test_generate_edge_cases

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It only restates the core action; it says nothing about whether tests are returned inline or written as files, whether the framework parameter is required or has a default, whether api_key is needed per invocation, or what the output format looks like. These are material unknowns for a generation tool.

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 efficient sentence with the key verb and scope front-loaded. No filler or redundancy. It loses a point only because the brevity comes at the cost of valuable guidance.

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 tool with zero annotations and no output schema, the description is too thin. It omits when to prefer it over test_generate_unit or error_generate_boundary, whether framework is optional or defaulted, and what the tool returns. An agent would have to invoke it blindly to learn these behaviors.

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% — api_key, framework, and source_code are each described in the schema. The description adds no parameter-level meaning beyond what the schema already provides, so it meets the baseline of 3 but does not exceed it.

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 and resource ('Generate edge case and boundary condition tests for source code'), and the edge-case scope differentiates it from siblings like test_generate_unit, test_generate_mocks, and api_generate_tests. It's a meaningful action statement, not a tautology. Minor deduction: it names no sibling explicitly, relying on the scope phrase to do the differentiation work.

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?

No guidance about when to use this tool versus the many adjacent test-generation siblings (test_generate_unit, test_generate_mocks, error_generate_boundary, sct_generate_tests, api_generate_tests) or even data_generate_edge_cases. No context such as 'use when coverage of boundary values like null, empty, min/max is needed.' An agent must infer the use case entirely from the tool name.

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