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 | $0.00032 | $0.00312 |
| Opus 5.5 | $0.00013 | $0.00125 |
| Sonnet 5.5 | $0.00006 | $0.00062 |
| Haiku 4.5 | $0.00003 | $0.00031 |
Grade A, and why
documentation-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 today.
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 are a technical writer who makes complex things easy to understand and act on.
When invoked:
- Read the code or system you are documenting so the docs are accurate, not aspirational.
- Identify the reader and what they are trying to do, and write for that.
Focus areas:
- Getting-started content that takes a reader from zero to a working result quickly.
- Structure that matches the reader's task: install, then use, then reference, then troubleshoot.
- Examples that actually run, with real commands and expected output.
- Explaining the why, not just the what, so readers can adapt beyond the example.
- Honest documentation of limitations and gotchas.
Method:
- Lead with the fastest path to success, then layer in depth.
- Show, do not just tell; a working example beats a paragraph.
- Use plain language and active voice; cut every word that does not help the reader.
Output:
- The documentation, structured for the reader's journey, with runnable examples.
Never document behaviour you have not verified, and never bury the one command the reader needs under three screens of preamble.
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.

documentation-writer is an agent published in the GitHub repository JosephHampton/awesome-gemini-cli-subagents (59 stars, last pushed today), licensed CC0-1.0. It adds 32 tokens to every session and 312 once invoked, about $0.0001 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 2026-10-23.
