, changing assertions to pass, TODO/FIXME to defer fixes.

Output: ✓ Step 3: Tests [X/X passed] - All requirements met

Validation: If X ≠ total, Step 3 INCOMPLETE - do not proceed.

---

Step 4: Code Review

Call code-reviewer subagent. If critical issues found: STOP, fix, re-run tester, re-run code-reviewer. Repeat until no critical issues.

Output: ✓ Step 4: Code reviewed - [0] critical issues

Validation: If critical issues > 0, Step 4 INCOMPLETE - do not proceed.

---

Step 5: User Approval ⏸ BLOCKING GATE

Present summary (3-5 bullets): what implemented, tests passed, code review outcome.

Ask user explicitly: "Phase implementation complete. All tests pass, code reviewed. Approve changes?"

Stop and wait - do not proceed until user responds.

Output: ✓ Step 5: User approved - Ready to complete

---

Step 6: Finalize

Prerequisites: User approved in Step 5.

1. STATUS UPDATE (PARALLEL):

   • Call project-manager subagent to update plan status
   • Call docs-manager subagent to update documentation

2. ONBOARDING CHECK: Detect onboarding requirements + generate summary.

3. AUTO-COMMIT: Call git-manager subagent. Run only if Steps 1-2 successful + User approved + Tests passed.

Output: ✓ Step 6: Finalize - Status updated - Git committed

---

Critical Enforcement Rules

Step output format: ✓ Step [N]: [Brief status] - [Key metrics]

TaskCreate tracking required: Initialize at Step 0, mark each step complete before next.

Mandatory subagent calls: Step 3: tester | Step 4: code-reviewer | Step 6: project-manager AND docs-manager AND git-manager

Blocking gates:

• Step 3: Tests must be 100% passing
• Step 4: Critical issues must be 0
• Step 5: User must explicitly approve

Do not skip steps. Do not proceed if validation fails. Do not assume approval without user response. One plan phase per command run.

Workflow Recommendation

MANDATORY IMPORTANT MUST ATTENTION — NO EXCEPTIONS: If you are NOT already in a workflow, you MUST ATTENTION use AskUserQuestion to ask the user. Do NOT judge task complexity or decide this is "simple enough to skip" — the user decides whether to use a workflow, not you:

1. Activate refactor workflow (Recommended) — scout → investigate → plan → code → review → sre-review → test → docs
2. Execute /code directly — run this skill standalone

---

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

MANDATORY IMPORTANT MUST ATTENTION — NO EXCEPTIONS after completing this skill, 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 (code implemented). This ensures review, testing, and docs steps aren't skipped.
• "/code-simplifier" — Simplify implementation
• "/workflow-review-changes" — Review changes before commit
• "Skip, continue manually" — user decides

Standalone Review Gate (Non-Workflow Only)

MANDATORY IMPORTANT MUST ATTENTION: If this skill is called outside a workflow (standalone /code), you MUST ATTENTION create a TaskCreate todo task for /review-changes as the last task in your task list. This ensures all changes are reviewed before commit even without a workflow enforcing it.

If already running inside a workflow (e.g., feature, refactor), skip this — the workflow sequence handles /review-changes at the appropriate step.

Closing Reminders

MANDATORY IMPORTANT MUST ATTENTION break work into small todo tasks using TaskCreate BEFORE starting. MANDATORY IMPORTANT MUST ATTENTION validate decisions with user via AskUserQuestion — never auto-decide. MANDATORY IMPORTANT MUST ATTENTION add a final review todo task to verify work quality. MANDATORY IMPORTANT MUST ATTENTION READ the following files before starting:

• IMPORTANT MUST ATTENTION verify all phases pass 5-point granularity check. Failing phases → sub-plan. "Can I start coding RIGHT NOW?"

          <!-- SYNC:understand-code-first:reminder -->
  

• IMPORTANT MUST ATTENTION search 3+ existing patterns and read code BEFORE any modification. Run graph trace when graph.db exists.

• IMPORTANT MUST ATTENTION READ CLAUDE.md before starting
