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

No annotations are provided, so the description carries the full burden, and it does substantial work: it discloses what the returned card contains and that the response includes a ready-to-share link plus machine-readable JSON endpoints. It omits auth/permission requirements and failure behavior, so it is strong but not exhaustive.

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 sentences, front-loaded with the primary purpose and return value. Dense with useful detail and little waste, though the middle sentence is a long clause chain that could be tightened.

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 no output schema, the description compensates by describing the return payload (shareable link plus JSON endpoints) and the card's contents. No annotations exist to cover safety behavior, but for a read-style getter with fully documented params, the remaining gaps are minor.

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 coverage is 100% and both optional params carry enum descriptions, so the schema already documents lang and niveau. The only added meaning is clarifying that 'standard' is the publicly exposed disclosure level; the rest restates the schema, matching the baseline of 3.

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?

Specific verb and resource: 'Get the public URL of an agent's Tracea KYA verification card,' and it enumerates what the card presents (mandant entity, permission scope, financial cap, proof hash). The purpose is unambiguous, but it never names or contrasts with near-siblings like verify_agent or get_agent_info.

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 a clear intended use — 'Use it to hand a verifier a link' — which tells the agent the context in which this is the right tool. It offers no exclusions or alternatives (e.g. when to prefer verify_agent instead), so it stops short of full routing guidance.

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