Créer et valider des RFC

---

name: write-rfc description: Scaffold and validate ArenaQuest RFCs against the house standard so every proposal in docs/product/RFCs follows the same structure (numbered file, metadata header, canonical sections, README index row). Triggers: write rfc, create rfc, new rfc, draft rfc, scaffold rfc, rfc template, rfc standard, validate rfc, check rfc

ArenaQuest keeps formal proposals in docs/product/RFCs/ as NNNN-<kebab-title>.md, indexed by docs/product/RFCs/README.md. This skill enforces that standard with two dependency-free Node scripts:

• new-rfc.mjs — scaffolds the next-numbered RFC from template.md and appends its index row to the README.
• check-rfc.mjs — validates one or all RFCs against the standard; non-zero exit on a hard violation, so it drops into a pre-commit hook or CI.

Paths below are relative to the repo root (docs/product/RFCs, the scripts under .claude/skills/write-rfc/). Run them from the repo root.

The .claude/skills/ directory is a symlink to .agents/skills/. It resolves fine for the Node runtime (Linux). The Windows \\wsl.localhost bridge can't traverse the symlink — if a tool errors with ENOTDIR / Input/output error on .claude/skills/..., use the real path .agents/skills/write-rfc/... instead. Both point at the same files.

The standard

Every RFC has, in this order:

1. Filename NNNN-<kebab-title>.md — 4-digit zero-padded, sequential.
2. Title # RFC NNNN: <Title> — number matches the filename.
3. Metadata block (bold fields): **Status:**, **Author:**, **Date:** (PT Autor: / Data: accepted), plus optional **Revised:** and an **Affected:** file list. Then a --- divider.
4. Sections (##): Summary, Motivation, Goals & Non-Goals, Current State (omit if greenfield), Proposed Design, Alternatives Considered, Implementation Plan, Tradeoffs & Risks, Success Criteria, Open/Resolved Decisions, References. See template.md for the prose guidance per section.
5. README index row in docs/product/RFCs/README.md.

Status lifecycle: Draft → Proposed → Approved → In Progress → Implemented/Done/Completed; or Rejected / Superseded.

Create a new RFC (agent path)

node .claude/skills/write-rfc/new-rfc.mjs "Title of the proposal" --author raphaelsilva

Prints the created path (e.g. docs/product/RFCs/0007-title-of-the-proposal.md) and adds the README index row. Options: --status (default Draft), --date YYYY-MM-DD (default today), --author (default git config user.name), --dir (default docs/product/RFCs). Then fill in each ## section — the template body explains what belongs in each.

Validate (agent path)

Check every RFC in the directory:

node .claude/skills/write-rfc/check-rfc.mjs

Check a single file (use this on the RFC you just wrote):

node .claude/skills/write-rfc/check-rfc.mjs docs/product/RFCs/0005-enrollment-exclusions-and-visibility.md

Output: ✓ clean, ⚠ recommended section missing (advisory — exit 0), ✗ hard violation (exit 1). ERROR = wrong filename, missing/mismatched # RFC NNNN title, missing Status/Author/Date metadata, or not linked from the README index. warn = a recommended ## section is absent (older RFCs predate the full skeleton, so these don't block).

Gotchas

• .claude/skills is a symlink (→ .agents/skills). Native file tools reaching it over the Windows bridge throw Input/output error; run scripts through the WSL Node runtime, or edit files via .agents/skills/write-rfc/.
• Exit codes are swallowed by the wsl.exe … bash -c '… ; echo $?' bridge — $? reads as 0 even when Node exited non-zero. To observe the real result use &&/|| evaluated inside WSL: node …/check-rfc.mjs && echo PASS || echo FAIL.
• The standard is advisory for legacy RFCs. 0001 is Portuguese (Autor:/ Data: — accepted) and 0003 embeds its date inside the Status line, so check-rfc.mjs flags 0003 as ✗ missing Date. That is a real, known gap in an existing doc, not a script bug — don't "fix" the validator to hide it.
• Numbering reads the directory, not the README. If a number was skipped or a draft file deleted, the next number follows the highest existing NNNN-*.md, not the index.

Files

• .claude/skills/write-rfc/new-rfc.mjs — scaffolder (Node, stdlib only).
• .claude/skills/write-rfc/check-rfc.mjs — validator (Node, stdlib only).
• .claude/skills/write-rfc/template.md — the canonical section skeleton with per-section prose guidance; new-rfc.mjs fills its {{...}} placeholders.
