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

The description adds meaningful behavior beyond the readOnly/destructive annotations: results are newest first, include render status, and expose download and stream links that expire after 24 hours. It does not cover pagination or rate limiting, but with annotations carrying the safety profile this is solid additional context.

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 well-formed sentence with zero waste, and the core resource plus important return attributes are front-loaded.

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 simple two-parameter list tool with annotations and no output schema, the description gives a good sense of what is returned. However, because parameter descriptions are absent from the schema and the description does not explain `limit` or `status`, the definition is not fully complete for correct invocation.

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 compensate for the undocumented parameters. It mentions render status conceptually but does not explain the `status` filter values or what `limit` controls, leaving both parameters largely unclarified.

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 a specific verb and resource: listing recent clips from the account's catalog. It adds useful scope and return details (newest first, render status, download/stream links), but does not explicitly differentiate itself from siblings such as generate_clips or list_creations.

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?

Usage is implied by 'Recent clips of the account's catalog,' which tells an agent this is for listing clips. However, there is no explicit when-to-use guidance, exclusions, or direction to alternatives like generate_clips or list_creations.

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