twprojects-complete_timer

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

Discloses that the timer is stopped permanently and converted, implying irreversibility. Annotations indicate non-read-only and non-idempotent, so description adds context about the conversion. No contradictions.

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?

Two efficient sentences with no wasted words. Front-loaded with the primary action, then the alternative.

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?

For a simple tool with one parameter and no output schema, the description is complete: explains what it does, how it differs from pause, and implies irreversibility. No missing essential information.

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?

Only one parameter (id) with schema description 'The ID of the timer to complete.' Schema coverage is 100%, so description adds no extra meaning beyond schema. Baseline 3.

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?

Description clearly states the action: stop a timer permanently and convert to timelog. It specifies the resource (timer) and outcome (timelog), and distinguishes from the sibling pause_timer.

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?

Explicitly guides when to use this tool vs pause_timer: 'Use pause_timer to pause without converting.' Provides clear alternative.

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