Zephyr: Get Test Execution

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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is clear. The description adds no behavioral context beyond the parameter format and examples; it does not mention response behavior, error cases, or any side effects, though none are expected for a read-only get operation.

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 well-structured with clear sections for parameters and examples, and it is appropriately compact for a one-parameter tool. The repeated 'Expected Output: The test execution with its details' lines are somewhat redundant and add little 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?

For a simple, read-only, single-parameter fetch tool, the definition is largely complete: the schema covers the parameter, annotations cover the behavioral safety profile, and an output schema exists. The examples clarify both supported identifier formats, leaving no critical gap for correct invocation.

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% and the schema includes the same parameter description plus a regex pattern. The description adds two concrete examples using an id ('1') and a key ('PROJ-E123'), which is helpful, but it does not provide meaning beyond what the schema already conveys.

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 states a specific verb ('Get details'), the resource ('test execution'), and the lookup mechanism ('specified by id or key'), making the tool's purpose clear. It does not explicitly name sibling tools like zephyr_get_test_executions, but the singular resource and the id/key qualifier distinguish it well enough.

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 guidance is given about when to use this tool versus alternatives such as zephyr_get_test_executions (the plural listing tool). The intended use is only implied by the parameter name and examples, and there is no mention of exclusions or conditions.

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