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 | $0.00180 | $0.00180 |
| Opus 5.5 | $0.00072 | $0.00072 |
| Sonnet 5.5 | $0.00036 | $0.00036 |
| Haiku 4.5 | $0.00018 | $0.00018 |
Grade A, and why
claude-plugins-registry 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 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
Repository instructions
This repository publishes @biggora/claude-plugins, a Node.js ESM CLI and a collection of agent skills. Node.js 18 or newer is required. There is no build step.
- Run
npm cibefore validation andnpm testbefore claiming completion. - Keep shell operations on
execFileSync; do not replace them with shell-string execution. - Keep changes focused. Match the existing JavaScript style.
- When adding or changing a skill, update its
SKILL.md,registry/registry.json, README documentation, and relevant validation tests together. - Treat
registry/registry.jsonas the npm CLI catalog. The native Claude, Codex, and Copilot marketplaces have separate schemas and paths. - Preserve user files and unrelated worktree changes. Never commit secrets, credentials, generated evaluation output, or local workspace directories.
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.
