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

With no annotations provided, the description carries the behavioral burden. It reveals that this is a health/configuration check and that it is free, which implies a low-risk read operation. However, it does not mention side effects, authentication requirements, rate limits, or any special behavior beyond the words 'Free.'

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 exceptionally concise: two short sentences, with the main purpose front-loaded and no filler. The second sentence, 'Free.', is short but provides a distinct piece of information about cost.

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 status check with an output schema, the description is mostly complete. The main lingering ambiguity is what exactly 'configuration' includes and what kind of health information is returned, but the output schema likely covers those details.

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 schema description coverage is 100%, so there is no parameter ambiguity. The baseline for zero-parameter tools is 4, and the description adds nothing harmful or confusing regarding parameters.

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 states a clear verb and resource: 'Check the health and configuration of this service.' This is specific enough to understand the tool's purpose, but it does not explicitly differentiate it from sibling status tools like roastify_session_status or roastify_adoption_status, which are also status-related.

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?

No guidance is given about when to use this tool versus the many sibling status tools. The phrase 'Free' hints at cost, but there is no explicit when-to-use or when-not-to-use instruction, and no alternatives are named.

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