Search Untappd breweries

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

Annotations already declare readOnlyHint and idempotentHint, so the 'Read-only' sentence adds no new safety information. However, the description adds useful behavioral context beyond the annotations by specifying what a match contains and that this is a lightweight search step before fetching full brewery detail.

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?

Three focused sentences with the core action first and the follow-up routing last. The only redundancy is 'Read-only', which duplicates the readOnlyHint annotation already present.

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 search tool with one required parameter and no output schema, the description gives enough return-value detail and next-step guidance. It could additionally mention pagination behavior, but the limit/offset fields are already documented in the schema.

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 description coverage is 100%, and the input schema already documents 'query', 'limit', and 'offset' clearly. The description only restates that the search is by name and does not add parameter-level meaning beyond the schema.

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 action and resource: search Untappd for breweries by name. It also describes the returned fields (brewery id, location, type, beer count) and explicitly routes the caller to untappd_brewery_info for full detail, which differentiates it from sibling tools like untappd_search_beer and untappd_brewery_info.

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 makes clear this is the search-by-name entry point and that a brewery id should then go into untappd_brewery_info. It does not explicitly state when to choose this over untappd_search_beer, but the brewery-specific wording and follow-up routing provide clear context.

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