invariance_eval_suite_get

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

The annotations already declare readOnlyHint=true and openWorldHint=true, so the description adds no behavioral traits beyond those. It does not mention response shape, error cases, or any operational nuance that would help an agent invoke the tool correctly.

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 a single precise sentence with no filler or redundancy. It is efficiently front-loaded and conveys the core operation in minimal words.

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 an extremely simple read-only getter with one required id parameter, the description is minimally viable. However, no output schema exists and the description does not clarify return values or failure behavior, so there are clear but minor completeness 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 0%, and the description only says 'by ID' which only restates that the id parameter references an eval suite. No format, source, or additional meaning is provided. The description does not compensate for the missing schema documentation.

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 clear action and resource: 'Get an eval suite by ID'. The phrase 'by ID' pinpoints the exact lookup semantics and separates it from siblings like list/create. It does not explicitly contrast with eval_suite_list, but the direct-ID lookup is unambiguous enough for a read-only getter.

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 guidance on when to use this tool instead of list/eval datasets or other getters. An agent can infer basic usage from 'by ID', but exclusions, alternatives, and prerequisite context are absent.

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