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 | $0.00023 | $0.00279 |
| Opus 5 | $0.00012 | $0.00139 |
| Sonnet 5 | $0.00005 | $0.00056 |
| Haiku 4.5 | $0.00002 | $0.00028 |
Grade A, and why
update 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.
What it actually says
Kind-1 self-update — the agent verifies (online), the hook only schedules (it never networks). If git/network is unavailable, say so and suggest updating manually later (never assume either exists).
- Check. Web-check the latest published CoalWash tag (any means available — the GitHub releases/tags page or API) vs the installed
versionin.claude-plugin/plugin.json. - Offer (consent-gated — the only token spend). Newer available → OFFER
claude plugin update coalwash@coalwash(then restart); on a file-copy install, offer to re-copy the updated files instead. Already current → say so in one line. - Cadence. To change how updates are handled, set
updateMode(ask|auto|remind|off) andupdateCheckDaysin.coalwash.json.autolets this check run when due without re-asking;offsilences it entirely.
Security note: CoalWash mutates memory — fidelity/safety fixes matter more than cosmetics here; still, this never auto-applies. It offers, the user runs the update.
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.
