Get a schema

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

With no annotations, the description carries the full burden, and it does disclose a real behavioral trait beyond the schema: that $refs are inlined rather than left as references, which affects how the agent consumes the result. It still omits error behavior for unknown names and says nothing about caching, but for an obvious read lookup this is solid disclosure.

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?

Purpose and the key $refs-inlining detail are front-loaded before the name list. The long enumeration is verbose but functional, since it substitutes for the missing schema documentation; it earns its space rather than being filler.

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?

There is no output schema or annotations, so the description must stand alone; it covers the parameter domain completely and characterizes the return value ('JSON schema ... with $refs inlined'). Only error/edge-case behavior on an invalid name is left unaddressed, which is minor for a simple read lookup.

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 schema only declares name as a bounded string, but the description compensates by fully enumerating the 48 valid component names, effectively supplying the enum the schema lacks. It does not clarify any name semantics beyond the self-descriptive identifiers.

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 and resource ('One JSON schema from the API components') and adds a meaningful qualifier ('with $refs inlined') that distinguishes it from sibling lookups like get_endpoint, get_page, or get_example. An agent can immediately tell what it retrieves without opening the schema.

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 purpose implies when to use it (you need a named component schema), but the description offers no explicit when/when-not guidance or alternative routing (e.g., vs get_endpoint or search_guide). Usage is inferable from the name and enumeration rather than stated.

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