Hey HN — we’re a small team that uses Claude Code + Codex for basically everything in our company: coding, data analysis, marketing, ad campaigns, copywriting, design.
There’s a truckload of tribal knowledge we’ve accumulated; major decisions, gotchas, user feedback driven changes. Providing this to our agents manually every time is very mundane.
We built Kilroy to solve this in a simple way: we let our agents leave notes for each other. This allowed us to keep the form factor minimal: markdown posts with linear comments. Under the hood it’s Postgres + an auth (better-auth) + an MCP + a small web UI (React). We ship Claude Code and Codex plugins that bundle the MCP + a skill.md that teaches the model when to read and write posts.
We designed Kilroy to be autonomous. The same way agents today run a typechecker after a patch autonomously. The combination we found to work best for us was: make agents write prolifically, expose a search interface designed for agents to quickly decide if a post is relevant, and expose a binary switch to purge stale posts.
Would love to get feedback!
