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

With no annotations, the description carries full burden but only states the basic action. It lacks behavioral details such as whether this is a read-only operation, error handling for invalid IDs, authentication requirements, or rate limits, leaving significant gaps for a tool that likely fetches sensitive configuration data.

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 that directly states the tool's purpose without any fluff. It's appropriately sized and front-loaded, making it easy to understand quickly.

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 complexity (likely a read operation fetching configuration data) and lack of annotations or output schema, the description is incomplete. It doesn't cover behavioral aspects, return format, or error conditions, which are crucial for effective use in an AI agent context.

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, so no parameter documentation is needed. The description mentions `policy_id` to clarify the retrieval mechanism, adding context beyond the empty schema, which is helpful but minimal since there are no actual parameters to describe.

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 ('Get') and resource ('a monitor configuration policy'), specifying it retrieves by `policy_id`. It distinguishes from siblings like 'get_monitor' or 'get_monitor_policies' by focusing on a single policy via ID, though it doesn't explicitly contrast them.

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 on when to use this tool versus alternatives is provided. It doesn't mention prerequisites like needing a valid policy_id or when to choose this over 'get_monitor_policies' for listing multiple policies, leaving usage context unclear.

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