Build a Cloudinary delivery URL

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

Annotations already declare readOnlyHint=true and openWorldHint=true, and the description is consistent with a non-mutating URL builder. It adds little beyond that — no note on whether the public_id is validated, what happens if it doesn't exist, or how defaults for resourceType/version resolve.

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?

A single front-loaded sentence with zero filler that states the action, the input, and the optional modifier. Nothing to trim.

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?

For a read-only tool with no output schema, the description conveys that the output is a delivery URL, which is the essential return contract. It is still thin on parameter defaults (resourceType, version) and on the asset-existence prerequisite.

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 only 25% (just the transformation string), so the description must compensate. It names public_id and transformation but says nothing about version or resourceType, leaving half the parameters undocumented in both description and schema.

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?

Specific verb ('Construct') plus resource ('public delivery URL') tied to an existing public_id. It clearly separates itself from cloudinary_upload and cloudinary_delete, though it doesn't explicitly contrast with cloudinary_variants, which could also produce URLs.

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 phrase 'for an existing public_id' implies the prerequisite that the asset must already exist, giving implicit usage guidance. However, it names no alternative tool and gives no explicit when-to-use vs when-not-to-use condition.

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