peerglass_dns_dnssec

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

Annotations cover the safety profile (readOnly/idempotent), but the description adds valuable behavioral context not in structured data: the four possible return statuses (SECURE/INSECURE/BOGUS/INDETERMINATE), the specific meaning of BOGUS (signatures exist but fail validation), and the security implications. No contradictions with annotations.

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?

Well-structured with clear sections: purpose statement, BOGUS status explanation, Args, and Returns. The Args/Returns sections slightly duplicate schema information but provide necessary context given the 0% top-level coverage. The BOGUS explanation sentence earns its place by highlighting security relevance.

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 complexity (cryptographic validation), the description adequately covers inputs, outputs, and behavioral traits. It documents return value meanings and signing algorithms. Minor gap: it assumes network access (openWorldHint is true in annotations) but doesn't describe network dependency or potential timeouts in the text.

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?

With 0% top-level schema description coverage (the 'params' object lacks a description), the description compensates via the Args section detailing the nested DNSSECInput structure, including the domain example ('cloudflare.com') and response_format options ('markdown' or 'json'). This adds necessary semantic meaning beyond the bare schema.

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 specific action ('Validate the DNSSEC chain-of-trust') and resource (DNSSEC records for a domain), distinguishing it from generic DNS resolution siblings like peerglass_dns_resolve by explicitly mentioning DNSKEY, DS, and RRSIG record types.

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?

While the description clearly explains what BOGUS status means (misconfiguration/tampering indicator), it lacks explicit guidance on when to use this versus sibling tools like peerglass_dns_resolve or peerglass_dns_censorship. The usage is implied by technical specificity but not explicitly stated.

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