get_auth_status

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

Discloses critical behavior: by default no API call, and if validate:true costs 1 rate-limit call. Describes what information is reported. No annotations exist, so description fully carries the transparency burden.

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, no filler. First sentence states purpose and outputs, second sentence explains modes and cost. Efficient and front-loaded.

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?

Covers core status information and optional validation. Lacks mention of error handling or token expiration, but for a simple status check this is adequate. No output schema, but description lists return fields.

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?

The single parameter 'validate' has schema description (100% coverage). Description adds context: what setting it does (verify token) and cost implication, going 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?

Clearly states the tool reports Untappd authentication status, listing specific outputs (token configuration, source, file path, unlocked status). Distinct from sibling tools which are about beer/venue/user data.

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?

Explains when to use (checking auth status) and mentions two modes (free vs validated). Implies this is a diagnostic tool. Doesn't explicitly state when not to use, but context is clear among siblings.

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