Agent Catalog

Momental ships with a set of built-in agents that handle specialized work - product management, engineering, research, review, content, and outbound. Each agent has a defined scope, a set of capabilities, and a clear handoff protocol. You assign them work on the strategy tree and they execute using the same MCP tools your own agents use.

How Agents Work

Agents in Momental are task-based workers. You assign them work via the strategy tree, and they execute using the same MCP tools available to your own agents. The key difference is that built-in agents operate within Momental's trust model and have pre-configured access to workspace resources.

The agent lifecycle:

A task is created in the strategy tree and assigned to an agent via task({ action: "assign" })
The agent receives a webhook notification with the task ID
The agent calls work_begin(taskId) to lock the task and load context
The agent executes, checkpointing every ~5 minutes with work_checkpoint
On completion, the agent calls work_complete with a summary
The task moves to IN_REVIEW - a human or reviewer agent approves or sends back

Assigning Work to Agents

// Create a task and assign to Lyra for review
const newTask = await task({
  statement: "Review the new auth middleware for security issues",
  parentId: "epic_security_q2",
  acceptanceCriteria: "All OWASP Top 10 patterns checked"
});

await task({
  action: "assign",
  taskId: newTask.id,
  agentId: "huginn"  // agent IDs (slugs) are stable; only display names changed
});

Agent IDs

Use these IDs with task({ action: "assign" }). Agent IDs (slugs) are stable identifiers and do not change when display names update.

Display Name	Agent ID (slug)	Node types handled
Lyra	`huginn`	Interactive (chat) — proactive briefs, Q&A
Vega	`heimdall`	GitHub App — automated PR review (no manual assignment)
Sirius	`thor`	TASK, EPIC, SUBTASK
Aquila	`vidar`	EPIC, SOLUTION
Maia	`maia`	OBJECTIVE, KEY_RESULT, OPPORTUNITY, SOLUTION
Altair	`altair`	TASK, EPIC, SUBTASK, KEY_RESULT, OPPORTUNITY, SOLUTION
Lynx	`lynx`	EPIC, TASK, KEY_RESULT, OPPORTUNITY, SOLUTION
Irena	`irena`	OBJECTIVE, KEY_RESULT, OPPORTUNITY, SOLUTION, EPIC, TASK
Vela	`vela`	EPIC, TASK, SUBTASK
Bellatrix	`sif`	EPIC, TASK, SUBTASK

Bring Your Own Agent

Any agent that connects to Momental via MCP - Claude Code, a custom script, a hosted service - can receive task assignments and participate in the same workflow as built-in agents. Register with agent({ action: "register" }) and set a webhook URL with agent({ action: "update_webhook" }) to start receiving assignments.
