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

With no annotations, the description must fully convey behavioral traits. It only mentions testing a sequence, without detailing outcomes (e.g., success/failure reporting), side effects (e.g., console logs or screenshots captured based on parameters), or any destructive or read-only nature. This is insufficient for a complex tool.

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 a single sentence with no wasted words, but it is too succinct to be fully informative. While concise, it sacrifices necessary detail that could be included without significantly increasing length.

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 tool's complexity (5 parameters, 2 required, nested steps object, no output schema), the description is severely incomplete. It omits what the tool returns, how results are presented, and any behavior beyond the basic purpose. The schema and sibling tools do not compensate for this 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?

The input schema has 100% description coverage for all parameters, so the baseline is 3. The description does not add additional meaning beyond what the schema provides, such as constraints or relationships between parameters, but also does not contradict or omit information.

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 states the tool tests a sequence of user actions across multiple pages. It identifies the verb 'Test' and resource 'sequence of user actions across multiple pages', which is specific. However, it does not differentiate from potential sibling tool 'ui_workflow_validator', which may have similar purpose.

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 alternatives or when not to use it. The description lacks any context about prerequisites, suitable scenarios, or exclusions, relying solely on the tool name for inference.

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