get_api_schema

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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds that the schema source is 'separately downloaded' and 'verified' (i.e., local and pre-vetted rather than live-fetched), which is genuinely useful context. It says nothing about behavior for an unknown component name or about how stale the local copy might be.

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 compact, front-loaded sentences with no filler; the core purpose comes first and the parameter hints follow. The only cost is the dense, slightly opaque qualifier 'separately downloaded, verified'.

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 two-parameter read tool with no output schema, the safety and locality context is adequate, and the schema enum documents the allowed operations. Missing are the shape of the returned schema and how to obtain a valid 'component' value, which an agent needs to call this successfully on the first try.

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 has to carry parameter meaning, and it partially does: it clarifies that 'component' must be an exact schema name, which the bare string schema does not convey. It restates the operation enum values without explaining what each operation implies, and it never says how an agent discovers valid component names or that component is optional.

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 gives a specific verb+resource: it reads a v2 request/response schema (not data, not a guide). That is distinguishable from payload-validating or example-generating siblings. It stops short of naming those siblings or stating exactly what artifact is returned, plus the phrasing 'separately downloaded, verified' is slightly cryptic.

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 when-to-use or when-not-to-use guidance and no named alternatives among get_integration_guide, validate_order_payload, or explain_api_error, which are the obvious adjacent choices. The agent must infer that this is the schema-lookup step before building a payload.

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