Start a cloud upstream connection

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

Annotations already indicate this is a non-read-only, non-destructive operation. The description adds the authorization class ('board'), providing some behavioral context. However, it does not describe side effects, idempotency, or whether the operation blocks or initiates an async process.

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 very short (two sentences) and avoids verbosity. The first sentence restates the title, which is acceptable but not ideal for front-loading. Still, it is appropriately sized for a simple tool.

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?

Despite having an output schema, the description lacks important context about the connection process (e.g., that this starts an OAuth flow, requires a callback, or that a follow-up 'finish' step is needed). The agent cannot fully understand the tool's role in the broader workflow.

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 input schema has three nested properties (companyId, remoteUrl, redirectUri) with 0% schema description coverage. The description does not explain what these parameters are or how they should be used, leaving the agent unable to infer their purpose.

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 the action ('Start a cloud upstream connection') and provides the HTTP method and path. However, it does not distinguish this from the sibling tool 'pc_post_cloud_upstreams_connect_finish', which is part of the same flow.

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?

There is no guidance on when to use this tool versus alternatives. It does not mention prerequisites (e.g., that an upstream must already exist) or indicate that this is the first step in an OAuth-based connection process.

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