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

Annotations cover the safety profile (readOnlyHint=false, openWorldHint=true, idempotentHint=false, destructiveHint=false). The description adds behavior the annotations cannot express: the URL is one-time-use and requires a human to open it in a browser and authorize. It stops short of stating URL expiry or the post-authorization flow, but the human-in-the-loop disclosure is genuinely additive.

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 sentences, front-loaded with the core action, no filler. Every clause earns its place by telling the agent what is produced and what the user must do with it.

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?

An output schema exists, so return values need not be explained, and the description correctly focuses on the action and the browser handoff. It is slightly incomplete in not indicating what the agent should do after authorization (e.g., check list_connected_accounts) or how long the one-time URL remains valid.

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 single 'platform' parameter has 0% schema description coverage, and the description never mentions it or explains which platforms are supported. The enum in the schema enumerates the valid values, which carries most of the semantic load, but the description contributes nothing beyond 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?

States a specific verb (generate) and a specific artifact (one-time authorization URL) for connecting a social channel. An agent can distinguish this immediately from siblings like list_connected_accounts or test_blog_connection, which do not produce a connection URL.

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 implies the usage flow by stating the user must open the URL in a browser and authorize, which tells the agent this is a human-in-the-loop step rather than a silent backend call. However, it never names when to prefer this over alternatives or what prerequisite state (e.g., being in the right team/workspace) is needed.

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