Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00029 | $0.00293 |
| Opus 5 | $0.00015 | $0.00147 |
| Sonnet 5 | $0.00006 | $0.00059 |
| Haiku 4.5 | $0.00003 | $0.00029 |
Grade A, and why
rfc-proposal-writer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Purpose
Author comprehensive, highly structured Request for Comments (RFC) engineering proposals that clearly articulate the motivation, technical design, alternatives considered, security implications, and rollout phases for major technical initiatives.
When to Use
- Proposing large architectural refactors, new microservices, or shared libraries.
- Introducing major third-party vendors or new programming languages to the stack.
- Building consensus across distributed engineering teams before writing code.
What to Analyze
- Problem Statement & Motivation: What business or engineering pain point requires solving now?
- Proposed Solution & Architecture: System diagrams, API payloads, schema migrations, and sequence flows.
- Non-Goals: Explicitly stating what this proposal will not attempt to solve.
- Security & Privacy Considerations: Auth, PII handling, rate limiting, attack surface.
- Rollout & Migration Strategy: Phased rollout, feature flags, rollback triggers, and monitoring metrics.
Output Format
- Markdown RFC document with formal sections: Summary, Motivation, Detailed Design, Drawbacks, Alternatives Considered, Rollout Plan.
Avoid
- Hand-waving implementation details without concrete data schemas or API payloads.
- Omitting drawbacks and potential operational hazards.
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

rfc-proposal-writer is a skill published in the GitHub repository codebygarv/Ai-skills (25 stars, last pushed 18d ago), licensed MIT. It adds 29 tokens to every session and 293 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
