vibo_comment_on_song

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

Description adds value beyond annotations by revealing the confirm-gated workflow. Annotations only indicate write operation (readOnlyHint=false), but the two-step preview-then-confirm behavior is not captured there.

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?

Extremely concise single sentence with no wasted words. Every part adds value: what, where, and a key behavioral note.

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 tool with 5 parameters and no output schema, the description covers the core functionality and a key behavioral aspect. However, it lacks details about what the tool returns (e.g., confirmation message) and assumes knowledge of the confirmation pattern.

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 has 100% coverage with descriptions for all parameters. Description adds minimal extra meaning beyond listing the tool purpose. The 'Confirm-gated' hint relates to the confirm parameter but adds little new semantic information.

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?

Description clearly states the action ('Leave a comment / note') and the resource ('on a specific song'). It distinguishes from sibling tools like 'vibo_comment_on_section' and 'vibo_delete_song_comment'.

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?

Mentions 'Confirm-gated' but does not explicitly state when to use this tool versus alternatives like commenting on a section. Could provide more guidance on the two-step confirmation process.

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