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

No annotations are present, so the description carries the full burden. It discloses that credentials are handled and that the request is raw, but it never explains possible side effects, response format, or error behavior. For a tool that can invoke PATCH/DELETE, this is a meaningful gap.

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?

Two short sentences, front-loaded with the core action, and the routing rule is in the second sentence. The included OpenAPI URL is the right pointer-to-spec rather than duplicating endpoint documentation.

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 raw passthrough tool with many possible endpoints, the OpenAPI link provides essential coverage, but the description omits generic invocation details such as what the tool returns, how errors surface, and how body should be supplied for each method. It is adequate but has clear gaps.

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 only 33%, and the description does not compensate. It does not explain how body participates, how path should be formatted beyond the schema pattern, or the significance of method. The OpenAPI link helps but is not inline parameter guidance.

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 precise action: 'Call any REST endpoint of the platform' and names the resource (the platform REST API). It also differentiates itself from sibling domain tools by saying 'Use when no dedicated tool fits.'

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?

It explicitly states the selection condition: use when no dedicated tool fits, which implies avoiding it when a dedicated sibling exists. Although no concrete sibling is named, the generic criterion is unambiguous for a fallback tool.

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