ghl_brand_board_update_voice

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

Annotations indicate readOnlyHint=false, destructiveHint=false, etc. The description adds 'Update' but does not disclose whether updates are partial or full replacement, what side effects occur, or any specific behavioral traits beyond the annotations. Minimal extra value.

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 very short (two lines) and front-loaded with the action. No wasted words, but it could benefit from more structure (e.g., sentence about usage).

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?

No output schema defined, and description does not mention return value or error handling. Given the relatively simple operation, some context on what is returned (e.g., updated brand voice object) would improve completeness.

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% with descriptions for all parameters. The description adds no additional semantics beyond what the schema provides (e.g., for 'body' it just repeats the schema verbatim). Baseline 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 clearly states 'Update Brand Voice' and 'Update a brand voice by ID', which specifies the action and resource. It also provides the endpoint. It is distinct from sibling tools like create_voice and delete_voice, but could be more explicit about what exact fields are updated.

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 on when to use this tool vs alternatives (e.g., create_voice for new voices, delete_voice for removal). No prerequisites or context provided. The agent must infer usage from the tool name alone.

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