getProjectTestParameterDefinition

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

No annotations provided. The description only says 'Returns' without disclosing behavior such as idempotency, side effects, permissions needed, or whether it is a read-only operation. For a retrieval tool, this is acceptable but minimal; more context on response format or constraints would improve transparency.

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?

Single sentence, no filler. All words are necessary. Efficiently states the function.

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?

No output schema, no annotations, and the description does not explain return values, pagination, error conditions, or the effect of the 'fields' and 'include' parameters. Given the tool has 4 parameters including a nested object and optional fields, the description is insufficient for an agent to fully understand the response and usage.

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%, meaning all parameters are described in the input schema. The description adds no additional meaning beyond what the schema provides. Baseline score of 3 is appropriate as the schema does the heavy lifting.

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?

Description clearly states the tool returns a specific Test Parameter Definition for a given project. This distinguishes it from sibling tools like getProjectTestParameterDefinitions (which returns a list) and getWorkItemTestParameterDefinition (which is for work items). The verb 'Returns' and resource 'Test Parameter Definition' are precise.

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 explicit guidance on when to use this tool vs siblings. The description implies it is for retrieving a single definition by ID, but it does not mention alternatives like getProjectTestParameterDefinitions for listing or getWorkItemTestParameterDefinition for work-item scope. The usage context is implied but not clarified.

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