How it works
Run the audit
Lyse reads your tokens, components, and stories. No config. No API key. Health Score in 30 seconds.
Score every PR
Lyse posts a Health Score on every pull request. SARIF lands in your Security tab. Drift can't ship silently.
Brief your agents
Lyse runs as an MCP server. Cursor, Claude Code, and Codex query it before writing code. No hallucinations.
Features
Lyse handles the audit. Your team keeps every design decision.
Trust
No black box. No silent rewrites. Every drift, every score, every fix — auditable, reversible, yours.
Local-first
Lyse runs entirely on your machine. Your source code never leaves your laptop. No telemetry, no API key, no account.
Deterministic outputs
Lyse uses an open, versioned formula. Same repo, same score, every run. A determinism gate runs in CI.
Human-in-the-loop
Lyse fix only proposes codemods — you review the diff like any PR. Six safety guards before anything ships.
Your design system is now read by machines. We're building the open infrastructure that makes it AI-ready.
FAQ
What DS Leads ask us in discovery calls.
What does the Health Score actually measure?
Six weighted axes — tokens, components, accessibility, stories, naming, and AI-surface readiness. Each axis aggregates specific rules with transparent formulas. Plus a CMMI-style maturity tier. Open formula in docs/health-score.md.
Will Lyse work with my tokens?
Yes. Lyse reads Style Dictionary, Tokens Studio, Tailwind v4 @theme, DTCG JSON, and CSS variables. If your build can find them, Lyse can too.
Will my repo's score show up on the public Score Live?
Never. The Bench audits open-source repos only. Your internal score stays on your laptop and in your CI. Lyse Labs never receives it.
How do my AI agents actually use Lyse?
Two paths. Static: `lyse agents > AGENTS.md` writes a contract your IDE reads. Live: `lyse mcp` runs an MCP server that Cursor, Claude Code, and Codex query — `audit_file` + `suggest_fix` in real time.
My design system isn't perfect yet. Will Lyse just shame me?
You always have the final call. Lyse proposes; you approve. Start with one sprint. See the quality of the proposals. No. Lyse renormalizes when an axis doesn't apply — no Storybook? That axis is N/A. You get a partial score plus a CMMI tier (Foundational → Autonomous) to track progress over time.
Is Lyse going to be around in 2 years?
The code is AGPLv3 — fork-proof. Even if Lyse Labs disappears, you keep the tool. No VC raise, no exit pressure. Commercial license funds development. Building in public.
