Git why – log your agent reasoning trace along your code
I was frustrated with not being able to know why the code written by my colleague agents was in the codebase, so I build a tool to version agent trace along code in git.

In plain words
Git why is a version control tool that logs AI agent reasoning traces alongside code in Git repositories. It helps developers understand the decision-making process behind code written by AI agents by storing traces with commits. The tool is designed for teams using AI coding assistants who need visibility into why specific code changes were made and what reasoning led to those decisions.

git-why is an open protocol for storing reasoning traces alongside your source code. It preserves the conversations and decisions that shaped every line. AI-assisted development creates two artifacts. Only one survives. $ git blame src/auth.py a3f1c9d2 Pierre line 42: @retry(max=3, backoff="expo") a3f1c9d2 Pierre line 43: def refresh_token(self): $ git log --oneline -1 a3f1c9d2 Add retry to auth refresh What git-why preserves $ git why show src/auth.py ## Add retry with exponential backoff Reasoning: Considered circuit breaker (too heavy), fixed delay (thundering herd risk), and exponential backoff with jitter (chosen) . Prompt: "Add retry logic when the auth token refresh fails" Built for…from hexapode.github.io

Git for AI AgentsMay 2026 · github.com · ▲129hi guys. been working on something i think is fundamentally missing in today's workflow with ai agents. vcs. i find myself struggling with questions that agents can't answer like "why did you do it?", "when did u delete this folder? why?", etc. or trying to /rewind (after a /compact...) or basically `bisect` to find when and why something was done by the agent in the current / previous session. just like git did for code, i think we are the same core capabilities with ai agents so... i developed an open source solution for that (currently supporting claude code) would love to…
git-lrcFeb 2026 · hexmos.com · ▲300Hi HN, I'm the author of git-lrc, would appreciate some feedback from the community Last year my team started using AI coding tools more heavily, and we found ourselves generating tons of code, but spending less time looking at the stuff that's been generated. We felt like we were losing a bit of grip/understanding of what we were building. Regressions occasionally slipped through. Sometimes changes made it all the way to production only to be reverted later. We tried several AI code review tools, but most operate at PR time. That felt too late. I wanted review to happen while the…

With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
