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 | $0.00190 | $0.00190 |
| Opus 5.5 | $0.00076 | $0.00076 |
| Sonnet 5.5 | $0.00038 | $0.00038 |
| Haiku 4.5 | $0.00019 | $0.00019 |
Grade A, and why
skills CLAUDE.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
ReadyCheck Skills Repository Policy
This repository is the published Claude Code marketplace and plugin source for ReadyCheck.
Release Policy
- Do not update
plugins/readycheckby pushing changes directly to this repository. - Do not bump the ReadyCheck plugin version in
.claude-plugin/marketplace.jsonmanually in this repository. - The published ReadyCheck plugin and marketplace version must be updated only by the GitHub
Releaseworkflow inreadycheck-dev/ReadyCheck. - If a new ReadyCheck plugin version is needed, trigger the
Releaseworkflow fromreadycheck-dev/ReadyCheckonmain.
Reason
readycheck-dev/ReadyCheckis the source-of-truth repository.- Its release workflow packages the runtime, prepares the published plugin source, and syncs this repository in one step.
- Direct pushes here can desynchronize the marketplace from the published release assets and break plugin upgrades.
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.
