Generate Playwright Repro

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

It adds substantial behavior beyond the destructiveHint annotation: it states the exact write location, mandates a relative outputPath, requires overwrite:true to replace existing files, and explicitly discloses that no outbound network request occurs. This safely frames a destructive write 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?

Two sentences carry the full message: the first front-loads the primary action and inputs, and the second adds the critical constraints. No filler or repetition.

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?

Although there is no output schema, the description covers the key operational risks: destination, relative path, overwrite behavior, and lack of network access. It does not describe the return value or whether outputPath has a default, but the missing details are minor relative to what is provided for a moderately complex, destructive tool.

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?

With 0% schema description coverage, the description must compensate for all six parameters. It does clarify url/goal/finding as alternative input sources and gives explicit constraints for outputPath and overwrite, but it leaves testName and the internal structure of the finding object unaddressed.

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 opens with a specific verb and resource: 'Generate a minimal Playwright test...' and clearly names the output destination. It distinguishes itself from siblings like run_playwright_test by making clear it writes reproductions rather than executing them, and lists the three accepted input forms (scan finding, URL, plain-English goal).

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?

The description provides clear context for when to use the tool: when the goal is to generate a reproduction from a finding, URL, or plain-English goal. It does not explicitly name alternative siblings or state when not to use it, so it stops short of full exclusionary guidance.

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