Google Tasks Agent Skill

Google Tasks

_Independent, unofficial connector for Google Tasks. Not affiliated with, endorsed by, or sponsored by Google Tasks. "Google Tasks" is a trademark of its owner, used only to identify the service this connector works with._

Agent-callable tools for Google Tasks (the Google Tasks API v1). Manage task lists (list, get, create, rename, delete) and tasks (list, find by title, get, create, update, complete/reopen, reorder/reparent/move, delete, and clear completed). Authenticate once with a Zapier-managed Google connection (recommended) or a direct OAuth token. The connector exposes the full task surface as 13 single-purpose scripts with stable, predictable I/O — no triggers (it is non-polling).

When to use this

• Capture and organize to-dos — create tasks (optionally as subtasks or at a position), create and rename task lists.
• Review what's on a list — list active (or completed) tasks, find a task by title, get a task's details.
• Move work forward — mark tasks complete or reopen them, reorder or reparent tasks, move a task to another list.
• Prune — delete a task or list, or clear (hide) all completed tasks in a list.
• Use whenever the user wants to manage Google Tasks or their to-do list, even if they don't name Google Tasks explicitly.

Setup

This is an agentskills.io skill.

If the connector has not been installed as a skill yet, install it first with npx skills add zapier/connectors --skill google-tasks (or your harness's own skill-install mechanism), then continue here. Installing the skill copies these files, not dependencies. Before running the CLI, a local MCP server, or zapier-sdk auth commands, run npm install --omit=dev here once. Importing the published package as a dependency in your own project instead? That npm install already resolves everything — see references/use-as-sdk.md.

The connector runs on Node.js 22.18+. Pick the reference that matches how you're running it, and load it before doing anything else:

| You have... | Load |

| ----------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------ |

| An MCP-aware client — tools may already be loaded (e.g. mcp__google-tasks__<tool>), or you can register a local server yourself (or guide the user to) | references/use-as-mcp.md |

| Terminal / subprocess access (you can run node) | references/use-as-cli.md |

| Only your own code, importing this package as a dependency | references/use-as-sdk.md |

| No tool access, no terminal, no ability to import this package — you write your own code that calls the Google Tasks API directly (e.g. a code-execution sandbox) | references/use-as-recipe.md |

Scripts

All scripts use a single google-tasks connection.

| Script | Script name | Connections | Description |

| -------------------------------- | --------------------- | -------------- | ----------------------------------------------------------------------------------------- |

| scripts/listTaskLists.ts | listTaskLists | google-tasks | List the user's task lists (id + title). The resolver for any tasklist input. |

| scripts/getTaskList.ts | getTaskList | google-tasks | Get a single task list by id. |

| scripts/createTaskList.ts | createTaskList | google-tasks | Create a new task list. |

| scripts/updateTaskList.ts | updateTaskList | google-tasks | Rename a task list (title is the only editable field). |

| scripts/deleteTaskList.ts | deleteTaskList | google-tasks | Delete a task list and all tasks in it (irreversible). |

| scripts/listTasks.ts | listTasks | google-tasks | List/search tasks in a list; active-only by default, with completion/due/updated filters. |

| scripts/findTask.ts | findTask | google-tasks | Find a task in a list by title (exact match preferred). Resolves a title to a task id. |

| scripts/getTask.ts | getTask | google-tasks | Get a single task by id. |

| scripts/createTask.ts | createTask | google-tasks | Create a task (optionally a subtask / at a position). |

| scripts/updateTask.ts | updateTask | google-tasks | Update a task; set status to complete or reopen it. |

| scripts/moveTask.ts | moveTask | google-tasks | Reposition, reparent, or move a task to another list. |

| scripts/deleteTask.ts | deleteTask | google-tasks | Permanently delete a task. |

| scripts/clearCompletedTasks.ts | clearCompletedTasks | google-tasks | Hide all completed tasks in a list (recoverable; non-destructive). |

Auth

Every shape passes auth as one connection selector, not the secret — a [<resolver>:]<value> string. Every connector accepts zapier:<connection-id> (Zapier-managed auth — routes through Zapier's auth, retries, and governance layer); some also accept one or more direct-token resolvers (naming and count vary per connector) — check this connector's own resolvers rather than assuming. The <resolver>: prefix is optional; a bare value goes to the first resolver that claims it — a UUID-shaped bare value always claims zapier:. Each script declares the connections it needs and the resolvers each accepts. The exact syntax for passing a connection (and how to see this connector's resolver list) differs by shape — see the reference you loaded above.

Checking what's already configured first? Don't dump environment values to do it — env or env | grep <name> prints the value along with the name, leaking a live credential into the transcript if one is set. Check names only (env | cut -d= -f1 | grep -i <name>) or test a known name directly ([ -n "$VAR_NAME" ]).

No connection yet? Pick one — and follow the reference's own flow to obtain it; never just ask the user for a connection id or token as if they already have one memorized:

| | Load |

| ------------------------------------ | ---------------------------------------------------------------------- |

| Pass the credential directly | references/use-without-zapier.md |

| Route it through a Zapier connection | references/use-with-zapier.md |

Output format

Every script returns a { data, meta } envelope:

• data — the script's result (the shape its outputSchema declares; see the reference you loaded above for how to inspect a script's exact schema in your shape).
• meta.outputDataValidation — what validating data did:
• { skipped: false, droppedPaths: null } — validated, nothing removed.
• { skipped: false, droppedPaths: [...], instruction } — validated, but those paths were stripped from data: fields the script returned from the API that the outputSchema doesn't declare. If you need them, re-run with output validation skipped.
• { skipped: true } — validation was bypassed; data is the raw, unchecked script output.

Reading dropped fields / skipOutputDataValidation. To receive the raw, unvalidated result, opt out of output validation (the exact syntax differs by shape — see the reference you loaded above). Input validation is never skipped.

Trimming the result / filterOutputData. To shrink a large result down to the fields you need, pass a jq expression that post-processes data (again, exact syntax per shape). The jq runs against data only, NOT the { data, meta } envelope, so write it rooted at data (run the script's --help — or your shape's equivalent — to see its output schema). The transformed value replaces data, meta is preserved, and the result is NOT re-validated against the output schema.

Disambiguation & refusals

• Resolving a task or list by name. Before updating, completing, moving, or deleting a task referenced by title, resolve it first — findTask returns the best title match, or listTasks to see candidates. If two or more tasks in the list have the same title (exact, case-insensitive), don't silently pick one: list the tied candidates with a distinguishing field (due date, status, notes) and ask which one. If exactly one matches, act on it — don't over-ask. Same rule for listTaskLists when a list is named.
• Unsupported operations — say so, don't fake it. This connector cannot: create or edit recurring tasks (the API has no recurrence fields — recurrence is managed only in the Google Tasks app), set a task's time of day or reminder (due is date-only — the time is discarded), or reorder by writing position (use moveTask). If asked for one of these, say it's unsupported and stop — do not substitute another tool and report success for something you didn't do.
