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: [email protected]
password: their_api_password_here

When they reply:

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

`` DATAFORSEOLOGIN=<login> DATAFORSEOPASSWORD=<password> ``

1. chmod 600 ~/.claude/skills/seo/.env
2. Run a verification call: ~/.claude/skills/seo/scripts/keyword_research.py volume "test"
3. If verification succeeds (real JSON returned): tell the user "✅ Credentials verified. Running your command now..." and proceed with the original request.
4. If status 40104 — Please verify your account: tell the user to verify their account at https://app.dataforseo.com/, then say "continue" to retry.
5. 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.

SEO Content Authority Skill

Powered by: DataForSEO API — Labs rankedkeywords + Labs competitorsdomain + Labs domain_intersection.
Cost: ~$0.05 per run.

Run

Pull what the target ranks for, plus the top competitor's ranked keywords:

~/.claude/skills/seo/scripts/domain_overview.py ranked --target <domain> --limit 200
~/.claude/skills/seo/scripts/domain_overview.py competitors --target <domain> --limit 5
~/.claude/skills/seo/scripts/domain_overview.py content_gap --you <domain> --competitors <c1> <c2> <c3>

Topic clustering

Group keywords into topical clusters using common stems / shared head terms. Don't be too granular — aim for 8-15 clusters max for a typical site.

Example clusters for an SEO tool site:

• "keyword research" (head: keyword)
• "rank tracking" (head: rank, ranking)
• "backlinks" (head: backlink, link building)
• "site audit" (head: audit, technical)
• ...

For each cluster, classify it

Content Score (0-100)

content_score = round(
    50 * (strong_clusters / total_clusters) +
    25 * (1 - missing_clusters / total_clusters) +
    25 * (avg_position_top_quartile_score)
)

Highest-leverage content moves

Surface the top 5 specific articles to write next. Pick from the "Missing" and "Building" clusters, prioritizing keywords with:

• Search volume > 200/mo
• Difficulty < competitor's domain rank
• Commercial or transactional intent

For each, suggest: working title, target keyword, related keywords to include, estimated word count.
