unitTestEvaluation

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. 'Evaluates unit test results' gives no indication of whether this is a read-only operation, what permissions might be required, whether it modifies data, what the output format is, or any side effects. For a tool with two parameters and no output schema, this lack of behavioral context is a significant gap that leaves the agent unable to predict the tool's effects or requirements.

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?

While technically concise with just three words, the description is under-specified rather than efficiently informative. It fails to front-load critical information about the tool's purpose or usage. In conciseness scoring, brevity without substance doesn't earn high marks—the description wastes its limited space on a tautological statement rather than providing value.

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?

Given the tool's complexity (2 parameters, no annotations, no output schema) and the rich ecosystem of sibling tools, the description is completely inadequate. It doesn't explain what 'evaluation' entails, what results are returned, how it differs from related testing tools, or any behavioral characteristics. For a tool that presumably analyzes test outcomes, this minimal description leaves too many unanswered questions for effective agent use.

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%, with both parameters ('clas' and 'flags') documented in the schema. The description adds no additional parameter information beyond what the schema already provides. According to the scoring rules, when schema coverage is high (>80%), the baseline score is 3 even with no parameter details in the description. The description doesn't compensate for any gaps, but none exist in the 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 'Evaluates unit test results' is a tautology that essentially restates the tool name 'unitTestEvaluation' without adding meaningful specificity. It doesn't specify what kind of evaluation is performed (e.g., analyzing test coverage, checking pass/fail status, generating reports) or what resources are involved. While it includes a verb ('evaluates') and object ('unit test results'), it lacks the detail needed to distinguish this tool from potential alternatives like 'unitTestRun' or 'unitTestOccurrenceMarkers'.

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 description provides no guidance on when to use this tool versus alternatives. It doesn't mention prerequisites (e.g., needing to run tests first with 'unitTestRun'), context (e.g., after test execution), or exclusions (e.g., not for creating tests). With sibling tools like 'unitTestRun' and 'unitTestOccurrenceMarkers' present, the absence of any comparative guidance leaves the agent guessing about appropriate usage scenarios.

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