twprojects-complete_timer

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

Annotations are minimal (only title), so the description must carry the burden. It discloses that the tool stops and converts, implying mutation, but fails to mention side effects (e.g., timer cannot be resumed after completion), authorization needs, or what happens to the original timer.

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 concise sentence with no wasted words. It efficiently communicates the core action.

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 low complexity (1 param, no output schema), the description covers the basic purpose. However, it lacks details on return behavior (e.g., success indication or created timelog ID) and potential failure conditions. It is minimally adequate but not thoroughly complete.

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 coverage is 100% with the 'id' parameter well-described as 'The ID of the timer to complete.' The description adds no extra meaning beyond the schema, so a baseline score of 3 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 action: stopping a timer and converting it to a timelog. The verb 'Stop' and 'convert' combined with the resource 'timer' and 'timelog' make the purpose distinct from sibling tools like 'pause_timer' or 'resume_timer', though the conversion aspect is not further elaborated.

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 (e.g., pausing vs. completing). There is no mention of prerequisites (e.g., timer must be running) or scenarios where it should not be used.

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