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 | $0.00031 | $0.00257 |
| Opus 5 | $0.00015 | $0.00129 |
| Sonnet 5 | $0.00006 | $0.00051 |
| Haiku 4.5 | $0.00003 | $0.00026 |
Grade A, and why
update-changelog 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 yesterday.
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
Run the update-changelog skill for the current context.
Any text after /update-changelog describes the shipped unit or significant change. Examples:
/update-changelog— infer the just-shipped unit or significant planning change from the recent conversation; ask one clarifying question if multiple candidates./update-changelog changelog-ledger shipped— log a ship line (✓) for a shipped unit of work./update-changelog spec'd changelog-ledger— log a decision line (◆) for a significant planning-artifact change.
The skill reads docs/changelog-contract.md, resolves the target CHANGELOG.md (project root, else .claude/CHANGELOG.md), classifies ship-line vs decision-line, composes a dated line in changelog voice, and shows it for accept / edit / reject before writing. One line per shipped unit, not per commit. Never auto-fires, never auto-writes.
See ~/.claude/skills/update-changelog/SKILL.md for the full procedure.
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.
