check_many

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

With no annotations, the description reveals that checks are 'live' and returns 'concise verdict per target'. It does not disclose authorization needs, rate limits, or whether it is read-only (but reasonable to infer for a check). Could be more thorough but adequate.

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?

Two sentences, no filler, front-loaded with the core action ('run the live IP/domain reputation check'). Every sentence adds value.

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?

The description explains the return format ('one concise verdict per target') but lacks details on verdict structure, error handling, or behavior with invalid targets. Without an output schema, more could be said, but it covers the essential outcome.

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% for the single parameter 'targets', which already documents its type and meaning. The description adds example usage ('from your logs') but no additional syntax or constraints, so it meets baseline 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?

The description clearly states the tool runs live reputation checks on multiple IPs/domains at once and returns a verdict per target. It distinguishes from the sibling check_ip by explicitly indicating batch operation.

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 description provides usage context ('batch-vetting traffic', 'blocklist candidate set') and implies when to use this over check_ip (for multiple targets). However, it does not explicitly state when not to use it or mention alternative tools.

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