todo_complete_task

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

No annotations are provided. The description mentions 'via Reminders sync', which hints at cross-platform synchronization, but does not disclose permissions, side effects, or whether the action is reversible. Minimal behavioral insight beyond the core function.

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 sentence of 12 words, very concise and front-loaded with the action. However, it omits crucial information about task identification, sacrificing completeness for brevity.

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?

With no output schema and empty input schema, the description must explain how the tool knows which task to complete. It does not. For a tool that operates on an implicit task (likely the currently active one), this is a critical gap. The 'via Reminders sync' offers minor context but is insufficient.

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?

There are no parameters, and schema coverage is 100%. The description does not add any parameter information, but none is needed. However, it fails to explain how the target task is determined, which is an implicit parameter. Still, baseline 4 is appropriate.

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 verb 'marks as complete' and the resource 'Microsoft To Do task'. It is distinct from siblings like complete_reminder and complete_omnifocus_task. However, it does not explain how the specific task is identified, which is ambiguous since the input schema has no parameters.

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?

No guidance on when to use this tool vs. alternatives like complete_reminder or complete_omnifocus_task. The description provides no context for when to choose this over siblings.

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