Show HN: Git for AI Agents

· ai ai-agents coding · Source ↗

re_gent adds version control for AI agent activity—tracking every tool call, prompt, and file change automatically, without manual commits, so you can audit or rewind agent sessions.

What Matters

  • Every Claude Code tool call creates a cryptographically linked Step stored in .regent/ using BLAKE3 content-addressed blobs and SQLite indexing.
  • rgt blame src/file.go:42 returns the exact prompt text that caused a specific line to be written.
  • Steps form a DAG; each agent session gets its own branch, eliminating merge conflicts from concurrent agents.
  • Conversation history survives /compact and /clear because transcripts are stored per-step, not per-session memory.
  • rgt rewind (non-destructive time-travel to any prior step) is listed as coming soon; core commands—init, log, blame, show, sessions—are complete.
  • ~7,800 LOC Go implementation; VSCode extension provides inline blame annotations via direct SQLite integration, no subprocess overhead.
  • Complements git rather than replacing it; .regentignore support mirrors standard gitignore behavior.
