Attach URL to Row

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

Discloses that it creates a hyperlink attachment and returns a new attachment ID and metadata. No annotation contradictions. Lacks details on error conditions or rate limits.

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?

Concise with only necessary information. Structured with purpose, Args, and Returns. No extraneous text.

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?

Covers purpose, parameters, and return value. For a simple tool with no output schema and 5 params, this is sufficient. Lacks example usage or prerequisites.

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 Args section adds meaning beyond the schema, explaining each parameter's role (e.g., 'Target sheet ID'). Schema covers 40% but description compensates by listing all.

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?

Clearly states 'Attach a URL link to a specific row' and distinguishes from siblings like smartsheet_list_attachments. The verb 'attach' and resource 'URL to row' are specific.

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?

Describes the action but does not provide explicit guidance on when to use this tool versus alternatives like uploading files or adding comments. Only implied by context.

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