React Developer

STOP - Read before ANY tool call

1. Read E:/Source/Repos/agent-dev-toolkit/scripts/validation/fixtures/install-root/rules/guardrails.md
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

Trigger

Use when user asks for /react-developer, react fix, or a small isolated React implementation.

Outcome

Working React components and tests in the target workspace, validated with tests/build, with optional handoff to /commit.

When to escalate to SDD

Recommend sdd-spec -> sdd-plan -> sdd-develop if two or more apply: 3+ layers touched, new API contracts, cross-repo impact, 10+ files, or existing approved PLAN.

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.

Lazy-load references

Do not preload unrelated guideline trees.

Process

Step -1b - Caveman Mode (Full cap)

1. Read E:/Source/Repos/agent-dev-toolkit/scripts/validation/fixtures/install-root/sdd/preferences.json (create { "caveman_mode": false, "caveman_level": "full" } if missing).
2. If caveman_mode is false: continue without compression.
3. If true: load E:/Source/Repos/agent-dev-toolkit/scripts/validation/fixtures/install-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.
4. Honor caveman on|off|status|lite|full|ultra (and stop caveman / normal mode) during the session.
5. Auto-Clarity + never-compress gates/drafts/paths per CAVEMAN.md.

0. Workspace

Confirm React project (package.json with React). If blip-ds is present, load Blip guidelines from lazy-load table. Read README.md, summarize acceptance.

1. Guidelines

Load only required React/frontend guidelines for this task.

2. Branch

Use feature/<slug> or feat/<id>. Never commit on main/master/develop.

3. Micro-plan

Define 3-7 concrete tasks; checkpoint context at >= 40%.

4. Implement

Functional components, hooks, clean React architecture. Match existing patterns.

5. Tests

Jest / React Testing Library for changed behavior.

6. Validate

npm test
npm run build

(or project-equivalent scripts)

7. Handoff

Offer /commit. Do not commit automatically.

Must not

• Auto-commit or auto-PR
• Leave AI traces in code or identifiers
• Use obsolete corporate pipeline docs

Handoff
