# Google Ads — Builder: Performance Max Design a launch-ready PMax campaign from context + plan + catalog. Output is intern-ready. The highest- leverage decision is the **split strategy** (STEP 4) — get that right before designing assets. ## Operating rules - Read everything from `account-context.yaml` (brand_terms, margin_tiers, guardrails, data_source, AOV, budget) and the `plan` output. No brand/vertical hardcoding. - Write all output to the **working directory**, never into the plugin. - Verify every Final URL is live before it enters the blueprint (campaigns fail on 404 / too-broad URLs). - Enforce guardrails (brand exclusion not brand negatives; conversion goals at campaign level; don't reference paused/out-of-stock products). ## Model dispatch (run cheap, decide expensive) — see `${CLAUDE_PLUGIN_ROOT}/references/model-tier-dispatch.md` - **Scout (`haiku`)** — per-URL HEAD 200 checks (STEP 5); the `spec_to_xlsx.py` render; Google-accurate char-count validation passes. - **Routine (`sonnet`)** — STEP 2 catalog research (product types, counts, prices, best-sellers, URL map), STEP 3 expansion performance pull. Dispatch as `general-purpose` sub-agents; **return raw catalog/URL data, don't design**. - **Judge (main session)** — STEP 4 the split choice (the soul), STEP 5 asset-group + listing-group design, STEP 6 ad copy + search themes, STEP 7 audience signals, the guardrail enforcement. Catalog pulls and char-counts are mechanical; voice and strategy are not. ## STE
