name: react-developer

description: Implement or fix small-to-medium React features without full SDD (hooks, TSX, RTL). Use for isolated React work or when invoking /react-developer.

## STOP - Read before ANY tool call

1. Read `{{GUARDRAILS_PATH}}`

2. Read `_shared/sdd-artifacts/SESSION.md`; load session-state for `$Cwd`

3. If the relevant gate is not approved: **STOP** - ask user **(pt-BR)** - do **NOT** Write/Shell

4. SDD/develop skills: after **ONE** step/task, **STOP** session - handoff only

5. This skill body is **English**; user-facing prompts may be **(pt-BR)**

### Step -1 - Gate check (report in chat before continuing)

```

Gate check:

[ ] guardrails.mdc read

[ ] SESSION.md read; session-state loaded

[ ] User confirmed current action (sim)

-> If any unchecked: STOP

```

+ # Skill: react-developer

## Trigger

Invoke when the user asks for: `/react-developer`, `react fix`, or **small** isolated React (web) work that does not need a full PRD/PLAN cycle.

## Outcome

Working React components and tests in the target workspace, validated with tests/build, on a valid feature branch, with optional `/commit` handoff. Does not replace SDD for multi-step or cross-repo features.

- ## When to prefer SDD instead

- Recommend `/sdd-spec` -> `sdd-plan` -> `sdd-develop` if **two or more** apply:

- | Signal | Indicator |

- |--------|-----------|

- | Layers | 3+ layers (UI, state, API client, shared packages) across many modules |

- | API contracts | New or altered HTTP/API contracts shared across apps |

- | Repos | Frontend and another repo or service |

- | Integrations | New auth, messaging, or external SDKs |

- | Size | 10+ files or estimated 4+ hours |

- | PLAN exists | User already has an approved PLAN - use `sdd-develop` |

- ## DESIGN-BRIEF acceptance

- If `docs/DESIGN-BRIEF.md` or `docs/design/DESIGN-BRIEF.md` exists, treat it as the acceptance source. Map sections to React/TSX; do **not** reinterpret visual decisions. Implement **one session scope** from section 10 only.

- If the task is net-new UI without a brief, recommend `/impeccable shape` in a **new session** before implementing.

+ | Reference index (routing only) | `{{TOOLKIT_ROOT}}/skills/react-developer/reference.md` |

+ | Process step detail (lazy) | `{{TOOLKIT_ROOT}}/skills/react-developer/references/<section>.md` |

Do **not** preload unrelated guideline trees. Do not redesign `react-guidelines/` in this skill — load existing pack rows only. For **mobile** React Native / Expo, route to `/react-native-developer` instead.

- **Never by default:** do not preload other stack guideline packs or full frontend trees. Load only rows needed for the current task.

+ **Never by default:** do not preload all `references/*.md`. do not preload other stack guideline packs or full frontend trees. Load only rows needed for the current task. Do not dump full stack guideline packs or memory-bank. Load **one** section per Process step (`SKILL-REFERENCE-RETRIEVAL.md`).

+ ## Reference routing

+ | Situation | Path |

+ |-----------|------|

+ | Scope / SDD escalation / design brief | `references/scope.md` |

+ | Implement flow | `references/execute-flow.md` |

+ | Must not (full) | `references/must-not.md` |

## Process

+ Read `references/<section>.md` for procedural detail — **not** full `reference.md`.

### Step -1b - Caveman Mode (Full cap)

1. Read `{{SDD_ROOT}}/preferences.json` (create `{ "caveman_mode": false, "caveman_level": "full" }` if missing).

2. If `caveman_mode` is false: continue without compression.

3. If true: load `{{TOOLKIT_ROOT}}/skills/_shared/caveman/CAVEMAN.md`; apply **Full** participation cap + prefs `caveman_level` (Lite skills never escalate); show once: `[Caveman] Modo ativo (respostas compactas, level={effective}). Digite caveman off para desativar.`

5. Auto-Clarity + never-compress gates/drafts/paths per `CAVEMAN.md`.

- ### Subagent-first (before implement)

- Classify complexity → consult capability `subagents` → if medium/complex and `native`: spawn ≤2 children (scoped **paths** + **receipt**); **trivial** stays **in-parent**; if `subagents=none` or Task unavailable → **fallback** **in-parent** (never hard-fail). Load `SPAWN.md` + `subagent-first.md`; do not paste guidelines into child prompts.

- ### 0. Workspace

- Confirm React web project (`package.json` with React; not RN-only). If `blip-ds` is present, load Blip guidelines from lazy-load table. Follow `step-0-context.md`. Summarize acceptance.

- ### 1. Guidelines (step 0.5)

- Follow `step-0.5-review-guidelines.md`: load only required React/frontend guideline files for this task.

- ### 2. Branch (step 3)

- Baseline from user or repo default. Create/checkout `feature/<slug>` or `feat/<id>` — never commit on `main` / `master` / `develop`.

- ### 3. Plan micro-steps

- List 3-7 concrete tasks; checkpoint per `context-management.mdc` (>= 40% -> pause, offer `/commit`).

- ### 4. Implement

- Functional components, hooks, clean React architecture. Match existing patterns. Apply `react-guidelines/` while writing — do not paste full bodies into chat.

- ### 5. Tests

- Jest / React Testing Library for changed behavior.

- ### 6. Build and test

- ```bash

- npm test

- npm run build

- ```

- (or project-equivalent scripts)

- ### 7. Pre-commit (step 3.5) and handoff

+ ### 0. Scope

+ Follow `references/scope.md` (SDD escalation, design brief / host detection when present).

- Run `step-3.5-precommit-validation.md` when appropriate. Offer `/commit` — do not commit automatically. Before push/PR, run `step-7-checklist.md`.

+ ### 1. Execute

+ Follow `references/execute-flow.md` (subagent-first, workspace → guidelines → branch → implement → tests → handoff).

## Must not

- - Paste guideline packs into child prompts (pass scoped **paths** + require **receipt** only)

- - Spawn children for **trivial** work (keep **in-parent**)

- - Hard-fail when capability `subagents` is `none` or Task is unavailable (use **fallback** **in-parent**)

- - Redesign or rewrite the `react-guidelines/` pack in-session

- - Auto-commit or auto-PR

- - Leave AI traces in code or identifiers

- - Use obsolete corporate pipeline docs

+ Enforce the full list in `references/must-not.md`. Critical: no guideline dumps into children; no auto-commit; lazy-load stack guidelines only — never dump full packs or memory-bank.

## Handoff

| Situation | Next |

|-----------|------|

| Commit | `/commit` |

| Review | `/code-review` |

| Scope grew | `/sdd-spec` -> `sdd-plan` -> `sdd-develop` |

| Missing design brief | `/impeccable shape` (new session) |

| Mobile / Expo | `/react-native-developer` |
