toggle_lights

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

The description discloses the core behavior of toggling lights, but without annotations, it does not mention side effects, state outcomes, or any constraints. It 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, using only two lines to convey purpose and parameter details. It is front-loaded and contains no redundant information.

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 toggle tool with an output schema, the description is minimally complete. However, it omits edge cases, permission requirements, or return behavior, leaving room for improvement.

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?

With 0% schema description coverage, the description effectively explains the 'light_names' parameter as an optional list. This adds crucial meaning beyond the schema's raw type definition.

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 verb 'toggle' and resource 'lights', with an explicit note about all or specified lights. It distinguishes itself from siblings like turn_on, turn_off, and flash_lights by focusing on toggling state.

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 on when to use toggle_lights versus turn_on/turn_off or other alternatives like flash_lights. The description lacks context for appropriate usage scenarios.

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