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 | $0.03000 | $0.03000 |
| Opus 5.5 | $0.01200 | $0.01200 |
| Sonnet 5.5 | $0.00600 | $0.00600 |
| Haiku 4.5 | $0.00300 | $0.00300 |
Grade A, and why
cicadas 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.
How it starts
The opening of the file, as written. The whole thing — 151 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository. It is not used by Cursor, Antigravity, Rovodev, or other agents — those environments use the Cicadas skill file (SKILL.md / cicadas.mdc) alone, which includes the same implementation guardrails.
Python / Environment
Tests are written in unittest style and are commonly run with uv run pytest. The project currently declares pytest and pytest-cov in the dev dependency group in pyproject.toml, and recent CLI coverage was verified with uv run pytest.
Commands
Run all tests:
uv run pytest
Run a single test file:
uv run pytest tests/test_kickoff.py
Run the context-template regression checks:
uv run pytest tests/test_templates.py
Run a single test:
uv run pytest tests/test_kickoff.py -k test_basic_kickoff
Run with coverage:
uv run pytest --cov=src/cicadas/scripts --cov-report=term-missing
Lint:
source .venv/bin/activate && ruff check src/ tests/

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.
