timers_reset

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

No annotations are provided, so the description carries full burden. 'Reset a specific timer' implies a mutation operation but doesn't disclose what reset actually does behaviorally - whether it affects timer state, requires specific permissions, has side effects, or what the expected outcome is. For a mutation tool with zero annotation coverage, this is inadequate.

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 just four words - 'Reset a specific timer'. It's front-loaded with the core action and target, with zero wasted words. Every word earns its place in conveying the essential 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?

For a mutation tool with no annotations and no output schema, the description is insufficiently complete. It doesn't explain what 'reset' means operationally, what happens to the timer, whether there are side effects, or what the agent should expect as a result. Given the complexity of timer operations and the lack of structured documentation, more context is needed.

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% with the single parameter 'timerId' well-documented as 'The ID of the timer to reset'. The description doesn't add any additional parameter semantics beyond what the schema provides, which is acceptable given the high schema coverage. The baseline of 3 is appropriate when the schema does the parameter documentation work.

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 states the action (reset) and target (timer), but it's vague about what 'reset' means in this context - does it restart from zero, pause, or clear? It distinguishes from siblings like 'timers_start', 'timers_stop', and 'timers_increment' by focusing on resetting, but doesn't specify how it differs from those operations.

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 about when to use this tool versus alternatives. With sibling tools like 'timers_start', 'timers_stop', 'timers_increment', and 'timers_operation', the description doesn't indicate whether reset is for zeroing a running timer, restarting a stopped one, or something else. No prerequisites or context for usage is mentioned.

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