pycoati

Audits Python test suites for mock smells and suspicious tests. Walks a project with tree-sitter, optionally runs pytest for collection, durations, and coverage, and emits a structured inventory: per-file and per-test counts, mock-API smells, and a per-test suspicion score.

Install

# From source (Rust)
cargo install --path .

# Or as a Python package (via maturin)
maturin develop

Usage

pycoati --help

`pycoati <PATH>`

Audit a project directory or a single .py file. Writes the inventory to stdout as JSON unless --output is given.

# Structured inventory to a file
pycoati . --output inventory.json

# Aligned-column terminal view
pycoati . --format pretty

# Static analysis only, no pytest subprocesses
pycoati . --static-only

Key flags: --format <json|pretty>, --output <PATH>, --tests-dir <PATH>, --static-only, --no-coverage, --top-suspicious <N>, --project-package <NAME>, --python <CMD>, --pytest-args <STR>, --member-cwd <root|member>. See pycoati --help for the full list.

Weights behind suspicion_score are documented in WEIGHTS.md.

`pycoati guide [PAGE]`

Prints the workflow instructions that ship inside the binary, aimed at a coding agent working through an audit. Because the pages are embedded at compile time, they always describe the inventory schema this exact build emits.

# Pick the page from the state of the current directory
pycoati guide

# Or ask for one by name
pycoati guide setup
pycoati guide analyze
pycoati guide remediate

Page	Contents
`setup`	Configuration surface, how to run the scan, where `inventory.json` lands.
`analyze`	Field reference for every key in the inventory, plus the anti-pattern taxonomy and its detection heuristics.
`remediate`	The remedy ladder, the human-approval gate, and the "do not" list.

With no argument, the page is chosen from the current directory: analyze when an inventory.json is present there, otherwise setup. remediate is never auto-selected — reach it via the analyze page's breadcrumb or by name.

The subcommand shadows a directory of the same name: if you have a ./guide directory to audit, write pycoati ./guide.

Each page ends with a single next: line, so an agent is always one command away from the right instructions. A --format pretty scan that finds candidates ends with the same breadcrumb; JSON output never carries it.

The page sources are plain markdown under docs/guide/, embedded via include_str!. tests/guide_schema_drift.rs asserts that every field name serde emits is documented on the analyze page, so a schema change cannot land without the guide being updated alongside it.

Development

# Pre-commit checks
