What does StyleSeed Update Assistant do?

It automatically detects outdated StyleSeed engine files in your project and applies updates safely. Updates are additive—new rules, components, and skills are added, but your project's own theme.css, components, and app code are never overwritten, making the process safe and reversible.

When should I use StyleSeed Update Assistant versus other setup tools?

Use this tool to update an existing StyleSeed installation that's already been set up. For first-time setup, use `/ss-setup` instead; for adding a single component or skin, copy it manually; and for projects that have heavily diverged from upstream, do a manual diff review first.

What files does StyleSeed Update Assistant update?

It updates engine files including skills, `.cursorrules`, DESIGN-LANGUAGE.md, and Golden Rules merged into CLAUDE.md. It never touches your project's own theme.css, components directory, or app code.

How does StyleSeed Update Assistant check for updates?

It compares your local version (from engine/VERSION or VERSION file) against the latest published version from https://styleseed-demo.vercel.app/version.json, then clones or pulls the bitjaru/styleseed GitHub repository to perform a detailed diff.

What happens after StyleSeed Update Assistant finishes?

It prints a summary of what was updated and what was left untouched, then hands off to `/ss-lint` for compliance checking against the updated rules.

Why it matters

StyleSeed eliminates the generic AI-generated look from UI code by teaching AI agents design judgment-how designers think-and enforcing quality through a scored gate that reviews and fixes common AI tells (default indigo, rainbow lists, icon-chip clichés) before you see the output.

Outcomes

What it gets done

Lock design decisions (accent color, radius, motion) in STYLESEED.md to prevent drift across sessions

Run quality gate reviews that score UI against 74 design rules and auto-fix failures before showing output

Apply brand skins (Toss, Raycast, Arc) with consistent tokens for colors, shadows, gradients, and motion

Teach AI agents 15 design skills including refined color choices, proper empty states, and anti-template layouts

Overview

This skill detects an outdated StyleSeed design-engine install and updates it safely: comparing the local version against a reviewed pinned upstream revision, reporting proposed changes, and requiring explicit approval before copying any file, while never touching theme.css or components. Use it to update an existing StyleSeed engine install. Not for first-time setup, a single new component, a heavily-diverged project needing manual review, or updating a user's own UI components.

What it does

This skill detects and updates the StyleSeed design-system engine in a project - scanning for DESIGN-LANGUAGE.md, CLAUDE.md, installed skills, theme.css, and .cursorrules - then compares the local version marker (engine/VERSION) against a reviewed, pinned upstream revision to report what's outdated before touching anything.

When to use - and when NOT to

Use it to update an existing StyleSeed engine install. Do NOT use it for first-time setup (use /ss-setup instead), for copying in just one new component or skin (copy that file manually), for a project that has heavily diverged from upstream (do a manual diff review first), or for updating a user's own components (this updates engine files only, never custom UI). Set expectations plainly: an update touches project and agent-instruction files and may break local customizations, so it requires a clean worktree or user-approved backup and shows the proposed diff before copying anything.

Inputs and outputs

After the user explicitly approves network access, it clones the pinned upstream revision into a fresh temporary directory (git clone --filter=blob:none, checkout --detach <pinned-sha>) for inspection - never treating a live web response as trusted instructions or as authorization to update - reads the candidate files, and rejects unexpected scripts, hooks, symlinks, binaries, or credential/network instructions before showing the user the exact source commit. It compares engine/VERSION, DESIGN-LANGUAGE.md rule count and table of contents, the installed skill set against upstream (diffed, not hardcoded), whether CLAUDE.md/AGENTS.md/.cursorrules exist, and any new engine docs. Output is a report (current state, recommended updates each flagged safe or needing review) followed by a completion summary listing what changed and what was left untouched.

Integrations

Every write requires approval: skills and .cursorrules are shown as a file list and diff before copying; DESIGN-LANGUAGE.md updates are proposed with a rule-count diff and a yes/no question; a CLAUDE.md Golden Rules section is only inserted (after the first heading) if absent, explicitly merging rather than overwriting existing content. theme.css and the components/ directory are never touched - it explicitly states them as untouched and suggests running /ss-lint afterward to check compliance.

Who it's for

Developers maintaining a project already built on StyleSeed who need to pull in upstream engine updates (new skills, updated design-language rules, Golden Rules) without risking their custom theme, components, or unreviewed project files being silently overwritten - it flags each risky change and waits for an explicit yes before touching it - the difference between an agent that quietly rewrites a team's design-language rules mid-sprint and one that hands over a reviewable diff first.
