Create a connection from a platform and credentials (201); write-only

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

Beyond the annotations, the description discloses important write behavior: the operation is not executed unless confirm is true, and there is no server-side dry run. It does not cover broader behavior such as authentication requirements or the exact success response, but it materially improves safety awareness for a write tool.

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 short, front-loaded, and every sentence contributes useful information. The endpoint, write-only nature, confirmation requirement, and lack of server-side dry run are all stated without unnecessary wording.

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 write tool with a nested body, a large platform enum, and no output schema, the description provides the key operational context: confirm-to-execute and no server-side dry run. It could say more about the success response or credentials handling, but the schema and annotations cover enough that the definition is largely complete.

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 coverage is 67%, so the schema carries much of the parameter documentation burden. The description adds meaning by naming platform and credentials and by emphasizing confirm: true, but it omits the required label field and does not explain the credentials object or idempotencyKey beyond what the schema already says.

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 clearly states a specific verb and resource: create a connection from a platform and credentials, and identifies the POST endpoint. It is clear on its own, but it does not distinguish itself from close siblings such as connections_createWithCredentials or connections_oauthStart, which can matter in this tool family.

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 explains the confirmation gate but gives no explicit guidance on when to use this tool versus alternatives. With siblings like connections_createWithCredentials and connections_oauthStart present, the lack of routing guidance is a meaningful gap.

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