Finding Agents

This skill helps you find other agents on the same Letta server.

When to Use This Skill

• User asks about other agents they have
• User wants to find a specific agent by name
• User wants to list agents with certain tags
• You need to find an agent ID for memory migration
• You found an agent_id via message search and need details about that agent

CLI Usage

letta agents list [options]

Options

| Option | Description | |--------|-------------| | --name <name> | Exact name match | | --query <text> | Fuzzy search by name | | --tags <tag1,tag2> | Filter by tags (comma-separated) | | --match-all-tags | Require ALL tags (default: ANY) | | --include-blocks | Include agent.blocks in response | | --limit <n> | Max results (default: 20) |

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)

Related Skills

• migrating-memory - Once you find an agent, use this skill to copy/share memory blocks
• searching-messages - Search messages across all agents to find which agent discussed a topic. Use --all-agents to get agent_id values, then use this skill to get full agent details.

Finding Agents by Topic

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

1. Load both skills: searching-messages and finding-agents
2. Search messages across all agents:

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

3. Note the agent_id values from matching messages
4. Get agent details:

   letta agents list --query "partial-name"
   

   Or use the agent_id directly in the Letta API
