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 | $0.00203 | $0.00203 |
| Opus 5.5 | $0.00081 | $0.00081 |
| Sonnet 5.5 | $0.00041 | $0.00041 |
| Haiku 4.5 | $0.00020 | $0.00020 |
Grade A, and why
FCoP AGENTS.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 29d 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
FCoP source repository
- This repository develops the FCoP Python library and its optional MCP adapter.
- Core is the sole authority for protocol facts, validation and state transitions.
- Canonical MCP is a thin Core adapter; its manifest owns the exposed tool surface.
- Keep Runtime, CodeFlowMu, Profile presets, Host configuration and Legacy compatibility outside Base Protocol.
- Preserve existing user changes. Use UTF-8; do not edit Chinese text with PowerShell.
- Source:
src/fcop/; MCP:mcp/src/fcop_mcp/; tests:tests/. - Run relevant tests with
python -m pytest; run lint withpython -m ruff check. - Local package builds use
python -m buildat the repository root and inmcp/. - Validate local wheels in a clean environment before claiming release-candidate readiness.
- Do not automatically publish packages, upload to PyPI, create tags or Releases, or merge changes.
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.
