Lore

Reasoning history for code. Lore captures AI coding sessions and links them to git commits.

Lore saves all your AI coding sessions from Claude Code, Codex, etc and links them to commits. When you look at code later, you can see the conversation that produced it.

Documentation: lore.varalys.com

Use Cases

• Code review: See the AI conversation that produced a PR, not just the diff
• Debugging: Understand why code was written a certain way
• Knowledge transfer: AI conversations stay with the code when people leave
• Search: Find that conversation where you solved a similar problem

Homebrew (macOS)

brew install varalys/tap/lore

      ...decided on 5 attempts as the threshold based on industry standards...
      Let me add rate limiting to prevent brute force attacks.

Key Features

Supported Tools

Claude Code, Codex CLI, Gemini CLI, Amp, Aider, Continue.dev, Cline, Roo Code, Kilo Code, OpenCode
