Analyze a source file for decomposition. Returns health score, function count, dependency graph, and recommended split points.

Generate a decomposition plan — module boundaries, function assignments, dependency order. Uses AST analysis + LLM reasoning.

Extract one module from the monolith according to the plan. Routes to the cheapest capable free LLM API.

Verify a decomposed module: loads without errors, exports match plan, no circular deps, tests pass.

Calculate before/after metrics and the Refactory Score (0-1). Measures health improvement, module quality, test preservation.

Generate a decomposition report with metrics, dependency graphs, and Refactory Score. Outputs Markdown or HTML.

Map dependencies for a file — who requires it (consumers), what it requires (dependencies), detect circular deps.

Generate characterization tests and golden export snapshot BEFORE decomposition. Captures behavioral contract.

Compare post-decomposition module against golden export snapshot. Reports missing, added, or type-changed exports.

Mechanically fix broken require() paths after module extraction. No LLM needed — pure path resolution.

Full decomposition pipeline in one call: analyze, depmap, characterize, plan, extract ALL modules, fix-imports, verify, metrics, re-export, report. The 'just do it' tool.
