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

Annotations already declare readOnlyHint=true, destructiveHint=false, idempotentHint=true, and the description is fully consistent, adding useful context beyond them: it produces step-by-step instructions (screens, buttons, fields) and 'opens nothing by itself,' so no side effects occur. It also points to the tools that actually perform the mutation. Auth requirements and latency are not addressed, so it falls short of a 5.

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 core behavior is front-loaded in the first two sentences, but 'from ChatGPT, Claude or any AI agent' is filler and the closing sentence about Vimeo's REST API, OAuth 2.0, and the remote MCP beta does not change how an agent invokes this tool. Roughly a third of the text does not earn its place.

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 parameters, no output schema, and safety fully covered by annotations, the description supplies what is missing: what the tool returns and what to do next via cotlet_browser_*. The main remaining gap is that it does not specify whether the guide requires any input context (e.g., which videos or target folder) or how it selects them.

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?

The tool takes zero parameters, so per the baseline the schema carries the full burden and the description need not add parameter meaning. Nothing is undocumented or ambiguous.

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 names a specific verb and resource and immediately resolves the name/behavior tension by saying it 'Returns how to do it in Vimeo step by step ... and opens nothing by itself.' An agent can tell this is an instruction-returning guide rather than an executor. It does not explicitly differentiate from siblings like vimeo_add_videos_to_showcase, which keeps it below 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?

It gives an implied workflow: call this first, then perform the action 'with the cotlet_browser_* tools in the user's Vimeo Cloud Browser,' and scopes it to 'the user's own Vimeo account.' However, it never states when NOT to use it or names an alternative sibling, so the routing guidance is inferred rather than explicit.

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