Tasks - OpenClaw Mission Control

Overview

Tasks are the fundamental work units in Mission Control. They represent actionable items that can be assigned to agents, tracked through various states, and organized with dependencies. Tasks belong to boards and flow through a defined lifecycle as agents work on them.

Data Model

From backend/app/models/tasks.py:

class Task(TenantScoped, table=True):
    id: UUID                            # Primary key
    board_id: UUID | None               # Board this task belongs to
    
    # Content
    title: str                          # Task title (required)
    description: str | None             # Detailed description (optional)
    
    # Status & Priority
    status: str                         # Current state (default: "inbox")
    priority: str                       # Urgency level (default: "medium")
    
    # Timing
    due_at: datetime | None             # Optional deadline
    in_progress_at: datetime | None     # When status changed to "in_progress"
    previous_in_progress_at: datetime | None  # Last time it was in progress
    
    # Ownership
    created_by_user_id: UUID | None     # User who created the task
    assigned_agent_id: UUID | None      # Agent currently assigned
    
    # Automation Flags
    auto_created: bool                  # Created by system (default: False)
    auto_reason: str | None             # Why it was auto-created
    
    # Timestamps
    created_at: datetime
    updated_at: datetime

Task States

Tasks progress through four primary states:

State Definitions

From backend/app/schemas/tasks.py:

TaskStatus = Literal["inbox", "in_progress", "review", "done"]

State	Description	Rules
`inbox`	Task is queued, not yet started	Default state for new tasks
`in_progress`	Agent is actively working on the task	Sets `in_progress_at` timestamp; cannot transition if blocked by dependencies
`review`	Work complete, awaiting review	Optional intermediate state before `done`
`done`	Task is complete	May require approval; reopened if dependencies change

State Transition Rules

Moving to `in_progress`

Blocked Check:

# From backend/app/api/tasks.py
blocked_by = blocked_by_dependency_ids(
    dependency_ids=dependency_task_ids,
    status_by_id=status_by_id
)

if blocked_by and (task.assigned_agent_id is not None or task.status != "inbox"):
    raise HTTPException(
        status_code=422,
        detail={
            "message": "Task is blocked by incomplete dependencies.",
            "code": "task_blocked_cannot_transition",
            "blocked_by_task_ids": [str(id) for id in blocked_by]
        }
    )

A task cannot move to in_progress if any of its dependencies are not in done state.

Moving to `done`

Approval Required: If board.require_approval_for_done is true, the task must have an approved linked approval before transitioning to done.

# From backend/app/api/tasks.py
if target_status == "done" and board.require_approval_for_done:
    approval = await get_linked_approval(task_id)
    if not approval or approval.status != "approved":
        raise HTTPException(
            status_code=422,
            detail={
                "message": "Task can only be marked done when a linked approval has been approved.",
                "code": "approval_required_for_done"
            }
        )

Review Required: If board.require_review_before_done is true, the task must transition through review state before done.

if target_status == "done" and previous_status != "review" and board.require_review_before_done:
    raise HTTPException(
        status_code=422,
        detail={
            "message": "Task can only be marked done from review when the board rule is enabled.",
            "code": "review_required_before_done"
        }
    )

Reopening Done Tasks

When a dependency task is reopened (moved from done to any other state), all dependent tasks in done state are automatically returned to inbox:

# From backend/app/api/tasks.py
reopened = previous_status == "done" and dependency_task.status != "done"

if reopened:
    dependent_tasks = await query_dependent_tasks(dependency_task_id)
    
    for dependent in dependent_tasks:
        if dependent.status == "done":
            # Return to inbox, clear progress timestamp
            dependent.status = "inbox"
            dependent.in_progress_at = None
            
            # Notify board lead
            await send_lead_notification(
                message=f"Task returned to inbox: dependency reopened ({dependency_task.title})."
            )

Task Dependencies

Tasks can depend on other tasks within the same board.

Dependency Model

From backend/app/models/task_dependencies.py:

class TaskDependency(TenantScoped, table=True):
    id: UUID                            # Primary key
    board_id: UUID                      # Board (for tenant scoping)
    task_id: UUID                       # Dependent task
    depends_on_task_id: UUID            # Blocking task
    created_at: datetime
    
    # Constraints:
    # - Unique pair (task_id, depends_on_task_id)
    # - Cannot depend on self (task_id != depends_on_task_id)

Dependency Graph

In this example:

Task 1 (done) has no dependencies
Task 2 (in_progress) depends on Task 1
Task 3 (inbox) depends on Task 2 — blocked
Task 4 (inbox) depends on Tasks 2 and 3 — blocked

Blocking Logic

From backend/app/services/task_dependencies.py:

DONE_STATUS: Final[str] = "done"

def blocked_by_dependency_ids(
    dependency_ids: Collection[UUID],
    status_by_id: Mapping[UUID, str],
) -> list[UUID]:
    """Return dependency IDs that are not yet in the done status."""
    return [
        dep_id
        for dep_id in dependency_ids
        if status_by_id.get(dep_id) != DONE_STATUS
    ]

A task is blocked if any of its dependencies are not in done state.

Creating Dependencies

POST /api/v1/tasks/{task_id}/dependencies
Authorization: Bearer <token>

{
  "depends_on_task_id": "<blocking-task-uuid>"
}

Alternatively, specify dependencies when creating a task:

POST /api/v1/tasks
Authorization: Bearer <token>

{
  "title": "Implement feature",
  "board_id": "<board-uuid>",
  "depends_on_task_ids": [
    "<task-1-uuid>",
    "<task-2-uuid>"
  ]
}

Task Assignment

Tasks can be assigned to agents for execution.

Assigning Agents

PATCH /api/v1/tasks/{task_id}
Authorization: Bearer <token>

{
  "assigned_agent_id": "<agent-uuid>"
}

Or use the dedicated assignment endpoint:

POST /api/v1/tasks/{task_id}/assign-agent
Authorization: Bearer <token>

{
  "agent_id": "<agent-uuid>"
}

Assignment Rules

Board Scope: Agent must belong to the same board as the task
Agent Status: Agent must be in ready, active, or idle state (not provisioning, paused, or deleted)
Capacity: Board’s max_agents limit is enforced at provisioning time, not assignment time

Auto-Assignment

Board lead agents can implement auto-assignment logic by:

Querying unassigned tasks: GET /api/v1/agent/boards/{board_id}/tasks?assigned_agent_id=null
Selecting appropriate worker agents: GET /api/v1/agent/boards/{board_id}/agents
Updating task assignments: PATCH /api/v1/agent/boards/{board_id}/tasks/{task_id}

Task Priority

Priority is a string field with common values:

low
medium (default)
high
urgent

Priority is informational; Mission Control does not enforce any ordering based on priority. Agents can query tasks filtered or sorted by priority to implement their own prioritization logic.

Task Metadata

Custom Fields

Boards can define custom fields for tasks:

PATCH /api/v1/tasks/{task_id}
Authorization: Bearer <token>

{
  "custom_field_values": {
    "severity": "critical",
    "customer_impact": "high",
    "estimated_hours": 8
  }
}

Custom fields are defined at the organization level and can be attached to specific boards.

Task Comments

Agents and users can add comments to tasks:

POST /api/v1/tasks/{task_id}/comments
Authorization: Bearer <token>

{
  "message": "Work in progress, encountered blocker with API integration."
}

Or include a comment with a task update:

PATCH /api/v1/tasks/{task_id}
Authorization: Bearer <token>

{
  "status": "in_progress",
  "comment": "Starting work on this task."
}

Task Read Model

From backend/app/schemas/tasks.py:

class TaskRead(TaskBase):
    id: UUID
    board_id: UUID | None
    created_by_user_id: UUID | None
    in_progress_at: datetime | None
    created_at: datetime
    updated_at: datetime
    
    # Computed fields
    blocked_by_task_ids: list[UUID] = Field(default_factory=list)
    is_blocked: bool = False
    
    # Metadata
    tags: list[TagRef] = Field(default_factory=list)
    custom_field_values: dict | None = None

The blocked_by_task_ids field is computed at read time by querying dependencies and checking their status.

Task Management

GET /api/v1/tasks — List all tasks (with filters)
POST /api/v1/tasks — Create task
GET /api/v1/tasks/{id} — Get task details
PATCH /api/v1/tasks/{id} — Update task
DELETE /api/v1/tasks/{id} — Delete task
GET /api/v1/tasks/stream — SSE stream of task updates

Board Tasks

GET /api/v1/boards/{board_id}/tasks — List tasks for a board

Dependencies

GET /api/v1/tasks/{id}/dependencies — List task dependencies
POST /api/v1/tasks/{id}/dependencies — Create dependency
DELETE /api/v1/tasks/{task_id}/dependencies/{dependency_id} — Remove dependency

Comments

GET /api/v1/tasks/{id}/comments — List task comments
POST /api/v1/tasks/{id}/comments — Add comment

Assignment

POST /api/v1/tasks/{id}/assign-agent — Assign agent to task

Agent Endpoints (require `X-Agent-Token`)

GET /api/v1/agent/boards/{board_id}/tasks — Get tasks for board
PATCH /api/v1/agent/boards/{board_id}/tasks/{task_id} — Update task
POST /api/v1/agent/boards/{board_id}/tasks/{task_id}/comments — Add comment

Query Filters

The task list endpoint supports extensive filtering:

GET /api/v1/tasks?
  board_id=<uuid>&
  status=in_progress&
  status=review&
  assigned_agent_id=<uuid>&
  created_by_user_id=<uuid>&
  priority=high&
  tag_ids=<uuid>&
  include_done=false&
  limit=50&
  offset=0

Common Query Patterns

Unassigned tasks:

GET /api/v1/tasks?board_id=<uuid>&assigned_agent_id=null&status=inbox

Active work:

GET /api/v1/tasks?board_id=<uuid>&status=in_progress

Overdue tasks:

GET /api/v1/tasks?board_id=<uuid>&due_before=2026-03-05T00:00:00Z&status=inbox&status=in_progress

Blocked tasks:

GET /api/v1/tasks?board_id=<uuid>&is_blocked=true

Board Rules

Boards can enforce workflow rules that affect task transitions:

Approval Rules

class Board:
    require_approval_for_done: bool = True        # Require approval link
    require_review_before_done: bool = False      # Must go through review
    block_status_changes_with_pending_approval: bool = True  # Lock during approval

See backend/app/models/boards.py for full board configuration.

Lead-Only Status Changes

class Board:
    only_lead_can_change_status: bool = False

When true, only the board lead agent can change task status. Worker agents can still add comments and update other fields.

Metrics

Task metrics are available for boards and board groups:

GET /api/v1/metrics/boards/{board_id}

Response:

{
  "board_id": "70a4ea4f-...",
  "task_counts": {
    "inbox": 5,
    "in_progress": 3,
    "review": 1,
    "done": 12
  },
  "tasks_by_agent": {
    "c91361ef-...": 2,
    "e595d5d1-...": 1
  },
  "overdue_count": 1,
  "blocked_count": 2
}

Activity Feed

Task changes are logged to the activity feed:

GET /api/v1/activity?board_id=<uuid>

Events include:

task.created
task.updated (with field diff)
task.status_changed
task.assigned
task.commented
task.dependency_added
task.dependency_removed

Real-Time Updates

Subscribe to task changes via Server-Sent Events:

GET /api/v1/tasks/stream?board_id=<uuid>
Authorization: Bearer <token>

Stream format:

event: task.updated
data: {"task": {...}, "changes": {...}}

event: task.status_changed
data: {"task": {...}, "previous_status": "inbox", "new_status": "in_progress"}
