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

No annotations are provided, so the description carries the full burden. It discloses that the tool generates and downloads a file, which implies a read operation with a side effect of file creation. However, it lacks details on permissions required, rate limits, error conditions, or whether the operation is idempotent. The note about the Government site is useful context but doesn't fully compensate for missing behavioral traits.

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 efficiently structured in two sentences: the first explains the core functionality, and the second provides a critical restriction. Every sentence adds value, with no wasted words or redundant information.

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 (file generation/download), lack of annotations, and no output schema, the description is incomplete. It explains what the tool does but omits details on the output format (beyond '.policy' file), potential errors, or deployment implications. The Government site note is helpful but doesn't fully address the gaps.

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 appropriately focuses on the tool's purpose and usage without redundant parameter details, earning a baseline score of 4 for zero-parameter tools.

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 tool's purpose with specific verbs ('generates', 'downloads') and resources ('Workload Protection policy file', '.policy file'). It distinguishes itself from siblings by focusing on policy file generation and download, unlike other tools that handle creation, deletion, or listing of security rules or policies.

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: to generate and download a policy file from active agent rules for deployment. It includes a specific restriction note for the Government site. However, it does not explicitly mention when not to use it or name alternative tools for similar purposes.

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