vibo_capture_session

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

Beyond the readOnlyHint=false annotation, the description adds valuable behavioral context: it captures login, saves the token locally, and reuses it. It also explains the technical mechanism (fetchproxy bridge) and the user interaction needed (approve pair code).

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 is composed of three concise sentences that each add essential information: what it captures, the requirements, and the token reuse behavior. No unnecessary 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?

Although there is no output schema, the description fully explains the tool's purpose, prerequisites, and outcome (token saved and reused). It is complete for a one-time setup tool.

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?

With no parameters and 100% schema description coverage, the baseline is 4. The description is complete and does not need to add parameter 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?

The description clearly states the tool captures a Vibo login from a signed-in browser tab via the fetchproxy bridge. It specifies the use case for SSO accounts (Apple/Google/Facebook) and distinguishes from sibling tools which mostly handle events and songs.

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 provides explicit prerequisites (fetchproxy extension, signed into web.vibodj.com) and explains the first-use pair code approval. It implies the token is reused on future calls, indicating it's typically used once, though it doesn't explicitly state when not to use it.

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