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

With no annotations, the description carries the behavioral burden and does disclose the important flow: returns a hosted-auth URL, user completes OAuth in browser, no password/cookie needed, and the connection is confirmed asynchronously via webhook. It omits details such as URL expiry/single-use behavior, auth requirements for calling the tool itself, and error cases.

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 purpose is front-loaded in the first sentence after the repeated title, and the OAuth flow is described efficiently. The response boilerplate (200 content-type) is minor standard noise but does not obscure the useful content.

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 zero-parameter tool with no output schema, the description covers what the tool returns and how the user completes the flow. It is not fully complete because it lacks explicit sibling selection guidance and does not describe the response body beyond a 200 status/content type.

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 tool takes zero parameters, so there is no parameter semantics burden; the baseline for a parameterless tool is 4. The schema coverage note is not relevant because there are no inputs to document.

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 verb and resource: get a Unipile hosted-auth URL to connect LinkedIn. It distinguishes the mechanism from credential-based siblings by saying no password or cookie is needed, though it never names those sibling tools explicitly.

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?

It explains the hosted OAuth flow and implies this is the no-credentials path, but it does not explicitly say when to use this instead of connect_linkedin_credentials, connect_linkedin_li_at, or connect_linkedin_checkpoint_mcp. For an agent choosing among several LinkedIn-connection tools, that routing guidance is only implied.

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