Get an approval

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

Annotations already provide readOnlyHint, idempotentHint, destructiveHint, and openWorldHint. The description adds the HTTP method and authorization class, which are not in annotations, but does not disclose behavioral traits like rate limits or data freshness.

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 but includes a redundant title line that echoes the title. It could be more concise by combining the first two lines. The structure is front-loaded but not optimally efficient.

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?

Given the simple input (one parameter) and existence of an output schema, the description provides the basic operation but lacks completeness in explaining the purpose and usage context. It does not mention how to obtain the approval ID or the expected response shape.

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%, and the description does not explain the 'id' parameter or its expected format. The tool requires a path object with an id string, but no semantic context is provided to help the agent construct a valid input.

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 'Get an approval' and specifies the HTTP method and path. However, it does not differentiate from sibling tools like pc_get_companies_by_company_id_approvals or pc_get_approvals_by_id_issues, which could cause confusion about the exact scope.

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 guidance on when to use this tool versus alternatives. It does not mention expected context, prerequisites, or situations where other tools would be more appropriate. The description simply states the operation and authorization class.

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