Steps

  1. Collect input (subagent) — Ref: references/input-and-library.md. Fetch fresh SERP data for the keyword and resolve the keyword library. Returns: saved keyword record with top-10 SERP + metrics.
  2. Winnability assessment (subagent) — Ref: references/winnability-rubric.md. Uses keyword record from step 0. Output template: templates/phase-1-winnability.md. Returns: verdict (Winnable / Challenging / Hard-to-Win), search intent, key signals, recommendation to continue or skip.
  3. Content gap analysis (subagent) — Call analyze_serp(kw, keyword_library, mode: "content_gap_analysis") and return the tool's markdown directly without reformatting. Returns: must-have topics, target length/format, weakness analysis.

After presenting Phase 2, suggest the user run /blog-creator to turn the SERP analysis into a full blog post.
