execute_task

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

No annotations exist. The description only says 'mark as completed with a result', lacking details on side effects, reversibility, prerequisites, or what happens on conflict (e.g., task already completed).

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 at 6 words, front-loading the core action. However, it could include slightly more context without significant bloat.

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 complexity (one required parameter, one optional object, many siblings, no output schema), the description is too brief. It doesn't explain the result object's purpose, possible side effects, or relationship to other tools like 'get_task'.

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 100%, so baseline is 3. The description adds no extra meaning beyond the schema; it re-emphasizes 'result' as part of the action but doesn't clarify the structure or semantics of the result object.

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 states the verb 'Mark' and resource 'task', and includes the key action 'completed with a result', which clearly indicates finalizing a task with output. However, it does not further differentiate from siblings like 'update_task' or 'fail_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?

No guidance on when to use this tool versus alternatives. With many sibling tools (e.g., 'fail_task', 'retry_task', 'update_task'), the agent lacks context for appropriate usage.

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