Before each task
- memstate_get(project_id="myproject") — browse existing knowledge - memstate_search(query="topic", project_id="myproject") — find by meaningAfter each task
- memstate_remember(project_id="myproject", content="## Summary\n- ...", source="agent")Tool guide
- memstate_remember — markdown summaries, decisions, task results (preferred) - memstate_set — single short values only (config flags, status) - memstate_get — browse/retrieve before tasks - memstate_search — semantic lookup when keypath unknown - memstate_history — audit how knowledge evolved - memstate_delete — remove outdated memories (history preserved) ```---
