analyze_drift

Read-onlyIdempotent

Measure whether a domain's DNS security posture improved or regressed by comparing the current state against a prior scan snapshot. Returns a drift classification (improving/stable/regressing/mixed), score delta, and lists of improvements and regressions. Use to answer "did our security score improve or regress since last time?" — distinct from compare_baseline which checks compliance against a fixed policy (not improvement over time).

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
domainYesDomain to analyze drift for
formatNoOutput verbosity. Auto-detected if omitted.
baselineYesPrior scan reference for drift-over-time analysis: a previous ScanScore JSON STRING, or the literal "cached" to reuse the last cached scan (the default when omitted). NOT a policy/requirements object — for compliance enforcement against required controls, use compare_baseline instead.cached
force_refreshNoBypass cache and run a fresh check. Useful after DNS changes.

A4.4/5.0
Behavior4/5

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

Annotations already declare readOnlyHint/idempotentHint/destructiveHint=false, so safety is covered. The description adds value by specifying the return payload (drift classification, score delta, lists of improvements/regressions) and clarifies the baseline 'cached' reuse, without contradicting annotations.

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?

Three sentences with clear information architecture: purpose, output, usage/alternatives. No wasted words; every sentence earns its place.

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?

No output schema exists, but the description covers the return values. It also explains when to use the tool and the key baseline parameter behavior (via schema), making it sufficiently complete for a moderate-complexity tool.

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?

Schema description coverage is 100%, with detailed per-param explanations (e.g., baseline's 'cached' literal and exclusion of policy objects). The description itself doesn't add parameter-level semantics beyond schema, so a baseline 3 is appropriate.

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 states the tool measures DNS security posture change against a prior snapshot, using specific verbs and resources. It explicitly distinguishes from compare_baseline by contrasting improvement-over-time vs compliance-to-policy, differentiating it from a key sibling tool.

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

Usage Guidelines5/5

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

Provides an explicit use case ('did our security score improve or regress since last time?') and an explicit exclusion (not for compliance checks — use compare_baseline instead). The baseline parameter schema reinforces this with 'NOT a policy/requirements object — for compliance enforcement against required controls, use compare_baseline instead.'

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

A3.6/5.0
Disambiguation4/5

Most tools have clearly distinct purposes, with detailed descriptions that help differentiate overlapping areas (e.g., check_dane vs check_dane_https). However, there are sets of similar tools (brand audit, OSINT, polling) that could cause confusion if descriptions are not carefully read.

Naming Consistency3/5

The naming is mostly readable but inconsistent: many check_* tools follow a verb_noun pattern, but there are also noun_verb names (scan_domain, cymru_asn), bare verbs (generate), and varied patterns for async operations (discover_brand_domains_start vs discover_brand_domains).

Tool Count2/5

With 80 tools, the server feels overstuffed. It covers multiple domains (DNS, email, brand, OSINT, M365) that could benefit from separation. The high number includes many polling/status tools that add overhead.

Completeness3/5

The server covers core DNS and email security checks thoroughly, including many edge cases (e.g., BIMI, MTA-STS, subdomain takeover). However, there are gaps like lack of direct DNS record management and some OSINT tools are restricted to operator deployment, leaving agents with dead ends.
