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

No annotations are provided, so the description carries the full burden. 'Validate' implies a read-only or check operation, but it doesn't disclose whether this performs a dry-run, returns validation errors, requires specific permissions, or has side effects (e.g., caching). The description lacks behavioral details needed for safe and effective use in a zero-annotation context.

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, efficient sentence with no wasted words. It's front-loaded and appropriately sized for a simple tool, though its brevity contributes to gaps in other dimensions. Every word serves a purpose, earning a high score for conciseness.

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 name suggests validation (potentially complex logic), no annotations, no output schema, and 0 parameters, the description is inadequate. It doesn't explain what validation means, what the output might be (e.g., success/failure, error details), or how it fits into the workflow. For a validation tool in a security monitoring context, more context is needed.

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 with 100% coverage (empty object), so the schema fully documents that no inputs are required. The description doesn't add parameter details, but with zero parameters, the baseline is 4 as the schema already provides complete information. No compensation is needed.

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 'Validate a suppression rule' restates the tool name (which contains 'validations') without adding specificity. It doesn't clarify what validation entails (e.g., syntax check, compliance verification, pre-creation validation) or what resource is being validated beyond the generic 'suppression rule.' This is essentially a tautology that provides minimal additional insight beyond the name.

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 guidance on when to use this tool versus alternatives. Given sibling tools like 'create_security_monitoring_configuration_suppressions' and 'create_security_monitoring_configuration_suppressions_rules', it's unclear whether this validation is a prerequisite, a standalone check, or serves a different purpose. No context, exclusions, or alternatives are mentioned.

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