set_metronome

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

With no annotations provided, the description carries the full burden. It states the action (turning the metronome on/off) and explains the 'enabled' parameter, but it does not disclose any side effects, prerequisites, or persistence semantics. For a simple boolean setter, this is adequate but minimal.

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 and front-loaded. It states the core action in one sentence and immediately follows with a parameter explanation. Every sentence serves a purpose without redundant elaboration.

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?

This is a low-complexity tool with a single required boolean parameter and no output schema. The description fully covers what the tool does and what the parameter means. It is complete for the tool's simplicity and context.

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 0%, so the description compensates by explaining the sole parameter: 'enabled: True to enable, False to disable.' This adds semantic meaning beyond the raw boolean type, clearly mapping each value to its effect on the metronome.

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 action: 'Turn the metronome on or off.' It uses a specific verb and resource, distinguishing it from the sibling get_metronome_state, which extracts state rather than changing it.

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?

The description implies usage by stating the on/off behavior, but it does not explicitly mention when to use it versus alternatives like get_metronome_state or toggle_device. There is no clear when-to-use or when-not-to-use guidance beyond the direct purpose.

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