Common Patterns

Finding Letta Code Agents

Agents created by Letta Code are tagged with origin:letta-code. To find only Letta Code agents:

letta agents list --tags "origin:letta-code"

This is useful when the user is looking for agents they've worked with in Letta Code CLI sessions.

Finding All Agents

If the user has agents created outside Letta Code (via ADE, SDK, etc.), search without the tag filter:

letta agents list

Examples

List all agents (up to 20):

letta agents list

Find agent by exact name:

letta agents list --name "ProjectX-v1"

Search agents by name (fuzzy):

letta agents list --query "project"

Find only Letta Code agents:

letta agents list --tags "origin:letta-code"

Find agents with multiple tags:

letta agents list --tags "frontend,production" --match-all-tags

Include memory blocks in results:

letta agents list --query "project" --include-blocks

Output

Returns the raw API response with full agent details. Key fields:

• id - Agent ID (e.g., agent-abc123)
• name - Agent name
• description - Agent description
• tags - Agent tags
• blocks - Memory blocks (if --include-blocks used)

Finding Agents by Topic

If you need to find which agent worked on a specific topic:

1. Search messages across all agents:

``bash letta messages search --query "topic" --all-agents --limit 10 ``

1. Note the agent_id values from matching messages
2. Get agent details:

``bash letta agents list --query "partial-name" `` Or use the agent_id directly in the Letta API
