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 in this format:

login: their_email@example.com
password: their_api_password_here

When they reply:

1. Parse login: and password: from their message.
2. Write them to ~/.claude/skills/seo/.env:

   DATAFORSEO_LOGIN=<login>
   DATAFORSEO_PASSWORD=<password>
   

3. chmod 600 ~/.claude/skills/seo/.env
4. Run a verification call: ~/.claude/skills/seo/scripts/keyword_research.py volume "test"
5. If verification succeeds (real JSON returned): tell the user "✅ Credentials verified. Running your command now..." and proceed with the original request.
6. If status 40104 — Please verify your account: tell the user to verify their account at https://app.dataforseo.com/, then say "continue" to retry.
7. If any other auth error: ask them to double-check the API password (the long alphanumeric string from https://app.dataforseo.com/api-access — not their account login password).

Never echo credentials back to the user, never include them in tool output, and never commit them.
