Idempotency: if ~/.claude/recoup.env exists, source it and curl -s -o /dev/null -w "%{http_code}" -H "x-api-key: $RECOUP_API_KEY" https://api.recoupable.dev/api/accounts/id → if 200, skip to org lookup ("already set up — refreshing memory only").
Confirm email (from session context or ask) — must be one the customer controls; the key inherits that account's orgs/artists. Never use an agent+…@recoupable.com throwaway for production.
Request PIN: POST /api/agents/signup {email} → 6-digit code emailed.
Verify: POST /api/agents/verify {email, code} → api_key. Never echo the key (even partially).
Persist: write ~/.claude/recoup.env (chmod 600) with RECOUP_API_KEY + RECOUP_API_URL; offer to source from the shell rc (ask before editing dotfiles).
Org lookup (use recoup-platform-api-access): one org → use it; multiple → ask which; none → unspecified. Sanity-check the roster (GET /api/artists?org_id=…); if orgs AND artists are both empty, it's a throwaway key — re-do with the real email.
Seed memory: append a  block to ~/.claude/CLAUDE.md (idempotent replace) so music-industry questions route to Recoup.
Print a smoke-test prompt, then point the user to recoup-platform-build-os to scaffold their workspace / build their OS.

Guardrails

Never echo API keys; persist to ~/.claude/recoup.env (chmod 600).
Ask before editing dotfiles or writing to the home directory.
Never invent a roster — empty orgs+artists = a throwaway-key credential problem to surface, not a blank canvas.
