set_fermentation_chamber_light_enabled

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

With no annotations, the description must disclose behavioral traits, but it only mentions the action and states. It does not explain the meaning of 'Auto', whether the operation is reversible, if any prerequisites (e.g., chamber existence) apply, or what side effects may occur. This is minimal disclosure.

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 a single, front-loaded sentence with no wasted words. It clearly conveys the tool's purpose and the key parameter values, making it concise and well-structured.

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 simplicity of the tool (2 params, no output schema, no annotations), the description is adequate but not fully complete. It does not state when to use it (e.g., during active fermentation), what 'Auto' implies, or any error conditions. Since the tool is a simple setter, this level is acceptable but leaves some gaps.

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 coverage is 100%, so the schema already documents both parameters well. The description adds no extra meaning beyond what the schema provides (e.g., states are already defined in the enum). It does not clarify any nuances about chamber_id or state beyond the schema, so the baseline score of 3 is appropriate.

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 states the action ('Control') and the target resource ('light of a fermentation chamber'), with the allowed states (On, Off, Auto). It clearly distinguishes from sibling tools like set_fermentation_chamber_temperature by focusing on light control. However, 'Control' is slightly less specific than verbs like 'Set' or 'Turn', so it loses a point.

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 this tool versus alternatives such as set_fermentation_chamber_heating_enabled or set_fermentation_chamber_pid_enabled. The description simply states its function without contextual cues or exclusions, leaving the agent to infer usage from sibling names.

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