Oura Cache Status

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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint. The description adds context about the local SQLite cache and its enabling conditions, but does not detail what the output contains or error scenarios, which is acceptable given the low complexity.

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 sentences, front-loaded with the core purpose, and every sentence adds value. No wasted words.

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?

The description covers the basic purpose and enabling conditions, and an output schema exists to define return values. However, it does not explain the parameter or what 'status' means (e.g., enabled/disabled, cache size), leaving minor gaps.

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 one parameter (response_format) with an enum but no schema description. The tool description does not explain this parameter or its effect, leaving the agent to infer its meaning from the enum values alone. With 0% schema coverage, the description should compensate.

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 'Show optional local SQLite cache status,' which clearly identifies the action (show) and resource (cache status). It distinguishes from sibling tools that mostly retrieve data or manage connections, but could be more specific about what aspects of status are reported.

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 the tool is used to check cache status, and mentions enabling conditions, but does not explicitly specify when to use this tool versus alternatives or mention any prerequisites or caveats.

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