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

The description discloses a non-obvious behavior beyond the annotations: this tool does not directly connect the account, it only generates a one-time URL that the user must open and authorize. This meaningfully complements openWorldHint=true and readOnlyHint=false. It stops short of explaining the post-authorization state, but the key behavioral trait is present.

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?

Two short sentences with zero filler. The first sentence states the deliverable (one-time authorization URL) and the second states the required user action, making the tool's flow immediately understandable.

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 one-parameter tool with an output schema, the description captures the essential flow: generate a URL, user authorizes in a browser. It does not mention what happens after authorization or how to use the URL, but the simple scope and available schema make this adequate.

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 schema has one parameter, platform, with a fully enumerated list of social platforms, so the schema itself carries most of the meaning. The description adds the 'social channel' framing but does not explicitly explain how platform maps to an OAuth provider. With 0% schema description coverage, the description only partially compensates for the missing parameter-level detail.

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 names a specific verb ('Generate') and a concrete resource ('a one-time authorization URL for connecting a social channel'), going well beyond the title. It clearly differentiates this tool from sibling tools like list_connected_accounts, which inspect existing connections rather than initiate one.

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 establishes the essential usage context: the tool produces a URL requiring a separate user-initiated browser authorization step. It does not explicitly name alternatives or state when not to use it, but the interactive flow is clear enough to guide an agent.

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