complete_google_task

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries full responsibility for behavioral disclosure. It implies a mutation (status change) but does not mention idempotency, error behavior, auth requirements, or what happens if the task is already completed. The output schema is present but not described, so the agent lacks context on return values.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, front-loaded sentence that directly states the tool's purpose. Every word earns its place, with no fluff or repetition. It is appropriately concise for a simple operation.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's low complexity (one parameter) and the presence of an output schema (which can convey return structure), the description is reasonably complete. It covers what the tool does and how to invoke it. The main gaps are behavioral nuances (e.g., failure cases) but these are less critical for a straightforward completion action.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema's parameter is a bare string 'task_id' with no description. The description clarifies that this is the ID of the Google Task being completed, which adds meaning. However, it does not provide format, source, or validation details, and there is only one parameter, so the added value is modest.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action ('Marks a Google Task as completed') and the resource/method ('using its Task ID'). It distinguishes from sibling tools like add_google_task or delete_google_task because it specifically addresses completing an existing task.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description gives no guidance on when to use this tool versus alternatives, nor any prerequisites or exclusions. It simply states the action, leaving the agent to infer when completion is appropriate. No mention of when not to use it or related tools like list_google_tasks.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
