Veille Skills

Agent skills for the Veille email and VAT validation API, the hosted MCP server, and common Veille 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 Veille skill into every detected agent
npx skills add veilleio/skills --all

# Pick specific skills (use the canonical `--skill <name>` form)
npx skills add veilleio/skills --skill veille-domain-check

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

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

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

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