Add execution attachment

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

With no annotations, the description carries full responsibility for disclosing behavioral traits. It only mentions 'logs, screenshots (base64)' which hints at content encoding but does not state whether attachments are appended, overwritten, or subject to permissions. No side effects or return behavior are described, making this minimal.

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 extremely brief and to the point, with no wasted words. However, it is under-specified rather than efficiently structured; it reads more like a stub than a well-crafted summary. It occupies the middle ground between appropriately concise and inadequately sparse.

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 the simple tool (3 required params, no output schema), the description is too thin to fully guide selection and invocation. It lacks usage context, behavioral details, and any mention of validation or response. The schema covers parameter mechanics but not the operational context needed for correct use.

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%, with each parameter having a clear description. The description adds examples of use cases ('logs, screenshots') that relate to filename and b64content, but this is marginal beyond the schema. It does not elaborate on parameter relationships or additional format specifics.

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 identifies the tool as adding an attachment to a test execution, distinguishing it from sibling attachment tools for cases, plans, and runs. The examples 'logs, screenshots (base64)' give concrete context about intended content. It could be more explicit with 'adds' but the verb+resource is evident.

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 provided on when to use this tool versus the many sibling attachment tools (e.g., kiwi_case_add_attachment, kiwi_run_add_attachment). The description does not mention exclusions or alternative tools, leaving the agent to infer context solely from the 'TestExecution' prefix.

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