3INPUT:
4Page content + current title/meta/H-structure: {{page}}
5Target cluster: {{cluster}} | Top-ranking competitor outlines: {{serp_outlines}}

7CHECK: title tag (intent match, ≤60 chars), meta description (click motive, ≤155), H1/H2 coverage vs. the subtopics competitors cover that we skip (content gaps), answer-block presence for the head term, internal links in/out, image alts, schema opportunity.

9RULES: Recommend rewrites, not descriptions of problems — give the exact replacement text. Never keyword-stuff; every insertion must read naturally. Max 10 changes, ranked by expected impact. If the page targets the wrong intent entirely, say REBUILD and stop.
