The deterministic resolver from #5076 silently rebucketed every user who hadn't set MEM0_USER_ID. With MEM0_API_KEY present (the normal case — hooks early-exit without it), the resolver picked "mem0-<sha256(api_key)[:12]>" instead of $USER, so an existing "deshraj" bucket suddenly became "mem0-f34dd1cba657" on update with no migration. The old memories aren't reachable from the plugin anymore, and the user gets a fresh empty bucket without warning. Resolution priority is now back to: 1. MEM0_USER_ID env var 2. \$USER, else "default" The ~/.mem0/identity.json cache is no longer written or read; any existing cache file becomes inert. Users on multiple machines who want a single bucket can still set MEM0_USER_ID explicitly — that's the supported path, not silent derivation. Also dropped the "regardless of which machine you're on" line from the session bootstrap header since it no longer applies.

## Mem0 Session Bootstrap
|
|
|
|
You have access to persistent memory via the mem0 MCP tools. Before doing anything else:
|
|
|
|
1. Call `search_memories` with a query related to the current project or user request to load relevant context.
|
|
2. Review the returned memories to understand what has been learned in prior sessions.
|
|
3. If appropriate, call `get_memories` to browse all stored memories for this user.
|
|
|
|
IMPORTANT: Do NOT skip this step. Always bootstrap context first.

## Mem0 Session Resumed
|
|
|
|
This is a resumed session. Your prior context is already loaded. Before continuing:
|
|
|
|
1. Call `search_memories` with a query related to the current task to refresh relevant memories.
|
|
2. If significant time has passed, search for recent project-wide updates.
|
|
|
|
Continue where you left off.

## Mem0 Post-Compaction Recovery
|
|
|
|
Context was just compacted. The Claude Code-generated compact summary
|
|
is being captured to mem0 in the background as `metadata.type=compact_summary`.
|
|
|
|
1. Call `search_memories` to reload context, layering up to three angles:
|
|
- `metadata.type=session_state` -- the rich pre-compaction summary you wrote
|
|
- `metadata.type=compact_summary` -- the platform-generated condensed summary just now
|
|
- `metadata.type=decision` / `anti_pattern` -- specific facts you stored during the session
|
|
2. Continue working from the recovered context.
