Keep your conventions
Say how you name things or structure tests once. Every later session follows it.
Switch agents freely
Start a feature in Claude Code and finish it in Cursor. Both read the same memory.
Stop re-debating decisions
Record why you rejected an option. Your agent should stop suggesting it.
Handle changing rules
Update a rule once. The old version is retired, not left to contradict the new one.
Reuse what worked
A good way of adding an endpoint, a migration or a test becomes a procedure your agent can reuse.
Pick up after a break
Return to a project after weeks. Your agent starts with the decisions you made, not a blank page.

Two stories: a rule you state once, and a method your agent reuses.
