Handle a tool app OAuth callback

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

Annotations already indicate non-read-only, idempotent, and non-destructive behavior. The description adds the authorization class ('board') as additional context but does not disclose what happens during the callback (e.g., token storage). No contradiction with annotations.

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 concise, consisting of two lines. It is front-loaded with the purpose and provides essential operation details. However, it could be slightly expanded to add behavioral context without losing conciseness.

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?

The description covers the basic purpose and operation but lacks context about the OAuth flow (e.g., that this is a callback endpoint invoked by the browser after user authorization). With no parameters and an output schema, more context would help the agent understand the tool's role.

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?

There are no parameters in the input schema, so the description does not need to add parameter details. The baseline of 4 is appropriate as there is no missing parameter information.

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 it handles a tool app OAuth callback, which is a specific verb and resource. It distinguishes from sibling tools like pc_post_tools_oauth_by_connection_id_start that initiate the OAuth 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?

The description includes the HTTP method and authorization class but provides no guidance on when to use this tool versus alternatives, such as the start tool. The OAuth flow context is not explained.

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