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 | $0.00028 | $0.00550 |
| Opus 5.5 | $0.00011 | $0.00220 |
| Sonnet 5.5 | $0.00006 | $0.00110 |
| Haiku 4.5 | $0.00003 | $0.00055 |
Grade A, and why
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 1mo 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
CHANGELOG.md follows Keep a Changelog. The release workflow publishes each tag's section and fails when it's missing. TestChangelogReleases validates version headings.
- Add user-visible framework, CLI and generated-code changes under
## [Unreleased]in the same commit. Omitdocs,test,choreandci. - Sort entries into
Added,Changed,Deprecated,Removed,FixedandSecurity. - Within a section, group entries under
####subheadings by where the change applies, in this order:`datapages lint` and `datapages gen`for what the app model may contain and what is reported about it;Generated code, opened by the line "Rundatapages gento apply these.";Runtime and modulesfor what applies on upgrade alone;`datapages init`for the files it writes. Leave out a subheading with no entries. - Don't repeat in an entry what its subheading says: no "in
datapages lintanddatapages gen" and no closing "Rundatapages gen." - Use imperative entries like commit titles:
Reject subject fields tagged json:"-". Say enough for users to determine whether they are affected. - A
Securityentry follows Security entries. - A breaking change repeats the migration steps of its
BREAKING:block. - Do not add a separate entry for a
runtime/API change. The entry for the user-visible change that requires it goes underGenerated code. - To release, rename
## [Unreleased]to## [X.Y.Z] - YYYY-MM-DD, insert an empty## [Unreleased], update the compare links and tagvX.Y.Z.
Security entries
A security entry lets users determine exposure and remediation:
- State who can read or do what to whom: "any signed-in user can read another user's private events", not "a privacy issue".
- Describe affected applications with terms users can find in their code.
- Give exact affected versions, verified against the release history.
- Give upgrade, regeneration and redeploy steps. Include a workaround or say there is none.
- Link the GHSA or CVE when one exists.
Leave severity labels, CVSS scores and exploit steps to the advisory.
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.
