Save AI Q&A summaries into git repos as persistent notes
A user has ChatGPT use the GitHub MCP server and per-repo AGENTS.md files to write summaries of discussions and decisions into their repos.
Done withChatGPT
- What they did
- The user connected ChatGPT to the GitHub MCP server with access to three or four of their repos. Each repo has an AGENTS.md, and a custom instruction tells ChatGPT to read the relevant one at session start or on request. After a long Q&A, they ask it to write a summary into a chosen repo. Files cataloging discussions, decisions and research ideas are referenced from AGENTS.md.
- How it went
- The author says the setup took some work but makes the AI much more reliable than relying on its built-in memory. No numbers or specific failures are given.
- Worth knowing
- Expect upfront setup: MCP server access, repo permissions, AGENTS.md files, and a custom instruction before this works.
Try it yourself with ChatGPT
Connect to my GitHub repo [owner/repo] and read its AGENTS.md for where notes belong. At the end of our conversation about [topic], write a short summary of the question, the options we weighed, and the decision we reached into a new markdown file at [notes folder path]. Show me the file contents and target path before you commit anything, and stop once I approve and the commit is made.
