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

No annotations are provided, so the description carries the full burden. It does disclose genuinely useful behavior: the output shape (structured places with coordinates/phones/ratings) and a machine-payment cost (0.015 USDC on Base). It omits permission/auth mechanics for x402 payment, rate limits, pagination, and error behavior.

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 Trigger/Input/Output framing is front-loaded and scannable, and each section earns its place. It is slightly over-labelled but has no filler prose.

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?

With no annotations and no output schema, the description must carry the load. It covers purpose, inputs, and outputs, but leaves the payment mechanism (how the x402 USDC charge is settled), result caps, and failure modes undescribed for a paid scraping 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?

Schema coverage is 100%, which sets a baseline of 3, but the description adds real value beyond the schema by stating that 'limit' defaults to 10 and giving a concrete example query format ('coffee shops in Austin'). The schema only says 'e.g. 10' without establishing a default.

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 names a specific verb+resource ('Google Maps Local Business & Reviews Scraper') and enumerates the data returned (addresses, ratings, phone numbers, coordinates). This is clearly distinguishable from generic siblings like google_search and review_analyzer, though no sibling is named explicitly.

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 'Trigger' sentence gives an explicit when-to-use condition: agent searches for local physical businesses, addresses, ratings, phone numbers via Google Maps. It does not, however, state when NOT to use it or name alternative tools (e.g. google_search for general web results).

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