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

Discloses level mapping and raw return value, and explains the proprietary protocol. However, missing side effects, persistence, error behavior, and prerequisites (e.g., camera must be connected).

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?

Two concise sentences, front-loaded with the main action and mapping. No fluff.

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?

Explains level and return, but misses explanation of camera parameter, error handling, and relationship to auto mode. Adequate but not comprehensive.

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 'level' parameter is well explained (0-100 mapping). The 'camera' parameter is not described at all, leaving ambiguity about its value and purpose.

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 sets exposure manually with a normalized level (0-100) mapped to the device's range, and distinguishes it from automatic exposure and other image adjustments.

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 explicit guidance on when to use this tool versus alternatives like auto exposure or general image adjust. The protocol note is technical but doesn't clarify usage context or prerequisites.

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