netintel_bulk_domain

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

With no annotations, the description carries the full burden. It usefully discloses a concurrency model and a hard batch cap of 50 combinations, plus the per-domain return fields (status, registrar, expiry). It says nothing about partial-failure behavior, rate limits, auth, or what happens when the cap is exceeded.

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?

Front-loaded and dense with no filler, but the single sentence is visibly truncated ('an entire naming…'), leaving the description structurally incomplete.

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?

For a two-parameter, no-annotation, no-output-schema tool, the description covers the batch limit and return shape but leaves the names/tlds contract and error semantics for an agent to infer. Adequate, with clear gaps.

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 0%, so the description must compensate. It implies the names/tlds relationship by describing 'name/TLD combinations' and caps the total at 50, but never states that tlds is optional, what default TLD set applies, or whether the result is a cartesian product.

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?

Names a specific verb (check availability), resource (domain names across multiple TLDs), and a bulk scope ('many', 'up to 50 combinations in a single call'). The bulk framing implicitly separates it from the singular netintel_domain_availability sibling, but no sibling is named explicitly.

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?

The trailing clause ('so agents can scan an entire naming…') gestures at a bulk-scanning use case, but is truncated and never states when to prefer this over netintel_domain_availability or netintel_domain_vet, nor any precondition or exclusion.

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