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 | $0.05100 | $0.05100 |
| Opus 5.5 | $0.02040 | $0.02040 |
| Sonnet 5.5 | $0.01020 | $0.01020 |
| Haiku 4.5 | $0.00510 | $0.00510 |
Grade A, and why
claude-code-marketplace 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.
How it starts
The opening of the file, as written. The whole thing — 658 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Plugin System
Plugins are self-contained directories with:
- Agents: Markdown files defining specialized AI assistants for specific tasks
- Skills: Model-initiated capabilities that activate automatically based on context
- Commands: Slash commands for common workflows
- plugin.json: Metadata including name, version, author, keywords
Marketplace: The .claude-plugin/marketplace.json file registers all plugins and their locations.
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.
