getWorkItemTestParameterDefinition

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

With no annotations, the description must convey behavioral traits. It only states 'Returns' with no mention of side effects, authorization needs, or that it is a read-only operation. This minimal transparency leaves the agent uninformed about whether the operation is safe or destructive.

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 front-loads the verb. It is efficient but could benefit from a brief expansion to include key context without losing conciseness.

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 no output schema and 6 parameters, the description is incomplete. It does not describe the return value beyond 'Test Parameter Definition', nor does it mention the optional parameters (fields, include, revision) or their purpose in relation to the request.

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 coverage is 100%, so the description does not need to add much parameter info. However, it adds no additional meaning beyond the schema, such as explaining what a test parameter definition is or how testParamId relates to workItemId. Baseline of 3 is appropriate.

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 it returns a specific test parameter definition for a given work item, using a verb and specifying the resource. However, it does not explicitly distinguish itself from similar sibling tools like getWorkItemTestParameterDefinitions (plural) or getProjectTestParameterDefinition, though the required testParamId implies singularity.

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, nor does it mention any prerequisites or exclusions. For instance, it does not note that getWorkItemTestParameterDefinitions lists all definitions for a work item.

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