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

Adds real behavioral detail beyond the annotations: the PASS rule (every criterion resolved and no new critical or high finding), the fact that nothing is stored, and the billing caveat that a pass is not an invoice while orders are closed. The 'nothing is stored' claim largely restates readOnlyHint and the closing clause is cryptic, but the pass/fail semantics are genuinely new information.

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 action and the pass condition, then trimmed with a short caveat sentence. It is dense but mostly earns its words; the final clause about invoices and closed orders is ambiguous and could be clearer or removed.

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, so the description carries the burden of explaining the return value, and it only covers the PASS case. It does not say what a FAIL response contains (which findings or unresolved criteria are reported) or how new findings are surfaced, which is the main thing an agent would need after calling it.

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 description coverage is 100%, and the schema already says token, baseline and criteria come from the quote. The description reinforces that the criteria and baseline derive from an earlier quoteFixVerify result, but adds no format, ordering, or partial-match semantics beyond what the schema provides.

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: re-runs the domain check and compares results against the acceptance criteria and baseline of an earlier quoteFixVerify result. The dependency on quoteFixVerify is named, which separates it from that sibling. It does not explicitly contrast with checkDomain, so an agent must infer that this is the post-fix re-check rather than a first-time scan.

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: you need an earlier quoteFixVerify result, and the title suggests it follows a DNS change. There is no explicit statement of when to call this instead of checkDomain or quoteFixVerify, and no stated preconditions for the token or baseline beyond 'from the quote' in the schema.

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