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

The annotations already supply destructiveHint=true and idempotentHint=true, so the description only needs to add context rather than re-state safety facts. It does add the 'pending sent' scope, which clarifies the operational target. However, it provides no extra behavioral details such as side effects, reversibility, or permission requirements, so it remains minimally transparent.

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 definition is a single six-word sentence, front-loaded with the action and the exact object. Every word adds meaning, with no fluff or 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?

For a simple two-required-parameter tool, the description, combined with full schema coverage, an output schema, clear annotations, and this is complete enough to invoke correctly. It does not explain why you might withdraw an invitation or what happens afterwards, but the annotations and schema already cover observable behavior, so no major gap remains.

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?

Schema description coverage is 100%, and each parameter already has a clear description (account_id, linkedin_id_or_url, idempotency_key). The tool description itself adds no parameter-level meaning, leaving the baseline of 3 appropriate because the schema fully documents parameters.

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 uses a specific verb ('Withdraw') and a concrete resource ('pending sent connection request'). The 'sent' qualifier distinguishes this from received-invitation actions like accept_invitation and decline_invitation, and from connection-management tools like remove_connection. An agent can tell exactly what this 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 gives no guidance on when to use this tool versus its siblings. It does not mention that it applies to invitations sent by the user, nor does it suggest checking list_sent_invitations first or coordinating with accept_invitation/decline_invitation. The agent is left to infer usage from the name and context.

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