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 | $0.00208 | $0.04099 |
| Opus 5 | $0.00104 | $0.02049 |
| Sonnet 5 | $0.00042 | $0.00820 |
| Haiku 4.5 | $0.00021 | $0.00410 |
Grade A, and why
docs 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 2d 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 — 334 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Documentation
Author, audit, and maintain project documentation across every surface that matters: the agent hot path (CLAUDE.md, AGENTS.md, .claude/rules/), the human entry point (README.md), and the narrative tier (docs/).
This is the single home for "make our docs good" work — bootstrapping a new project, refreshing docs after a sprint, writing a README that converts readers into users, or auditing the whole estate for drift.
This
SKILL.mdis a thin index. Detailed authoring rules live inrules/*.mdand load on demand. Worked examples are inreferences/*.md. Literal scaffolding skeletons are intemplates/*.md. Do not preload everything — load only what the current phase asks for.
Mode Detection
Parse $ARGUMENTS (first token) and route to one of four modes.
A second token of --auto is a cross-cutting modifier (see below).
| Mode | Default | Trigger |
|---|---|---|
init |
"init", "bootstrap", "scaffold", or $ARGUMENTS == "init" (no existing CLAUDE.md). |
|
update |
yes | Default when a CLAUDE.md already exists. "update", "sync", "refresh", "drift". |
readme |
"readme", "write a README", "audit the README", or $ARGUMENTS == "readme". |
|
audit |
"audit", "review the docs", "doc health check", or $ARGUMENTS == "audit". |
--auto modifier — append to any mode token to enable the autonomous-workflow guardrails.
Always passed by autonomous-workflow Phase 5 as Skill("docs", "update --auto").
When --auto is present, also load auto-update-loop.md before executing the mode's phases.
Disambiguation rule when no mode token is passed:
- If
./CLAUDE.mddoes not exist →init. - Else if
./README.mddoes not exist and the user mentioned "README" →readme. - Else →
update.
What ships with it

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.
- 2d ago First seen · 334 lines · 208 tokens per session scan A 12cf8db283a5
docs is a skill published in the GitHub repository mthines/agent-skills (10 stars, last pushed 3d ago), licensed MIT. It adds 208 tokens to every session and 4,099 once invoked, about $0.0010 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.
