set_metronome

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

No annotations are provided, so the description alone must carry the behavioral disclosure. It only states the basic action without mentioning side effects, reversibility, permissions, or how to verify the state change, which would be valuable for a mutation tool.

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, with the purpose front-loaded in the first sentence and the parameter explanation in a single line. Every word earns its place, with no waste.

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 one-parameter setter with no output schema, the description covers the essential purpose and parameter semantics. It could reference get_metronome_state for a more complete picture, but the tool's simplicity makes the existing description sufficient.

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 description explicitly explains 'enabled: True to enable, False to disable', adding clear meaning beyond the input schema's bare title 'Enabled'. This fully compensates for the lack of schema descriptions.

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 'Turn the metronome on or off' clearly states the action (turn on/off) and resource (metronome). This distinguishes it from the sibling tool get_metronome_state, which is the read counterpart.

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?

Usage is implied from the verb 'turn' and the 'enabled' parameter, but the description does not explicitly mention when to use this tool versus get_metronome_state or any other alternatives. There is no explicit exclusion or contextual guidance.

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