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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00048 | $0.00324 |
| Opus 5 | $0.00024 | $0.00162 |
| Sonnet 5 | $0.00010 | $0.00065 |
| Haiku 4.5 | $0.00005 | $0.00032 |
Grade A, and why
changelog-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 8d 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
Run git log --oneline to get the recent commits. Ask the user: "What version number is this release, and what date?"
Then produce a changelog entry:
[Version] — [Date]
Added
New features visible to users. One bullet per feature. Start each bullet with a verb (e.g. "Added ability to…", "New export option for…").
Changed
Behavior that changed for existing users. Flag anything that changes how something works, even if it's an improvement.
Fixed
Bugs that were resolved. Be specific — "Fixed crash when uploading files larger than 10MB" not "Fixed bugs."
Removed
Features or settings that are gone. If something was deprecated, this is where it moves to.
Security
Security fixes always get their own section, even if minor.
Rules:
- Write for users, not engineers — no commit hashes, branch names, or internal ticket IDs
- If a commit message is too technical to translate, ask what the user-facing impact was
- One bullet per change — don't merge multiple changes into one line
- Present tense: "Adds…" or past tense: "Added…" — pick one and be consistent
Append the entry to CHANGELOG.md if it exists. Create it if it doesn't.
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.
