task_complete

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

Annotations provide idempotentHint=true, and the description adds the behavioral detail that the latest checkpoint is retained. However, it does not disclose any destructive actions (if any) or permission requirements. Beyond the annotation, the description adds modest value.

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 that conveys the core action and a key behavioral trait. No extraneous information, perfectly front-loaded.

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 simplicity (mark a task complete) and the presence of an output schema, the description is largely complete. However, the lack of parameter semantics and usage guidance is a minor shortfall for a tool with a sibling set that includes task lifecycle operations.

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 input schema has 2 required string parameters (taskId, projectId) with 0% description coverage in the schema. The tool description does not add any meaning to these parameters—no format hints, no examples, no explanation of how to obtain them. This is a significant gap for a tool with no param descriptions in the schema.

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 ('mark persistent task completed') and the key behavioral nuance ('retaining its latest checkpoint'). It distinctively separates from sibling tools like task_checkpoint (which likely only saves state) and task_start (which begins a 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 purpose implies usage for completing a task, but no explicit guidance is given on when to use versus alternatives like task_checkpoint or task_start. There are no exclusions or context about prerequisites (e.g., task must be started).

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