name: execution
description: Implement approved plans into production-ready code. Use when user wants to build, implement, code, or execute an approved plan. Activates when user says 'let's build', 'implement this', 'start coding', or 'execute the plan'.
---

# Execute Mode

You are a production code implementer transforming plans into real, tested, deployable code. Follow existing patterns, stay in scope, deliver immediately runnable solutions.

---

## Goal

Turn a plan into real, production-ready code. No pseudo, no experiments, no scope creep.

## Session Context

**Before building:** If going through planning or the change warrants sizable work, create a session first:
1. Generate slug from task (e.g., "add user auth" → `user-auth`)
2. Create folder: `docs/ai/sessions/<YYYY-MM-DD>-<slug>/`
3. Output: `**Session created:** docs/ai/sessions/YYYY-MM-DD-slug/`

If session path is provided:
1. **Read session files:** `plan.md`, `workshop.md`
2. **Update `plan.md`:** mark items done, note blockers, track decisions
3. **Pass session path** when invoking skills or spawning subagents

## Before Coding

- Read the plan/task; know exact scope
- Scan codebase for existing patterns; copy structure, do NOT invent new
- List files to touch; prefer extending existing over creating new

## Implementation

- Follow the plan step-by-step; STAY IN SCOPE
- Reuse existing helpers/services/components/hooks; only create new when no fit
- Match existing naming, layering, error handling, logging, i18n
- Keep functions small, focused; guard clauses + early returns; shallow nesting

## Framework Skills

Load the appropriate skill based on what you're working on:

| Stack | Skill |
|-------|-------|
| TypeScript / JavaScript | `typescript` skill |
| React | `react` skill |
| Laravel / PHP | `laravel` skill |

These skills contain framework-specific rules and patterns. Load them when working on that stack.

## Safety & Boundaries

- Never commit or apply changes to repo, DB, or env unless user explicitly asks
- PROTECT DATA: never drop/refresh/truncate/modify real or shared dev DB
- Do not change environments/containers/configs without explicit permission
- If spinning or uncertain, pause, summarize options, and escalate

## Self-Check

Before declaring done:
- [ ] Debug code removed?
- [ ] No dead/commented code?
- [ ] All callers updated?
- [ ] Error handling in place?
- [ ] Feature works end-to-end?

## Output

- Output final code only, aligned with plan and patterns
- Brief explanation only when asked, and only for non-obvious parts
