email-quality-auditor is a skill in aaron-he-zhu/aaron-marketing-skills, last changed 28 Oct 2026. It can run shell commands, reach the network, name web addresses and pre-approve tools — read the findings before installing.

From the author

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

Install

Each tab says whether it installs commit a59327c, the one we checked, or the latest version.

OpenCode also looks in .agents/skills/ and ~/.agents/skills/, so use the Any agent steps.

Goose also looks in .agents/skills/ and ~/.agents/skills/, so use the Any agent steps.

Windsurf (Devin Desktop) also looks in .agents/skills/ and ~/.agents/skills/, so use the Any agent steps.

Zed also looks in .agents/skills/ and ~/.agents/skills/, so use the Any agent steps.

Roo Code also looks in .agents/skills/ and ~/.agents/skills/, so use the Any agent steps.

Factory Droid also looks in .agents/skills/ and ~/.agents/skills/, so use the Any agent steps.

Junie also looks in .agents/skills/ and ~/.agents/skills/, so use the Any agent steps.

Amp also looks in .agents/skills/ and ~/.agents/skills/, so use the Any agent steps.

No install command here reaches Kiro. Copy the skill's folder into .kiro/skills/ in your project, or ~/.kiro/skills/ for all your projects. aaron-he-zhu/aaron-marketing-skills/email/deliver/email-quality-auditor (opens in a new tab)

Antigravity also looks in .agents/skills/, so the Any agent steps reach it with This project. For All projects, see where Antigravity looks.

Cline also looks in .claude/skills/, so the Claude Code steps reach it with This project. For All projects, see where Cline looks.

No tab for your agent? Use Any agent for OpenCode, Goose, Windsurf (Devin Desktop), Zed, Roo Code, Factory Droid, Junie and Amp. With This project, Any agent also reaches Antigravity and Claude Code reaches Cline. Kiro needs the folder copied by hand.

What it can touch

From the files and frontmatter at commit a59327c. This is how much a skill can do, not whether it is risky.

Runs shell commands
Its instructions or files give the agent commands to run on your computer.
Reaches the network
It sends or fetches data over the internet, for example with curl, an HTTP library or a package install.
Names web addresses
It mentions outside web addresses the agent may visit. We list them but don't follow them.
Outside links we did not follow
Pre-approves tools
Its allowed-tools field lists tools the agent may use without asking you first, in agents that honour it.

We checked every text file in this skill, at commit a59327c on 3 Nov 2026, against 45 published patterns such as download-and-run commands, hidden text and credential access. We don't run the skill, we don't read the web pages it points to, and we can't judge everything its instructions might lead an agent to do. In published tests, pattern checks like this one missed most malicious skills. Read the skill before you install it — especially anything it asks you to download or run.

Format check

Each agent reads SKILL.md a little differently. We check the file against each one's published rules; we don't run the skill in any agent.

Agent Skills specPasses with warnings
The open format from agentskills.io, held to the strictest version of each rule among the agents we check.
- Warning
  The frontmatter uses [ ] or { } values. Most agents accept them, but the spec's validator (skills-ref) rejects the file. F4
  Fix: Write lists as "- item" lines and maps as indented key: value lines, without anchors or tags.
- Warning
  Fields outside the spec: slug, displayName, summary, version, homepage, when_to_use (read by Claude Code), argument-hint (read by Claude Code and VS Code) and class. Uploads to the Claude apps and API, and the spec's validator, reject the file; most agents ignore these fields. O1
  Fix: Delete them for a portable skill, or keep them if you only target the agents that read them.
- Warning
  metadata values should be text; hermes (a map) and openclaw (a map) are not. The spec's validator turns them into text; other readers may not. O4
  Fix: Quote each value, for example version: "1.0".
- Warning
  Paths that may not work once the skill is installed: line 136: ../../../references/send-benchmark.md (outside the skill folder), line 137: ../../../references/measurement-protocol.md (outside the skill folder), line 138: ../../../references/auditor-runbook.md (outside the skill folder), line 139: ../../../references/scoring-semantics.md (outside the skill folder), line 143: ../../setup/deliverability-qa/SKILL.md (outside the skill folder) and 3 more. B6
  Fix: Use forward-slash paths relative to SKILL.md, and copy shared files into the skill.
- Note
  Reference files over 100 lines with no table of contents at the top: references/auditor-runtime.md (437 lines). B5
  Fix: Add a short list of the sections at the top of each.
Claude CodePasses with warnings
Claude Code reads its own extra fields, ignores unknown ones, and still loads a skill whose frontmatter is broken, without its fields.
- Warning
  Paths that may not work once the skill is installed: line 136: ../../../references/send-benchmark.md (outside the skill folder), line 137: ../../../references/measurement-protocol.md (outside the skill folder), line 138: ../../../references/auditor-runbook.md (outside the skill folder), line 139: ../../../references/scoring-semantics.md (outside the skill folder), line 143: ../../setup/deliverability-qa/SKILL.md (outside the skill folder) and 3 more. B6
  Fix: Use forward-slash paths relative to SKILL.md, and copy shared files into the skill.
- Note
  Claude Code ignores fields it doesn't know: slug, displayName, summary, version, homepage and class. O1
  Fix: Check the spelling against Claude Code's field list, or delete them.
- Note
  Reference files over 100 lines with no table of contents at the top: references/auditor-runtime.md (437 lines). B5
  Fix: Add a short list of the sections at the top of each.
Claude apps & API uploadFails
Uploading to claude.ai or the Claude API, or packaging with Anthropic's script, accepts only the six spec fields and stops on anything else.
- Error
  Upload and packaging fail on fields outside the spec: slug, displayName, summary, version, homepage, when_to_use, argument-hint and class. O1
  Fix: Delete them, and keep your own data under metadata as text values.
- Warning
  Paths that may not work once the skill is installed: line 136: ../../../references/send-benchmark.md (outside the skill folder), line 137: ../../../references/measurement-protocol.md (outside the skill folder), line 138: ../../../references/auditor-runbook.md (outside the skill folder), line 139: ../../../references/scoring-semantics.md (outside the skill folder), line 143: ../../setup/deliverability-qa/SKILL.md (outside the skill folder) and 3 more. B6
  Fix: Use forward-slash paths relative to SKILL.md, and copy shared files into the skill.
- Note
  The description is 345 characters. The claude.ai Help Center says 200 at most, though Anthropic's API docs and validator allow 1,024. D4
  Fix: If the claude.ai upload refuses it, trim the description to 200 characters.
- Note
  metadata values should be text; hermes (a map) and openclaw (a map) are not. The spec defines metadata as text to text. O4
  Fix: Quote each value, for example version: "1.0".
- Note
  Reference files over 100 lines with no table of contents at the top: references/auditor-runtime.md (437 lines). B5
  Fix: Add a short list of the sections at the top of each.
OpenAI (Codex & API)Passes with warnings
Codex finds SKILL.md by its exact name and needs a description; OpenAI's Skills API checks the frontmatter against the spec and caps uploads.
- Warning
  Fields outside the spec: slug, displayName, summary, version, homepage, when_to_use, argument-hint and class. Codex ignores them; OpenAI doesn't say whether its upload accepts them. O1
  Fix: Delete them, or move your own data under metadata as text values.
- Warning
  metadata values should be text; hermes (a map) and openclaw (a map) are not. OpenAI's upload follows the spec's text-to-text rule. O4
  Fix: Quote each value, for example version: "1.0".
- Warning
  Paths that may not work once the skill is installed: line 136: ../../../references/send-benchmark.md (outside the skill folder), line 137: ../../../references/measurement-protocol.md (outside the skill folder), line 138: ../../../references/auditor-runbook.md (outside the skill folder), line 139: ../../../references/scoring-semantics.md (outside the skill folder), line 143: ../../setup/deliverability-qa/SKILL.md (outside the skill folder) and 3 more. B6
  Fix: Use forward-slash paths relative to SKILL.md, and copy shared files into the skill.
VS Code & CopilotPasses with warnings
VS Code reads skills one folder below .github/skills, .claude/skills or .agents/skills and falls back to the folder name when the name is missing or differs; GitHub's Copilot docs require the exact name SKILL.md.
- Warning
  Paths that may not work once the skill is installed: line 136: ../../../references/send-benchmark.md (outside the skill folder), line 137: ../../../references/measurement-protocol.md (outside the skill folder), line 138: ../../../references/auditor-runbook.md (outside the skill folder), line 139: ../../../references/scoring-semantics.md (outside the skill folder), line 143: ../../setup/deliverability-qa/SKILL.md (outside the skill folder) and 3 more. B6
  Fix: Use forward-slash paths relative to SKILL.md, and copy shared files into the skill.
- Note
  VS Code ignores fields it doesn't support: slug, displayName, summary, version, homepage, when_to_use and class. O1
  Fix: Delete them unless another agent you target reads them.

Not for the point-in-time R2 veto or RQS gate — use ad-account-auditor; not for the ROI/ROAS ratio math itself — use roi-calculator; not for organic dark-social share attribution or GA4 direct-traffic decomposition — use dark-social-attributor. 付费广告归因对账/去重/增量 Names web addresses Pattern check: Nothing flaggedApache 2.0Updated 28 Oct 2026	Names web addresses	Pattern check: Nothing flagged	Apache 2.0	28 Oct 2026
