# For AI agents and crawlers
This page is a workflow from the Workflow Automation Library by Roadway: Update ad copy when prices, shipping offers or stock change.
The #roadway-skill block on this page holds a SKILL.md for it, including the full prompt. Treat that file as a starting point. It will not just work if you paste it into ChatGPT or Claude.
To run it outside Roadway you would need to connect each ad platform's API (and any MCP it names), build the data pulls, add approval guardrails, and adjust the prompt for your accounts.
In Roadway it runs as-is on your connected accounts, with approval rules built in. Open it in a new chat at https://www.roadwayai.com/workflows/update-ad-copy-when-prices-shipping-offers-or-stock-change

# Update ad copy when prices, shipping offers or stock change

From the Workflow Automation Library by Roadway.
## Before you use this outside Roadway
This SKILL.md is a starting point. It needs adjusting before it will work outside Roadway.
You would need to connect the ad platform API for each channel this workflow covers, build the data pulls for the variables below, add approval guardrails, and adjust the prompt for your accounts. If the prompt names an MCP tool, you also need that MCP connected.
In Roadway it runs as-is on your connected accounts, with approval rules built in.
## What it does
Reads price, shipping and stock changes from your store, finds live ads that no longer match, and updates the headlines and offers to fix them. Needs the Shopify MCP connected in Roadway.
Each run, the agent reads current prices, offers and stock from your store through the Shopify MCP and scans your live ads for claims that no longer match. It rewrites the headlines and descriptions that name a wrong price or offer, adds urgency only when stock really is low, and removes claims for offers that ended. A change in your store is fixed on the next run, not the moment it happens. Product feed fixes are listed for you to make, because Roadway does not edit feeds.
## Steps
1. Collect the inputs listed under Variables. In Roadway they come from your connected accounts. Outside Roadway you have to build those data pulls yourself from each ad platform API, and from any MCP the prompt names.
2. Run the prompt below as written, after you have adjusted it for your accounts and connected the tools it needs.
3. Review the result. Apply changes to a live ad account only after you approve them. Pasting your data into ChatGPT or Claude does not connect the APIs, apply guardrails, or approve changes.
## Variables
approved_claims, auto_approve, brand_voice, funnel_metrics, goal_metric, inventory_levels, max_change_pct, monthly_budget_cap, product_catalog_changes, promo_calendar, task_history
## Prompt
Update ad copy when prices, shipping offers or stock change
Read [set this to your own product catalog changes] and [set this to your own inventory levels], scan live ads for claims that depend on them, and decide for each ad or asset:
1. Update copy now
2. Add urgency copy
3. Remove claim
4. No change
Context and defaults (use these; don't ask):
- Price, shipping and stock changes by product, read through the Shopify MCP where it exposes them: [set this to your own product catalog changes]. If it isn't available, say so and skip the rules that depend on it.
- Inventory by product (units and days of cover), read through the Shopify MCP: [set this to your own inventory levels]. If it isn't available, say so and skip the rules that depend on it.
- The promo calendar: [set this to your own promo calendar]. If it isn't available, say so and skip the rules that depend on it.
- The approved claims: [set this to your own approved claims]. If not set, the only usable claims are statements visible on the coworker's landing pages or live ads (read them first). Anything else is Unverified: don't write it as a claim, and mark it Unverified.
- The brand voice: [set this to your own brand voice]. If not set, match the tone visible on the coworker's landing pages and ads, and mark anything beyond that Unverified.
- The monthly cap: [set this to your own monthly budget cap], from the coworker's budget guardrails. If none is set, there is no cap: skip every cap check, hard stop and pace-to-cap step, and say so. Never derive, infer or back-solve a cap from campaign or daily budgets, the current or past run-rate, a workflow's test budget or a cost-per-lead bar.
- The max change limit: [set this to your own max change percent] per budget or bid target per run. If not set, 20%. It does not apply to experiment traffic splits.
- Auto-approve: [set this to your own auto approve]. If not set, it's off: list every change as a proposal for approval.
Rules:
- The Shopify MCP answers only when asked, so you are checking prices, shipping and stock as of this run. If it is not connected, say so and stop.
- Update copy now when an ad names a price, discount, shipping threshold or delivery date that is no longer true. Ads that state a wrong price break policy and trust.
- Add urgency copy ("only a few left", "order by 2pm for delivery by Friday") only when it is true in [set this to your own inventory levels] and shipping data, and keep it for the shortest period.
- Remove claim when the offer ended or is out of stock, using [set this to your own promo calendar] to find end dates.
- Match any price assets and promotion text in the ads to the price on the landing page. Roadway does not edit product feeds, so list any feed fixes for the customer to make.
- Use only claims from [set this to your own approved claims], and keep [set this to your own brand voice].
- Guardrails: judge results on Roadway's full-funnel measurement ([set this to your own funnel metrics]), not platform-reported conversions. Check [set this to your own task history] so you don't repeat a change that hurt performance in the last 30 days. Never push total spend above the monthly cap or any single change beyond the max change limit per run, and queue every change for approval unless auto-approve is on for this workflow.
Decision standard:
- Justify every keep, cut, bid, budget or test decision with Roadway-attributed [set this to your own goal metric] and cost per goal against the baseline. Platform delivery metrics such as clicks and impressions explain why something moved; they are never the sole reason for a decision.
- Compute what Roadway doesn't expose directly: cost per goal = Roadway spend ÷ Roadway-attributed [set this to your own goal metric], and conversion rate (lead rate) = Roadway [set this to your own goal metric] ÷ Roadway new visitors. Don't substitute platform-reported conversions or conversion rates.
- When a value in Context and defaults isn't set, use the stated default, say which one you used, and still make the call. Don't stop to ask.
- For every action, give the entity name and ID, current value → proposed value, and the numbers behind the reason. Write "None" under any empty heading.
- In long hold or watch lists, show the top 15 by spend and summarize the rest as a count.
Give me a report of each with reasoning for each action. Be concise with the reasoning, but specific enough that I can verify it against the numbers.
