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 | $0.00036 | $0.00167 |
| Opus 5 | $0.00018 | $0.00084 |
| Sonnet 5 | $0.00007 | $0.00033 |
| Haiku 4.5 | $0.00004 | $0.00017 |
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 3d 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
Write docs for the @stag-build/phonebook project. Rules:
- Ground every claim in the actual code or PLAN.md — read the relevant source before documenting a command or config key; never document behavior you did not verify exists.
- Audience: mobile developers integrating the tool. Short sentences, copy-pasteable commands, one happy path first, edge cases after.
- Match the tone and structure of existing docs in the repo.
- Report which files you touched and any code/doc mismatches you noticed (do not fix code).
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 stag-build/phonebook (8 stars, last pushed 4d ago), licensed MIT. It adds 36 tokens to every session and 167 once invoked, about $0.0002 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 2026-08-31.
