complete_task

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

With no annotations and only a one-sentence description, the behavioral traits are severely under-disclosed. The description implies a state mutation but does not address permission requirements, side effects, idempotency, or error conditions. The full burden falls on the description, which fails to provide sufficient transparency.

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 extremely concise with a single sentence. While it avoids verbosity, it sacrifices critical information. It is minimally viable but lacks structure and depth.

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 absence of annotations, output schema, and extensive sibling tools, the description is incomplete. It does not explain return values, effects on related entities, or when other tools (e.g., 'update_todo', 'uncomplete_task') might be more appropriate. For a simple tool, basic usage context is missing.

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?

Schema description coverage is 0%, and the description adds no meaning beyond the schema. The single parameter 'task_id' is not elaborated on—no explanation of how to obtain its value or any constraints. The description fails to compensate for the lack of schema annotations.

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 'Mark a task as complete' provides a clear verb ('mark') and resource ('task') with a specific state change ('complete'). It effectively differentiates from the sibling tool 'uncomplete_task' which performs the opposite action.

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 is provided on when to use this tool versus alternatives. There is no mention of prerequisites, when not to use it, or comparison with other tools like 'uncomplete_task'. The description offers no contextual usage advice.

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