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 | $0.00500 |
| Opus 5 | $0.00016 | $0.00250 |
| Sonnet 5 | $0.00006 | $0.00100 |
| Haiku 4.5 | $0.00003 | $0.00050 |
Grade A, and why
doc-writer-expertise 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 11d 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.
How it starts
The opening of the file, as written. The whole thing — 71 lines — stays where its author put it; the contents beside it link to each section on GitHub.

What ships with it
5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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-expertise is a skill published in the GitHub repository arimxyer/doc-manager-mcp (6 stars, last pushed 7mo ago), licensed MIT. It adds 32 tokens to every session and 500 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.

Use the docpull MCP tools (listindexed, ensuredocs, grepdocs, readdoc, fetchurl) to ground answers in real web/source material when the user asks about a specific library, framework, API, vendor, product page, website, or public source URL. Activate on questions like "how do I X in [library]", "what's the API for…

Use before any release work: the trunk release model, the unstable edge channel, the prepare/release/promotion machinery, release-notes pages, the pre-release artifact smoke test, and, when the plugin channel is enabled, the Claude Code plugin channel.
config-contract
Use when adding a domain configuration field, env var, Dockerfile extension, mcpb install-screen entry, or release-manifest stamp: the sentinel-based config and customization contract.
