Pipeline skills stop duplicating domain knowledge — they now read from expertise skills (color, typography, accessibility, icons, visuals). Brand-guidelines hard-gates on WCAG 2.2 AA before finalizing a design system.
The brand pipeline now emits a registry:theme artifact and installs it via shadcn's own apply path — no more nova defaults written first and brand tokens pasted on top.
Recommended install command flips from npx to pnpm dlx (with bunx alongside), and non-interactive installer runs now default to local instead of global.
Fixes a critical bug where the foundations agent had no token-mapping spec, plus brand fidelity gates in design and richer shadcn composition rules in the builder.
GSP is now discoverable via The Agent Skills Directory. Cherry-pick individual skills, updated help output, and a new bento grid reference for project builds.
Two-wave parallel agent orchestration cuts build time by ~47% while adding just 171 tokens (+1.1%) to the pipeline. Components phase, resumable builds, mixed-model rate-limit distribution, and 9 pipeline gap fixes.
Agent stubs drop session-start from 1,536 to 140 lines. Pass-through exec_context eliminated from 6 skills. New benchmark system tracks weight across releases.
Skills split into expertise (knowledge owners) and pipeline (orchestrators). 10 skills consolidated into 5. References colocated. Phase transitions extracted into a dedicated skill.
Style presets gain structured schemas. Identity splits into creative director + 8 domain skills. Critique restructured from design research. 12 prompt stubs consolidated into agent definitions.
Model routing across all 30 skills, SubagentStop hooks for all chunk-producing agents, context optimization rules, and 60 audit tests. The pipeline now routes opus where it matters and sonnet where it doesn't.
First user testing run surfaced two critical issues: brand discovery dumped question walls instead of conversational flow, and global installs broke skills with sibling files. Both fixed, plus 5 new audit tests to prevent regression.
Breaking: monolith format dropped. 337 lines removed across 24 files. Skills trimmed for agent efficiency, accessibility split into focused modes, brand-refine wired into the pipeline.
848 lines trimmed from prompts. Brand feedback loops close the gap between shipped projects and brand specs. Build quality gates catch extraction issues. Visual taste scoring sits alongside usability heuristics.
Brand visual DNA now flows into designer and builder agents. New CSS visual effects and block patterns references. Imagery pipeline matches brand style across all phases. Update and statusline detection fixed.
GSP is now a Claude Code plugin with a full manifest, MCP servers, and hooks. The multi-runtime installer supports OpenCode, Gemini CLI, and Codex. New composable skills for accessibility, palettes, type scales, and design system scanning.
Refactored from a single pipeline to the dual-diamond model. Full branding pipeline from research through system, plus /gsp:doctor for project health diagnostics and a design trend index with 9 enriched trend files.
Agents now produce 50-200 line chunks with INDEX.md manifests instead of monolithic files. The pipeline is codebase-aware, routing strategy based on what it finds in your project.
