description	Reviews stored memory quality by detecting duplicates, contradictions, and stale entries with actionable recommendations. Use when search results seem conflicting, before running dream consolidation, or for periodic memory hygiene audits.

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

4. 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

5. 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>]

6. 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
