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

Annotations already declare readOnly, idempotent, non-destructive and closed-world, so the safety profile is covered structurally. The description adds that results are limited to public governed knowledge with per-tenant object types and counts, which is useful scoping context but nothing about pagination or freshness.

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?

One tightly-packed sentence with the resource front-loaded and the return shape appended; no filler. It is slightly dense with internal terminology, which costs a little clarity but not length.

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?

With zero parameters and an output schema present, the description needn't document returns in detail, and it does gesture at the payload. For a simple read-only listing tool the coverage is adequate, missing only a pointer to which sibling to call next.

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 tool takes no parameters, so there is nothing for the description to compensate for; the baseline for zero-parameter tools applies. The description correctly implies an unfiltered enumeration.

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 (Lists) and resource (organizations publishing public governed knowledge) plus what each entry exposes (object types and counts). It's clear what the tool returns, though the jargon 'GVE' is undefined and the differentiation from siblings like list_objects is not made explicit.

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 statement of when to use this tool versus the siblings fetch, get_object, list_objects, or search. The description never mentions alternatives or conditions, so an agent must infer that 'list all tenants' is a discovery/entry-point call.

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