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

With no annotations provided, the description carries the full burden of behavioral disclosure. It explicitly states that the action is read-only and that it never returns credentials, which are critical safety and privacy traits. It does not mention return format or potential side effects, but these are minor given the tool's simplicity.

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 only two short sentences, with the core purpose front-loaded and the behavioral caveat immediately following. Every word earns its place; there is no redundancy or filler.

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 zero-parameter tool with no output schema, the description is mostly complete, but it fails to specify what the tool returns. The phrase 'check whether ... work' implies a boolean or status result, but this is not explicit. An agent would benefit from knowing the return shape to interpret the result correctly.

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 tool has zero parameters and the schema description coverage is 100% (vacuously). Per the rules, the baseline is 4 when there are no parameters. The description adds no parameter semantics because there are none to explain, but it does not neglect anything.

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 a specific verb ('check') and resource ('local Brewfather credentials') along with the intended purpose ('whether they work'). It is immediately distinct from all sibling tools, which are recipe-oriented (list, search, get, preview, apply).

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 implies when to use the tool (to verify credentials) but does not explicitly mention alternatives or exclusions. Since no sibling tool overlaps in function, the usage context is clear enough but lacks explicit guidance on when not to use it or prerequisites.

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