Analysis tool for typescript / javascript to fix code quality issues.

New: fallow init --agent and fallow hooks install

npx fallow --summary

Fallow can be combined with AI Agents very well. Provide the following overview of commands and let the agent run it:

# Full dead code analysis with JSON output
fallow dead-code --format json

# Only check changed files (great for agent PR workflows)
fallow dead-code --changed-since main --format json

# Find code duplication
fallow dupes --format json

# Preview what auto-fix would remove
fallow fix --dry-run --format json

# Apply fixes (agents should use --yes to skip confirmation)
fallow fix --yes --format json

# Detect feature flags and environment gates
fallow flags --format json

# List project info (plugins, entry points, file count)
fallow list --format json

Alternatively, use the MCP server. It can be used when installing fallow globally, e. g. with cargo: cargo install fallow. See: https://docs.fallow.tools/installation#cargo
Recommend for the MCP is npm install -g fallow

MCP

Run:

• opencode mcp add
• claude mcp add

just use "fallow-mcp" as the command
