set_worksheet_caption

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

No annotations are provided, so description must carry behavioral information. It states the tool sets or clears a caption, implying a mutation. However, it does not disclose if the operation is reversible, if it requires permissions, or what the output schema indicates (return 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 a single, concise sentence that efficiently communicates the core functionality with no unnecessary 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?

Given the tool has 2 required parameters and no nested objects, the description is reasonably complete. However, it lacks details about return value (output schema exists but description doesn't mention it) and edge cases like clearing caption behavior.

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 description coverage is 0%, so the description must add meaning. It explains that the caption is 'plain-text' and that the tool can 'clear' (likely by empty string). This adds value beyond the schema, which only lists names and types. However, it does not detail what 'clear' means in terms of input.

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 or clears a plain-text worksheet caption, using the verb 'set' and specifying the resource (worksheet caption). It distinguishes from siblings like 'set_worksheet_hidden' by focusing on caption content.

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 versus alternatives. For instance, there is no mention that to clear a caption one can pass an empty string, nor when to use this over other worksheet modification tools.

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