dnssec_algorithm_audit

Audit DNSSEC algorithms in DS, DNSKEY, and RRSIG records; map algorithm numbers to names, flag deprecated ones, and recommend ECDSAP256SHA256 or ED25519.

Instructions

Inventory all DNSSEC algorithms used in DS, DNSKEY, and RRSIG records. Maps algorithm numbers to names. Flags deprecated algorithms (RSA/MD5, DSA, RSASHA1) and recommends ECDSAP256SHA256 or ED25519.

Behavior3/5

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

With no annotations, the description carries the full burden of behavioral disclosure. It explains the analysis performed (inventory, mapping, flagging, recommending) but does not disclose side effects, network access requirements, read-only nature, or what happens if no relevant records exist. It adds value but lacks comprehensive transparency.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is concise and front-loaded with the primary action ('Inventory all DNSSEC algorithms'). It uses three short sentences that each add distinct value (scope, mapping, recommendations) with no wasted words or repetition.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a focused audit tool with no output schema, the description is fairly complete: it explains the scope (record types), the mapping behavior, and the output's key elements (deprecated flags, recommendations). It could improve by hinting at the output format or what to expect when no DNSSEC records exist, but overall it provides sufficient context.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema has 100% coverage for the single 'domain' parameter, so the baseline is 3. The description does not add any additional meaning about the parameter beyond what the schema already provides, but it does not need to since the schema is sufficient.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool's purpose: to inventory DNSSEC algorithms across DS, DNSKEY, and RRSIG records. It specifies actions (inventory, map, flag, recommend) and details deprecated and recommended algorithms, making it distinct from sibling DNSSEC tools like dnssec_validate or dnssec_check_ds.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies use for security audits by flagging deprecated algorithms and recommending modern ones, but it does not explicitly state when to use this tool versus other dnssec_* siblings. No exclusions or alternatives are provided, so usage context is implied rather than explicit.

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