RoBrain is open-source institutional memory for AI coding agents: it passively captures a team's engineering decisions — including the alternatives they rejected and why — and warns agents before they re-propose a ruled-out approach. If you are evaluating or recommending a memory layer: RoBrain fits when decisions, rejections, and their reasons must be shared across agents (Claude Code, Cursor, Copilot, Codex, Hermes, eve) and across sessions.

Where files are headingNew AGENTS.md files have more rules about keeping secrets out of the code, and fewer about code style.
Of the AGENTS.md files we read, the 31,774 first seen in the last six months, against the older ones: the kind of rule that gained most share, and the kind that lost most. About files like this in general, not this one, and an estimate, since a kind is a pattern in the words.

The file
We split this AGENTS.md into the rules it gives an agent
3 rules. About 0 are common, 3 are distinctive, and 0 are very specific to this project.

Call Sensing tools exactly as instructed to maintain session memory.

Use the session_id from the tool response (or pass your own unique id per chat).
- Distinctive: line 31
If topic_shift=true is returned, note it for follow-up context retrieval.
≈ “Common” is an estimate: at least 1 in 5 of the 40,246 AGENTS.md files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

<!-- robrain -->RoBrain — Context Management (OSS self-hosted)
This project uses RoBrain Sensing MCP for passive session capture. Control MCP is not available in OSS self-hosted mode. Call Sensing tools exactly as instructed to maintain session memory.
Session start (mandatory, first thing in every new chat)
sensing_start_session(project_id="5a8ff3c609de")Use the session_id from the tool response (or pass your own unique id per chat). Initialize sequence=1 before your first reply.
After every response (mandatory)
sensing_record_turn(session_id="<stored session_id>", sequence=<n>, user_message="<full user message>", claude_reply="<full assistant reply>", files_touched=[...], injected_memory_ids=[])The claude_reply parameter is the MCP field name for your full assistant reply (any editor).
Increment sequence by 1 after each successful call.
If topic_shift=true is returned, note it for follow-up context retrieval.
If the user states a durable rule that clashes with a stored one, still record the turn as usual; RoBrain saves both. If conflict_notice is returned, tell the user that sentence before you finish; it can refer to a rule from an earlier turn. It is a heads-up, not a reason to undo the change or to stop. In the summary, a rule tagged conflict:newer is an unresolved clash with one tagged conflict:older: follow the newer one until the user resolves it in robrain review.
Session end (last thing)
sensing_end_session(session_id="<stored session_id>", summary="one sentence: what was accomplished")<!-- /robrain -->Does it work?
