Treido Orchestrator (Single Writer)

This skill coordinates a predictable workflow:

• Phase 1 (Parallel): specialist auditors (read-only) return structured payloads
• Phase 2 (Single-writer): merge audits + write a prioritized plan in TASKS.md
• Phase 3 (Single-writer): implement tasks in 1–3 file batches
• Phase 4 (Single-writer): run verification gates
• Phase 5 (Single-writer): run the smallest relevant tests

Non-Negotiables

• Single-writer rule:
  • Auditors + verifier are read-only (no patches, no TASKS.md edits).
  • Orchestrator is the sole writer for audit/* and TASKS.md.
  • Code changes happen in the implementer lane (still one writer per batch).
• Small batches: execute as 1–3 file rounds; run gates after each round.
• Rails first: no secrets/PII in logs, next-intl for user strings, Tailwind v4 tokens only, cached-server rules, no scope creep.

Bundle Matrix (Intent → Auditors)

Preferred auditor skill names (new system):

• treido-audit-nextjs
• treido-audit-tw4
• treido-audit-shadcn
• treido-audit-supabase
• treido-audit-typescript

Fallbacks (if a new auditor skill doesn’t exist yet):

• Next.js: nextjs-structure (or treido-frontend for boundary scans)
• TW4: treido-tailwind-v4
• SHADCN: treido-shadcn
• Supabase: treido-supabase-mcp
• TypeScript: treido-audit (TS-focused scan) + pnpm -s typecheck

Phase 1 — Specialist Audits (Parallel, Read-only)

1. Select a bundle from the matrix (or accept an explicit override like ORCH:UI, ORCH:FULL).
2. Spawn auditors in parallel. Each auditor must return only the structured payload contract:
   • Contract: .codex/skills/treido-orchestrator/references/audit-payload.md
3. Validate the payloads are mergeable (each starts with ## <AUDITOR> and includes the required sections).

Auditor Prompt Template (copy/paste)

Send each auditor this message (customize scope/context):

You are an audit-only specialist. Read-only: do not patch files, do not edit TASKS.md.

Goal/context: <1–2 sentences>
Scope hints: <routes/files if known>

Return ONLY a Markdown section that follows:
.codex/skills/treido-orchestrator/references/audit-payload.md

No preamble. Start with `## <AUDITOR_NAME>`.

Phase 1.5 — Merge Audits (Single Writer)

1. Create a shared audit artifact under audit/:
   • audit/YYYY-MM-DD_<short-context>.md
2. Merge auditor sections verbatim (no rewrites beyond formatting), ordered by bundle.
3. Ensure no secrets/PII are written into audit artifacts.

Phase 2 — Plan (Write TASKS.md)

1. Convert findings into tasks with clear priority and acceptance criteria.
2. Keep tasks small (≤ 1 day) and executable in 1–3 file rounds.
3. Prefer these owners (new system), otherwise use existing owners:
   • treido-impl-frontend (fallback: treido-frontend)
   • treido-impl-backend (fallback: treido-backend)
   • treido-verify (fallback: treido-audit)
4. Respect TASKS.md “Ready ≤15” rules.

Task block (recommended):

### Priority 1 (Critical)
- [ ] <ID>: <task summary>
  - Owner: <skill>
  - Verify: `<commands>`
  - Files: <paths>

Phase 3 — Execute (Single Writer)

1. Pick the smallest set of Priority 1 tasks that fit into a 1–3 file batch.
2. Implement using the owner lane conventions (frontend vs backend).
3. Avoid unrelated refactors; defer follow-ups into TASKS.md.

Phase 4 — Verify / QA

Always:

pnpm -s typecheck
pnpm -s lint
pnpm -s styles:gate

Phase 5 — Tests (Risk-based)

• UI-only: consider pnpm -s test:unit (and/or Storybook spot-check if used)
• Auth/payments/checkout/webhooks: REUSE_EXISTING_SERVER=true pnpm -s test:e2e:smoke
• Database/RLS: run Supabase advisors + regenerate types (via MCP lane) when applicable
