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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint, so the safety profile is covered. The description adds 'public' and specifies the content (capability and governance boundary), which provides some context beyond annotations. However, it doesn't disclose any other behavioral traits like response format or rate limits. With annotations present, a 3 is appropriate.

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?

The description is a single sentence with no filler. The core purpose is front-loaded: 'Return GAIP's public read-only capability and governance boundary.' Every word earns its place, making it highly concise and structured.

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 zero-parameter, no-output-schema tool with annotations covering safety, the description is sufficient. It states the purpose clearly and the scope. It could elaborate on what 'capability' includes, but that's a minor gap given the tool's simplicity and the presence of sibling tools that cover specific aspects.

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 has zero parameters, so the input schema is trivially complete at 100% coverage. The description need not explain parameters, and the baseline for 0 params is 4. The description adds nothing about parameters, but none exist, so this score is fair.

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 states the verb 'Return' and the specific resource: GAIP's public read-only capability and governance boundary. This clearly distinguishes it from sibling tools like gaip_get_governance_limits, which focuses on limits, and gaip_get_identity_and_registry_status, which covers identity/registry. The scope is explicit and actionable.

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 guidance is provided on when to use this tool versus its siblings. The description only states what it does, without mentioning alternatives or conditions that would select it over gaip_get_governance_limits or other getters. An agent would have to infer usage from the name alone.

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