get_features

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

No annotations are present, so the description carries the full burden. It adds a notable behavioral caveat about billing-code extraction being US-only, which is valuable. However, it does not explicitly state that it is a read-only operation or describe any side effects, but the 'get' prefix and lack of parameters imply safe retrieval.

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 a single, front-loaded sentence that begins with the core purpose ('What PatientNotes does') and lists categories without fluff. It efficiently conveys scope and a critical caveat, making every word earn its place.

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?

Given the tool has no parameters, no output schema, and no annotations, the description adequately explains what the tool returns (features grouped by categories) and includes an important regional limitation. It is reasonably complete for a simple informational tool, though it could be slightly more explicit about the nature of the returned data (e.g., a list vs. a narrative).

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 coverage is 100% (trivially, since there is nothing to cover). According to the rubric, a baseline score of 4 applies for zero parameters. The description does not need to compensate for any parameter gaps.

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 the tool's purpose: 'What PatientNotes does' and enumerates the categories of features (documentation, post-note, mobile, team, compliance). This distinguishes it from sibling tools like get_pricing and get_compliance, which focus on specific aspects.

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 implicitly indicates when to use the tool (to learn about tool features) but does not explicitly state when not to use it or reference alternatives. The sibling names suggest alternatives, but no direct guidance is provided.

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