getWorkItemTestParameterDefinitions

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

No annotations are provided, so the description must convey behavioral traits. It only states it 'returns a list' without mentioning side effects, rate limits, error handling, or behavior of pagination parameters (page_size, page_number). The return format is not described, and the description does not add value beyond what annotations would provide.

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 concise sentence that efficiently conveys the core purpose. It is front-loaded and free of fluff. However, it could be slightly more informative without sacrificing brevity, e.g., mentioning the list nature or required parameters.

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 complexity (7 parameters, no output schema, no annotations), the description is insufficient. It does not explain the return type or structure, pagination behavior, or implications of optional parameters like 'fields' and 'include'. It relies heavily on schema descriptions, which may not be adequately parsed by agents.

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?

All 7 parameters have descriptions in the input schema (100% coverage), so the baseline is 3. The tool description does not add any additional meaning beyond the schema descriptions. It does not clarify how parameters interact or provide usage examples.

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 clearly states 'Returns a list of Test Parameter Definitions for the specified Work Item,' specifying verb (returns), resource (test parameter definitions), and scope (for a work item). It implicitly distinguishes from siblings like 'getProjectTestParameterDefinitions' and 'getWorkItemTestParameterDefinition' (singular) but does not explicitly differentiate.

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 vs. alternatives. No mention of when-not-to-use, prerequisites, or context. The description simply states what it does without contextualizing its use among siblings like 'getProjectTestParameterDefinitions' or 'getWorkItemTestParameterDefinition'.

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