api_generate_tests

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

Annotations are absent, so the description carries the full burden of behavioral disclosure. It only states that a test suite is generated; it does not say whether files are written to disk, whether existing tests are overwritten, why an api_key is needed, or what the output looks like. For a generation tool with potential side effects, this is a significant 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?

A single front-loaded sentence with the verb and core purpose up front and zero filler. It is appropriately sized, though the brevity exchanges useful behavioral detail for conciseness, which is penalized in other dimensions.

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?

With no annotations, no output schema, and an unexplained api_key parameter, the description is too thin for an agent to invoke this correctly. It leaves output location, overwrite behavior, api_key necessity, and framework handling entirely unstated.

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 67% — api_key is completely undocumented. The description merely paraphrases the source parameter's schema text and adds nothing about api_key or framework. With a third of parameters unexplained, the description should compensate but does not.

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?

States a specific verb (Generate), resource (comprehensive API test suite), and input types (OpenAPI spec, route definitions, endpoint patterns). However, it does not explicitly differentiate itself from overlapping siblings like api_contract_test, test_generate_unit, or clitest_generate_suite, so it stops short of a 5.

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?

Usage context is implied by the listed source types — use this when you have an OpenAPI spec, routes file, or endpoint patterns. But there is no explicit when-to-use or when-not-to-use guidance and no mention of alternatives among the many test-related sibling tools.

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