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 namedescription- Agent descriptiontags- Agent tagsblocks- Memory blocks (if--include-blocksused)

Finding Agents by Topic
If you need to find which agent worked on a specific topic:
- Search messages across all agents:
letta messages search --query "topic" --all-agents --limit 10 - Note the
agent_idvalues from matching messages - Get agent details:
Or use the agent_id directly in the Letta APIletta agents list --query "partial-name"
