Get Asset Upload URL

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

Beyond annotations (readOnlyHint=false, destructiveHint=false), the description adds workflow context: the tool returns upload_id and upload_url, and guides the user on how to use the URL and capture the ETag. It also mentions the 500MB limit. No contradictions with annotations.

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 front-loaded with the purpose and provides a clear workflow. It includes a useful curl example, but is slightly verbose. Overall well-structured and concise.

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?

The description is comprehensive: it explains the return values, how to use the URL, the follow-up tool (finalize_asset_upload), and a constraint (max file size). For a tool with 3 parameters and no output schema, it covers all essential context.

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%, so baseline is 3. The description adds context by explaining the role of contentType in the curl command and reinforcing the fileSize limit. This adds meaning beyond the schema's type descriptions.

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's purpose: to get a presigned URL for uploading a file to monday.com. It distinguishes from sibling tools like finalize_asset_upload by providing the initial step in a two-step workflow.

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?

The description provides explicit instructions on when to use this tool (to obtain an upload URL) and the subsequent steps (upload with curl, then call finalize_asset_upload). It mentions max file size but does not explicitly state when not to use it or mention alternatives.

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