What it does

Email Quality Auditor is an agent skill from aaron-he-zhu/aaron-marketing-skills. Use when the user asks to "audit an email program" or "is this campaign safe to send"; runs a typed 20-item SEND profile with authentication, consent, opt-out, and claim veto checks on own evidence. Not for building deliverability setup — use deliverability-qa; not for designing lifecycle flows — use email-sequence-designer. 邮件质量审计/EQS评分/发送前放行

Its SKILL.md is about 2.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/auditor-runtime.md`). Compatibility notes: Claude Code and compatible agent-skill hosts

It sits in Marketing & SEO, covering Transactional email and Email marketing. The repository describes itself as: 120 marketing skills as an AI marketing staff — plugin, portable skills, or an 8-bot team across 7 disciplines (narrative, SEO/GEO, social, email, paid, influencer, launch) on… The licence is Apache-2.0.

When your agent uses it

  • The user asks to audit an email program
  • Is this campaign safe to send
  • Runs a typed 20-item SEND profile with authentication
  • Claim veto checks on own evidence

Example prompts

  • “audit an email program”
  • “is this campaign safe to send”
  • “/email-quality-auditor”

Requirements

  • Compatibility (from SKILL.md): Claude Code and compatible agent-skill hosts
  • Pre-approved tools (allowed-tools): WebFetch

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. Freeze evidence and reconcile provider cohorts/windows before comparing rates.
  2. Score all 20 S1..D5 criteria. Every observed state requires source/date/type/confidence.
  3. E2 is N/A with reason when opens/CTOR are not used. N3/N5 are conditional by program design. Missing records or exports are Unknown, not…
  4. Verify vetoes
  5. Run the typed scorer. Use clicks/replies/downstream actions as primary engagement evidence where available; opens/CTOR remain caveated…

What it can do on your machine

Read from SKILL.md and the folder at commit 0ab9024. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • WebFetch

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • git

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

  • Compatibility

    Claude Code and compatible agent-skill hosts

    From compatibility in the SKILL.md frontmatter.

Context cost

Email Quality Auditor loads about 2.1k tokens when it runs, and up to ~5.8k if it reads all its reference files. Until then it costs about 92 tokens; SKILL.md has 721 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~92
When it runs · the whole SKILL.md, loaded when a task matches
~2.1k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~5.8k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Email Quality Auditor

Audit one email program/profile and observation window with SEND. Open rate is MPP-sensitive proxy evidence; direct action and the program's declared outcome truth set carry the outcome read.

When This Must Trigger

  • Before a material broadcast/sequence release when channel safety is uncertain.
  • When authentication, consent, suppression, complaints, frequency, claims, or attribution need a gate.
  • When the user requests an EQS/SEND baseline or rerun.

Quick Start

text
Audit this newsletter using the last 90 days, provider split, MPP share, and subscription truth set.
Check this promotional send against DMARC, consent events, live suppressions, claims, and order IDs.

Skill Contract

Reads: one program/profile, normalized window, provider evidence, live consent/suppression state, rendered messages, and outcome truth. Writes: only a permissioned v3 artifact. Done when: all expected SEND states are explicit and the scorer result is reported without sending email or changing provider settings.

Use deliverability-qa to repair authentication, consent-registry for lawful-basis/suppression facts, email-sequence-designer for journeys, and send-experiment-designer for preregistered tests.

Data Sources

NeedPreferred evidence
AuthenticationDNS, message headers, DMARC aggregate evidence
Consent/suppressionAppend-only consent events plus current live projection
Placement/reputationProvider/seed panel and dated ESP/provider reports
EngagementCohort/provider/MPP-segmented ESP export
LifecycleTrigger/flow configuration and event export
OutcomeEcommerce, CRM, subscription, sponsorship, or named equivalent truth set
ContentRendered message/destination and approved claim/disclosure state

Instructions

Runtime Reads
  • ../../../references/auditor-runbook.md
  • ../../../references/scoring-semantics.md
  • ../../../references/send-benchmark.md
  • ../../../references/runtime-invocation.md
  • references/auditor-runtime.md
Runtime and Setup

Read ../../../references/auditor-runbook.md, scoring-semantics.md, send-benchmark.md, and the SEND catalog entry. Standalone installs use bundled immutable references/auditor-runtime.md; never fetch mutable main. Before deterministic calls, follow runtime-invocation.md, resolve AARON_SKILLS_ROOT="${CLAUDE_PLUGIN_ROOT:-$(git rev-parse --show-toplevel 2>/dev/null || true)}", and require the scorer, validator, and typed catalogs. If unavailable, return score_state: NOT_SCORED / score_confidence: not_scored with no gate verdict or persistent artifact.

Declare profile (promotional|retention|cold-outbound|newsletter), target/program, provider, market, normalized window, list age, MPP share, and observation date.

Evidence and Scoring
  1. Freeze evidence and reconcile provider cohorts/windows before comparing rates.
  2. Score all 20 S1..D5 criteria. Every observed state requires source/date/type/confidence.
  3. E2 is N/A with reason when opens/CTOR are not used. N3/N5 are conditional by program design. Missing records or exports are Unknown, not N/A.
  4. Verify vetoes:
    • SEND-S1: required authentication is demonstrably broken/unaligned.
    • SEND-S2: a purchased/scraped/unlawful list is verified; missing provenance is Unknown.
    • SEND-N1: opt-out is broken/absent or a recorded suppression is not honored.
    • SEND-D1: material claim/disclosure/offer term fails approved evidence.
  5. Run the typed scorer. Use clicks/replies/downstream actions as primary engagement evidence where available; opens/CTOR remain caveated proxy evidence.

For a send-only review without enough program evidence, report the verified red-line checks and exact gaps but return NOT_SCORED/UNDECIDED; “no blocker observed in supplied evidence” is not a full SEND SHIP verdict.

§2 SEND Worked Examples

  • Complete newsletter profile, raw 81, no veto/fail: DONE/SHIP, final 81.
  • Complete promotional profile, raw 76, one verified S1 failure: DONE_WITH_CONCERNS/FIX, final 59.
  • Complete profile, verified S2 and N1 failures: DONE/BLOCK, no final score.
  • Consent provenance absent: S2 Unknown, NEEDS_INPUT/UNDECIDED, no score.
Show full SKILL.md (278 more words)Show less

§3 SEND Guardrails

  • DMARC p=none with aligned SPF/DKIM and active monitoring is not automatically an S1 failure.
  • Provider one-click-unsubscribe policy and statutory duties must be named separately.
  • Opens and CTOR require MPP segmentation/proxy caveat; they cannot establish human attention alone.
  • A newsletter need not have cart/post-purchase flows; score only journeys applicable to its declared program.
  • Over-frequency is a serious E4/E5 finding, not an automatic veto.

§5 SEND Translation

Explain channel and recipient risk in plain language. On trace request, qualify SEND-S1/S2/N1/D1 and show the underlying DNS/event/rendered evidence.

Report and Verdict

Begin with the auditor-runbook's exact typed conversation header. Never replace status, verdict, or score_state with prose; list each explicitly missing qualified item as ``ID: `unknown``` before findings.

Show verdict, profile/context, score or coverage/interval, confidence, S/E/N/D detail, outcome truth set, verified critical controls, Unknown inputs, and fix owners. Do not claim deliverability/inbox placement from DNS alone and do not execute a send.

Validation Checkpoints

  • Program/profile/provider/window/list age/market/MPP share are declared.
  • Live suppression state was verified by replay, not a stale projection or pending proposal.
  • All 20 states are valid; conditional N/A has a reason.
  • Provider metrics and reconciled outcome truth are separated.
  • No email/provider mutation occurred without separate explicit approval.

Persistence

Persist only after explicit authorization to memory/audits/email/YYYY-MM-DD-<topic>.md. Preserve the scorer's orthogonal status and verdict; validate the complete v3 draft with validate-audit-artifact.py against the intended --relative-path, persist only through one full-content Write, and revalidate the target per the auditor runbook. Edit/shell/MCP mutations of the reserved sink are unsupported. Do not autonomously modify consent, claims, provider settings, or hot cache.
