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

With no annotations, the description carries the full behavioral burden. 'View' signals a read-only operation, and it usefully discloses the return content (version chain + hashes, on-chain verifiability), but it omits permissions/auth requirements, pagination behavior, and what happens if the owner has no policy versions.

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 the core purpose first and the useful parenthetical detail after. No filler or redundancy.

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 explained, and the tool is a simple single-parameter read. However, the owner parameter format and any behavioral constraints are unaddressed, leaving modest gaps for an agent to infer.

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 'owner' parameter is completely undocumented in the schema. The description implies owner is a user identity but gives no format or type expectations (address, DID, user id), so it only partially compensates for the coverage gap.

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 uses a specific verb+resource pair ('View a user's policy version history'), which clearly separates it from siblings like get_policy (current state) and list_policy_requests (pending requests). It does not name a sibling explicitly, but the resource scope is distinctive enough for an agent to route correctly.

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?

There is no statement of when to use this tool versus get_policy or get_audit_trail, and no prerequisites or exclusions. The parenthetical about on-chain verifiability hints at a use case but does not constitute actual usage guidance.

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