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 | $0.00158 | $0.00158 |
| Opus 5.5 | $0.00063 | $0.00063 |
| Sonnet 5.5 | $0.00032 | $0.00032 |
| Haiku 4.5 | $0.00016 | $0.00016 |
Grade A, and why
mcpls 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 2mo 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 format
Breaking changes to public APIs must appear under ### Changed with an explicit
"Breaking change:" prefix. A ### Fixed entry alone is not sufficient — downstream
users scanning the changelog for breakage will miss it.
Additions of #[non_exhaustive] to existing public enums or structs are breaking
changes for crates that match exhaustively. Document the required migration (add a
wildcard arm, update struct initialisation) in the entry.
Every entry must reference the PR or issue number: (#NNN).
New entries go under ## [Unreleased]. Do not add entries directly under a versioned
section — version assignment happens in the release PR.
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.
