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

With no annotations, the description carries the full burden, yet it only implies read-only behavior through "Return ... policy". It says nothing about auth/permission requirements, whether policy varies per account, caching, or any side effects; only the vague qualifier "SaaS-side" hints at a client-side counterpart.

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?

A single front-loaded sentence with no filler. It is efficient, though the term "target-selection policy" is dense jargon left unexpanded.

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?

An output schema exists, so return values need not be spelled out, and one optional parameter keeps the surface small. Still, for a policy/constraints getter the description gives no sense of what the policy governs or how it should shape subsequent calls.

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?

Schema coverage is 0% and the single file_kind parameter has a default of "video" with no enum or description. The phrase "image/video" implicitly maps to the two possible values of file_kind, which partially compensates, but the default and accepted value set are still undocumented.

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?

States a specific verb ("Return") and a specific resource ("SaaS-side upload and target-selection policy for image/video detect-then-blur anonymization"). It is distinguishable from siblings like get_pricing_policy or encrypt_video, though it does not explicitly name what it is not.

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 sentence states when to call this versus encrypt_image, encrypt_video, or submit_encrypt_job. The purpose implies it is a pre-flight policy lookup before upload/encrypt, but that is inference rather than guidance.

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