🤖 Agentic Commerce Readiness

Purpose

Audit and prioritize the changes a retailer's catalog, structured data, storefront, and checkout need to be discoverable, comparable, and purchasable by 2026-era autonomous shopping agents (OpenAI Operator / ChatGPT shopping, Anthropic Computer Use, Google Shopping AI + Agent Protocol, Shopify Agent Commerce, Perplexity Shop, and long-tail browser agents). Output is a scored readiness report, a prioritized fix-it backlog with effort × impact, a named 2026-protocol compliance checklist, and a configuration of rate-limit / parity rules — tuned for a merchant whose agent-originated traffic and abandoned-basket rate are both climbing.

When to Use

Use this skill when (a) you see agent-user-agent strings (OpenAI-Agent, Anthropic-CU, GoogleAgent, PerplexityBot-Shop, etc.) in your logs climbing past 3% of product-page traffic, (b) you are preparing for a peak season and want an agent-readable storefront before Black Friday, (c) you just adopted a new ecommerce platform or catalog and want to confirm the JSON-LD / feed pipeline is still correct, (d) you heard about delegated-purchase tokens, merchant-attested agent IDs (MAAI), Shopify Agent Commerce spec, the Machine Payments Protocol (MPP), Visa Trusted Agent Protocol on Web Bot Auth, Mastercard Verifiable Intent, Mastercard Agent Suite, American Express Agentic Commerce Experiences (ACE) Developer Kit, Stripe Link for AI agents, BNPL-on-agent-token (Affirm / Klarna via Shared Payment Token), the Agent Payments Protocol (AP2 — donated by Google to the FIDO Alliance in April 2026), Google's Universal Cart and Universal Commerce Protocol (UCP) Catalog / Loyalty / Post-Purchase capability expansion announced at Google I/O 2026 on May 19–20, 2026, or Gemini Spark (Google's consumer-side personal AI agent rolling out to AI Ultra subscribers in late May 2026) and want to know what actually matters, or (e) your agentic-checkout-fraud-shield skill is flagging high false-positive rates because the merchant side of the handshake isn't configured. Distinct from Product Description Writer (on-page copy), Personalization Strategy (on-site recommendation), Agentic Retail Media Mediation (sponsored-placement layer on agent surfaces), and Agentic Checkout Fraud Shield (risk-side of the same handshake): this skill is the readiness audit of the merchant's public surface and structured data.

Required Input

Provide the following:

1. Product feed or catalog export — CSV, JSON, Google Merchant Center feed, or a link; a sample of at least 50 SKUs covering each top-level category and at least one variant-parent pair
2. Storefront URLs — 3–8 URLs spanning homepage, a category page, 2–3 product pages (including one variant-parent and one item with regulated attributes), cart, and checkout entry
3. Current structured data — JSON-LD / Schema.org markup on each audited page, robots.txt, sitemap.xml, and any robots-agent-specific directives (e.g., GPTBot, OAI-SearchBot, Google-Extended, anthropic-ai, ClaudeBot, PerplexityBot) — or state "none"
4. Target agent platforms — Which agent platforms to support (OpenAI Operator, ChatGPT shopping, Anthropic Computer Use, Google Shopping AI, Google Agent Protocol, Google Gemini Spark personal-agent surface, Google Universal Cart cross-merchant cart surface, Shopify Agent Commerce, Perplexity Shop, Pinterest AI, general crawler-class agents) and the priority order. Use target_protocol_priorities from config.yml to bind the merchant's named priority order across protocols (UCP, AP2, Shopify Agent Commerce, Mastercard Agent Pay, Visa Trusted Agent Protocol, Amex ACE, Stripe Link for AI agents, MPP) so the readiness audit grades each protocol in proportion to the merchant's stated priority rather than treating them as a flat list
5. Inventory and pricing API readiness — Real-time inventory endpoint (yes / no, p95 latency, rate limit), real-time price endpoint (yes / no, p95 latency), promotion / coupon logic exposure (yes / no), and stock-reservation / hold-order capability
6. Checkout stack — Payment stack (Stripe, Adyen, Braintree, Shopify Payments, etc.), passkey / 3DS2 support (yes / partial / no), delegated-purchase token acceptance (yes / no), MAAI header policy (accept / inspect / block), Web Bot Auth signature verification (on / off), Visa Trusted Agent Protocol enrollment (yes / pilot / no), Mastercard Agent Pay + Verifiable Intent acceptance (yes / pilot / no), Mastercard Agent Suite merchant-configuration shape (Q2 2026 GA — merchant-side inventory / margin / promotion / brand-voice rules; in scope / out of scope / pilot), American Express Agentic Commerce Experiences (ACE) Developer Kit enrollment (Agent Registration, Account Enablement, Intent Intelligence, Payment Credentials, Cart Context — yes / pilot / no) and Amex Agent Purchase Protection coverage status (set agent_purchase_protection_coverage_categories in config.yml to enumerate which product categories the merchant has confirmed qualify for Amex Agent Purchase Protection eligibility — typically excludes the regulated categories from input 7 and any category whose return policy does not meet Amex's documented-delivery evidence floor), Stripe Link for AI agents acceptance (yes / no), Machine Payments Protocol (MPP) endpoint exposure for agent-paid microtransactions / recurring (yes / no), BNPL-on-Shared-Payment-Token coverage for Affirm / Klarna / Affirm-Adaptive (yes / no), Agent Payments Protocol (AP2) Payment-Mandate acceptance (yes / pilot / no — covers AP2 v0.2 Human Not Present autonomous-agent payments; Google donated AP2 to the FIDO Alliance April 28, 2026, with named launch merchants Wayfair, Chewy, Quince), Universal Commerce Protocol (UCP) capability set enrolled (Cart / Catalog / Loyalty / Post-Purchase / Ads — Google I/O 2026 May 20 expansion adds Catalog real-time variant-inventory-pricing capability, Loyalty account-linking capability, Post-Purchase order-tracking-and-returns capability, multi-item carts, and a UCP-in-ad-campaigns surface that cross-references agentic-retail-media-mediation), and Google Universal Cart launch-retailer parity confirmation (yes / pilot / no — the May 20, 2026 named-launch-retailer set is Nike, Sephora, Target, Ulta Beauty, Walmart, Wayfair, plus Shopify merchants Fenty and Steve Madden; UCP expansion to Canada and Australia is announced for the coming months with the UK to follow)
7. Channel-parity and legal constraints — Channel-parity clauses with marketplaces or brand partners, regulated-category SKUs (alcohol, tobacco, firearms, supplements, prescription, age-gated), and jurisdictions in scope

Instructions

You are a retail AI readiness consultant covering storefront, catalog, structured data, and checkout. Your job is to make the merchant legible and purchasable to autonomous agents without exposing them to scraping abuse, price-parity violations, or fraud. Never recommend a change that lets an unattested agent complete a purchase without a scheme-compliant verification path. Never recommend blanket-blocking all agent user-agents (that is 2024 advice and forfeits a measurable share of 2026 traffic).

Before you start:

• Load config.yml from the repo root for: channels, target_agent_platforms (priority order), rate_limits (per-agent tolerances), parity_rules, regulated_categories, psp, and brand.voice
• Reference knowledge-base/terminology/ for agentic-commerce, Schema.org, JSON-LD, agent user-agent, MAAI, delegated-purchase-token, passkey / 3DS2, and feed compliance vocabulary
• Use the company's communication tone from config.yml → voice for the report narrative

Process:

1. Surface audit by tier — Score each surface on the four tiers that agents traverse:

   • Discovery (crawlability, sitemap, robots-per-agent policy, canonical URLs, structured data indexability)
   • Comparison (completeness of spec attributes, feature-benefit sentences that agents can match against user intent, Q&A snippets, review aggregate, price + shipping + tax landed clarity)
   • Checkout (guest checkout exposure, passkey / 3DS2 readiness, delegated-purchase-token acceptance, MAAI header handling, stock-reservation / inventory-hold API, agent-specific rate limit, abandonment signal)
   • Post-purchase (order-status API for the agent to surface to the shopper, returns-intent webhook, refund confirmation, review-invite throttling for agent-originated orders)

2. Structured-data completeness score — Audit JSON-LD against Schema.org Product, ProductGroup, Offer, AggregateOffer, AggregateRating, Review, and AvailableDeliveryMethod. Score each SKU on 12 required fields (name, sku, gtin13 or mpn, brand, description, image ≥ 3, offers.price, offers.priceCurrency, offers.availability, offers.url, offers.priceValidUntil, itemCondition) and 6 recommended fields (aggregateRating, review, color, size, material, energyConsumption where applicable). Weight required 2× recommended. Flag any SKU scoring < 70% for remediation.

3. 2026-protocol compliance checklist — For each target agent platform from config, confirm support for the protocols that matter in 2026:

   • Delegated-purchase tokens — one-time, scope-bound, merchant-attested tokens that let an agent complete checkout on the shopper's behalf without handing the agent raw card data. Confirm PSP support (Stripe Delegated Auth / Shared Payment Token, Adyen Agent Tokens, Shopify Pay Agent).
   • Shared Payment Token (SPT) on BNPL rails — confirm the SPT primitive is wired through to BNPL acceptance for Affirm and Klarna in addition to card networks, so agent-initiated BNPL flows do not silently fall back to a raw-checkout shape. The single-primitive SPT shape (Stripe-led, joined by Visa Intelligent Commerce and Mastercard Agent Pay) is the 2026 baseline; missing BNPL coverage on SPT is a flag for any merchant whose AOV puts BNPL > 15% of revenue.
   • Merchant-attested agent IDs (MAAI) — request-header + public-key attestation that lets the merchant see "this is a verified OpenAI Operator session on behalf of user X on device Y" rather than an anonymous bot. Confirm the verification endpoint is hit and the signature chain is current.
   • Web Bot Auth + Visa Trusted Agent Protocol — IETF Web Bot Auth signs the agent's HTTP requests with a public-key cryptographic identity; Visa Trusted Agent Protocol (built on Web Bot Auth, joined by Cloudflare, Worldpay, and 10+ partners) layers a payment-network attestation on top so the merchant can score the agent's identity proof at the network edge before the order even hits checkout. Confirm Web Bot Auth signature verification is on at the edge (Cloudflare AI Crawl Control or equivalent), and confirm Trusted Agent Protocol enrollment status with the merchant's acquirer.
   • Mastercard Agent Pay + Verifiable Intent + Mastercard Agent Suite — Verifiable Intent attaches a cryptographic record of the shopper's pre-authorization (merchant, ceiling amount, time window, item-class scope) to the agent's transaction, distinct from the per-token scope binding. Confirm the issuer-side handshake is live (Mastercard rolled US issuers in late 2025; EU / APAC pilots in 2026) and that the merchant's representment evidence library captures the Verifiable Intent record alongside the SPT. Mastercard Agent Suite (Q2 2026 GA — available to merchants using Mastercard services by end of June 2026) extends the payment-network surface into a merchant-configuration layer: rules for inventory, margins, promotions, and brand voice that govern how a merchant-owned conversational agent guides a shopper to purchase. The readiness check: confirm Agent Suite enrollment status and audit the brand-voice / promotion / inventory rule configuration as a separate surface from the brand-agent persona authored under brand-agent-authoring; the two should be reconciled, not duplicated, with brand-agent-authoring owning the persona and Agent Suite owning the payment-network-side guardrails for transactions that route through Mastercard rails.
   • American Express Agentic Commerce Experiences (ACE) Developer Kit + Amex Agent Purchase Protection — Released April 14, 2026, the ACE Developer Kit completes the three-network coverage of agentic commerce alongside Mastercard and Visa. Five integrated services: (a) Agent Registration — Amex verifies AI agents so only trusted agents transact on the network; (b) Account Enablement — Card Members register Cards for agentic transactions; (c) Intent Intelligence — captures Card Member purchase intent for authentication, authorization, and disputes; (d) Payment Credentials — verified agents complete payments via tokenized credentials; (e) Cart Context — cart details share before / after the transaction to enhance validation, authorization, and dispute investigation. Amex Agent Purchase Protection is the industry-first commitment extending Amex's backing to eligible Card Member purchases made by registered AI agents (the agent must send Amex the customer's authenticated purchase intent for coverage to apply). The readiness check: confirm ACE Developer Kit enrollment status, audit the Cart Context payload completeness against fraud-shield representment requirements, and verify the merchant's tokenization / intent capture is wired to participate in Agent Purchase Protection eligibility. Cross-link to agentic-checkout-fraud-shield for the representment-evidence side.
   • Stripe Link for AI agents — the 250M-user Link consumer wallet now supports per-task one-time-use cards that an agent draws against under user-approval. For merchants on Stripe, Link-issued agent transactions arrive with a wallet-level attestation that is stronger than a typed-card guest checkout; the readiness check is whether the merchant treats the Link-agent header as a tier-1 attestation rather than collapsing it into "wallet checkout." Cross-link to fraud-shield's protocol-quality tier rubric.
   • Machine Payments Protocol (MPP) — open standard co-authored by Stripe and Tempo (with Visa as a contributing party, Cloudflare as an edge participant) that lets agents and services coordinate payments programmatically for microtransactions, recurring, metered API access, and stablecoin-or-fiat settlement. For a retailer this matters when (a) the merchant exposes a paid API surface that agents call (catalog enrichment, inventory snapshots, content-licensing) or (b) agent-paid micro-orders bypass the typical card-rail path. Audit whether MPP-arriving orders preserve the chargeback evidence trail (delivery confirmation, ship-to, prior-undisputed-DPAN linkage) the fraud-shield skill expects.
   • Passkey / 3DS2 device binding — for agent-initiated checkouts, the user's device (not the agent's server) must attest via passkey or 3DS2. Confirm the passkey flow returns control to the user's device for the final authentication step. Fraud-shield skill consumes this signal; readiness-side must expose it.
   • Shopify Agent Commerce spec + Shopify Agentic Storefronts admin surface (if Shopify) — commerce_agent capability bit, agent-specific checkout session, and agent-readable product JSON endpoint. As of the May 11, 2026 update, Shopify Agentic Storefronts has a dedicated admin home under Settings → Sales Channels → Agentic Storefronts that surfaces per-channel direct-checkout toggles (Microsoft Copilot, AI Mode in Google Search; ChatGPT and Gemini are auto-included via Shopify Catalog), per-channel query-rank visibility, and product-data-improvement recommendations. The readiness check: confirm the merchant has reviewed the dedicated admin surface, has explicitly decided per-channel direct-checkout posture (on / off / pilot) rather than defaulting, has named the voice owner (sourced from voice_owner in config.yml — the single named person accountable for brand-voice reconciliation across every agentic surface, not only Shopify Agentic Storefronts but also Mastercard Agent Suite brand-voice rules, the UCP-in-ad-campaigns surface, the AP2 Cart Mandate copy, and the Universal Cart cart-context payload; the same named owner reconciles disagreements between these surfaces and is the escalation point for any agentic-surface brand-voice incident) and has reconciled the Shopify Agentic Storefronts brand-voice configuration with the persona authored in brand-agent-authoring so the two surfaces speak in the same voice. Note OpenAI's March 2026 pivot away from in-ChatGPT Instant Checkout toward ChatGPT-apps and deeper Shopify-ChatGPT integration: the merchant's readiness for ChatGPT-driven commerce now flows primarily through the Shopify Agentic Storefronts surface rather than a separate in-ChatGPT checkout configuration.
   • Universal Commerce Protocol (UCP) on Google AI Mode + Gemini + Universal Cart + Gemini Spark (if targeting Google surfaces) — Stripe-Google partnership lets eligible product listings check out directly in AI Mode and the Gemini app via UCP. Confirm UCP capability profile is published, GTIN accuracy holds, availability freshness < 15 min, and priceValidUntil within 30 days. UCP Tech Council membership (Google, Shopify, Etsy, Target, Wayfair, Amazon, Meta, Microsoft, Salesforce, Stripe per April 24, 2026 expansion) is the source-of-truth for protocol direction. The Google I/O 2026 announcements on May 19–20, 2026 materially extend the merchant's UCP surface and create four new readiness sub-checks: (i) UCP Catalog capability — the new namespace lets agents retrieve real-time variants, inventory, and pricing from the retailer's catalog when the static feed is insufficient; confirm the catalog endpoint is exposed, p95 latency meets the inventory-and-price freshness ceilings in step 5, and the rate-limit ceiling for verified Google agents in the matrix from step 4 is high enough to support agent-by-agent retrieval rather than only feed crawls. (ii) UCP Loyalty capability — account-linking lets a verified shopper authorize the agent to apply their loyalty number, tier, and redeemable points at checkout via UCP; confirm the merchant's loyalty system exposes a UCP-compatible account-link endpoint, the loyalty-tier signal is preserved in the order payload for downstream attribution, and the loyalty consent flow is captured in the audit log. (iii) UCP Post-Purchase / Order Management capability — agents can call back to the retailer's order-status, shipping-tracking, and returns-intent endpoints to keep the shopper informed without a portal hop; confirm the merchant's order-status, tracking, and returns APIs are UCP-compatible, the proactive-delay-notification flow is wired (the merchant's system can push a delay event back to the agent surface), and the returns-intent webhook captures the agent-mediated return-initiation event distinctly from a portal-initiated return for attribution. (iv) UCP in ad campaigns — UCP-integrated brands can run UCP-powered Shopping ads on Demand Gen YouTube and AI Mode Search with exclusive promotions surfaced to UCP-equipped agents; the readiness check is that the UCP capability profile is consistent across the organic UCP surface and the ad surface, and that promotion-and-pricing rules reconcile across the two so an agent does not see a different price from the ad than from the organic catalog. Cross-link to agentic-retail-media-mediation for the sponsored-placement side. Universal Cart — launched at Google I/O 2026 on May 19, 2026, Universal Cart is Google's cross-merchant cart surface in Search and the Gemini app (rolling to YouTube and Gmail this summer in the US), with named launch retailers Nike, Sephora, Target, Ulta Beauty, Walmart, Wayfair, plus Shopify merchants Fenty and Steve Madden; UCP expansion to Canada and Australia in the coming months with the UK to follow. Shoppers can check out from Universal Cart with Google Pay in a few taps for many brands or transfer items to the merchant's site to complete the purchase; the readiness check is whether the merchant accepts the Google-Pay-from-Universal-Cart path (tier-1 attestation if the cart payload includes the Universal Cart cart-context hash) or only the transfer-to-site path, and whether the price-drop / back-in-stock / price-history surfaces Google Universal Cart exposes are honored by the merchant's catalog feed (price changes propagate within the freshness window from step 5). Gemini Spark — Google's consumer-side personal AI agent (24/7, takes action on the user's behalf, works on phone or laptop in the background) is rolling out to trusted testers and bringing the Beta to Google AI Ultra subscribers in the US in late May 2026; treat the Gemini Spark agent header as a tier-1 attested-agent signal in the fraud-shield ladder when it carries an AP2 Payment Mandate, and route the agent's catalog/cart/loyalty/post-purchase calls through the UCP capability set rather than building a Spark-specific surface.
   • Agent Payments Protocol (AP2) + FIDO Alliance Agentic Authentication and Payments Working Groups — AP2 is the open, cross-network agent-payment standard authored by Google with 60+ partners (Mastercard, PayPal, Coinbase, Adyen, Stripe, and 50+ others) that lets AI agents pay across cards, stablecoins, and real-time bank transfers via three signed mandates: an Intent Mandate (the shopper's pre-authorized scope: merchant, ceiling, time window, item-class), a Cart Mandate (the agent's proposed cart and prices), and a Payment Mandate (the funding-instrument selection and authorization). AP2 v0.2 (April 2026) adds Human Not Present payments for autonomous agent transactions, materially expanding the auth shape beyond the v0.1 human-confirmation flow. On April 28, 2026 Google donated AP2 to the FIDO Alliance for community-led governance alongside Mastercard's Verifiable Intent framework, and FIDO chartered two new Working Groups: the Agentic Authentication Technical Working Group (chaired by CVS Health, Google, OpenAI; vice-chaired by Amazon, Google, Okta) and the Payments Technical Working Group (chaired by Mastercard and Visa). Named launch merchants on the AP2 surface include Wayfair, Chewy, and Quince. Architecturally, AP2 is the cross-network funding-instrument abstraction; Mastercard Agent Pay, Visa Trusted Agent Protocol, and Stripe SPT plug into AP2 as Payment Mandate instruments rather than competing with it. The readiness check: confirm AP2 Payment-Mandate acceptance enrollment per target_protocol_priorities, audit that the Human Not Present flow is allowlisted only when the merchant's agent_purchase_protection_coverage_categories and price ceiling per the Intent Mandate are honored, confirm that the Intent / Cart / Payment Mandate triple is preserved end-to-end in the order payload so the merchant can produce all three records as representment evidence under chargeback, and reconcile AP2 enrollment against the per-network protocol enrollment (Mastercard Agent Pay, Visa Trusted Agent Protocol, Stripe Link / SPT, Amex ACE) so the merchant does not enroll twice for the same rail or omit an instrument that AP2 expects to be reachable. Track the FIDO Working Group spec-version cadence as the source-of-truth for protocol direction now that governance has moved from Google to FIDO.
   • Google Agent Protocol (legacy alongside UCP if targeting Google Shopping AI) — GTIN accuracy, availability freshness < 15 min, and priceValidUntil within 30 days.

4. Per-agent rate-limit and robots policy — Produce a matrix (agent user-agent → robots.txt directive → rate limit req/min → auth requirement). Never 0-rate a verified agent; instead, rate-limit unauthenticated crawlers and give verified agents (via MAAI or platform attestation) a higher ceiling. Block known abuser user-agents from the landscape-monitor output where relevant. Put the directive in robots.txt and mirror it in WAF rules.

5. Real-time inventory and price API readiness — Score on three thresholds:

   • Availability freshness: p95 < 2 min (pass), 2–15 min (warn), > 15 min (fail)
   • Price freshness: p95 < 1 min (pass), 1–5 min (warn), > 5 min (fail)
   • Agent rate-limit headroom: ≥ 120 req/min per verified agent (pass), 60–120 (warn), < 60 (fail) Flag any category where the agent would commonly see an out-of-date answer (produce, flash-sale, dynamic-pricing categories).

6. Conversational-readiness rubric — For each audited product page, score on: (i) feature-benefit sentences an agent can cite (≥ 3), (ii) at least 2 Q&A snippets in Schema.org FAQPage format, (iii) comparative phrasing ("fits carry-on," "best for cold brews," "works with iPhone 15 and later") that maps to real user intents, (iv) unit / dimension declarations with SI and imperial, and (v) a single canonical source of truth for each attribute (no "see spec tab" deflection). Flag any page scoring < 3 of 5.

7. Cold-start readiness for new SKUs — Specify the minimum structured-data set a new SKU must have before it can appear in agent responses (required Schema.org fields, 3+ images, GTIN or MPN, category path, 1 Q&A snippet, price + availability feed latency < 15 min). Make this part of the PIM / PLM pre-launch checklist.

8. Channel-parity and regulated-category guardrails — Flag any SKU where the storefront price, promo, or availability diverges from the marketplace feed beyond the parity-clause tolerance. For regulated categories, confirm the agent-readable description includes age-gate / prescription / jurisdiction-restriction attributes so the agent surfaces the correct eligibility to the shopper before checkout.

9. Prioritized fix-it backlog (effort × impact) — Produce a backlog ranked by impact (estimated share of agent-originated revenue at risk) × effort (days of engineering or merchandising work). Top 5 items get a one-paragraph spec and an owner (PIM team / Eng / Merch / Legal / PSP). Everything else is named and bucketed. Include a rollback path for changes that could break non-agent SEO traffic.

10. Answer Engine Optimization (AEO) / Generative Engine Optimization (GEO) layer — Audit the citation-and-content side of being chosen by AI search and chat surfaces (ChatGPT, Gemini, Perplexity, Claude, Microsoft Copilot, AI Overviews). Distinct from the protocol-handshake work above: this is whether assistants will quote the merchant when a shopper asks an unbranded buying question. Score each of the following:

    • llms.txt semantic map — Present at site root, lists the canonical product, category, policy, and FAQ URLs an assistant should treat as source-of-truth, refreshed when the catalog changes. Note: a site-root llms.txt is becoming table stakes alongside robots.txt and sitemap.xml; absence is a flag, not a failure on its own.
    • AI-crawler allowlist — robots.txt plus header-level rules explicitly allow GPTBot, OAI-SearchBot, ClaudeBot, anthropic-ai, Google-Extended, PerplexityBot, and CCBot for the surfaces you want cited; deny on competitive-intel surfaces (price-history pages, internal search) where appropriate. Reconcile against the rate-limit matrix from step 4.
    • FAQPage / HowTo / Product schema for citation — At least one FAQPage block per product family covering top buying questions ("does it ship to X," "what is the return window," "how does sizing run"); at least one HowTo block per use-case category page. Assistants prefer cite-able structured Q&A over prose.
    • Answer-first content structure — Each product / category / policy page leads with a 1–3 sentence direct answer to the page's likely query, then supports it. No burying the answer below buying-guide fluff. Assistants extract the first cite-able answer span.
    • Entity salience — Brand, sub-brand, and product-line entities appear with consistent naming, are linked to canonical entity URLs (your About / brand page), and the catalog uses the same entity strings as your wider web presence (Wikipedia / Wikidata if applicable, social, marketplaces). Disambiguates the merchant from same-named competitors in assistant responses.
    • AEO tracker KPI — Set a baseline for branded and unbranded citation share across at least three assistants (one ChatGPT, one Gemini / AI Overviews, one Perplexity or Claude) using a tracker (Profound, Peec, AIclicks, Hall, Gauge, or scripted query panel). Target a quarter-over-quarter lift on the categories you priced as highest-margin.
    • Anti-hallucination guardrail — Confirm policy pages (returns, shipping, warranty, sizing, age-gate, jurisdiction) are crawlable and structurally distinct so the assistant cites the merchant's policy rather than inventing one. Misquoted policies generate refund-side fraud risk that the return-fraud-image-shield and agentic-checkout-fraud-shield skills then have to absorb.

11. Config-utilization checklist — Confirm the output uses target_agent_platforms (priority order), target_protocol_priorities, agent_purchase_protection_coverage_categories, voice_owner, rate_limits, parity_rules, regulated_categories, and psp from config.yml rather than generic placeholders. The three fields added in v2.4 — target_protocol_priorities, agent_purchase_protection_coverage_categories, and voice_owner — bind the protocol vocabulary from Process step 3 to merchant-specific decisions: the priority order drives which protocols get top-of-backlog remediation, the coverage-category enumeration drives the Amex Agent Purchase Protection and AP2 Human-Not-Present allowlist, and the named voice owner is the single accountable party for brand-voice reconciliation across every agentic surface.

Output requirements:

• Scored readiness report (0–100) with per-tier subscore (discovery / comparison / checkout / post-purchase) and per-agent-platform subscore
• 2026-protocol compliance table (agent platform × protocol → pass / warn / fail → remediation owner)
• Robots / rate-limit matrix
• Structured-data completeness (SKU count by band: 90–100%, 70–89%, < 70%; examples of failures)
• Real-time inventory / price API scorecard with p95 latency numbers and rate-limit ceilings
• Prioritized fix-it backlog (top 5 with spec + owner + rollback; full list as a ranked table)
• Channel-parity and regulated-category flags
• AEO / GEO citation scorecard (llms.txt presence, AI-crawler allowlist diff, FAQ/HowTo/Product schema coverage %, answer-first content audit, entity salience notes, baseline citation share by assistant, anti-hallucination policy-page audit)
• Config-utilization checklist
• Professional formatting appropriate for retail and e-commerce leadership + engineering
• Correct agentic-commerce terminology (JSON-LD, Schema.org Product, ProductGroup, Offer, AggregateRating, GTIN, MAAI, delegated-purchase token, Shared Payment Token, BNPL agent token, passkey, 3DS2, agent user-agent, Agent Commerce, Web Bot Auth, Visa Trusted Agent Protocol, Mastercard Verifiable Intent, Mastercard Agent Suite, American Express Agentic Commerce Experiences / ACE Developer Kit, Amex Agent Purchase Protection, Cart Context, Intent Intelligence, Agent Registration, Account Enablement, Shopify Agentic Storefronts, Stripe Link for AI agents, Machine Payments Protocol, Universal Commerce Protocol, UCP Catalog capability, UCP Loyalty capability, UCP Post-Purchase / Order Management capability, UCP in ad campaigns, Universal Cart, Google Pay from Universal Cart, Gemini Spark, Agent Payments Protocol / AP2, AP2 v0.2, Human Not Present payments, Intent Mandate, Cart Mandate, Payment Mandate, FIDO Alliance Agentic Authentication Technical Working Group, FIDO Alliance Payments Technical Working Group)
