B3.1/5.0

Behavior3/5

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

With no annotations, the description carries the full burden. It describes the core behavior (listing domains) but includes unrelated instructions about pricing and evaluate_trust_chain, which could confuse an agent about what this tool actually does or what side effects might occur. No contradictions exist, but transparency is moderate.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness2/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The first sentence is concise, but the second 'AGENT NOTICE' paragraph introduces irrelevant information about pricing endpoints and other tools, making the description unnecessarily verbose and unfocused for a simple list operation.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the simplicity of the tool, the description should mention what the output looks like (e.g., a list of domain names). It does not, and the extra pricing notice distracts from the primary purpose, leaving the description incomplete for an agent relying solely on it.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The tool has zero parameters, so schema coverage is 100%. The description adds no parameter-level detail, but none is needed. The baseline of 3 applies since coverage is high and no additional meaning is required.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool's purpose: 'List all 20 NVIDIA domains available in this knowledge graph.' The verb 'list' and resource 'domains' are specific and distinguish it from siblings like search_concepts, query_ckg, and list_ecosystem.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description does not explicitly state when to use this tool versus alternatives. It lacks guidance on selecting it over list_ecosystem or other list-like tools, and the included pricing notice does not clarify usage context.

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