GAIP Integration & Protocol Agent

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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the safety profile is covered. The description adds real behavioral context beyond them: GAIP fetches, validates and reach-tests the supplied URL, and VERIFY_BEFORE_CALL inspects counterparty evidence. It does not disclose rate limits, failure modes, or what a failed conformance check looks like, and the read-only annotations sit in some tension with the stated network fetch.

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 dense sentences, front-loaded with the usage trigger and followed by the input requirement and the mode behavior. Nearly every clause carries information, though the mode/evidence sentence is somewhat compressed and would benefit from a clause on what it returns.

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?

This is a complex tool: 8 parameters, three enums, nested oneOf/object types, and no output schema. The description covers only the url/metadata alternative and one mode, leaving the majority of the input surface and the nature of the check's result unexplained. An agent would not know how to populate target, protocol, or data_classification from the description alone.

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 only 13%: of 8 parameters, only 'url' is documented, and the description merely restates it ('GAIP fetches, validates and reach-tests it'). The critical parameters 'target', 'protocol', 'intended_task', 'declared_identity' and 'data_classification' are unexplained in both schema and description, so the description fails to compensate for the coverage gap.

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+resource: checking an agent's declared interface (A2A, MCP, OpenAPI) before installation. The scope is legible even though 'declared interface' and 'GAIP' are jargon. There are no siblings to distinguish it from, so it cannot reach 5 on differentiation.

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?

Gives an explicit trigger ('use this when installing an A2A, MCP or OpenAPI agent') and a mode-specific condition ('Set mode VERIFY_BEFORE_CALL to inspect task-specific counterparty evidence before delegation'). It does not state when NOT to use the tool, so it stops short of a 5.

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