Audit

Google Ads — Audit

Read-only diagnostic. Score the account, surface issues by severity, and — critically — never fire a finding on an unverified assumption. Reuse the live MCP detection proven in setup.

STEP 0 — Load context (MANDATORY, before any scoring)

1. Read account-context.yaml from the working directory. If missing, run setup first.
2. Pull from it: google_ads.customer_id, brand_terms, competitor_terms, margin_tiers, data_source (for landing-page URL checks), measurement, and guardrails.
3. Output is written to the working directory (GOOGLE-ADS-AUDIT.md), never into the plugin.

⚠️ The six guards (apply to EVERY check — they prevent the most common wrong findings)

These are generic; guardrails in the context may strengthen or add to them. Honor both.

• GUARD-1 Conversions — check the WHOLE picture, not the action list. Inspect campaign-level conversion goals + which actions each active campaign actually fires (segment by segments.conversion_action_name), and each action's source. A primary action no campaign uses is inert; a second purchase action kept secondary (e.g. GA4 purchase alongside the Shopify channel "App Purchase") is the CORRECT anti-double-count setup, not a bug. Only flag a real micro-conversion goal or two value-carrying purchase sources both primary and both firing. Before flagging ANY conversion-action contamination (out-of-brand / micro / duplicate), check primary_for_goal. A non-primary action does not enter Smart Bidding and does not affect performance — it's harmless; surface it as a NOTE (tidy-up), never a scored finding. Only a PRIMARY out-of-brand/micro action that an active campaign optimizes toward is a real issue. See ${CLAUDE_PLUGIN_ROOT}/references/conversion-tracking-logic.md.
• GUARD-2 Negatives — FOUR sources, merge ALL. (1) campaign_criterion (negative=true) — campaign-level; (2) campaign_shared_set → shared_set → shared_criterion — SHARED LISTS (the bulk: e.g. "Account Level Negative", "OPI Negative", brand blocks); (3) customer_negative_criterion — ACCOUNT-LEVEL negatives applied account-wide; (4) campaign_criterion.brand_list.shared_set — brand exclusions. Only flag a gap if terms are absent across ALL FOUR; if a shared/account list covers them, cite it, don't flag. A campaign_criterion-only pull is the #1 false-positive in this audit — it looks "thin" when coverage is actually 100+ terms/campaign. After merging all four, declare pulled:[...,"negatives_complete"] so the report renders a real verdict; without that assertion a campaign-only bundle renders VERIFY (re-pull), never a false "weak negatives".
• GUARD-3 Budget scaling — check change_event first. Before recommending a budget/bid increase, pull recent change history (~14d). A recent budget/bid/asset/structure change → recommend cooldown, not scale. (Strengthen with any change-event-cooldown guardrail in context.)
• GUARD-4 Ad strength — confirm ENABLED + impressions. Before flagging POOR ad strength, confirm ad_group.status AND ad_group_ad.status are ENABLED and the group has impressions. Paused = intentional; do not flag.
• GUARD-5 ROAS — apply margin tiers from context. Read margin_tiers; a line with a tier accepts its min_roas (house brands run lower ROAS by design). Never apply a generic ROAS threshold to such a line or a strategic campaign. If unsure, ASK rather than flag.
• GUARD-6 No false "absence". MCP results can be truncated (token cap or your limit). Before claiming "no video / no signal / no negative / no X", re-query filtered on the enum NAME (e.g. field_type = 'YOUTUBE_VIDEO') or pull with returned-rows < limit (proof of completeness). NEVER infer presence/absence by decoding enum integers from memory. Track failed fetches as a G-SYS1 diagnostic; never silently skip a check — explain why data is unavailable.

Audit scope — only what's LIVE in the window (build this FIRST, before any check)

Establish the active campaign set: campaigns that are ENABLED AND had impressions > 0 during the audit window. Exclude removed, paused, and ENABLED-but-dormant (zero-impression / long-off) campaigns. Then scope EVERY other pull to that set — asset groups, ad groups, ads/ad-strength, keywords, search terms. Entity-level status = ENABLED is NOT sufficient: a campaign turned off years ago can still contain ENABLED asset groups / ad groups, and auditing them produces stale, misleading findings. Filter downstream queries by campaign.id IN (active set), or pull them WITH metrics over the window and drop zero-impression rows app-side (metrics can't go in a GAQL WHERE). Never audit a campaign that hasn't served in the window.

Model dispatch (run cheap, decide expensive) — see ${CLAUDE_PLUGIN_ROOT}/references/model-tier-dispatch.md

• Scout (haiku) — STEP 0 context read; the money_leak_report.py render (→ the single AUDIT.html) after the Judge writes audit-result.json; single URL/landing 200 checks.
• Routine (sonnet) — build the active-campaign set; the account data-bundle pull (campaigns, assets, change history); the dual-source search-term pull (per-PMax campaign_search_term_insight loop). Dispatch as general-purpose sub-agents (they keep MCP); tell them to return raw rows, not score.
• Judge (main session) — applying GUARD-1…6, every PASS/WARN/FAIL call, the score, the Gap-to-100 ledger, Quick Wins. Never delegate a guard or a verdict — a Scout pulls numbers, the Judge says what they mean.

Process

1. Pre-flight: load context + guards; build the active campaign set (above); stage the GUARD data pulls (campaign conversion goals, merged negatives, change_event, ad_group.status) scoped to it.
2. Collect account data via the Google Ads MCP, scoped to the active campaign set. Honor GAQL gotchas in ${CLAUDE_PLUGIN_ROOT}/skills/audit/references/gaql-notes.md (dedup keywords; ENABLED-only + impressions-in-window; explicit YYYY-MM-DD date ranges; search_term_view can't use a 90-day DURING). MANDATORY pulls — a missing one = a false finding, not a clean account (this is the checklist a dispatched Scout MUST be handed in full):
   • campaigns + metrics (active set), budgets, bidding strategy + tROAS
   • conversion_action (account) + per-campaign segments.conversion_action_name usage (GUARD-1)
   • asset_group / ad_group_ad ad-strength; keyword_view + Quality Score (deduped)
   • campaign extensions coverage (D9): SELECT campaign.id, campaign.status, campaign_asset.field_type, campaign_asset.status FROM campaign_asset WHERE campaign.status='ENABLED' AND campaign_asset.status='ENABLED'. field_type gives the coverage (SITELINK / CALLOUT / STRUCTURED_SNIPPET / PRICE / IMAGE). Two gotchas, both seen live: (1) campaign.status MUST be in the SELECT because it's filtered (else EXPECTED_REFERENCED_FIELD_IN_SELECT_CLAUSE); (2) do NOT also select asset.type here — it throws INVALID_ARGUMENT on many MCPs (pull asset text separately if needed). Count field_type per campaign (not just presence) so "thin extensions" findings use real counts. If it still errors, flag extensions UNVERIFIED — verify in UI, never assume present/absent.
   • search terms both sources: search_term_view + per-PMax campaign_search_term_insight
   • negatives from ALL FOUR sources (GUARD-2) — NOT just campaign_criterion: (a) campaign_shared_set (which shared lists attach to each campaign — count only status=2 ENABLED; many lists are status=3 REMOVED/old) → shared_criterion (the terms in each ENABLED list); (b) customer_negative_criterion (account-level negatives applied to every campaign — a separate resource, easy to miss; the first ND pull omitted it and produced a false "weak negatives" finding that had to be corrected mid-audit). A brand block / cross-brand block / location block usually lives in a SHARED or ACCOUNT-level list, so a campaign_criterion-only pull shows "no negatives" when coverage is actually extensive. Never flag G07/G14/G-PM5/G-PM6 (brand exclusion / negative coverage) without having pulled shared_criterion AND customer_negative_criterion. After merging, declare pulled:[...,"negatives_complete"].
   • PMax Brand exclusions are a SEPARATE layer from negative keywords — pull them explicitly: campaign_criterion selecting campaign_criterion.brand_list.shared_set + .negative (filter campaign_criterion.brand_list.shared_set IS NOT NULL), then resolve each shared_set.name. These rows have an EMPTY keyword.text, so a keyword-text-only pull DROPS them and you'll wrongly report "no brand exclusion". Check whether a brand list matching the own brand (a list named after the own brand) is excluded on each PMax campaign. An account can run BOTH a brand negative-keyword list AND a brand-list exclusion (belt-and-suspenders) — read both before judging.
   • change_event (~14d)
   • channel split (D8): segments.ad_network_type per campaign — this WORKS for PMax too (network 2 Search/Shopping dominates; small YouTube/Display/cross). NEVER report channel as "verify in UI". Pull metrics.conversions alongside cost — a cost-only pull makes every network look like 0-conv burn.
   • device split (D10): segments.device per campaign (2 Mobile · 3 Tablet · 4 Desktop · 5 CTV · 6 Other).
   • dayparting (D3/D4): segments.hour + segments.day_of_week per campaign + metrics — for the hourly heatmap and best/worst hour/day. And ad schedule: campaign_criterion.ad_schedule.* + bid_modifier (a flat bid_modifier=0 across the window = NO dayparting bid strategy — a real opportunity finding).
   • geo — ALL regions (D3): geographic_view scoped to active campaigns, metrics.cost_micros > 0, no top-N limit. Then resolve EVERY segments.geo_target_region id to a name via geo_target_constant (id, name, canonical_name). Raw geoTargetConstants/NNNNN ids in the report = an unfinished pull, never ship them.
   • asset TEXT + per-asset metrics (D9) — pull the TEXT and cost, NOT just counts (a counts-only pull is wrong; the verbatim text + per-asset spend is what surfaces "this headline spent $X at 0 conv"): SELECT campaign.id, asset_group_asset.field_type, asset.text_asset.text, metrics.cost_micros, metrics.conversions, metrics.conversions_value, metrics.clicks FROM asset_group_asset WHERE campaign.status='ENABLED' AND asset_group_asset.status='ENABLED' AND segments.date BETWEEN ... (HEADLINE ft2 / DESCRIPTION ft3 / LONG_HEADLINE ft18). asset_group_asset DOES return per-asset metrics — a text-only or count-only pull just looks empty (gaql-notes). For Search RSAs, ad_group_ad.ad. responsive_search_ad.headlines is a RepeatedComposite the serializer can't return — get RSA asset text + metrics from ad_group_ad_asset_view instead (don't write "verify in UI"). The ONLY genuine UI-only asset field is asset_group_asset.performance_label (UNRECOGNIZED on some API versions).
   • extension TEXT (D9) — not just field_type counts: pull the sitelink/callout/snippet/price text so the report shows the actual extensions. Either campaign_asset joined to the asset text fields (asset.sitelink_asset.link_text, asset.callout_asset.callout_text, asset.structured_snippet_asset.values, asset.price_asset.*) or the asset resource by id. bundle key ext_text:[{campaign_id,field_type,text}].
   • conversion lag (D12): segments.conversion_lag_bucket — the "can I trust short-window ROAS?" gate.
   • settings & measurement that DO read (pull these — they were once wrongly punted to UI): location type campaign.geo_target_type_setting.positive_geo_target_type — official enum: 5=PRESENCE_OR_INTEREST, 6=SEARCH_INTEREST (both leaks → recommend Presence-only), 7=PRESENCE (correct, NOT a leak). Do NOT invert this: 7 is the GOOD value. (Verified live + against the v21 proto 2026-06-28.) Enhanced Conversions customer.conversion_tracking_setting.enhanced_conversions_for_leads_enabled
     • .accepted_customer_data_terms; final URLs via landing_page_view / expanded_landing_page_view; RSA text + per-asset metrics via ad_group_ad_asset_view; placement exclusions via campaign_criterion.placement.url; content-label exclusions (digital content labels DV-G/PG/T/MA) via campaign_criterion WHERE type='CONTENT_LABEL' (content_label.type) — this READS; an empty result = none configured, NOT unreadable (do not punt it to UI). bundle key content_labels:[{campaign_id,content_label_type}]. (Exact queries: references/gaql-notes.md.)
   • competitive pressure — impression share (PUBLIC, always pull) (D-competitive): per active campaign pull metrics.search_impression_share, metrics.search_rank_lost_impression_share, metrics.search_budget_lost_impression_share (+ abs-top) with a date range. rank-lost IS = losing the auction to COMPETITORS on Ad Rank; budget-lost IS = losing to budget (a scaling lever). Put on each active_campaigns row. These are public metrics — never punt to UI.
   • competitor DOMAINS — Auction Insights (try, then degrade) (competitor input): the "phiên đấu giá" competitor list IS in the API — segments.auction_insight_domain + metrics.auction_insight_search_* (impression_share / overlap_rate / outranking_share / position_above_rate / top & abs-top %). BUT these are RESTRICTED "not publicly available" metrics → most dev tokens get METRIC_ACCESS_DENIED unless Google allowlisted the token. So: TRY the pull; on success write bundle key auction_insights:[{domain, impression_share,overlap_rate,outranking_share,position_above_rate}] (the report renders a Competitors card and you MERGE the domains into the setup competitor list). On METRIC_ACCESS_DENIED, do NOT call it an API gap — note "Auction Insights metrics not allowlisted on this token" and fall back to the impression-share signal above + the competitors the user gave at setup. (Set meta.own_domain so your own row is tagged.)
   • ⚠️ "verify in UI" is ONLY these confirmed-blocked fields (every variant tested 2026-06-28) — do NOT mark anything else UI-only: Final URL Expansion toggle (url_expansion_opt_out UNRECOGNIZED), asset automation (asset_automation_settings PROHIBITED/RepeatedComposite), the video brand-safety inventory mode (campaign.video_brand_safety_suitability UNRECOGNIZED on this version — Expanded/Standard/Limited), PMax asset_group_asset.performance_label (UNRECOGNIZED — use asset_group.ad_strength + per-asset cost/conv), and Consent Mode v2 / server-side-CAPI (tag-side by design — verify in GTM, NOT a pull failure). EVERYTHING ELSE is in the API: a fetch that returns nothing = wrong method (field/resource/missing metrics.*/enum-to-drop), retry — see references/gaql-notes.md. A "we can't see it, check the UI" on API-available data is the #1 way this audit loses a user's trust.
   • GAQL gotcha: any field used in a WHERE filter MUST also appear in the SELECT clause, or the API returns EXPECTED_REFERENCED_FIELD_IN_SELECT_CLAUSE (e.g. filtering on campaign.status requires selecting it). If a field is rejected, drop just that field and re-run — don't abandon the whole pull.
   • COMPLETENESS — loop every campaign, never truncate. Per-campaign pulls (asset_group_signal, asset_group_asset, campaign_search_term_insight) must cover ALL PMax/Search campaigns — do NOT stop "to save time" at the first few. A partial pull (e.g. signals for 3 of 7 PMax) makes the generator emit FALSE "0 audience signals" findings for the un-pulled ones. Big results: save to a file + parse, don't drop.
   • DECLARE what you pulled. bundle.json MUST carry a top-level pulled: [...] listing every dimension you FULLY pulled (all campaigns) — e.g. ["active_campaigns","channel","device","geo","dayparting", "schedule","extensions","signals","negatives","assets","products","conversion_lag","change_events"]. Omit any dimension you could not complete — the generator renders those VERIFY ("not pulled — re-run") instead of fabricating GOOD/FIX. Honesty-by-construction: an absent pulled entry is safe; a half-filled dimension passed off as complete is what burns the user.
3. Validate coverage: confirm ≥30 days of data and a Search Terms Report before scoring; if a source is down, degrade gracefully (flag it, continue) per the fallback chain in setup.
4. Evaluate each applicable check as PASS / WARNING / FAIL — applying GUARD-1…6 so nothing fires on an assumption. Use ${CLAUDE_PLUGIN_ROOT}/skills/audit/references/google-audit-checks.md for the check catalog and severities.
5. Score per ${CLAUDE_PLUGIN_ROOT}/skills/audit/references/scoring-system.md (weighted by severity × category).
6. Report with the per-category Gap-to-100 ledger and an action plan.

Money-Leak deep-dive (MANDATORY — this is what makes the audit worth paying for)

Beyond scoring, run the money-leak diagnostics in ${CLAUDE_PLUGIN_ROOT}/references/diagnostic-playbook.md (D1 bid/target health · D2 budget pacing & allocation · D3 geo waste · D4 dayparting · D5 search-term/spam/ wrong-brand · D6 structure/setup · D7 Quality Score · D8 PMax channel/placement · D9 ad copy/assets/extensions · D10 settings hygiene · D11 audience signals/search themes · D12 conversion-lag gate · D13 change-history timeline · D14 product feed & Shopping performance). For ECOM, D14 is the highest-$ diagnostic. It has THREE layers, each from a different source — degrade cleanly, don't lump them as "needs Merchant":

1. Product PERFORMANCE/identity (Ads, always available) — shopping_performance_view returns full product data through the Merchant LINK (item_id, title, brand, type, condition + cost/impr/conv). The "which product burns / converts" leak. The products ARE in Google Ads — never say "no product data".
2. Out-of-stock (STORE connector) — cross-ref the spending item_ids against the store's live inventory (Shopify/Woo). OOS spenders = pure waste, and this needs NO Merchant connector — only the store you already connected. Do this whenever a store is connected.
3. Approval STATUS (Merchant Content API only) — disapproved / GTIN / policy issues are NOT a GAQL field. If a Merchant connector is present, pull it; if not, flag ONLY this layer as verify-via-Merchant (not the whole of D14). D14 gets its OWN rendered HTML — D14-PRODUCT-CHECK.html — not just markdown. When a store is connected, join the zero-conversion burn products (layer 1) against live store inventory (layer 2) into ONE per-item JSON (one row per burning product) with these fields per item: campaign, title, brand, cost_30d, clicks_30d, imp_30d, product_onlineStoreUrl (the live PDP link — MANDATORY so the user can click to check each SKU), variant_sku, variant_price, variant_compareAtPrice, variant_inventoryPolicy, total_available_all_locations, classification (OOS_DENY | LOW_STOCK | IN_STOCK_NEEDS_PDP_AUDIT), reason. Then render: python ${CLAUDE_PLUGIN_ROOT}/skills/audit/scripts/d14_product_report.py <items>.json --out-dir <workdir> --account "<name>" --window "<range>" → a visual, self-contained D14-PRODUCT-CHECK.html: KPI strip, one color-coded section per classification (OOS=red / low-stock=amber / in-stock=blue), a burn bar per row, and a full SKU appendix where every product title links to its live storefront URL. ALWAYS pull the PDP URL + SKU (product.onlineStoreUrl / variant SKU from the store) — a D14 product list without clickable URLs is incomplete; the user must be able to verify each item in one click. Each diagnostic yields a Money-Leak Report row: leak · evidence (real numbers) · diagnosis (root cause, not symptom) · $/month at risk (formula shown) · exact fix · discipline · confidence. Decode bidding_strategy_system_status FIRST (one field separates budget-capped vs tROAS-too-high vs starved vs learning). A generic "score 85" without these specific, dollar-quantified leaks is the low-value audit we are explicitly NOT shipping. The diagnostics feed both the category scores and the Money-Leak Report in the output.

One-command pipeline (model-tier dispatch) → ONE comprehensive report: dispatch a Routine sub-agent (general-purpose, sonnet) to run the PULL MANIFEST in ${CLAUDE_PLUGIN_ROOT}/skills/audit/scripts/money_leak_report.py (its docstring lists every GAQL query + the bundle.json schema) → it writes bundle.json. Write audit-result.json (the score — STEP 5) into the SAME directory so the generator merges score + money-leak. Then Scout-run python ${CLAUDE_PLUGIN_ROOT}/skills/audit/scripts/money_leak_report.py bundle.json --out-dir <workdir> to generate MONEY-LEAK-REPORT.md + DETAILED-ACCOUNT-REPORT.md AND the single comprehensive AUDIT.html — score donut + grade, the 6 weighted category bars (fixable/unverified findings), money-leak $ chart + findings, a visual per-campaign section (ROAS-vs-target bar with target tick, status pill, channel-split bar, extension/signal chips), Merchant feed table, quick wins, change timeline, verify-in-UI. It auto-detects audit-result.json next to the bundle (or pass --audit-result); without it AUDIT.html degrades to money-leak-only. AUDIT.html is THE — and the ONLY — HTML deliverable: one file, score + full check + leaks + per-campaign visuals together. Do not render any second HTML report (no audit-report.html); there is exactly one HTML output per audit. Then the Judge (you) adds verify-in-UI verdicts. When a pull returns nothing, assume wrong method (field name / resource / missing metrics.* / repeated-enum serialize), not an API limit — retry before writing "verify-in-UI" (see gaql-notes principle).

What to analyze (category weights)

• Conversion Tracking (25%) — campaign-level goals (GUARD-1), Enhanced Conversions, Consent Mode v2, value tracking, attribution, offline import (lead gen), conversion lag. Cross-check Google Ads vs GA4 (flag >35% divergence) when measurement.ga4 is enabled.
• Wasted Spend / Negatives (20%) — review search terms from BOTH sources (search_term_view does NOT contain PMax terms): search_term_view for Search/Branded campaigns + campaign_search_term_insight looped per active PMax/Demand-Gen campaign (it requires a single campaign_id filter; see gaql-notes.md). Merged negative coverage (GUARD-2), brand/non-brand separation (use brand_terms), broad match only with Smart Bidding, geo precision. Source negatives from actual irrelevant search terms; prefer Exact/Phrase; recommend shared lists. Only flag wasted on Search terms with >$10 spend AND 0 conv; for PMax, flag irrelevant categories with clicks but no conversions. Never propose blocking brand terms.
• Account Structure (15%) — business-logic organization, tightly themed ad groups, ≥3 RSAs/group, PMax asset-group/signal structure, naming consistency.
• Keywords & Quality Score (15%) — match-type strategy, QS distribution (≥7 target), cannibalization (watch cross-campaign + use brand_terms), impression share. Apply the legacy-BMM heuristic (BROAD + Manual CPC = legacy, not intentional broad).
• Ads & Assets (15%) — RSA headlines/descriptions count & strength (GUARD-4), pin discipline, extensions (sitelinks/callouts/snippets/image), PMax/AI Max/Demand Gen specifics (below).
• Settings & Targeting (10%) — Smart Bidding vs deprecated ECPC, budget pacing, ad schedule, device adjustments, location = "Presence" not "Presence or Interest", network settings.

Deep dives (only if those campaign types exist)

• PMax — asset-group diversity, audience signals, URL-expansion control, search themes, Insights tab, and brand handling — VERIFY, don't just "confirm". When a Brand Search campaign runs alongside PMax, do NOT flag "missing brand exclusion" on the surface. First DIG IN and check ALL THREE block mechanisms: (a) campaign-level negative keywords (campaign_criterion, negative=true, type KEYWORD); (b) a shared negative list (campaign_shared_set → shared_criterion) — brand blocks are MOST often a named shared list (e.g. "Brand Keywords — do not apply to Branded campaign") applied to PMax + non-brand campaigns and excluded from the Branded campaign; (c) a brand-exclusion brand list (brand-list criteria). Check whether the account's brand_terms are actually blocked by ANY of these. If brand is already blocked → it's a PASS; re-score, don't flag. Only flag G07/G-PM3 if brand terms are genuinely unblocked (and corroborate with G-PM3: are >15% of PMax conversions on brand terms?). Honor any pmax-brand-exclusion guardrail.
• AI Max for Search — campaign.ai_max_setting.enable_ai_max, broad-match+Smart-Bidding combo, search term matching distribution, AI Brief, text-customization rules, FUE controls, brand exclusions. DSA/ACA auto-migration pre-flight (Sept 2026) — stage LOW→HIGH risk; strong negatives are a prerequisite.
• Demand Gen — video+image asset mix, audience signals, funnel-aligned conversion goals (no frequency capping — monitor manually).

Report architecture — PER-CAMPAIGN VISUAL EXPLAINER (see ${CLAUDE_PLUGIN_ROOT}/references/per-campaign-report-template.md)

The audit is a per-campaign visual explainer, not a generic account summary. Document order: Account panel → one chart-rich block per active campaign → Action Plan.

The 3-step rule for EVERY item — ① DATA shown → ② VERDICT (GOOD / WATCH / FIX / VERIFY) → ③ ACTION (only if needed). There is NO separate "money-leak summary" block: the leak IS the verdict+action on the section it belongs to (evaluated inline). Every quantitative metric renders as its own inline-SVG chart, never a wall of text:

• ROAS vs target → semicircle gauge (fill = ROAS, tick = target) · Budget pacing → radial ring
• Channel mix → donut · Device & Geo → horizontal bars colored by ROAS · Schedule → 24-hour heatmap
• Extension/signal counts → meter bars vs the recommended count. Each campaign block shows a scorecard (N good · N watch · N fix · N verify) and covers: performance + decoded bidding_strategy_system_status, channel, device, geo, schedule, products × Merchant, audience signals + search themes, ad copy (headline/description text), extensions with text, negatives + shared lists, final URLs/FUE, change/cooldown — each field marked [API] or [VERIFY] (read-only API can't see it). The account panel lists & rates EVERY account-level setting (conversion tracking, Enhanced Conv, Consent, account/brand negative lists, Content Suitability, structure, conversion-lag) the same 3-step way. Localize per campaign; only cross-campaign / account-wide items (budget misallocation, tracking, content suitability, structure) sit in the account panel. Flat/modern style (no heavy gradients).

The blueprint (every section, its chart, data source, verdict thresholds) is references/per-campaign-report-template.md. The generator (money_leak_report.py) builds it: account panel + Σ(campaign block) + action plan → one self-contained AUDIT.html. It auto-detects audit-result.json next to the bundle for the score + the account panel's category verdicts.

Output — GOOGLE-ADS-AUDIT.md (to the working dir)

1. Health Score 0-100 + grade, with the six category bars.
2. Per-category Gap-to-100 ledger (MANDATORY for any category < 100). Split every non-PASS into:
   • 🔧 Fixable (verified) — check ID, status, severity, points recoverable, concrete fix.
   • 🔍 Unverified — API/MCP can't see it (Enhanced Conversions recording, Consent Mode mode, gtag firing). Do NOT score as FAIL; mark "verify in UI" and state the ceiling if confirmed. A low score driven by unverified items is not breakage — say so.
3. Money-Leak Report (the headline deliverable) — the D1-D14 findings as rows ranked by $/month recoverable, each with evidence + root-cause diagnosis + exact fix + discipline + confidence. Top 3 = Quick Wins. This is what the operator reads first.
4. Detailed Account Report (the differentiated value — granular, not just a score). Beyond the summary:
   • Account summary + what is protecting it (e.g. "no Display burn BECAUSE Content Suitability blocks junk apps" — explain the cause, don't just report the healthy symptom).
   • Per active campaign, a deep ledger: bidding/tROAS + decoded bidding_strategy_system_status, ROAS vs target, channel split (D8), device split (D10), geo top/bottom (D3), dayparting flags (D4), extension inventory — sitelinks/callouts/snippets counts (D9), ad-copy notes incl. duplicates/Ad-Strength (D9), and the settings layer (D10) — Final URL Expansion + URL exclusions, asset automation / text customization, text/brand guideline (exists? appropriate?), content-suitability / placement exclusions, device exclusions. Mark each field API-read or verify-in-UI.
   • Per-campaign Verify-in-UI checklist — the settings the read-only API can't see (FUE, asset automation, content suitability, text-guideline content) listed as explicit checkboxes. Never silently skip a setting.
5. Wasted-spend estimate (monthly $), PMax/AI Max notes.
6. Findings feed optimizer and plan — but audit itself changes nothing.

Also emit a structured result — it feeds the ONE comprehensive HTML report

• Write audit-result.json (schema: ${CLAUDE_PLUGIN_ROOT}/templates/audit-result.json): health_score, grade, per-category scores + fixable/unverified findings, quick_wins, wasted_spend_monthly, notes. Put it next to bundle.json.
• The client report is AUDIT.html from money_leak_report.py (above): a per-campaign visual explainer that auto-merges this score JSON (account panel + category verdicts) with the per-campaign chart blocks (gauge / ring / donut / bars / heatmap) where every item is data → verdict → action. ONE self-contained file. Do NOT ship the score and the money-leak as two separate HTML files — the audit is one document.
• There is exactly ONE HTML report: AUDIT.html. The old score-only audit_to_html.py/audit-report.html path has been REMOVED — do not look for it or generate a second file.

To build / refine later

• Per-campaign visual-explainer AUDIT.html — scripts/money_leak_report.py renders the chart-rich, data→verdict→action report (gauge/ring/donut/bars/heatmap + account panel + scorecards). This is the SOLE HTML report; the legacy audit_to_html.py was removed. Done.
• Full granular check-ID catalog (G01…G61 + extensions) in ${CLAUDE_PLUGIN_ROOT}/skills/audit/references/google-audit-checks.md. Done.
• Vertical-specific benchmark bands in ${CLAUDE_PLUGIN_ROOT}/references/.
• Per-keyword QS + RSA pin/headline-count detail for Search campaigns (currently summarized).
• Geo as a US choropleth (currently colored bars).
