Ccm

Ccm: Command-line tool that measures source code, analyzes changes, and estimates AI and human resource costs.

CCM is a fast command-line tool written in Rust that measures source code, analyzes software changes, and estimates required resources. It provides instant code inventories including languages, file counts, and lines of code. When reviewing changes, it compares project snapshots to trace edit impacts, identifies checks that need re-running, and estimates budgets across AI agents and human reviews. Outputs include terminal tables, HTML reports, and structured formats like JSON, NDJSON, and CSV. It runs entirely locally on the user machine without external dependencies or telemetry.
