Start an OAuth connect flow; returns the authorize URL to open

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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds that the tool returns an authorize URL to open, which is useful behavioral context, but omits important flow details like the need for user interaction and the subsequent callback.

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 a single front-loaded sentence with no wasted words. The key verb, resource, return value, and endpoint are all stated compactly.

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 one-parameter tool, the description covers purpose and return value, but it lacks parameter explanation, usage guidance, and flow context. Given the missing output schema and 0% parameter coverage, a complete definition should say more about the platform argument and the OAuth sequence.

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 0%, so the description must compensate. It only embeds '{platform}' in the endpoint path without explaining the platform parameter, its required status, or what the enum values represent, adding no meaning beyond the schema.

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: 'Start an OAuth connect flow; returns the authorize URL to open'. This distinguishes it from most siblings like connections_list or connections_create, though it does not explicitly contrast with connections_oauthCallback or connections_createWithCredentials.

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?

No when-to-use guidance is provided. The description does not mention alternatives such as connections_createWithCredentials or the required follow-up call to connections_oauthCallback, leaving the agent to infer the full flow from tool names alone.

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