vibo_capture_session

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

The description explains behavioral traits beyond annotations: it requires a browser extension, saves the token locally, and reuses it on future calls. Annotations only provide readOnlyHint=false, so the description adds valuable context about the capture and storage behavior.

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 concise (3 sentences), front-loaded with the action verb 'Capture', and includes essential prerequisites and behavior. Every sentence adds value without redundancy.

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?

The description lacks explicit details about the return value or outcome after capturing the session (e.g., success indication, token confirmation). While the token is said to be saved, the user may expect to know what the tool outputs. Given no output schema, the description should cover this. The tool is simple, so this is a moderate gap.

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 zero parameters, schema coverage is 100%. The description adds meaning by explaining that the tool captures the session from a signed-in browser tab, which is effectively the entire input context. A zero-parameter tool merits a baseline of 4, and the description fulfills that.

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's purpose: capturing a Vibo login session via fetchproxy for SSO accounts. It distinguishes itself from sibling tools (e.g., vibo_list_events) by focusing on session capture, which no other tool does.

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 clear usage context: it is for SSO login capture, requires the fetchproxy extension and being signed into web.vibodj.com, and explains the pairing process. However, it does not explicitly mention when not to use this tool or list alternatives, but given its unique role among siblings, this is a minor gap.

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