Cognition compare
Cognition vs Cursor Rules
Cursor Rules shape how Cursor's agent behaves in a workspace or globally. Cognition is a memory service your Cursor agent calls through MCP, so approved skills can also load in Codex, Claude Code, and Gemini.
Cognition is for
You and your coding agents
Cursor users who also run other coding agents, or who want skills captured from sessions with approval, provenance, and reuse receipts instead of only static rule files.
Cursor Rules is for
Their primary user
Cursor-only workflows where checked-in or user rules are enough and you do not need a shared skill layer across hosts.
Side by side
| Aspect | Cognition | Cursor Rules |
|---|---|---|
| Configuration surface | MCP tools plus optional thin Cursor rule block | Project rules, user rules, and legacy .cursorrules files |
| Persistence model | Skills stored against your brain address with API access | Rules live in Cursor settings or repo paths Cursor reads |
| Cross-tool reuse | Same skills available in Codex, Claude Code, Gemini | Scoped to Cursor unless you manually copy rules elsewhere |
| Capture from work | Draft skill from session, approve, then reuse | Rules can be written, generated from conversations, or shared by a team |
| Hosted updates | Pedagogy can update from server when stub checks version | You edit and commit rule files locally |
When to pick Cursor Rules
- You only use Cursor and prefer all guidance in repo-local rules.
- You do not want an MCP dependency or personal API key.
How they work together
Use Cursor Rules for repo-specific conventions that should always apply. Use Cognition for skills learned from incidents and reviews that should survive across agents and sessions.
