timers_reset

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

No annotations are provided, so the description must disclose behavioral traits. It only states the action without mentioning side effects, prerequisites (e.g., timer must exist), or whether the timer must be running. This is insufficient for an agent to understand the full impact.

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 brief (five words), which is concise but lacks structure. It is a single phrase rather than a sentence, and while it saves space, it could benefit from additional context like a complete sentence.

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) and the presence of many sibling timer tools, the description is incomplete. It does not explain the effect of resetting, how it differs from other timer operations, or any return value or status changes. An agent would need more information to use it correctly.

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% for the single parameter 'timerId'. The description does not add additional meaning beyond the schema, which is already clear. Baseline of 3 is appropriate since the schema handles parameter documentation adequately.

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 'Reset a specific timer' clearly identifies the action (reset) and the resource (specific timer). It distinguishes from sibling tools like timers_start, timers_stop, and timers_increment, which have different purposes. However, it does not define what 'reset' means in this context (e.g., to zero, to start time), which slightly reduces clarity.

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 usage guidelines are provided. The description does not indicate when to use this tool versus alternatives like timers_start or timers_operate_all. It also lacks prerequisites or context for resetting a timer.

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