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

Beyond the readOnlyHint=false annotation, the description reveals a crucial behavioral trait: the tool returns a preview unless confirm=true. This two-step confirmation mechanism is not captured by annotations and is essential for correct invocation.

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 consists of two concise sentences. The first clearly states the purpose, and the second highlights the key behavioral constraint. No superfluous words.

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?

Given the tool's simplicity and the absence of an output schema, the description covers the essential aspects: purpose and the confirm-gated mechanism. It doesn't elaborate on return values or prerequisites, but the schema and name fill most gaps.

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?

All four parameters are described in the schema (100% coverage), so the description adds little additional meaning. The mention of 'confirm-gated' ties to the confirm parameter but does not enhance the semantic understanding beyond what the schema already provides.

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 'Leave a comment on a timeline section' which clearly defines the action and target resource. The confirm-gated qualifier adds specificity that distinguishes it from similar tools like vibo_comment_on_song.

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?

The description explicitly indicates the tool is confirm-gated, and the schema details that confirm must be true to post, otherwise a preview is returned. This provides clear usage guidance, though it does not explicitly advise when to use this tool over siblings (but the name differentiates).

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