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

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.

Group by
metadata.type
. Common types:

decision

,

convention

,

anti_pattern

,

task_learning

,

project_profile

,

user_preference

,

session_state

.

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

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

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>]

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
