project

A project-rules file for groundcrew, a tool intended to provide reliable computer-state information and encode actions for computer-use agents.

In plain words
What is it for?
Use it when implementing features or changing modules in the groundcrew project.
Why use it?
It tells contributors which Python, typing, linting, documentation, testing, export, and changelog rules changes must follow.

Cursor rule for Cursor

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.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

project 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

groundcrew — Cursor Rules

What this project does

Deterministic state oracle and semantic action codec for computer-use agents

Module map

src/groundcrew/
├── # TODO: fill in after implementation

Invariants — never break these

  • TODO: list invariants

Code style

  • Python 3.10+, fully type-annotated, mypy strict mode
  • Ruff lint rules: E W F I UP B S N SIM RUF PT
  • No print() in library code — use rich.console.Console
  • All public functions and classes must have docstrings
  • Tests: pytest, CliRunner for CLI tests

When adding a new feature

  1. Implement in the appropriate module
  2. Export from init.py, add to all alphabetically
  3. Add tests in tests/test_.py
  4. Update CHANGELOG.md under [Unreleased]
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.
