Get Untappd distinct beers

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

Annotations already declare readOnlyHint, idempotentHint, and openWorldHint. The description adds 'Read-only' for clarity but does not disclose further behavioral traits such as data freshness or pagination limits (though limit is in schema). No contradictions with annotations.

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 very concise at two sentences, front-loaded with the main purpose, and contains no superfluous information. Every sentence serves a purpose.

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 read-only tool with no output schema, the description sufficiently describes what is returned (distinct beers with rating and count). Sorting and paging are mentioned. Could note error handling or empty results, but overall adequate given schema richness.

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%, so the baseline is 3. The description adds minimal value beyond the schema: it notes sorting/paging support and the username omission hint, which are already implied by field descriptions. No deep semantic enhancement.

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 it retrieves distinct beers a user has checked in, with rating and count. This verb+resource definition is specific and distinguishes it from siblings like untappd_user_checkins (individual checkins) and untappd_beer_info (single beer details).

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 provides basic usage context like omitting username for own account and supporting sorting/paging, but does not explicitly state when to use this tool versus alternatives from the sibling list. No exclusion criteria or when-not-to-use guidance is given.

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