nhcx_validate_config

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

With no annotations provided, the description carries the full transparency burden. It clearly states the actions performed (validating environment variables and testing API connectivity) without implying any hidden side effects. The behavior is unambiguous, though it does not explicitly state whether the operation is read-only or what happens on failure.

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 two sentences, front-loaded with the tool's action. It contains no redundant information and efficiently conveys both purpose and usage timing.

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 the tool's simplicity (no parameters, no output schema, no annotations), the description adequately covers its purpose and usage. However, it does not specify what output or exit status the user should expect after validation, which would enhance completeness but is not critical for a straightforward validation tool.

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 tool has zero parameters, and per the guidelines, no parameter description is needed. The description's mention of 'environment variables' and 'API connectivity' indirectly clarifies what is being validated, but since there are no parameters, a baseline of 4 is appropriate.

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's function with specific verbs and resources: 'Validate all environment variables and test connectivity to NHCX APIs.' This distinctly separates it from sibling tools like nhcx_login and nhcx_process_case, and 'Run this first' signals its role as a precursor step.

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 explicit usage timing with 'Run this first to confirm your setup is correct.' This gives clear context for when to use the tool, though it does not mention specific alternatives or exclusion cases, which are less necessary given its distinct validation role.

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