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

With no annotations, the description carries the full behavioral burden. It usefully signals a read-only scanning operation with deterministic output and remediation artifacts, but says nothing about authentication, rate limits, runtime/duration, or whether the target domain is contacted. These operational traits matter for a network scanner.

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?

It is a single sentence with the action and result front-loaded and little waste. The leading clause ('6-Agent SaaS Contract, GDPR Art. 28 DPA & EU AI Act Auditor') is dense keyword framing rather than functional detail, which slightly dilutes front-loading.

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 one-param tool with a fully documented schema and no output schema, the description does credibly summarize what comes back (scores and artifacts). However, it leaves the return format, how to consume remediation artifacts, and operating constraints (auth, duration) unstated, so it is adequate but not complete.

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?

There is a single parameter at 100% schema coverage, so the baseline is 3. The description adds one meaningful constraint beyond the schema ('public HTTPS'), which is helpful, but does not clarify domain format or edge cases beyond the schema's stripe.com example.

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 names a specific action (audits/scans) and resource (public HTTPS domains) and states the return (readiness scores, remediation artifacts). An agent can tell what the tool does, though it never contrasts itself with siblings (which appear unrelated). The marketing-style framing adds noise but the verb+resource is clear.

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?

Usage is only implied by the phrase 'scans any public HTTPS domain,' which hints at the eligible input class but gives no explicit when/when-not guidance and names no alternative. Siblings look unrelated, so the omission is less damaging, but no prerequisites or exclusions are stated.

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