get_schema

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

No annotations are provided, so the description carries the full burden. It does disclose a key behavioral trait: internal $refs are resolved inline. This goes beyond the schema. However, it doesn't mention error handling, permissions, or what happens when the schema is not found, which would add confidence for an agent.

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 sentences. The first states the core function and the inline-ref detail; the second gives a clear pointer to a related tool. No fluff, information density is high and front-loaded.

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 simple one-parameter get operation with no output schema, the description covers the essential intent, the ref-resolution behavior, and a related alternative. It doesn't specify return shape or error cases, but those are less critical given the tool's simplicity. Slight gap in detail about failure modes prevents a 5.

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 100% for the only parameter ('name' is described with an example). The description's phrase 'by name' aligns with the param but adds no extra semantic detail beyond what the schema already provides. Baseline 3 is appropriate.

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 specific verb ('Get') and resource ('a specific schema from components/schemas by name'), and distinguishes itself from sibling tools like 'get_types' by mentioning conversion. It is clear which tool to use when you need a single named 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?

It explicitly tells the agent to use 'get_types' for TypeScript conversion, which clarifies a distinct use case. However, it does not explicitly contrast with 'search_schemas' (e.g., 'use search_schemas if you don't know the name'), so the 'when not to use' guidance is only implied. Still, the context is clear enough.

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