get_propeller_database

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

The description states it returns a JSON string and that errors are returned as formatted strings, not exceptions. With no annotations, it partially covers behavioral traits but lacks details on data freshness, availability, or performance impact.

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?

Description is extremely concise: two sentences plus a note about exceptions. No redundant information; every sentence adds value.

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 simple parameterless tool with an output schema, the description covers purpose, return type, and error handling. It is reasonably complete given the low complexity.

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 (input schema empty). Schema description coverage is 100% (by default). The description correctly states the resource and return format, which is sufficient for a parameterless tool.

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 uses the verb 'get' and specifies the resource 'propeller database' with geometric and performance data. It clearly distinguishes from sibling tools like propeller_bemt_analysis (which performs analysis) and get_airfoil_database (a different database).

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 explicit guidance on when to use this tool versus alternatives. The description implies usage for retrieving the database, but does not mention when to avoid or compare to siblings like propeller_bemt_analysis.

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