Allow tasks to be assigned to AI agents (Page AI) in addition to human users. This enables AI agents to have assigned responsibilities and coordinate work with each other.

Changes:

  • Add assigneeAgentId field to task_items table with foreign key to pages
  • Update task API routes to handle agent assignees alongside user assignees
  • Create /api/drives/[driveId]/assignees endpoint returning both members and agents
  • Redesign AssigneeSelect component to show grouped members and agents
  • Update AI update_task tool with assigneeAgentId parameter
  • Add get_assigned_tasks tool for agents to query their assigned tasks
  • Agents can assign tasks to themselves or other agents via tool calls

178-236: Add validation for assigneeAgentId in task creation.

Similar to the PATCH endpoint issue, the POST endpoint should validate that assigneeAgentId:

  1. References a valid AI_CHAT page
  2. Belongs to the same drive as the task being created
🔎 Suggested validation logic

Add validation after line 195 (after getting the task list):

  // Get or create task list
  const taskList = await getOrCreateTaskListForPage(pageId, userId);
+
+ // Validate assigneeAgentId if provided
+ if (assigneeAgentId) {
+   const agent = await db.query.pages.findFirst({
+     where: and(
+       eq(pages.id, assigneeAgentId),
+       eq(pages.type, 'AI_CHAT'),
+       eq(pages.isTrashed, false)
+     ),
+     columns: { id: true, driveId: true },
+   });
+
+   if (!agent) {
+     return NextResponse.json(
+       { error: 'Invalid agent ID' },
+       { status: 400 }
+     );
+   }
+
+   if (agent.driveId !== taskListPage.driveId) {
+     return NextResponse.json(
+       { error: 'Agent must be in the same drive as the task' },
+       { status: 400 }
+     );
+   }
+ }
🧹 Nitpick comments (4)
apps/web/src/app/api/drives/[driveId]/assignees/route.ts (1)

78-85: Optimize permission checking for better performance.

The sequential loop with await canUserViewPage() can be slow when there are many agents. Consider using Promise.all() for concurrent permission checks.

🔎 Proposed optimization
- // Filter agents by view permissions
- const accessibleAgents: { id: string; title: string | null }[] = [];
- for (const agent of allAgents) {
-   const canView = await canUserViewPage(userId, agent.id);
-   if (canView) {
-     accessibleAgents.push(agent);
-   }
- }
+ // Filter agents by view permissions (concurrent checks)
+ const permissionChecks = await Promise.all(
+   allAgents.map(async (agent) => ({
+     agent,
+     canView: await canUserViewPage(userId, agent.id),
+   }))
+ );
+ 
+ const accessibleAgents = permissionChecks
+   .filter(({ canView }) => canView)
+   .map(({ agent }) => agent);
apps/web/src/lib/ai/tools/task-management-tools.ts (2)

3-3: Unused imports: or and isNull are imported but never used.

The imports or and isNull from @pagespace/db are not used anywhere in the file. The query conditions use and, eq, not, but neither or nor isNull.

🔎 Proposed fix
-import { db, taskLists, taskItems, pages, eq, and, desc, asc, or, isNull, not } from '@pagespace/db';
+import { db, taskLists, taskItems, pages, eq, and, desc, asc, not } from '@pagespace/db';

511-516: Consider filtering by driveId at the database level for better performance.

The driveId filter is applied post-query in JavaScript (line 514), which means all tasks assigned to the agent are fetched before filtering. For agents with many tasks across drives, this could be inefficient.

Since the query already includes taskList.page relation (lines 497-499), you could add a subquery condition or use a more complex join to filter at the database level. However, this adds complexity.

For now, this approach is acceptable if task volumes are low. Consider optimizing if performance becomes an issue with large task counts.

apps/web/src/components/layout/middle-content/page-views/task-list/AssigneeSelect.tsx (1)

45-49: Consider documenting the onSelect callback signature.

The onSelect callback has a non-trivial signature with three parameters. A brief JSDoc comment explaining the expected behavior would help consumers understand:

  • When a user is selected: userId is set, agentId is null
  • When an agent is selected: userId is null, agentId is set
  • When unassigning: all parameters are null

packages/db/drizzle/0032_misty_goblin_queen.sql (1)

1-8: LGTM!

The migration is well-structured with proper idempotent constraint creation and appropriate indexing. The foreign key constraint uses ON DELETE SET NULL, which is correct for optional assignee relationships.

apps/web/src/components/ai/shared/chat/ExpandableTaskItem.tsx (1)

105-123: Clarify assignment behavior: mutual exclusivity vs dual assignment.

The implementation clears the user assignee when an agent is assigned (Line 113), enforcing mutual exclusivity. However, the schema comments in packages/db/src/schema/tasks.ts (lines 35-38) state: "A task can have both a user and agent assignee."

Please clarify the intended behavior:

  • If mutual exclusivity is intentional, update the schema comments to reflect this.
  • If dual assignment should be supported, modify this logic to preserve both assignees.
packages/db/drizzle/meta/_journal.json (1)

229-235: LGTM!

Journal entry correctly records the migration metadata.

apps/web/src/app/api/pages/[pageId]/tasks/[taskId]/route.ts (1)

183-189: LGTM!

The assigneeAgent relation fetch is correctly implemented, following the pattern of existing relations.

packages/db/src/schema/tasks.ts (2)

34-45: LGTM!

The schema extension is well-documented with clear comments explaining the dual assignment model (user and agent). The column definition with foreign key to pages.id and ON DELETE SET NULL is appropriate.


98-107: LGTM!

The relations are properly defined with appropriate relation names to avoid conflicts. The assignedAgent and taskPage relation names provide clarity.

apps/web/src/app/api/drives/[driveId]/assignees/route.ts (1)

87-111: LGTM!

The unified assignee list construction is clean and follows a consistent pattern for both users and agents. The normalization of fields (id, type, name, image) provides a good API surface for consumers.

apps/web/src/app/api/pages/[pageId]/tasks/route.ts (2)

78-105: LGTM!

The GET endpoint correctly includes assigneeAgentId in the query columns and fetches the assigneeAgent relation with appropriate fields.


254-260: LGTM!

The assigneeAgent relation is correctly included in the POST response, maintaining consistency with the GET endpoint.

apps/web/src/components/layout/middle-content/page-views/task-list/TaskListView.tsx (5)

73-104: LGTM!

The TaskItem interface extension properly includes both assigneeAgentId and the assigneeAgent relation object, maintaining type consistency with the API responses.


147-147: LGTM!

The signature update to include agentId maintains consistency across mobile and desktop views.


304-310: LGTM!

The mobile view correctly passes both currentAssignee and currentAssigneeAgent to the AssigneeSelect, and the onSelect callback properly handles both user and agent assignments.


559-572: LGTM!

The handleAssigneeChange function correctly accepts both assigneeId and agentId, then sends both values to the API via the PATCH request. This properly implements the dual-assignment capability at the API layer.


898-904: LGTM!

The desktop table view mirrors the mobile implementation, correctly passing both assignee types to the AssigneeSelect component.

apps/web/src/lib/ai/tools/task-management-tools.ts (3)

67-68: Consider validating that assigneeAgentId references a valid AI_CHAT page.

The update_task tool accepts any string for assigneeAgentId without validating that it references an actual AI agent (page with type AI_CHAT). In contrast, get_assigned_tasks validates the agent exists and is of type AI_CHAT (lines 459-466). Consider adding similar validation in update_task when assigneeAgentId is provided to fail fast with a clear error message.

This could be intentional if validation happens elsewhere or if you prefer loose coupling. Verify whether the database foreign key constraint to pages.id is sufficient for your use case, or if type validation is needed at the application layer.


134-135: LGTM!

The assigneeAgentId handling in the update path correctly mirrors the existing assigneeId pattern, and the create path (line 270) is consistent. The response includes both the assigneeAgentId field and the assigneeAgent relation data.


419-434: LGTM!

The get_assigned_tasks tool is well-designed:

  • Clear description for AI consumption
  • Smart default behavior using agentChain context (lines 448-452)
  • Proper validation of agent existence and type (AI_CHAT)
  • Appropriate permission check using canUserViewPage
  • Useful summary grouping by status
apps/web/src/components/layout/middle-content/page-views/task-list/AssigneeSelect.tsx (4)

25-31: LGTM!

The Assignee interface with a discriminated type field is a clean approach for handling both users and agents uniformly. This aligns well with the API response structure from /api/drives/[driveId]/assignees.


78-82: Clarify behavior when both currentAssignee and currentAssigneeAgent are provided.

The logic prioritizes currentAssigneeAgent over currentAssignee when both are present (line 82). If a task can have both a user and agent assigned simultaneously, the UI will only show the agent as selected, which may confuse users.

Verify the intended UX:

  1. Can a task have both a user and agent assignee simultaneously?
  2. If yes, should the UI indicate both, or is showing only the agent correct?
  3. If no, consider adding a runtime check or TypeScript constraint to prevent both being set.

175-227: LGTM!

The UI implementation is well-structured:

  • Clear visual distinction between users (avatars) and agents (Bot icon)
  • Proper use of CommandSeparator and CommandGroup with headings
  • Unique key and value prefixes prevent collisions
  • Conditional rendering of sections only when items exist

This follows Tailwind CSS and shadcn/ui patterns as per coding guidelines.


68-72: LGTM!

SWR configuration follows coding guidelines with revalidateOnFocus: false. The conditional key pattern (driveId ? url : null) correctly prevents fetching when driveId is not available.

53-59: Consider clarifying the unassignment instruction.

The phrase "Set both to null to unassign" (line 59) might be misread as requiring both fields to be null simultaneously. Since assigneeId and assigneeAgentId are independent, consider: "Set to null to unassign" or "Set either or both to null to unassign the respective assignee."

apps/web/src/lib/ai/tools/task-management-tools.ts (4)

3-3: LGTM!

The import additions are necessary and correctly used: not for query filtering (line 486) and canUserViewPage for permission checks (line 472).

Also applies to: 6-6


74-74: LGTM!

The assigneeAgentId parameter is properly threaded through the execution flow: extracted from params, propagated to update operations, and persisted on task creation. The implementation correctly handles null values for unassignment.

Also applies to: 135-135, 270-270


334-340: LGTM!

The response payload correctly includes both assigneeAgentId and the full assigneeAgent relation data. The pattern mirrors the existing assignee/assigneeId structure, ensuring consistent API design.

Also applies to: 369-369, 390-390, 400-404


477-566: LGTM on query construction and response formatting!

The query logic correctly uses the not operator to exclude completed tasks (line 486), properly fetches all necessary relations, and formats the response with helpful grouping by status. The renaming of assignee to userAssignee (lines 555-558) improves clarity when distinguishing between human and agent assignees.

Note: The security concern about drive-level permissions has been flagged separately in the previous comment.

10-17: Consider exporting the Assignee interface for type consistency.

The Assignee interface defines the public API contract. If consumers (like the UI components mentioned in the summary) need to type-check against this interface, consider exporting it or defining it in a shared types module.


124-130: Avoid leaking internal error details in production.

The error message includes the raw error content, which could expose internal details. Consider using a generic message in production or sanitizing the error.

🔎 Suggested approach
   } catch (error) {
     console.error('Error fetching assignees:', error);
     return NextResponse.json(
-      { error: `Failed to fetch assignees: ${error instanceof Error ? error.message : String(error)}` },
+      { error: 'Failed to fetch assignees' },
       { status: 500 }

apps/web/src/app/api/pages/[pageId]/tasks/[taskId]/route.ts (3)

54-54: LGTM!

Properly destructures assigneeAgentId from the request body alongside other task fields.


94-121: Good implementation of assigneeAgentId validation.

The validation correctly ensures that:

  1. The agent page exists and is of type AI_CHAT
  2. The agent page is not trashed
  3. The agent belongs to the same drive as the task list

This addresses the security concern from previous reviews. One minor observation: on line 116, the null check if (taskListPage && ...) is defensive but taskListPage should always exist at this point since it's fetched unconditionally on lines 95-98.


202-208: LGTM!

The assigneeAgent relation is properly included in the task fetch with the appropriate columns (id, title, type), consistent with the pattern used elsewhere in the codebase.

apps/web/src/app/api/pages/[pageId]/tasks/route.ts (6)

78-78: LGTM!

The assigneeAgentId column is properly added to the GET query response.


99-105: LGTM!

The assigneeAgent relation is correctly included with consistent column selection (id, title, type), matching the pattern used in other task queries throughout the codebase.


178-178: LGTM!

Properly destructures assigneeAgentId from the request body for task creation.


194-212: Good validation implementation.

The validation logic mirrors the PATCH endpoint and correctly ensures:

  1. The agent exists and is of type AI_CHAT
  2. The agent is not trashed
  3. The agent belongs to the same drive as the task list

Note: Unlike the PATCH route where the drive comparison uses a defensive null check (if (taskListPage && ...)), this implementation directly compares agentPage.driveId !== taskListPage.driveId because taskListPage is guaranteed to exist (404 is returned on line 191 if missing). This is the correct approach.


255-255: LGTM!

The assigneeAgentId is correctly persisted when creating a new task.


274-280: LGTM!

The assigneeAgent relation is properly included in the response for newly created tasks.

apps/web/src/app/api/drives/[driveId]/assignees/route.ts (3)

23-41: LGTM!

Follows Next.js 15 patterns correctly:

  • Awaits context.params before destructuring
  • Uses centralized permission function getUserDriveAccess
  • Returns proper 403 response for access denial

44-62: LGTM!

Clean query construction joining driveMembers with users and userProfiles to build the member list with fallback display names.


78-87: Good use of parallel permission checks.

Using Promise.all for parallel permission checks is a sensible optimization. For drives with many agents, this could still generate N permission queries. Consider documenting this as a known performance characteristic if agent counts grow significantly.

apps/web/src/lib/ai/tools/task-management-tools.ts (10)

3-3: LGTM!

The not operator is correctly imported for use in the status filter query.


6-6: LGTM!

Imports are updated to include the necessary permission functions from @pagespace/lib/server.


43-59: LGTM!

Tool description is well-documented with clear guidance on using assigneeId vs assigneeAgentId and explains that agents can assign tasks to themselves or other agents.


67-68: LGTM!

The assigneeAgentId schema field is properly defined with nullable support and a clear description.


334-340: LGTM!

The response structure properly includes assigneeAgent details and assigneeAgentId in all relevant places, providing consistent data for consumers.

Also applies to: 369-369, 390-390, 400-404


419-433: LGTM!

The tool description and input schema are well-defined. Note that line 433 correctly uses .default(false) without redundant .optional(), addressing the past review feedback about Zod 4 patterns.


444-456: LGTM!

Good implementation of agent ID resolution from the agentChain context when no explicit agentId is provided. This enables agents to query their own tasks naturally.


458-475: LGTM!

Properly validates that the target agent exists and the user has view permission before proceeding.


511-539: Good security implementation addressing past review concerns.

This correctly addresses the security concern from the past review by:

  1. Collecting unique drive IDs from tasks (lines 512-516)
  2. Checking drive access in parallel (lines 519-524)
  3. Filtering out tasks from inaccessible drives (line 535)

This prevents cross-drive data leakage while maintaining reasonable performance with parallel permission checks.


541-584: LGTM!

Clean implementation of task grouping by status with a well-structured response including agent info, summary counts, and detailed task data.

⚠️ Potential issue | 🟠 Major

Missing validation for assigneeAgentId in the update path.

The API routes (PATCH /api/pages/[pageId]/tasks/[taskId]) validate that assigneeAgentId references a valid AI_CHAT page in the same drive. However, this tool bypasses those validations by directly updating the database.

This could allow agents to assign tasks to:

  1. Non-existent pages
  2. Pages that aren't AI agents (non-AI_CHAT type)
  3. Agents in different drives (cross-drive assignment)
🔎 Suggested validation

Add validation before setting updateData.assigneeAgentId:

if (assigneeAgentId !== undefined) {
  if (assigneeAgentId) {
    // Get task list's driveId for validation
    let taskListDriveId: string | undefined;
    if (taskList.pageId) {
      const tlPage = await db.query.pages.findFirst({
        where: eq(pages.id, taskList.pageId),
        columns: { driveId: true },
      });
      taskListDriveId = tlPage?.driveId;
    }

    const agentPage = await db.query.pages.findFirst({
      where: and(
        eq(pages.id, assigneeAgentId),
        eq(pages.type, 'AI_CHAT'),
        eq(pages.isTrashed, false)
      ),
      columns: { id: true, driveId: true },
    });

    if (!agentPage) {
      throw new Error('Invalid agent ID - must be an AI agent page');
    }

    if (taskListDriveId && agentPage.driveId !== taskListDriveId) {
      throw new Error('Agent must be in the same drive as the task list');
    }
  }
  updateData.assigneeAgentId = assigneeAgentId;
}
🤖 Prompt for AI Agents
In apps/web/src/lib/ai/tools/task-management-tools.ts around line 135, the
patch/update path sets updateData.assigneeAgentId without validating the
provided assigneeAgentId; add validation to ensure it references an existing,
non-trashed page of type 'AI_CHAT' and that, if the task list has a
page/driveId, the agent's page.driveId matches that driveId; specifically, when
assigneeAgentId is not undefined and non-empty, query pages to fetch the task
list's driveId (if taskList.pageId exists), then query pages for the candidate
agent with id = assigneeAgentId, type = 'AI_CHAT', isTrashed = false returning
id and driveId, throw a descriptive Error if the agent page is missing or if its
driveId differs from the taskList driveId, and only then set
updateData.assigneeAgentId.

- Fix counts.members to use actual filtered count (exclude null users)
- Add assigneeAgentId validation to AI tool update path
- Add assigneeAgentId validation to AI tool create path
  - Must be a valid AI_CHAT page
  - Must be in the same drive as the task list

136-153: Consider extracting agent validation to a helper function.

The assigneeAgentId validation logic is duplicated between update (lines 136-153) and create (lines 277-295) paths. A shared helper could reduce duplication:

🔎 Optional refactor
async function validateAgentAssignment(
  assigneeAgentId: string,
  targetDriveId: string
): Promise<void> {
  const agentPage = await db.query.pages.findFirst({
    where: and(
      eq(pages.id, assigneeAgentId),
      eq(pages.type, 'AI_CHAT'),
      eq(pages.isTrashed, false)
    ),
    columns: { id: true, driveId: true },
  });

  if (!agentPage) {
    throw new Error('Invalid agent ID - must be an AI agent page');
  }

  if (agentPage.driveId !== targetDriveId) {
    throw new Error('Agent must be in the same drive as the task list');

1-7: LGTM!

Imports are correctly organized, using the centralized @pagespace/db and @pagespace/lib/server packages as per coding guidelines.


125-165: Validation for assigneeAgentId correctly implemented.

The validation properly:

  • Verifies the agent is an AI_CHAT page that isn't trashed
  • Ensures same-drive constraint when taskListDriveId exists
  • Allows null for unassignment via the !== undefined check on line 165

This addresses the previous review feedback.


277-295: Create path validation is correctly implemented.

The validation mirrors the update path and correctly enforces same-drive constraint against taskListPage.driveId.


384-455: LGTM!

Response shape correctly includes assigneeAgentId and assigneeAgent details with consistent null handling.


479-484: Zod schema follows idiomatic patterns.

The includeCompleted parameter correctly uses .default(false) without the redundant .optional(), addressing previous feedback.


561-589: Security concern properly addressed.

The implementation now correctly:

  • Extracts unique drive IDs from fetched tasks
  • Checks drive access in parallel using getUserDriveAccess
  • Filters out tasks from drives the user cannot access
  • Excludes tasks with trashed pages

This comprehensively addresses the previous security feedback about cross-drive task leakage.


494-506: Agent chain resolution is well-implemented.

The logic correctly derives the current agent from the last element of agentChain, aligning with the ToolExecutionContext type definition where agentChain is [rootAgentId, ...intermediates, currentAgentId].


635-638: LGTM!

Error handling follows the same pattern as update_task with proper logging and contextual error messages.
