Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00453 | $0.00453 |
| Opus 5 | $0.00227 | $0.00227 |
| Sonnet 5 | $0.00091 | $0.00091 |
| Haiku 4.5 | $0.00045 | $0.00045 |
Grade A, and why
cursorrules 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 yesterday.
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
CICADA - AI Assistant Guidelines
This file contains project-specific instructions for AI assistants working on the CICADA codebase.
Release Process
When creating a new release:
-
Create and push the git tag:
git tag v0.X.Y git push origin v0.X.Y -
Update README.md version references:
- Search for all instances of
@v0.1.1in README.md - Replace with the new version tag
@v0.X.Y - Locations to update:
- Quick Install section (stable release command)
- Try Before Installing section (stable release command)
- Migration tip section
- Search for all instances of
-
Update pyproject.toml version:
- Update the
version = "0.1.1"field to match the new release
- Update the
-
Test the installation:
uv tool install git+https://github.com/wende/[email protected]
Project Context
- Language Support: Currently Elixir only. Python and TypeScript are planned.
- Primary Installation Method: uv tool install (recommended over Python direct install)
- Index Location:
.cicada/directory in project root
Code Style
-
Use
blackfor Python code formatting -
Include type hints where appropriate
-
Write tests for new features
-
Keep functions focused and modular
-
When searching through the Elixir codebase, use the cicada-mcp MCP server tools instead of grep/find commands for better accuracy and context.
-
use make to run tests
Package Management
This project uses uv as the primary Python package manager. Always use uv commands:
- Install dependencies:
uv sync - Add new dependencies:
uv add <package-name> - Run commands:
uv run <command> - Install project:
uv pip install -e . - Tool installation:
uv tool install git+https://github.com/wende/[email protected]
Never use pip directly - always use uv for all Python package management tasks.
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.

cursorrules is a cursor rule published in the GitHub repository wende/cicada (40 stars, last pushed 1mo ago), licensed MIT. It adds 453 tokens to every session, about $0.0023 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
