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

With no annotations provided, the description carries the full burden and discloses almost nothing. It implies a read of profile data but never states read-only behavior, what the profile contains, or whether agentId scopes the lookup to a specific agent context.

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 text is short and front-loaded, but half of it is a redundant Dutch translation of the same sentence, which adds length without adding information for an English-speaking agent.

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?

No annotations, no output schema, and an undocumented required parameter mean the description must carry the definition, yet it says nothing about the return shape or the agentId's role. It is not complete enough for an agent to invoke confidently beyond guessing.

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 single required parameter agentId has 0% schema description coverage, and the description offers no explanation of what an agentId is, where it comes from, or how it affects the result. With one undocumented parameter, the description needed to compensate and does not.

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 names the resource ('Merchant profile of Good Nature Vibe') but supplies no verb, leaving it ambiguous whether the tool retrieves, creates, or describes a profile. It also does nothing to distinguish it from siblings like gnv_contact or gnv_knowledge, which plausibly overlap with merchant information.

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?

There is no statement of when to call this tool versus alternatives such as gnv_contact or gnv_knowledge. The agent must infer that this fetches static merchant identity details, with no exclusions or prerequisites given.

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