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

With no annotations, the description carries full burden for behavioral disclosure. It provides none: no mention of read-only nature, side effects, authentication needs, or rate limits. The agent cannot assess safety or impact.

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 extremely short (4 words), but this is under-specification rather than conciseness. It fails to convey necessary information beyond the tool's name.

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?

Given 3 parameters, no annotations, and no output schema, the description is severely incomplete. The agent cannot understand the return format, parameter ecosystem, or usage scenarios. A responsible description would elaborate on the response and parameter behavior.

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 description adds no meaning beyond the input schema. The schema has 67% coverage, but the name parameter lacks a description, and the 'fields' and 'include' parameters are not elaborated. No parameter examples or constraints are provided.

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 'Get domain by name' clearly states the action and resource, but lacks differentiation from sibling tools like 'get-domain' and 'get-domain-summary'. It implies lookup by name but doesn't specify how it differs from possibly by-ID retrieval.

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?

No guidance is provided on when to use this tool versus alternatives (e.g., 'get-domain', 'get-domain-summary'). The agent cannot determine the appropriate context for selection.

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