# TickTick

Operate **TickTick** through your OOMOL-connected account. This skill calls the `ticktick` connector with the [oo CLI](https://github.com/oomol-lab/oo-cli); OOMOL injects credentials server-side, so you never handle raw tokens.

Category: Productivity. Exposes 20 action(s).

## Running an action

Assume the user has already installed the oo CLI, signed in, and connected TickTick. **Do not run `oo auth login` or open the connection URL proactively — just run the action.** Fall back to [First-time setup](#first-time-setup) only when a command actually fails with an auth or connection error.

**1. Inspect the contract** to get the authoritative input/output schema before building a payload:

```bash
oo connector schema "ticktick" --action "<action_name>"
```

**2. Run the action** with a JSON payload that matches the input schema:

```bash
oo connector run "ticktick" --action "<action_name>" --data '<json>' --json
```

- `--data` takes a JSON object string or `@path/to/file.json`; omit it to send `{}`.
- The response is `{ "data": ..., "meta": { "executionId": "..." } }`; the execution id lives under `meta.executionId`.

Each action below links to a reference file with its purpose and exact commands. Read the linked file, then fetch the live schema with `oo connector schema` before constructing `--data`.

## Available actions

- [`complete_task`](actions/complete_task.md) — Mark a TickTick task as completed by project ID and task ID.
- [`create_or_update_habit_checkin`](actions/create_or_update_habit_checkin.md) — Create or update a TickTick habit check-in for a date stamp.
- [`create_project`](actions/create_project.md) — Create a TickTick project with optional color, sort order, view mode, and kind.
- [`create_task`](actions/create_task.md) — Create a TickTick task under a project with optional schedule, reminders, recurrence, and checklist items.
- [`create_task2`](actions/create_task2.md) — Create a TickTick task under a project. This deprecated compatibility alias maps to the same official create-task API as create_task.
- [`delete_project`](actions/delete_project.md) — Delete a TickTick project by project ID. The connector treats a missing project as already deleted.
- [`delete_task`](actions/delete_task.md) — Delete a TickTick task by project ID and task ID. The connector treats a missing task as already deleted.
- [`filter_tasks`](actions/filter_tasks.md) — Filter TickTick tasks by project, date range, priority, tags, and status by using the official filter endpoint.
- [`get_habit`](actions/get_habit.md) — Get a TickTick habit by its habit ID.
- [`get_project_by_id`](actions/get_project_by_id.md) — Get a TickTick project by its project ID.
- [`get_project_with_data`](actions/get_project_with_data.md) — Get a TickTick project together with its undone tasks and columns by project ID.
- [`get_task_by_project_and_id`](actions/get_task_by_project_and_id.md) — Get a TickTick task by project ID and task ID.
- [`get_user_project`](actions/get_user_project.md) — List the projects available to the connected TickTick account.
- [`list_all_tasks`](actions/list_all_tasks.md) — List undone TickTick tasks across projects. This is a connector-level aggregate helper over list-projects plus project-data fetches.
- [`list_completed_tasks`](actions/list_completed_tasks.md) — List completed TickTick tasks within optional project and date filters by using the official completed-tasks endpoint.
- [`list_habit_checkins`](actions/list_habit_checkins.md) — List TickTick habit check-ins for one or more habits over a date stamp range.
- [`list_habits`](actions/list_habits.md) — List habits available to the connected TickTick account.
- [`move_tasks`](actions/move_tasks.md) — Move one or more TickTick tasks between projects by using the official move endpoint.
- [`update_project`](actions/update_project.md) — Update a TickTick project by project ID.
- [`update_task`](actions/update_task.md) — Update a TickTick task by task ID and project ID, including checklist items and recurrence fields.

## Safety

- Read actions (get / list / search) are safe to run directly.
- **Create, update, send, or post actions change TickTick state — confirm the exact payload and effect with the user before running.**
- **Delete or remove actions are destructive — always confirm the target and get explicit approval first.**

## First-time setup

These are **one-time** steps — do not repeat them on every call. Run a step only when a command fails for the matching reason.

- **`oo: command not found`** — install the oo CLI (other platforms: <https://cli.oomol.com/install-guide.md>):

  ```bash
  curl -fsSL https://cli.oomol.com/install.sh | bash    # macOS / Linux
  ```

  ```powershell
  irm https://cli.oomol.com/install.ps1 | iex           # Windows PowerShell
  ```

- **Not signed in / authentication error** — sign in to your OOMOL account once:

  ```bash
  oo auth login
  ```

- **`scope_missing` / `credential_expired` / `app_not_ready` / `app_not_found`** — TickTick is not connected, or the connection expired or lacks a scope. Connect once (auth type: OAuth2, API key) at:

  ```text
  https://console.oomol.com/app-connections?provider=ticktick
  ```

- **HTTP 402 / `OOMOL_INSUFFICIENT_CREDIT`** — billing stop. Recharge at `https://console.oomol.com/billing/token-recharge` before retrying.
