Install IDE agent skills

Give Cursor and Claude Code ready-made procedures for Marshal and Relay by installing the open exemplar-skills  package from GitHub.

The skills teach agents how to connect MCP, use the SDK/CLI, and stand up Relay policy—so engineers can start from a chat instead of hunting docs.

Source: github.com/Exemplar-Dev/exemplar-skills 

Install from GitHub

No npm registry publish is required. npx clones the repo and runs the installer (or the skills CLI installs from GitHub directly).

Installer (npx + GitHub)

Copies skills into .cursor/skills, .claude/skills, and .agents/skills in the current project:

npx github:Exemplar-Dev/exemplar-skills

Useful variants:

# Global (all projects)
npx github:Exemplar-Dev/exemplar-skills --global
 
# One skill / one agent
npx github:Exemplar-Dev/exemplar-skills install exemplar-harness -a cursor
 
# List bundled skills
npx github:Exemplar-Dev/exemplar-skills list

Equivalent:

npx --yes git+https://github.com/Exemplar-Dev/exemplar-skills.git

skills CLI

npx skills add Exemplar-Dev/exemplar-skills --all
npx skills add Exemplar-Dev/exemplar-skills --skill exemplar-harness -a cursor -y
npx skills add Exemplar-Dev/exemplar-skills --list

These are IDE-local skills (SKILL.md folders). Org-wide versioned skills still live in Marshal Skill management and the exemplar skills CLI. Use both: local skills bootstrap the IDE; the registry shares team procedures across channels.

After install

  1. Open Cursor or Claude Code (prefer --global install for Relay so all workspaces get the skill).
  2. Ask to set up Exemplar Marshal MCP (/exemplar-harness), or Relay Connect (/exemplar-relay / “Set up Exemplar Relay”).
  3. For Relay: create a personal API key with RELAY scope in Account Settings — Tokens (not org-only). The skill exports EXEMPLAR_API_KEY and installs hooks (global or project).
  4. For Marshal MCP: create an org API key as needed, then point the IDE at MCP using Connect clients.
  5. Control rules and Behavior Guards: Relay getting started and Connect surfaces. Manual fallback: Console Relay → Connect.
  6. For framework SDK integrations, point at Live SDK examples (live demos, not simulated).
