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

readOnlyHint=true already declares the safety profile, and the description adds genuine behavioral detail beyond that: "active" is defined as only roots containing entries, which tells the agent results are filtered rather than a full dump. It stops short of mentioning pagination, ordering, or empty-result behavior, so it is not a 5.

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?

Two short sentences with the purpose front-loaded and the filtering semantics immediately after; every clause carries information and there is no boilerplate.

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 simple read-only list tool with no output schema, the omissions are narrow but real: the undefined `target` parameter and the absence of any hint about result shape or ordering. Annotations cover safety, so the description is nearly complete, but a caller still cannot predict what passing `target` does.

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?

There is a single optional parameter, `target`, and schema description coverage is 0% - the schema gives only a type and null default with no meaning. The description never mentions what a target is or how supplying one changes the listing, so the agent must guess whether it scopes to an account, region, or root ID.

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?

"List all active security roots" gives a specific verb (list) and resource (security roots), and the read tag plus the use of "active" scopes it against mutation-oriented siblings like create/update/delete security root tools. An agent can tell what this returns without opening the schema.

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 verb "List" implies an inventory/read use case, so context is reasonably inferred, but there is no explicit when-to-use statement, no mention of prerequisites or permissions, and no named alternative such as the tool for fetching a single root by ID.

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