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 | $0.00950 | $0.00950 |
| Opus 5 | $0.00475 | $0.00475 |
| Sonnet 5 | $0.00190 | $0.00190 |
| Haiku 4.5 | $0.00095 | $0.00095 |
Grade A, and why
pbnz-skills copilot-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 8d 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.
How it starts
The opening of the file, as written. The whole thing — 47 lines — stays where its author put it; the contents beside it link to each section on GitHub.

About this repository
This is a Claude Code plugin marketplace that also distributes Agent Skills under the open agentskills.io standard. The repository is primarily configuration and prose — it is not application code. There is no build step and no runtime beyond the Python validation scripts under scripts/.
What's in the tree
.claude-plugin/marketplace.json— marketplace manifest.plugins/<plugin>/.claude-plugin/plugin.json— plugin manifest.plugins/<plugin>/skills/<skill>/SKILL.md— skill definition. The YAML frontmatter is metadata for skill matching; the Markdown body is natural-language prompt content consumed directly by the model.plugins/<plugin>/README.md— human-facing plugin documentation..github/workflows/validate.yml,.github/workflows/release.yml— CI.scripts/*.py— Python 3.12 validation scripts used byvalidate.yml.

Where review effort adds value
Focus comments on:
- JSON manifests — required fields, SemVer-shaped
versionvalues, pluginsourcepaths that do not exist on disk, duplicate plugin names, stale references. - GitHub Actions workflows — security concerns (unsafe interpolations, overly broad permissions, untrusted action versions), correctness, and avoidable failure modes.
permissions: contents: writeonrelease.ymlis intentional and required — do not flag it. - Python scripts — bugs, edge cases, unsafe file handling. PEP 8 is expected. Python 3.12 is the target.
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.
