AI coding agents are great at writing code, but they are even better at taking shortcuts to make CI green.

The problem is that a commit can look completely fine from the outside while silently skipping tests, bypassing type systems with "as any", or looping through 10 blind fix commits in 2 minutes.

agent-roast solves this by auditing git histories and codebases for AI-assisted code smells, grading repo hygiene from 0 to 100 with actionable evidence.

Everything stays local. No cloud, no telemetry, no API keys needed.

npx agent-roast

npx agent-roast --json

agent-roast detects 7 key failure patterns, including stealthy test skipping, aggressive type casting, panic loops, and commit velocity anomalies.

Zero telemetry. 180ms execution. Works with Cursor, Claude Code, Copilot, and Codex workflows.
