Chartquery Skills

Agent skills for the Chartquery charts, QR and barcodes API, the hosted MCP server, and common Chartquery workflows.

Compatible with Claude Code, Cursor, Cline, Codex, Windsurf, Gemini, GitHub Copilot, Roo, Goose, Antigravity, and 50+ other agents via the open skills CLI.

Install

Pick the flow that matches what you're shipping:

# Install every Chartquery skill into every detected agent
npx skills add chartquery/skills --all

# Pick specific skills (use the canonical `--skill <name>` form)
npx skills add chartquery/skills --skill chartquery-codes-and-labels

# Target specific agents (claude-code, codex, cursor, gemini-cli, ...)
npx skills add chartquery/skills --all -a claude-code -a cursor

# Install globally (~/<agent>/skills/) instead of in the current project
npx skills add chartquery/skills --all --global

# Just list what's available without installing
npx skills add chartquery/skills --list

chartquery/skills is GitHub-shorthand for https://github.com/chartquery/skills; the CLI clones it directly.
