Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

google-ads-builder-pmax scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/spec_to_xlsx.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 171 lines — stays where its author put it; the contents beside it link to each section on GitHub.

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.

STEP 1 — Inputs

From the user + plan: which products/lines, the campaign's daily budget, and target ROAS phase. If the user is vague ("build pmax for X"), infer the rest from context and the catalog.

STEP 2 — Research catalog & website

Via the data_source connector/API (Shopify/Woo/...), pull product types, counts, price distribution, and best sellers. Verify collection/landing URLs are live (no 404, correct content) and record a URL map. Capture the website's product-type taxonomy (it may differ from the feed product_type — check both). If the connector is down, use the fallback chain (env creds / hub / browse) per setup; flag and continue.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
