playwright_stats

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

No annotations are provided, so the description must carry the behavioral burden. The verb 'Report' strongly implies a read-only operation, and the description adds context about what is reported (status, counts). This is adequate for a simple stats tool, though it could explicitly state that it makes no changes.

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, concise sentence that front-loads the action ('Report') and specifies both the target ('interactive session's status') and the additional detail ('recorded-entry counts'). No unnecessary words.

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?

The tool has 0 parameters and an output schema, so the description does not need to explain return values. The description covers the essential function adequately for a low-complexity tool, and there are no gaps in parameter or return information.

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 tool has zero parameters, so the description need not explain parameter semantics. The score is at baseline 4 for 0-parameter tools, and the description adds no conflicting 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 a specific verb ('Report') and resource ('interactive session's status and recorded-entry counts'), which distinguishes it from sibling tools like playwright_navigate or playwright_record. It unambiguously identifies this as a status/statistics tool.

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 implies usage when the user needs session status or entry counts, making the context clear. It does not explicitly mention alternatives or exclusions, but the context is sufficiently clear from the description and sibling names.

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