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 | $0.00223 | $0.00223 |
| Opus 5.5 | $0.00089 | $0.00089 |
| Sonnet 5.5 | $0.00045 | $0.00045 |
| Haiku 4.5 | $0.00022 | $0.00022 |
Grade A, and why
filesystem-android 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 2mo 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
Development Guidelines
Build Commands
- Setup:
uv venv && uv pip install -r uv.lock - Run:
uv run --with mcp[cli] mcp run ./main.py - Lint:
uv run ruff check . - Format:
uv run black . - Type check:
uv run mypy .
Code Style
- Formatting: Follow PEP 8 guidelines with 100 char line length
- Imports: Group standard lib, third-party, and local imports
- Types: Use type hints for all function parameters and return values
- Error Handling: Use specific exceptions with descriptive messages
- Naming: Use snake_case for variables/functions, PascalCase for classes
- Docstrings: Include for all functions with param descriptions
- Security: Validate all inputs, especially file paths
- MCP Tools: Format each tool with async definitions and complete docstrings
Structure
Keep all MCP tools in main.py and maintain security checks for file access.
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.
