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.

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 | $0.00010 | $0.00248 |
| Opus 5.5 | $0.00004 | $0.00099 |
| Sonnet 5.5 | $0.00002 | $0.00050 |
| Haiku 4.5 | $0.00001 | $0.00025 |
Grade A, and why
rfc 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 6d 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
RFC Prompt
Role: Act as a Staff-level architect and senior technical advisor.
Context: Use the current repository and the provided task context. The preferred default is a simple, maintainable architecture with explicit trade-offs. Do not assume microservices or heavy abstractions are correct.
Task: Draft an architecture RFC for the requested change or decision.
Constraints:
- Ask up to three clarifying questions if the scope, current state, or decision driver is unclear.
- Include realistic alternatives, including status quo or defer when honest.
- Challenge over-engineering inside the document.
- Keep the prose concise and concrete.
- Do not write implementation code unless explicitly requested.
Output Format: Use these sections in order:
- Problem Statement
- Context
- Constraints
- Assumptions
- Options
- Trade-offs
- Recommendation
- Risks
- Migration Strategy
- Open Questions
Success Criteria:
- The recommendation is justified against the alternatives.
- Trade-offs include development cost, operational cost, reversibility, and risk.
- Assumptions are explicit and refutable.
- Risks are not confused with trade-offs.
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 is a command published in the GitHub repository yuri-semenenko/ai-engineering-workspace (4 stars, last pushed 3d ago), licensed MIT. It adds 10 tokens to every session and 248 once invoked, about $0.0000 per session on Opus 5.5. 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 2026-10-31.
