apihealth_check_many

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

With no annotations, the description carries the full burden of behavioral disclosure, but it only says 'Check multiple URLs.' It does not disclose network behavior, side effects, timeouts, error handling, output format, or whether any state is changed.

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 extremely brief, but this is under-specification rather than effective conciseness. The description provides almost no useful structure or context beyond what can be inferred from the tool name itself.

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?

There is no output schema and no annotations, yet the description does not explain what 'check' returns, how success/failure is represented, or any limitations. An agent could construct a request but would not be able to interpret or validate the result.

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 parameter is already fully described in the schema as 'Newline-separated URLs,' so the description adds no extra semantic meaning. Baseline 3 applies because schema description coverage is 100%.

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 uses a clear verb-resource pair ('Check multiple URLs') and the plural 'multiple' distinguishes it from sibling apihealth_check. However, 'check' is generic and does not explain what kind of check (health, status, reachability) is performed or how it relates to apihealth_status.

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 about when to use this tool versus apihealth_check or apihealth_status. The plural wording implies batch usage, but that is left to inference rather than explicitly stated.

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