get_rates_type

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

No annotations are provided, so the description carries the full burden. It only mentions the default value and that ACTUAL sets center sens and max rate directly. It does not disclose any behavioral traits such as whether the operation is idempotent, requires specific permissions, or has side effects. For a simple getter, this is minimal but not contradictory.

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 two terse sentences. It front-loads the purpose ('Get rates_type') and adds meaningful context about the ACTUAL mode. Every word serves a purpose; no wasted content.

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 simplicity (no params, no output schema), the description mostly explains the tool. However, it omits enumeration of other possible rates_type values beyond ACTUAL, which would help an agent understand the full set of possible return values. It mentions the default but not the full domain.

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 input schema has 0 parameters, so schema description coverage is 100%. According to guidelines, 0 parameters baseline is 4. The description does not add parameter information nor does it need to.

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 'Get rates_type: Rate calculation system.' and explains what ACTUAL means, making the tool's purpose immediately understandable. It distinguishes from sibling tools like set_rates_type by conveying it is a read operation.

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 no explicit guidance on when to use this tool versus alternatives (e.g., set_rates_type). While the naming convention implies a getter, the description fails to state that this is for reading the current configuration, leaving usage context implied.

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