testneo_preview_generated_tests

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

Mentions applying route hardening conditionally, but doesn't clarify if preview is read-only or has side effects; no annotations to compensate.

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?

Two clear, front-loaded sentences with no 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?

Adequate for main purpose but missing details on input format for generated_test_cases and output behavior.

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?

Adds some meaning to route_hardening parameter via description, but neglects generated_test_cases and max_items (0% schema 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 clearly states it previews generated tests in NLP and Playwright SDK spec.ts format for human-in-loop approval, distinguishing it from sibling tools like export or execute.

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?

Implied usage after test generation for approval, but no explicit when-not-to-use or comparison to alternatives like export or update.

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