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 | $0.00914 | $0.00914 |
| Opus 5.5 | $0.00366 | $0.00366 |
| Sonnet 5.5 | $0.00183 | $0.00183 |
| Haiku 4.5 | $0.00091 | $0.00091 |
Grade A, and why
agents 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 5d 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 — 98 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Bitrefill Skills — Agent Guide
Instructions:
- Be semantically dense and token efficient. Prefer concise, information-rich responses; avoid filler, repetition, and unnecessary elaboration.
- Whene editing, never mention the previous version or the changes you made. All the contents must be authoritative and up to date.
- Try abstracting instructions that can be applied to multiple cases
- Avoid creating new sections as much as possible. Try updating exisiting knowledge instead.
This repository is a monorepo of agent skills for Bitrefill, packaged as a Claude Code / Cowork plugin marketplace. Skills live in the skills/ directory and are distributed through the plugin system shared by Claude Code and Claude Cowork.

The marketplace (marketplace.json) lists plugins available for installation. The plugin manifest (plugin.json) defines the plugin's identity. Skills inside skills/ are auto-discovered when the plugin loads. MCP servers in .mcp.json start when the plugin is enabled.
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.
