get_image_settings

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

Annotations already declare readOnlyHint, openWorldHint, idempotentHint, and destructiveHint. The description adds no extra behavioral context (e.g., no mention of side effects, precision, or response format). With annotations covering the safety profile, a score of 3 is appropriate as it does not contradict but also does not enhance.

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 concise sentence that immediately conveys the action and resource. It is front-loaded with the key information and contains no extraneous words.

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?

With no output schema, the description lacks information about the return format or structure of the settings. It lists examples but does not fully describe what the agent can expect. This is adequate but incomplete for a tool that retrieves data.

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 input schema has 100% description coverage, with a clear description for the single parameter 'channel'. The tool description does not add any additional meaning or usage details beyond the schema, so baseline 3 applies.

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?

Description clearly states the verb 'Get' and identifies the resource as 'current image sensor settings', listing examples like brightness, contrast, white balance. This distinguishes it from sibling tools such as 'set_image_settings' (write) and 'get_capture_mode' (different resource).

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 vs alternatives like 'get_capture_mode' or 'get_snapshot'. The description only states what it does, not the context or conditions for use.

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