List tasks from Delega, optionally filtered by project, label, due date, or completion status

Get full details of a specific task including subtasks

Create a new task in Delega

Update an existing task's fields

Assign a task to an agent (or unassign by passing null)

Delegate a task: create a child task linked to a parent. The parent's status flips to 'delegated'. Use this (not assign_task) for multi-agent handoffs so the delegation chain is recorded.

Get the full delegation chain for a task (root + all descendants, sorted by depth). Use this to inspect parent/child accountability.

Merge keys into a task's persistent context blob. Existing keys are preserved; supplied keys are added or overwritten. Use this to pass shared state between delegated agents instead of re-describing context in task descriptions.

Check whether a proposed task is similar to existing open tasks (Jaccard similarity). Call this before create_task to avoid redundant work.

Get quota and rate-limit information for the current plan. Hosted API only (api.delega.dev) — self-hosted deployments will receive a clear error.

Mark a task as completed

Delete a task permanently

Add a comment to a task

List all projects in Delega

Get task statistics from Delega (totals, completed today, due today, overdue, by project)

List all registered agents in Delega

Register a new agent in Delega. Returns the API key (shown only at creation — save it!)

Delete an agent. The API may refuse if the agent has active tasks or is the last active agent.

List all webhooks configured for your account (admin only)

Create a webhook to receive event notifications (admin only). Events: task.created, task.updated, task.completed, task.deleted, task.assigned, task.commented

Delete a webhook by ID (admin only)
