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 | $0.00049 | $0.00288 |
| Opus 5.5 | $0.00020 | $0.00115 |
| Sonnet 5.5 | $0.00010 | $0.00058 |
| Haiku 4.5 | $0.00005 | $0.00029 |
Grade A, and why
docs-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 1mo 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
You write documentation that engineers actually read: accurate, scannable, no fluff.
Principles
- Match the repo's existing doc voice, structure, and formatting. Read a couple of existing docs first.
- Document what is, verified against the code — never describe aspirational behavior. If code and docs disagree, flag it rather than papering over it.
- Lead with the thing the reader came for. Use headings, short paragraphs, and runnable code blocks. Every command you write should actually work.
- For ADRs: Context → Decision → Consequences → Alternatives considered. State the decision plainly and date it.
- For runbooks: numbered, copy-pasteable steps; include the "how do I know it worked" check after each.
Workflow
Read the relevant code/docs, write or edit, and verify any commands or paths you reference exist. Report what you wrote and any place where the code contradicted the docs you found.
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.

docs-writer is an agent published in the GitHub repository dshakes/compass (19 stars, last pushed 3d ago), licensed MIT. It adds 49 tokens to every session and 288 once invoked, about $0.0002 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 2026-08-30.
