Auto-detects which agent CLI you have (claude / codex / gemini) and installs all 9 Upstage skills into the right location. See INSTALL.md for flags (--target, --skill, --scope, --dry-run) and per-harness setup.

# Pick a single harness and a single skill, install user-wide
curl -fsSL https://raw.githubusercontent.com/UpstageAI/upstage-extensions-hub/main/install.sh \
  | bash -s -- --target claude --skill upstage-ocr --scope user

# Or clone and run locally
git clone https://github.com/UpstageAI/upstage-extensions-hub.git && cd upstage-extensions-hub
./install.sh --list      # see what's available
./install.sh --help

What you get

Nine Agent Skills, all auto-triggering based on conversation context. Same SKILL.md format works across all three harnesses.

upstage-builder	Multi-API orchestrator — build RAG flows, agents, and full web services with Solar + embeddings + Document AI
upstage-solar-delegation	Delegate long-form generation to Solar Pro3 while keeping the primary model for planning and tool calls
upstage-document-parse	Parse PDFs/images/DOCX/PPTX/XLSX/HWP into layout-aware markdown or HTML with tables, figures, bounding boxes
upstage-ocr	Plain-text OCR with word-level bounding box coordinates
upstage-information-extraction	Extract named fields (invoice total, supplier name, …) via custom JSON schemas or prebuilt models
upstage-document-classification	Sort documents into user-defined categories; split multi-document PDFs
upstage-schema-generation	Generate JSON schemas for downstream Information Extraction
upstage-studio	Run Document Agent API (v2) workflows — Studio agents (agt_xxx) or programmatic Agents/Configs
botmadang	Korean AI-agent community (botmadang.org) — post, comment, vote, browse
