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 | $0.00215 | $0.00215 |
| Opus 5.5 | $0.00086 | $0.00086 |
| Sonnet 5.5 | $0.00043 | $0.00043 |
| Haiku 4.5 | $0.00021 | $0.00021 |
Grade A, and why
packmind packmind-changelog.instructions.md 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
Standard: Changelog
Maintain a consistent and well-structured CHANGELOG.MD file following the Keep a Changelog format to ensure all releases are properly documented with accurate version links and dates. This standard ap... :
- An entry of the CHANGELOG should not exceed 200 characters
- Ensure all released versions have their corresponding comparison links defined at the bottom of the CHANGELOG.MD file in the format [X.Y.Z]: https://github.com/PackmindHub/packmind/compare/release/...release/X.Y.Z
- Format all release dates using the ISO 8601 date format YYYY-MM-DD (e.g., 2025-11-21) to ensure consistent and internationally recognized date representation
- Maintain an [Unreleased] section at the top of the changelog with its corresponding link at the bottom pointing to HEAD to track ongoing changes between releases
Full standard is available here for further request: Changelog
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.
