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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description usefully adds that no API key or billing is required and that data comes from OpenStreetMap, but says nothing about result limits, pagination, coverage gaps, or rate 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 text is visibly duplicated and truncated ('...straight from OpenStreetMap: name…. Find local businesses by area and category straight from OpenStreetMap: name, category...'), so the opening is repetitive rather than front-loaded. Wasteful structure undermines readability.

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 output schema, the description does well to enumerate the returned fields (name, category, address, phone, website, coordinates), which is genuinely useful. However, for a scraping tool it omits coverage, rate/limit, and pagination behavior that an agent needs to call it safely.

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?

Only one (nested) parameter exists and schema coverage is nominally 100%, but the schema's own description is a generic pointer to an external URL. The description's mention of 'area and category' is the only real hint at what the input should contain, which is marginal added value.

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?

States a specific verb+resource ('Find local businesses by area and category') and names the data source (OpenStreetMap) plus the returned fields. This implicitly separates it from the Google Maps-flavored siblings, though it never names an alternative outright.

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 phrase 'by area and category' hints at how to query, but there is no statement of when to pick this over google_maps_lead_enricher or google_reviews_insights, and no exclusions or prerequisites. An agent gets a use case, not selection guidance.

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