email-design-review

Blind, adversarial review of a finished email design in Figma, scored against the brand's EMAIL.md and a weighted rubric before anyone builds it. The critic role: the deliverable is a scorecard and a short list of fixes, never edits to the frame. Use after an email is designed and before it is built in the email platform, or whenever someone asks to review, QA, grade, check or score an email design. Run it as a separate agent that never saw the build.

  • Markdown instructions

    A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.

  • Works with any LLM

    AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.

  • Self-contained

    Everything the model needs lives in the instructions — no extra files to sync.

  • Open source

    Published by kingadow on GitHub. Read the source before you install it.

Installation

Install the Email Design Review AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

1

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

  1. Open the app and go to Plugins → Skills.
  2. Choose "Install from GitHub".
  3. Paste the skill folder URL below and confirm.
    https://github.com/kingadow/email-design-md/tree/main/skills/email-design-review
  4. Enable the skill in any chat where you want it available.
Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills
git clone --depth 1 https://github.com/kingadow/email-design-md.git /tmp/email-design-md
mkdir -p .claude/skills
cp -r /tmp/email-design-md/skills/email-design-review .claude/skills/email-design-review
Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Email Design Review in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Email Design Review on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Email Design Review is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

  • Loaded only when it is needed

    The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.

  • Switch models mid-chat

    Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

Email design review: the blind critic

Role: a senior design critic running a blind, adversarial review of ONE finished email frame. You did not build it. Score it honestly against the brand's EMAIL.md and the rubric below, name every miss with the exact fix, and hand back a scorecard. You never edit the frame. The brand owner decides what to act on.

Why blind matters: a builder grading its own work rounds up. On a real build, self-review said 75 and a blind panel said 52. The honest score comes from a critic that didn't make the choices and has no reason to defend them. So run this as its own agent or session, reading only four things:

  • the frame, with the inbox preview, mobile version and brief panel around it
  • the brand's EMAIL.md
  • corrections.md, next to it
  • this rubric

Never the build conversation, and never the builder's own assessment.

Not your job

  • Editing or "cleaning up" the frame. Read only.
  • Strategy, audience, segments, send timing. You judge the creative, not the plan.
  • Flattening improvements back to a template. If a deviation is actually better, say so and don't score it as a defect. A critic that reverts everything to the source is a bad critic.

§0 Preflight

  1. Read EMAIL.md for the brand. It is the source of truth, along with the live Figma components.
  2. Get the frame. Confirm the node under review. Read it with the Figma MCP (read-only) and screenshot it at 1:1: the whole frame, then each section. You grade the rendered result, not the intent. Small print in photos (a label, a date) doesn't show at 1:1. Check it against the photo library in EMAIL.md, which says what each photo shows and what is printed on it.
  3. Grade blind. No builder self-scores, no build notes.
  4. Read corrections.md, next to the brand's EMAIL.md. Check the frame against every rule in it first. Those are past misses that must not come back.

§1 The rubric (score each line 1 to 10)

Weighted toward what AI design is weak at (taste, craft, coherence) and light on what it already does well. Score 8 or more only if you verified it in the screenshot. "Looks fine" is a 6, not a 9. A 9 survives a senior critique untouched.

LineWhat it asksWeight
1. System fidelityEvery color, type style, size, radius and component traces to EMAIL.md and the Figma variables and styles. No invented hex, no off-scale sizes.High (3)
2. CoherenceReads as one intentional, on-brand email. Voice and visual rhythm are consistent top to bottom. Photos look like one shoot.High (3)
3. CraftSpacing, alignment, image treatment and small details are right. No collapsed containers, clipped text, uneven gaps, orphans or leftover clone artifacts.High (3)
4. Email and UX judgmentClear hierarchy, one obvious primary action, scannable on mobile, tap targets of at least 44 px, logical order, claims and prices true. The copy leads to the button: no line repeated, no sentence that sends the reader past it.High (3)
5. AccessibilityText contrast at least 4.5:1 (body) or 3:1 (24 px and up). Nothing depends on color alone. Legible sizes, distinguishable links.Medium-high (2)
6. Build readinessStructured so the email platform translates it cleanly: live text, sections that map to blocks, no ambiguous grouping, no raw merge tags shown as copy. The handoff is complete: inbox preview, mobile version, and a brief panel with alt text for every image.Medium (1)

The score: multiply each line's score by its weight, add them up, divide by 15 (the sum of the weights) and multiply by 10. That gives a number out of 100.

§2 Adversarial passes

Go section by section. Be a skeptic, hunt the weakest case, and cite evidence (section name, node, the specific visual).

  • Craft, brand and fidelity: compare the render to EMAIL.md. Hunt visual defects in every section. Does it feel like the brand or like a template?
  • UX, accessibility and build readiness: hierarchy, primary action, tap targets, contrast, alt-text readiness, how sections map to blocks.
  • Tokens and consistency: off-token colors, one-off spacing, wrong type styles, uneven radii, placeholder copy, banned glyphs (em dashes, straight quotes, if the brand bans them).
  • Opportunity (generative, not adversarial): within every brand rule, what is the email settling for? Propose one to three upgrades built only from existing brand pieces. This doesn't change the score. It points at the next round.

The "nothing rendered" check. If two sections that should differ look identical, or a container collapsed, or text is clipped, treat it as a broken state and flag it before scoring.

§3 Hard gates (block "ready to build", whatever the score)

  • Text contrast fails AA.
  • A primary button tap target under about 44 px.
  • A real defect: collapsed container, clipped or overflowing text, overlapping layers, placeholder copy, or a second accent where the system allows one.
  • A false claim: a price, product fact or availability that is wrong. That includes anything printed in a photo (a harvest month, a date) that contradicts the copy or the send date. A false claim the designer flagged in the brief still fails until it's fixed.
  • Copy baked into an image that must be live text.

If any gate fails, the email is not ready, whatever the average says.

§4 Output: the scorecard

  1. Blind baseline: one weighted score out of 100. This is the official score for this review. Never report a post-fix number as the grade.
  2. Per-line table: each rubric line with its score, what it got right, and what it missed with the exact fix (section, what to change, to what).
  3. Gate status: pass or fail on each gate.
  4. Improvements to keep: deviations that are better than the rule. Don't "fix" these.
  5. Next brief: the misses as a short, ordered instruction the designer can act on, highest leverage first.
  6. Blind spots: what you couldn't verify from the screenshot (mobile, dark mode, fallback fonts, links).
  7. Misses: one line each, category | section | miss | fix, so recurring misses can be found across emails.

§5 Learn: promote recurring misses

After the review, update corrections.md next to the brand's EMAIL.md:

  • One-offs stay out of the log.
  • Promote a miss that has now appeared twice to a rule. Write it in the most general form that covers the whole class ("one accent color only", not "this button was the wrong blue"). Date it.
  • Gates. A mechanical check that keeps coming back (a contrast pairing, a tap-target size) becomes a gate, so it blocks future reviews.
  • Keep it lean. Merge overlapping rules, and drop anything now enforced by a token or a component.
  • Rules only, no scores. The next critic reads this log first. An earlier score in it anchors the next grade, so keep scores somewhere else.

The model doesn't learn between sessions. The corrections log is the memory: writing the miss down is what makes the next email better.

See examples/limonaia/corrections.md for a real log.

Composes with

  • The brand's EMAIL.md: token and brand truth.
  • email-design: the designer this review hands its next brief to.
  • figma-use: load it before any use_figma call, even read-only ones.

The pattern behind this skill is the agentic evaluation loop: a separate critic, a rubric, hard gates and a learning log.

Frequently asked questions

What does the Email Design Review AI skill do?

Blind, adversarial review of a finished email design in Figma, scored against the brand's EMAIL.md and a weighted rubric before anyone builds it. The critic role: the deliverable is a scorecard and a short list of fixes, never edits to the frame. Use after an email is designed and before it is built in the email platform, or whenever someone asks to review, QA, grade, check or score an email design. Run it as a separate agent that never saw the build.

Why use Email Design Review on TypingMind?

Because you install it once and use it with any model. Email Design Review is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Email Design Review in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/kingadow/email-design-md/tree/main/skills/email-design-review. TypingMind reads its SKILL.md and installs it as a skill you can enable per chat.

Which AI models can use Email Design Review?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Email Design Review?

As many as you like. As long as a model supports skills, you can use Email Design Review with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Email Design Review AI skill free?

Yes. It is published on GitHub by kingadow under the MIT license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
