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

No annotations are provided, so the description carries full burden for behavioral disclosure. 'Create' implies a write/mutation operation, but the description doesn't mention permissions required, whether this is idempotent, what happens on conflict, or what the response contains. For a creation tool with zero annotation coverage, this leaves significant behavioral gaps, though the basic action is clear.

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 appropriately sized for a zero-parameter tool and gets straight to the point without unnecessary elaboration. Every word earns its place in conveying the core purpose.

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?

For a creation tool with no annotations, no output schema, and no parameters, the description is minimal but inadequate. It doesn't explain what a 'monitor configuration policy' entails, what fields might be configured, or what the expected outcome is. While the zero-parameter count reduces complexity, the description should still provide more context about what's being created and why.

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% schema description coverage, meaning there are no parameters to document. The description doesn't need to explain any parameters, which is appropriate. A baseline of 4 is justified since there are no parameters requiring semantic explanation beyond what the schema provides.

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 'Create a monitor configuration policy' clearly states the action (create) and resource (monitor configuration policy), which is specific enough to understand the basic purpose. However, it doesn't distinguish this tool from similar sibling tools like 'create_monitor' or 'create_monitor_v1', leaving ambiguity about what differentiates a 'monitor policy' from other monitor-related creations.

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. With numerous sibling tools including 'create_monitor', 'create_monitor_v1', 'create_monitor_notification_rules', and 'create_restriction_policy', there's no indication of when this specific tool is appropriate versus those other options. The agent receives no usage context.

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