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

Annotations already declare readOnlyHint, idempotentHint, and non-destructive behavior; the description is consistent and adds meaningful behavioral detail: per-role listing, inferred license tiers, and surfacing orphan duties/privileges. It does not describe output format or scale, but for a read-only report generator this is a reasonable disclosure level.

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?

Three concise sentences with no filler. The purpose is front-loaded, the report contents are listed efficiently, and the orphan-detection behavior is a distinctive final sentence. Every sentence contributes 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 moderate complexity, high schema coverage, and strong annotations, the description is nearly complete: it defines the deliverable, its contents, and a unique behavioral feature. It does not explain the return format or limits, but this is a minor gap since the report nature is clear.

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 description coverage is 100%, so the parameters are already documented. The description does not add extra semantic meaning about how filterModel or maxRolesDetail influence the report beyond the schema. This meets the baseline but adds no additional value.

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 opens with a specific action and resource: 'Generate a security & licensing governance report.' It then details the report contents (duties, privileges, entry points, inferred license tier, orphan duties/privileges), which clearly distinguishes it from security-related siblings like get_security_coverage_for_object and trace_role_license_tree.

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 explicit guidance is given for when to choose this tool over related security/reporting siblings. It does not mention prerequisites, conditions, or alternatives such as get_security_coverage_for_object or trace_role_license_tree. The intended use is implied by the description but not stated.

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