xray_create_test_execution

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

No annotations are provided, so the description carries full responsibility. It only says 'Creates a new Test Execution issue' but does not disclose permission requirements, potential side effects, rate limits, or what the response contains. For a mutating tool, this is a significant transparency gap.

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 only two sentences, front-loaded with the core purpose and immediately followed by usage requirements. Every sentence adds necessary information without redundancy.

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 create tool with no output schema or annotations, the description covers the main intent and parameters but omits return values, error scenarios, and any post-creation side effects. The parameter documentation is complete, but the overall context feels minimally adequate.

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 each parameter is already documented. The description reiterates required vs optional and gives an example for 'fields', but the schema already includes a similar example. Thus it adds minimal value beyond the schema, matching the baseline for full coverage.

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 uses a specific verb ('Creates') and resource ('Test Execution issue in Jira/Xray'), clearly stating the tool's action and output. This distinguishes it from sibling tools like xray_create_test_plan and xray_get_test_execution.

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?

It clearly states required inputs ('Requires a project key and summary') and optional parameters ('description and additional Jira fields'), which helps the agent know prerequisites. However, it does not explicitly mention when to use this over alternatives, though the resource type offsets this somewhat.

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