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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the description doesn't need to restate those traits. It adds the return focus on activation states and blockers, but says nothing about auth requirements, rate limits, caching, or additional behavioral caveats; the word 'truthful' is not operationalized.

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 tight sentence with a front-loaded verb and object. The adjective 'truthful' is slightly vague and could be considered filler, but overall the structure is efficient and readable.

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 strong safety annotations, the enumeration of activation states and blockers gives the essential semantic content. It lacks return format or error details, but for a simple status read this is close to sufficient.

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 and schema description coverage is 100%, so there is no parameter-semantics burden on the description. Baseline 4 applies because there is nothing to clarify.

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 the specific verb 'Return' and enumerates precise resources: A2A, MCP, Entra Agent ID and ERC-8004 activation states and blockers. It clearly states what the tool does, but does not explicitly distinguish itself from sibling getters like gaip_get_capabilities or gaip_get_shadow_status.

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 intended usage is implied by the tool name and return content: an agent would infer to use it when identity/registry activation status is needed. However, there is no explicit when-to-use, when-not-to-use, or comparison to sibling tools, leaving routing partly to inference.

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