memi

Read-only design engineering for coding agents.

Memi is the read-only design engineering audit and skill layer for coding agents. It gives Codex, Claude Code, Cursor, Grok Build, and MCP clients file-anchored interface evidence before they edit UI.

Memi reads the product you already have, identifies accessibility, hierarchy, state, responsive, motion, and token risks, then reruns the same deterministic check after a fix. Your code remains the source of truth.

Supported today: Node 20, 22, and 24 on macOS, Linux, and Windows. Figma and Studio are optional companions.

Quickstart

Run one audit in any frontend repository:

npx -y @memi-design/cli@2.6.4 diagnose . --json --no-write --fail-on none

You get a score, normalized finding IDs, confidence, provenance, and file:line evidence. No account, API key, Figma file, global install, or daemon is required.

Keep the workflow available to your coding agent:

npx skills add memi-design/memi --skill audit-frontend-design

Then ask:

Audit this frontend before editing it. Prioritize the five fixes that will matter most to users.

Focused skill	Use it when
audit-frontend-design	Find interface risks before changing UI
remember-design-system	Load compact product-system context
enforce-design-ci	Gate pull requests with deterministic evidence
build-swiftui-interface	Build and verify native Apple interfaces

Compatible with the shadcn registry and v0 design systems.

If Memi catches a real interface issue in your project, star the repository and share the finding. That is the most useful signal for deciding what to improve next.

What Memi catches

Signal	Example evidence
Accessibility	Missing labels, reduced-motion fallbacks, focus and contrast risks
Interface craft	Weak hierarchy, spacing drift, brittle responsive behavior
Product states	Missing loading, empty, error, success, and permission states
Design systems	Token drift, raw values, inconsistent component usage
Routes and components	App graph, duplicated patterns, risky change surfaces
Pull requests	New debt only, SARIF annotations, step summary, HTML report

The first command is deliberately read-only. Write-capable scaffolds and Figma operations are separate, explicit workflows.

How it works

1. Inspect - build an evidence graph from source, routes, styles, and local design-system files.
2. Find - report normalized issues with severity, confidence, provenance, and file:line.
3. Correct - let a human or coding agent make a scoped change.
4. Verify - rerun the same command and compare the evidence.

No LLM is used in the deterministic CI enforcement path.

Choose your integration

Surface	Start here	Best for
One-time CLI audit	npx -y @memi-design/cli@2.6.4 diagnose . --no-write	Trying Memi without installing
Global CLI	npm i -g @memi-design/cli	Daily local use
Agent Skill	npx skills add memi-design/memi --skill audit-frontend-design	Codex, Claude, Cursor, and compatible agents
GitHub Action	uses: memi-design/memi@ec4d804220bfbf08be810ceb692a338cf186e794	Pull-request design CI
MCP server	memi mcp start --no-figma	Any MCP client
Studio	brew install --cask memi-design/memi/memi-studio	Supervised macOS workflows

The CLI and focused skills are primary. Studio, Figma, research, scaffolding, registries, and the larger tool router are deeper paths.

Design CI

Pin the release commit so every pull request runs the same code:

name: design
on: [pull_request]

permissions:
  contents: read

jobs:
  memi:
    runs-on: ubuntu-latest
    permissions:
      contents: read
      security-events: write
    steps:
      - uses: actions/checkout@3d3c42e5aac5ba805825da76410c181273ba90b1 # v7.0.1
        with:
          fetch-depth: 0
      - uses: memi-design/memi@ec4d804220bfbf08be810ceb692a338cf186e794 # v2.6.4
        with:
          version: "2.6.4"
          report: true
          upload-sarif: true

The Action adds code-scanning annotations, a step summary, and a memi-design-health artifact. Existing debt can be baselined while new debt fails the gate.

Agent and MCP setup

Install a complete project kit:

memi agent install codex --project .
memi agent install claude-code --project .
memi agent install cursor --project .
memi agent install grok-build --project .

Start the local MCP server without Figma:

memi mcp start --no-figma

{
  "mcpServers": {
    "memoire": {
      "command": "memi",
      "args": ["mcp", "start", "--no-figma"]
    }
  }
}

Codex plugin marketplace:

codex plugin marketplace add memi-design/memi --ref main --sparse .agents/plugins --sparse plugins/memoire
