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

Despite no annotations, description reveals use of 'Opus 4.8 with live web search and website reading' and lists returned fields (name, what they do, website, country, region). Adds behavioral context beyond basic purpose, though misses potential limitations.

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 only, no fluff. First sentence states action, method, and outputs. Second sentence provides usage order. Efficient and front-loaded for quick comprehension.

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?

For a simple one-parameter tool with no output schema, the description covers purpose, inputs, method, outputs, and usage context. Missing details on error handling or edge cases, but complete enough for effective use.

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% with a clear parameter description. The tool description adds examples ('clubright', 'triibe.ai', 'we sell candles in Austin') but does not surpass the baseline significantly. Adequate but not enhanced.

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's purpose: identify a business from name, website, or phrase. It contrasts with siblings by advising 'Use this first... before going live', distinguishing it from go_live and create_checkout.

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?

Explicitly says 'Use this first to understand who the merchant is before going live', providing clear when-to-use guidance relative to siblings. Lacks explicit when-not-to-use, but context suffices.

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