      operationId: createChecklistItems
      x-ai-role: project_management_specialist
      x-ai-description: Adds one or more actionable items to an existing checklist, extending its task structure. In SendPulse CRM, checklist items are the atomic units of work tracking within a checklist — each represents a discrete task with a completion state. This endpoint is used to populate a newly created checklist or extend an existing one with additional steps.
      x-ai-reasoning-instructions:
      - Verify the target checklist exists before attempting to add items; use the checklist retrieval endpoint if the ID is uncertain.
      - If the user provides a list of tasks to add, batch them into a single request where the API supports arrays, or iterate sequentially.
      - When `isDone` is not specified, default to 0 (not completed) — do not assume a task is pre-completed unless explicitly stated.
      - Check whether the checklist already contains an item with the same name to avoid duplicate entries.
      x-ai-responding-instructions:
      - Confirm successful creation by reporting the new item's ID and name.
      - 'If `isDone: 1` was passed, note that the item was created already marked as completed.'
      - Suggest marking items done via the update endpoint once the corresponding task is finished.
      - On error, clarify whether the issue is a missing checklist (invalid `checklistId`) or a validation problem with the item payload.
      x-ai-suggestions:
      - Send follow-up email to client
      - Prepare contract draft
      - Schedule kick-off call
      - Review proposal

      operationId: reorderChecklistItem
      x-ai-role: project_management_specialist
      x-ai-description: Reorders a specific item within a checklist by updating its position index. Ordering affects how items are displayed and prioritized in task views — use this when automating task sequencing or responding to user-driven drag-and-drop reordering.
      x-ai-reasoning-instructions:
      - Verify that both checklistId and itemId exist before attempting reorder to avoid silent failures.
      - Check the current item order before submitting to avoid redundant requests if the item is already in the desired position.
      - Consider whether other items' positions will shift automatically or require explicit updates — clarify with the user if sequencing is critical.
      x-ai-responding-instructions:
      - Confirm the item was moved to the requested position.
      - If the order value conflicts with existing items, explain how the system resolves the conflict (shift vs. override).
      - Suggest retrieving the updated checklist to verify the new item sequence.
      x-ai-suggestions:
      - 'Use order: 1 to promote the item to the top of the checklist.'
      - After reordering, call getChecklist to confirm the updated item sequence.

      operationId: updateChecklistItem
      x-ai-role: task_management_specialist
      x-ai-description: Updates the state or label of a specific item within a checklist. This endpoint is the primary mechanism for tracking task completion — toggling `isDone` marks progress without deleting history. Used by agents to reflect real-time workflow status changes driven by user actions or automation triggers.
      x-ai-reasoning-instructions:
      - Verify that both `checklistId` and `itemId` exist before sending the request to avoid cryptic 404 errors.
      - When toggling `isDone`, treat 1 as 'completed' and 0 as 'reopened' — communicate the semantic difference to the user clearly.
      - If only renaming the item, omit `isDone` from the payload to avoid unintentional state changes.
      - If the user wants to mark multiple items done, issue sequential calls — there is no bulk-update endpoint.
      x-ai-responding-instructions:
      - Confirm which field was changed (name, status, or both) and reflect the new value in the response summary.
      - If `isDone` was set to 1, acknowledge the task as completed and suggest reviewing remaining items in the checklist.
      - If `isDone` was set to 0, frame it as the task being reopened or reset for further work.
      - Highlight the returned `id` to confirm the correct item was updated.
      x-ai-suggestions:
      - 'Mark item as done: set `isDone: 1`'
      - 'Reopen item: set `isDone: 0`'
      - 'Rename item without changing status: send only `name`'

      operationId: deleteChecklistItem
      x-ai-role: task_management_specialist
      x-ai-description: Permanently removes a single item from a checklist by its ID. This is an irreversible destructive operation — the item and any associated state (completion status, notes) are deleted immediately. Use when the task is no longer relevant or was added by mistake.
      x-ai-reasoning-instructions:
      - Confirm the correct itemId before deletion — there is no undo.
      - If the user refers to an item by name or description rather than ID, resolve the ID first via the list items endpoint.
      - Check whether the item is the last one in the checklist; deleting it may leave an empty checklist.
      x-ai-responding-instructions:
      - Confirm the deletion succeeded (204 No Content means success).
      - Do not attempt to display the deleted item — it no longer exists.
      - If the user may have deleted the wrong item, suggest recreating it or reviewing remaining items.
      x-ai-suggestions:
      - Use GET /checklists/{checklistId}/items to verify remaining items after deletion.
      - If bulk cleanup is needed, consider deleting the entire checklist instead.
