What is claude-code-cmv?

Claude-code-cmv brings git-like version control to Claude Code sessions, letting you snapshot accumulated context, branch into fresh sessions from any point, and trim bloat for 50-70% smaller payloads without losing conversations. Built in TypeScript as a CLI tool with a Ranger-style TUI dashboard, it reads from ~/.claude/projects/, so you run `cmv snapshot "analysis" --latest` after a deep dive, then `cmv branch "analysis" --name "auth"` for task-specific forks. No more starting from scratch or relying on destructive /compact—your Claude code agents reuse full history.

Why is it gaining traction?

Unlike Claude's built-in /fork or /compact, cmv offers named snapshots, lineage trees (`cmv tree`), lossless trimming of tool results and signatures, and portable .cmv exports for team sharing. The TUI shows token breakdowns and trim potential, while CLI completions speed workflows; it's the missing claude code cli layer for chaining context across days. Developers hook on the "analyze once, branch everywhere" pattern, dodging context limits in long Claude code docs sessions.

Who should use this?

Claude Code power users knee-deep in codebase analysis, like backend engineers mapping monoliths or teams onboarding juniors via shared snapshots. Ideal for claude github pr review workflows where you fork context for fixes without re-uploading repos, or solo devs trimming bloated claude code skills sessions before branching to features.

Verdict

Grab it via git clone and npm link if Claude Code is your daily driver—detailed docs and install guides make claude code download/install straightforward, even on Windows. At 36 stars and 1.0% credibility, it's early (no tests visible), so test on non-critical work, but the core cmv delivers immediate value over claude github copilot alternatives.
