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

Annotations already declare readOnlyHint=true, idempotentHint=true, openWorldHint=false, destructiveHint=false, so the safety profile is fully covered and the bar is low. The description still adds real value beyond them by disclosing the shape of the response and the conditional behavior that the download link only exists "if rendered".

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; the most decision-relevant fact (it returns one clip) leads, and the returned fields follow compactly.

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?

With no output schema, the description usefully enumerates the returned fields and the conditional download link, which is exactly the burden it must carry. What is missing is any routing guidance relative to clipember_list_clips and clipember_get_clip_request, plus any hint about the clipId argument.

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 is the only place parameter meaning could be added, and it says nothing about clipId. The only hints (uuid type/pattern) come from the schema itself, which the description does not supplement with format, source, or lookup guidance.

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?

States a specific verb+resource ("Get a single clip's details") and enumerates the fields returned (score, hook, status, download link). The word "single" implicitly separates it from clipember_list_clips, but no sibling is named explicitly, so it stops short of a 5.

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 only implied: a reasonable agent infers this is for fetching one clip when a clipId is known, versus clipember_list_clips for enumeration. There is no explicit when-to-use, when-not-to-use, or named alternative, and no mention of where a clipId comes from.

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