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

With no annotations provided, the description carries the full burden of behavioral disclosure. It states the tool 'clears' cached data, implying a destructive operation, but doesn't specify whether this is reversible, requires permissions, has side effects, or provides confirmation. For a mutation tool with zero annotation coverage, this leaves significant gaps.

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 concise sentences with zero waste. The first sentence states the action and target, while the second provides usage context—both sentences earn their place efficiently.

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's moderate complexity (a destructive operation with one parameter) and no annotations or output schema, the description is adequate but incomplete. It explains the purpose and usage context but lacks details on behavioral implications (e.g., effects, safety) that would be needed for full understanding.

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 schema description coverage is 100%, with the parameter 'target' fully documented in the schema (including enum values and description). The description mentions 'specs and/or generated test cases' which aligns with the schema but doesn't add meaningful semantics beyond what's already structured.

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 verb ('clear') and resource ('cached specs and/or generated test cases'), making the purpose unambiguous. However, it doesn't explicitly distinguish this tool from its siblings (like 'analyze_endpoint' or 'validate_spec'), which would require a 5.

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 clear context for when to use this tool ('when the spec has been updated and needs to be reloaded'), which is helpful guidance. It doesn't specify when NOT to use it or name alternatives among siblings, preventing a score of 5.

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