memory-reviewer

Memory Reviewer

Audits memory quality for the active project. Finds duplicates, contradictions, and low-confidence entries.

When to use

• User asks "check my memories", "memory quality", "any duplicates?"
• User runs /mem0:memory-reviewer directly
• After a session with 5+ memory writes (suggest proactively)
• After /mem0:health --deep identifies issues

Steps

1. Fetch all memories for active project via get_memories with filters={"AND": [{"user_id": "<active_user_id>"}, {"app_id": "<active_project_id>"}]}, page_size=200. Paginate if needed — cap at 200 memories.

2. Group by metadata.type. Common types: decision, convention, anti_pattern, task_learning, project_profile, user_preference, session_state.

3. Scan each group for issues:

Issue	Detection method
Near-duplicates	>60% noun overlap within same type. Compare memory text after stripping stop words.
Contradictions	Opposing facts about same topic (e.g., "use PostgreSQL" vs "use MySQL" for same component)
Low-confidence	metadata.confidence < 0.3
Missing type	No metadata.type set
Stale	created_at older than 180 days with no updates

1. Output compact summary:

memory-reviewer: project=<id> total=<N>
  duplicates:      <N> found
  contradictions:  <N> found
  low_confidence:  <N> found
  untagged:        <N> found
  stale:           <N> found

1. If issues found, list them with memory IDs:

Issues:
  [duplicate] "<memory_a>" ≈ "<memory_b>" [mem0:<id_a>, mem0:<id_b>]
  [contradiction] "<memory_x>" vs "<memory_y>" [mem0:<id_x>, mem0:<id_y>]
  [low_conf] "<memory_z>" (confidence: 0.1) [mem0:<id_z>]

1. Suggest action: "Run /mem0:dream to consolidate duplicates and resolve contradictions."

Constraints

• Read-only — never modify or delete memories (that's /mem0:dream's job)
• Max 200 memories per scan
• Report findings, let user decide on action
