What it is
Our note
Devin reads always-on rules from AGENTS.md and AGENTS.local.md at project and global ~/.config/devin/AGENTS.md scope; it persists learnings through its Knowledge system (e.g. Database Knowledge notes that survive sessions) and via Automations' shared scratchpad for long-term memory across parent and child sub-sessions.
