loam

Codebase intelligence & anti-AI-slop for Dart & Flutter.

loam is the CLI command and pub.dev package name for loam.dev — a Dart-native, semantically accurate, project-wide quality tool. It surfaces what dart analyze misses: structural drift (dead code, duplication, circular dependencies, complexity hotspots, architecture boundary violations) and AI-slop — with a baseline/ratchet CI gate.

Built on the Dart analyzer package. Deterministic core (offline, free) plus an optional, cache-stabilised LLM layer.

This is the CLI package of the loam.dev monorepo. For the project overview, the founding spec and the domain glossary, see the repository root.

Install

dart pub global activate loam

Commands (target)

loam scan      # all active rules across the whole project
loam health    # score + hotspots
loam gate      # CI: baseline/ratchet (default) | --absolute
loam slop      # anti-AI-slop layer (--llm opt-in)
loam init      # materialise config + inferred layers
loam fix       # safe auto-fixes (--safe)

Output format is chosen with --format (human | sarif | json | markdown | html). --format html writes a self-contained loam-report.html you can open in a browser to toggle findings and copy a fix-prompt for an AI agent.
