name: cognee-remember description: Store data permanently in the Cognee knowledge graph. Accepts a data category (user, project, or agent) to tag the data with the correct node_set for filtered retrieval.

Cognee Permanent Memory Storage

Store data permanently in the Cognee knowledge graph with category tagging.

Data categories

Cognee organizes knowledge into three categories via node_set tagging:

Instructions

Determine the category from the user's intent, then run:

User data (preferences, corrections, personal context):

cognee-cli remember "$ARGUMENTS" -d "${COGNEE_PLUGIN_DATASET:-claude_sessions}" --node-set user_context

Project data (docs, code, company knowledge):

cognee-cli remember "$ARGUMENTS" -d "${COGNEE_PLUGIN_DATASET:-claude_sessions}" --node-set project_docs

Agent data (explicit agent notes — routine tool logs are automatic):

cognee-cli remember "$ARGUMENTS" -d "${COGNEE_PLUGIN_DATASET:-claude_sessions}" --node-set agent_actions

If the category is unclear, default to project.

The command outputs a summary after completion:

Data ingested and knowledge graph built successfully!
  Dataset ID: aaaaaaaa-bbbb-cccc-dddd-eeeeeeeeeeee
  Items processed: 1
  Content hash: a1b2c3d4...
  Elapsed: 4.2s

IMPORTANT: Do NOT use the -b (background) flag. Always run in the foreground to ensure the full pipeline completes.

When to use

• User says "remember this" or "save this" → category user
• User says "remember this about the project/codebase" → category project
• You want to persist your own findings or conclusions → category agent
• NOT for routine tool call logging (that's automatic via hooks with agent_actions tagging)
