Installation
Step 1: Add the marketplace:
claude plugin marketplace add https://github.com/dlabs/claude-marketplace
Step 2: Install a plugin:
claude plugin install blueprint-dev
claude plugin install design-studio
claude plugin install scenario-testing
This installs with user scope by default (available across all projects). To install for a single project only:
claude plugin install blueprint-dev --scope project
Step 3: Restart Claude Code for the plugin to take effect.
blueprint-dev
Planning-first, design-driven development workflow for Claude Code.
- 26 specialized agents — from architecture review to compound knowledge extraction
- 21 slash commands — full pipeline from
/discover to /compound, plus lightweight fast-lane, batch operations, browser testing, and video walkthroughs
- 15 skills — reference knowledge for planning, A/B testing, trunk-based dev, browser automation, git worktrees, eval framework, and more
- 5 eval suites — skill quality benchmarking with prompt-criteria tests
- 1 hook — automatic stack detection on session start
/blueprint-dev:bp:discover # Detect your stack
/blueprint-dev:bp:plan "feature" # Plan a feature
/blueprint-dev:bp:lfg "feature" # Full pipeline
/blueprint-dev:bp:go "small task" # Fast lane for small work
/blueprint-dev:bp:batch "change" # Parallel codebase-wide changes
/blueprint-dev:bp:test-browser # Browser tests on affected pages
See the full Blueprint-Dev Guide for detailed usage.
design-studio
Code-first design exploration — from product definition to production components.
- 10 specialized agents — product planner, brand builder, screen designer, variant generator, and more
- 12 slash commands — product planning, brand building, screen design, variant picking, token extraction, and Next.js conversion
- 2 skills — design system patterns and product planning methodology
/design-studio:product # Define your product
/design-studio:design-brand # Build a Minimum Viable Brand
/design-studio:design "description" # Generate HTML design variants
/design-studio:design-pick # Pick a variant and extract tokens
/design-studio:design-ship # Convert to Next.js components
scenario-testing
Probabilistic validation for agentic software — where traditional tests fall short.
- 6 specialized agents — scenario writers, satisfaction scorers, digital twin builders, and holdout validators
- 10 slash commands — scenario authoring, execution, satisfaction analysis, and twin management
- 3 skills — scenario patterns, satisfaction scoring, and digital twin methodology
/scenario-testing:author "user story" # Write a scenario from a user story
/scenario-testing:run # Execute scenarios against your system
/scenario-testing:score # Score satisfaction across trajectories
/scenario-testing:twin "service" # Create a behavioral clone of a service
