Zephyr: Get Test Execution Links

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

Annotations already establish read-only, idempotent, non-destructive behavior. The description adds only the expected output phrase, which is already covered by the output schema, and no additional behavioral context such as pagination, authorization, or error behavior.

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?

Starts with a clear one-line purpose and is organized with headings. However, the Parameters section duplicates the schema, and the 'Expected Output' line is repeated verbatim in both examples, adding redundancy; a minor typo ('oftest') also appears.

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 one-parameter, annotated read-only tool with an output schema, the description covers the essential invocation details with two representative examples. It does not explain what kinds of links are returned or how to handle missing executions, but the output schema and simple API make this a minor gap.

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?

Input schema already documents testExecutionIdOrKey with pattern and format, so schema coverage is 100%. The description repeats this and adds concrete examples of both ID and key forms, which is mildly helpful but not semantically new.

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 opening sentence names a precise action ('Get links') and target ('a specific test execution'), so an agent immediately knows what resource is affected. It differentiates from sibling zephyr_get_test_execution by emphasizing links, though it doesn't explicitly call out alternatives.

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 implies when to use it—whenever links for a known test execution are needed—and groups it under 'Test Executions.' It offers no explicit guidance on when to prefer it over zephyr_get_test_execution or the cycle/case link tools, and no exclusions.

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