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

Annotations already declare this is a non-destructive, idempotent write (readOnlyHint=false, idempotentHint=true, destructiveHint=false), and the description's 'clear (0)' is consistent with resubmission semantics. Beyond that the description adds little: it does not say whether ratings are per-user, whether prior feedback is overwritten, or what the call returns.

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 that enumerates the value domain with zero filler. Nothing could be removed without losing information.

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 two-parameter tool with full annotation coverage and no output schema, the description plus annotations give an agent enough to call it correctly. The only remaining gap is the absence of any statement about permission requirements or post-call effect.

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 carry parameter meaning; it does so for the non-obvious parameter by naming what -1, 0, and 1 mean ('thumbs down', 'clear', 'thumbs up'), which the bare consts do not convey. clipId is left unexplained, but its name and uuid format make it self-evident.

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 specific verb (submit/rate) and resource (clip), and enumerates the meaning of each rating value. No sibling tool performs feedback submission, so the function is unambiguous, though it never explicitly positions itself against neighbors like clipember_get_clip or clipember_share_clip.

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?

There is no guidance on when to use this versus alternatives, no prerequisites (e.g., must the clip belong to the caller?), and no statement about whether a rating can be changed or removed. Usage is only implied by the verb 'feedback'.

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