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 | $0.00047 | $0.00427 |
| Opus 5 | $0.00023 | $0.00214 |
| Sonnet 5 | $0.00009 | $0.00085 |
| Haiku 4.5 | $0.00005 | $0.00043 |
Grade A, and why
doncheli-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 12d 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
Don Cheli: Changelog Auto-Generator
Instructions
- Determine the commit range:
- Default: from the last semver tag to HEAD
- With
--from/--to: use the specified refs - With
--version: use that as the new version number
- Run
git log --oneline <range>and parse conventional commit prefixes - Map commit types to Keep a Changelog categories:
feat/feat!→ Added (breaking changes go in a separate top section)fix→ Fixedrefactor/perf→ Changeddocs→ Changedsecurity→ Securitydeprecated→ Deprecatedremove→ Removedtest/chore/ci→ omit by default (include with--verbose)
- Extract the short hash and append it to each entry for traceability
- Skip merge commits (
Merge branch,Merge pull request) - Insert the new section at the top of
CHANGELOG.md, below the header — never overwrite existing entries - If no
CHANGELOG.mdexists, create it with the standard Keep a Changelog header - With
--dry-run, print to stdout only — do not write to file - After writing, confirm with the user and suggest
git add CHANGELOG.md
Quality Gate
- If fewer than 2 commits are found in the range, warn the user before generating
- If breaking changes are detected (
feat!,BREAKING CHANGEfooter), highlight them prominently - Never infer a version number from non-semver tags — ask the user to provide
--version
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.
