Agents orchestrate skills across plugins — they assess your input, choose a path, and exercise judgment. Skills are single-purpose tools invoked with a slash command. Rules govern every output. Hooks are event-driven automations. Skills are grouped into plugins (installable bundles organized by project lifecycle).

Quick Start

Install

Claude Desktop: Open Customize → Browse plugins → + → Add marketplace from GitHub → enter AlpacaLabsLLC/skills-for-architects

Claude Code:

claude plugin marketplace add AlpacaLabsLLC/skills-for-architects
claude plugin install 01-site-planning@skills-for-architects

Use

Type /studio followed by what you need. The router reads your request and hands off to the right agent or skill.

/studio task chair, mesh back, under $800
/studio 123 Main St, Brooklyn NY
/studio I need a space program for 200 people
/studio parse this EPD

Type /skills for the full menu. Or call any skill directly by name (e.g. /environmental-analysis 123 Main St).

Agents

Agents are the orchestration layer. Describe your task — the agent decides which skills to call, in what order, and what judgment to apply.

| Agent | Domain | What it does | |-------|--------|-------------| | site-planner | Site Planning | Runs all site research in parallel, synthesizes a unified brief with opportunities and constraints | | nyc-zoning-expert | Due Diligence + Zoning | Full NYC property and zoning analysis — due diligence, buildable envelope, 3D visualization | | workplace-strategist | Programming | Translates headcount and work style into space programs — occupancy compliance, zone allocation, room schedules | | product-and-materials-researcher | Materials Research | Finds products from a brief, extracts specs from URLs/PDFs, tags and classifies, finds alternatives | | ffe-designer | FF&E Design | Builds clean schedules from messy inputs, composes room packages, runs QA, exports to dealer formats | | sustainability-specialist | Sustainability | Evaluates environmental impact — finds EPDs, compares GWP, checks LEED eligibility, writes spec thresholds | | brand-manager | Presentations | Owns visual identity — builds decks, creates palettes, QAs deliverables for presentation readiness |
