## Tools available

**14** tools available. First 12:

- `TICKTICK_COMPLETE_TASK` — Complete Task — Marks a TickTick task as complete. Requires both the project_id and task_id, which can be obtained from TICKTICK_LIST_ALL_TASKS or TICKTICK_CREATE_TASK actions. This action is idempotent - completing an already-completed task will succeed without error. Completed tasks are removed from default/active views and appear only in completed task filters.
- `TICKTICK_CREATE_PROJECT` — Create Project — Create a new project (list) in TickTick. Projects organize tasks and notes. Use this to set up a new project with optional customizations like color, view mode, and type. The created project's ID can be used with other actions like TICKTICK_CREATE_TASK.
- `TICKTICK_CREATE_TASK` — Create Task — Tool to create a new task in TickTick. Use after you have task details such as title, dates, and optional reminders or subtasks.
- `TICKTICK_CREATE_TASK2` — Create Task (Deprecated) — DEPRECATED: Use TICKTICK_CREATE_TASK instead. Tool to create a new task in a specified project. Use when you need to create a task with required title and projectId, plus optional dates, priority, reminders, and subtasks.
- `TICKTICK_DELETE_PROJECT` — Delete TickTick Project — Permanently deletes a TickTick project by its ID. All tasks within the project will also be deleted. Note: This operation is idempotent - deleting a non-existent project ID returns success. Use TICKTICK_GET_USER_PROJECT to list available projects and their IDs before deletion.
- `TICKTICK_DELETE_TASK` — Delete Task — Tool to permanently delete a specific task — irreversible, no recovery. Use when you need to remove a task from a project after confirming both project and task IDs. Returns an empty data object on success; check status/success flags rather than response payload. When moving tasks between projects via create+delete, comments and history are lost.
- `TICKTICK_GET_PROJECT_BY_ID` — Get Project By ID — Tool to retrieve a specific TickTick project by its unique ID. Use when you need detailed information about a particular project after obtaining its project ID.
- `TICKTICK_GET_PROJECT_WITH_DATA` — Get project with data — Retrieve a project's associated data (incomplete tasks, columns). IMPORTANT: This endpoint only returns INCOMPLETE tasks. Completed tasks are automatically filtered out by the TickTick API. An empty tasks list means either the project has no tasks at all, or all tasks have been completed. For completed tasks, check the TickTick app or web interface directly. Columns are only present for kanban-style projects; list-view projects return an empty columns array. Join tasks to columns via each task's columnId field. For large projects, results may paginate at ~100 items per page — iterate all pages and deduplicate by taskId. Multiple tasks can share the same title; always use taskId for follow-up create, update, or delete calls. All filtering by name, tag, or other fields must be done client-side. Scope is project-only — Inbox and other projects are excluded.
- `TICKTICK_GET_TASK_BY_PROJECT_AND_ID` — Get Task By Project And ID — Tool to retrieve a specific TickTick task by project ID and task ID. Use when you need detailed information about a particular task within a project.
- `TICKTICK_GET_USER_PROJECT` — Get User Projects — Retrieves all projects accessible to the authenticated user, including personal and shared projects. Use this tool to list available projects before creating tasks or to get project IDs for other operations. Returns project metadata including name, color, view mode, and organization details. Always use returned projectId values (not project names) when calling TICKTICK_CREATE_TASK, TICKTICK_UPDATE_TASK, or TICKTICK_GET_PROJECT_WITH_DATA. The inbox project may not appear in results — omit projectId in TICKTICK_CREATE_TASK to target the inbox. Non-kanban projects return an empty columns array; check viewMode before assuming columns exist.
- `TICKTICK_LIST_ALL_TASKS` — List All Tasks — Tool to list all open/undone tasks across all user projects in one call. This is a composite operation that internally fetches all projects and aggregates their tasks. Use when you need a comprehensive view of pending work across the entire account. Note: Only returns open/undone tasks; completed task history is not available in TickTick OpenAPI v1.
- `TICKTICK_OAUTH2_AUTHORIZATION_STEP1` — Generate OAuth2 Authorization URL — Tool to generate the TickTick OAuth2 authorization URL. Use to redirect the user to obtain the authorization code (step 1). Re-run this tool if downstream TickTick calls return HTTP 401 (expired/invalid token) to obtain a fresh authorization code.

## Auth

Auth schemes: `OAUTH2`. Managed by Definable: `OAUTH2` — no client credentials required from the user.

## How agents use Ticktick

Inside a Definable workflow, Ticktick is one of the tools the **Distributor specialist** can call. Example coordination patterns:

- **Researcher → Ticktick** — the Researcher (GPT-5.5) pulls context from Ticktick (records, threads, documents), synthesises findings, and briefs the rest of the team.
- **Writer → Distributor → Ticktick** — the Writer (Claude Opus 4.7) drafts copy in brand voice, the Verifier passes it, then the Distributor writes the result into Ticktick (create record, post message, draft email).
- **Designer / Engineer → Distributor → Ticktick** — the Designer ships an asset or the Engineer ships a code change, the Distributor delivers it via Ticktick (attach file, open PR comment, post status).

The Verifier checks every Ticktick call. On rate limit, schema drift, or auth refresh it self-heals and retries — the workflow completes without manual intervention.
