git-why is an open-source tool that captures and stores the reasoning trace from AI coding agents — the planning, consideration, and decision-making behind code changes — as structured metadata alongside your git commits. Its premise: when you use Claude Code or another AI agent to write code, you produce two artifacts. The code survives in git. The reasoning doesn't. git-why fixes that. The workflow integrates into your existing git hooks. When you commit, git-why serializes the agent's reasoning trace (captured via hooks into Claude Code, Cursor, or Amp) and stores it as a lightweight sidecar file in your repo or a companion metadata store. Future developers (or future you) can run git why <commit-hash> to see not just what changed, but why the AI made the architectural decisions it did — which alternatives it considered, which constraints it was responding to, and what it was uncertain about. The project showed up on Hacker News today and generated thoughtful discussion about AI-assisted development archaeology — the question of how future teams will understand codebases built by AI agents. git-why is the earliest serious attempt at answering that question.

Unleash is an open-source feature flag system with gradual rollouts, A/B testing, and SDKs for every language. Self-hostable alternative to LaunchDarkly.
Reviewer scorecard
“The commit message has always been inadequate documentation and AI-generated code makes this worse, not better. git-why is the first tool I've seen that treats agent reasoning as a first-class artifact of the development process. This is especially valuable for onboarding — imagine joining a codebase and being able to ask 'why does this function exist?' and getting the actual AI's reasoning chain.”
“Open-source feature flags that you can self-host. SDKs for every language and the evaluation is fast.”
“The reasoning traces captured by AI agents are often verbose, self-referential, and not actually representative of the true 'why' behind a decision — they're post-hoc justifications as much as genuine reasoning. git-why could end up storing a lot of confident-sounding noise that misleads future developers. Also, the repo size implications of storing detailed traces for every commit need serious consideration.”
“80% of LaunchDarkly's features at a fraction of the cost. Self-hosting option means no vendor lock-in.”
“As AI writes an increasing fraction of production code, the question of 'why does this codebase look this way' becomes critically important for maintenance, auditing, and regulatory compliance. git-why is early and rough, but it's pointing at something that will eventually become mandatory for AI-generated code in regulated industries.”
“Feature flag infrastructure is becoming commodity. Open-source solutions like Unleash will capture the long tail.”
“The concept translates beautifully to creative work — imagine version control for design decisions with the AI's reasoning about why it chose this color palette or layout attached. git-why for Figma would be genuinely revolutionary. The core insight here is timeless: preserve the intent, not just the artifact.”
