twprojects-complete_timer

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

The description discloses key behavioral traits beyond annotations: the action is 'permanent' and results in a conversion to a timelog. This adds meaningful context to the annotation flags. However, it does not mention permissions or further side effects, but for a simple single-id tool, this is sufficient.

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 two sentences, directly front-loaded with the action, and contains no redundant or irrelevant content. Every word serves a purpose.

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 (one parameter, no output schema), the description is complete enough: it states the permanent action, the conversion result, and the alternative for pausing. It could be slightly richer by explaining what happens to the resulting timelog, but not necessary for a well-scoped timer tool.

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 already fully documents the only parameter ('id' with description 'The ID of the timer to complete'), so the description adds no additional parameter semantics. Schema coverage is 100%, warranting the baseline score.

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 tool's function: 'Stop a timer permanently and convert it to a timelog.' It uses specific verbs ('stop', 'convert') and resources ('timer', 'timelog'), and distinguishes itself from the sibling tool pause_timer with an explicit contrast.

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?

It explicitly provides usage guidance by saying 'Use pause_timer to pause without converting,' which tells the agent exactly when to choose this tool over a direct alternative. This is clear when-to-use/when-not-to-use information.

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