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It automatically detects outdated StyleSeed engine files in your project and applies updates safely.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

StyleSeed Update Assistant

A skill that safely updates StyleSeed engine files from a pinned upstream commit, with diff review and per-file approval, never touching theme.css or components. Use it to update an existing StyleSeed installation. Not for first-time setup, single-file additions, heavily diverged projects, or updating your own UI code.

What it does

Detects and safely updates StyleSeed engine files in a project, updating only engine files (skills, DESIGN-LANGUAGE.md, .cursorrules, a merged Golden Rules section in CLAUDE.md) while leaving theme.css and components/ (the user's own skin and code) completely untouched.

When to use - and when NOT to

Use it to update an existing StyleSeed installation. Don't use it for first-time setup (use /ss-setup instead), for adding just one new component or skin (copy that file manually), for projects that have heavily diverged from upstream (do a manual diff review first), or to update your own UI code or components - this only touches engine files, never your customizations. An update can change project and agent-instruction files and may break local customizations, so it requires a clean worktree or a user-approved backup, shows the proposed diff, and gets explicit approval before copying any file - preserving unrelated user work via a scoped backup or revert.

Inputs and outputs

Detection scans for the relevant files:

find . -name "DESIGN-LANGUAGE.md" -not -path "*/node_modules/*"
find . -name "CLAUDE.md" -not -path "*/node_modules/*"
find . -name "theme.css" -not -path "*/node_modules/*"
find . -name ".cursorrules"

Installed skills are also detected (ss-* is current; ui-*/ux-* are legacy names being migrated from). Version checking compares the local engine/VERSION marker against a pinned, reviewed upstream commit - after explicit user approval for network access, it clones that pinned revision (a specific commit hash, not a moving branch) into a fresh temp directory, rejects unexpected scripts, hooks, symlinks, binaries, or credential/network instructions, and shows the user the exact source commit before any file is used. It then reports a categorized update plan (safe / needs review / merge-only) and asks before proceeding, then for each item shows the diff and requires per-file approval before copying - inserting a Golden Rules section into CLAUDE.md only if one doesn't already exist, after the first heading, without touching existing content otherwise.

Integrations

Pulls the reviewed upstream engine from github.com/bitjaru/styleseed, and recommends running /ss-lint afterward to check pages for rule violations against the updated engine. The pinned commit is meant to be re-reviewed before it's ever swapped for a newer revision, rather than tracked automatically.

Who it's for

Teams running StyleSeed-based projects who need engine updates applied safely and incrementally - with diff review and explicit per-file approval - without ever touching their own theme or component code.
