invalidate_cache

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

With no annotations, the description carries full responsibility for behavioral disclosure. It only states the action without revealing any behavioral traits such as authorization requirements, side effects, or whether the operation is reversible. This is insufficient for an AI agent.

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 sentence, making it brief. However, it is too sparse given the complexity of the input schema. It sacrifices necessary detail for brevity, earning a middle score.

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?

Without annotations, output schema, or parameter descriptions, the tool description is severely incomplete. It fails to cover return values, the meaning of model/model_id, or the tool's effect on the system, leaving major gaps for the agent.

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 a nested object with two parameters (model and model_id) and 0% description coverage. The tool description does not explain these parameters at all, leaving the agent without guidance on how to populate them correctly.

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 'Invalidate cached query results in Metabase' clearly states the action (invalidate) and the resource (cached query results in Metabase). It is specific but does not differentiate from siblings like 'delete_cache_config' or 'refresh_persisted_model', which might have overlapping functionality.

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 usage guidelines are provided. The description does not indicate when to use this tool versus alternatives, nor does it mention prerequisites, exclusions, or context-specific applicability.

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