IntoDNS.ai service health

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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, so the safety profile is covered. The description adds valuable context beyond annotations: it notes internal Redis/AI-provider/process details are redacted on the public endpoint and that it is a 'single unauthenticated GET.' It doesn't describe the exact status values or response shape, but that's minor.

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 with the core identity in the first clause. Every sentence adds distinct value: scope, return values, redaction, usage, alternative, and transport/auth details. No filler or repetition.

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?

No output schema exists, but the description explains what is returned (overall service status and observation timestamp) and what is intentionally redacted. With no parameters and clear usage guidance, the description is fully adequate for an agent to call this tool correctly.

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 takes zero parameters, so the baseline is 4. There are no parameters to describe, and the schema coverage is 100% by default. No additional parameter semantics are needed.

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?

States a specific verb and resource: 'Read-only public health probe for the IntoDNS.ai backend itself, not a target domain.' Clearly distinguishes from all DNS-domain tools in the sibling list and names what it returns (overall status and timestamp).

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?

Explicitly says when to use: 'pre-flight check before batch jobs' and 'distinguish a service incident from a real DNS finding.' It also names an alternative for a related need: 'use get_stats for public usage counters instead.' No ambiguity.

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