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

The annotations indicate a mutating but non-destructive, idempotent operation. The description adds a valuable behavioral guarantee that only passed fields are changed, which goes beyond the schema and annotations. It does not disclose side effects or authorization requirements, but the annotation profile already covers the main safety traits.

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?

Two short sentences with no filler. The action and affected fields are front-loaded, and the second sentence adds the most important behavioral nuance without repeating schema details.

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?

Adequate for a straightforward update operation with a safe annotation profile, but incomplete around parameter semantics: password is undocumented in both description and schema, and there is no output schema to clarify the response. An agent can call it correctly but may mis-handle password/privacy without extra information.

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 17%, so the description needed to compensate. It repeats property names but does not explain the password field, the meaning of the privacy and sort enums, or the relationship between password and privacy=password. This leaves a significant parameter-semantics gap.

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 states a concrete action ('Update') on a specific resource ('a showcase') and lists the affected fields: name, description, privacy, and sort order. This clearly distinguishes it from create/get/delete showcase tools and from update_video/update_folder, and the phrase 'Only the fields you pass change' reinforces that this modifies rather than replaces.

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?

It is clear this is for modifying an existing showcase rather than creating, getting, or deleting one. The partial-update sentence provides a practical calling guideline, though no explicit alternatives or when-not-to-use conditions are named.

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