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

All annotations are false, so the description carries full behavioral disclosure. It thoroughly covers that the tool touches no credentials, changes nothing else, requires a human to complete the connection, has specific permission nuances, returns a specific shape, and repeats connect_url in a second content block. It also explains the post-call workflow. No contradiction with annotations exists.

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 one long paragraph but front-loads the core action and condition in the first sentence. It contains many necessary details (permissions, human step, output shape, follow-up). While somewhat verbose and could benefit from structure, every sentence contributes useful context, with no padding.

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 complexity, all-false annotations, and lack of an output schema, the description is remarkably complete. It covers when to use, prerequisites, side effects (none on credentials), return shape, and the required agent follow-up. An agent has everything needed to invoke the tool correctly and handle the result.

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 input schema already fully documents the only parameter `id` with 100% coverage, including its format (`conn_…`) and source (connection.list). The description adds no additional semantic meaning for the parameter beyond confirming it refers to an existing connection, so it meets the baseline but does not enhance understanding.

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 a specific action ('Mint a fresh connect_url') on a specific resource ('existing connection') under a specific status condition ('needs_reauth' or 'pending'). It clearly differentiates from sibling tools like connection create by focusing on reconnecting an existing connection, and even references connection.create's return shape to further define its role.

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 states when to use the tool (status 'needs_reauth' or 'pending') and gives detailed follow-up instructions (end reply, call connection.get later). It also clarifies permission requirements. However, it does not explicitly name alternative tools for conditions outside those statuses, leaving some inference to the agent.

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