enforce_denies

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

No annotations are present, so the description carries the full burden of behavioral disclosure. It only states what is counted without explaining whether this is a read-only operation, how the 'window' is defined, or what 'Enforced' means in contrast to preview.

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 short phrase, but it is under-specified rather than concise. It omits critical context needed to invoke the tool correctly, so the brevity is not a strength.

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?

Despite having only one parameter and an output schema, the description is too sparse to provide a complete picture of the tool's behavior. It does not clarify key terms like 'window' or 'Enforced', making it inadequate for confident tool selection and invocation.

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 has one parameter (since_hours) with 0% description coverage, and the description does not mention it at all. The meaning and effect of the parameter are completely unexplained.

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 mentions the resource (Cloud Armor rule priority) and metric (enforced DENY counts), but lacks a clear verb and the phrase 'over the window' is ambiguous. It distinguishes from sibling 'preview_denies' via the word 'Enforced', but not explicitly.

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 guidance is provided on when to use this tool versus alternatives like preview_denies or health_check. There is no mention of appropriate use cases, exclusions, or conditions for selection.

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