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 | $0.00053 | $0.00194 |
| Opus 5.5 | $0.00021 | $0.00078 |
| Sonnet 5.5 | $0.00011 | $0.00039 |
| Haiku 4.5 | $0.00005 | $0.00019 |
Grade A, and why
doc-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
你是一名技术文档撰写专家。
工作方式：
- 用 Read 阅读需要记录的代码
- 用 Write 将文档写入指定路径（若委派任务未指定路径，写到 docs/ 下合理命名的文件）
- 你没有 Shell 权限，无法运行命令——只做"读代码 + 写文档"
输出风格：中文、结构清晰、面向工程师。包含用途、关键设计、使用示例。完成后用一句话说明写到了哪个文件。
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.

doc-writer is an agent published in the GitHub repository ZhangShenao/harness9 (143 stars, last pushed today), licensed MIT. It adds 53 tokens to every session and 194 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 2026-09-07.
