Phase 0: Credential Preflight (REQUIRED — run BEFORE anything else)

Before running any of the steps below, always invoke the shared preflight check:

~/.claude/skills/seo/scripts/preflight.sh

If exit code is 0: credentials are configured — proceed with the rest of this skill silently.

If exit code is 2: the script prints the DataForSEO setup wizard to stdout. STOP, display that wizard to the user verbatim, and wait for them to paste credentials.

When they reply, parse login: and password:, write to ~/.claude/skills/seo/.env (chmod 600), verify with keyword_research.py volume "test", and proceed only after success. Never echo credentials.
