[Get the skills plugin](https://storeconnect.com/ai#SC-ContentBlock-ai-providers) or [watch the full demo](https://storeconnect.com/ai#SC-ContentBlock-ai-full-demo). ## Every tenth of a second is measurable revenue Speed isn't a technical nicety. Deloitte and Google's Milliseconds Make Millions study found a 0.1 second improvement in mobile site speed increased retail conversions by 8.4% and average order value by 9.2%[^1]. A page that's a full second slower than it should be is leaving real money on the table every day. The skill teaches the agent to instrument before it changes anything, using StoreConnect's web Console and debug and timer tags, then to match each measured cost to the right fix: collection and pagination cost, per-item hot paths, asset weight or client-side batching[^2]. ## Blank, wrong and slow look alike but have different causes A template that renders blank, one that renders the wrong thing and one that renders slowly can look like the same bug. They aren't, and fixing the wrong one wastes the afternoon. Stack Overflow's 2025 survey found 45% of developers say debugging AI-generated code is more time-consuming[^3], and an agent that treats every symptom the same way adds to that pile. The skill separates the three and gives the agent a diagnosis path for each, including drop and record introspection to see what data a template actually has. ## A badly keyed cache can show one customer's content to another Caching makes pages fast, and a poorly designed cache key can serve the wrong content to the wrong visitor. That's not just a bug. It can be a privacy incident. IBM's 2025 research puts the global average cost of a data breach at $4.44 million[^4]. The skill covers cache key design and invalidation, so cached fragments stay correct and never reach the wrong visitor[^2]. For an audit that changes nothing, the agent is pointed to the separate theme review skill instead. ## Fix the real cause the first time Guessing at performance problems is slow, and sometimes dangerous. [Get the skills plugin](https://storeconnect.com/ai#SC-ContentBlock-ai-providers). The debugging and performance skill installs with the full StoreConnect catalog for your AI tool. Load it before adding any debug, timer or cache tag, and whenever a page is slow, blank or showing stale content. [Watch the full demo](https://storeconnect.com/ai#SC-ContentBlock-ai-full-demo). CEO Mikel Lindsaar shows how an agent works on a live store, with every change staged and approved before it reaches customers. ## References [^1]: [Deloitte Digital and Google, "Milliseconds Make Millions."](https://www2.deloitte.com/content/dam/Deloitte/ie/Documents/Consulting/Milliseconds_Make_Millions_report.pdf){:target="_blank"} [^2]: [StoreConnect, "StoreConnect AI" GitHub repository (README, skills and provider packages).](https://github.com/GetStoreConnect/ai){:target="_blank"} [^3]: [Stack Overflow, "2025 Developer Survey: AI."](https://survey.stackoverflow.co/2025/ai){:target="_blank"} [^4]: [IBM, "Cost of a Data Breach Report 2025" newsroom release (research conducted by Ponemon Institute).](https://newsroom.ibm.com/2025-07-30-ibm-report-13-of-organizations-reported-breaches-of-ai-models-or-applications,-97-of-which-reported-lacking-proper-ai-access-controls){:target="_blank"} --- ## Follow StoreConnect - [Email Newsletter](https://storeconnect.com/c/lp-newsletter) - [LinkedIn Newsletter](https://www.linkedin.com/build-relation/newsletter-follow?entityUrn=7444956928444862464) - [YouTube](https://www.youtube.com/channel/UCngKdP2x8l1wcbAKW3tvU8g) - [LinkedIn](https://www.linkedin.com/company/storeconnect) - [X / Twitter](https://x.com/storeconnecthq) ## Popular Links - [Partners](https://storeconnect.com/partners) - [Become a Partner](https://storeconnect.com/become-a-partner) - [News](https://storeconnect.com/articles/news) - [Events](https://storeconnect.com/articles/events) - [Live Events](https://storeconnect.com/live-events) - [Feature Comparison](https://storeconnect.com/how-we-compare) - [Download a free trial](https://appexchange.salesforce.com/appxListingDetail?listingId=a0N3A00000FMkeKUAT) - [Book a Demo](https://storeconnect.com/contact) ## Documentation - [Help documentation](https://support.storeconnect.com/help-documentation) - [Videos & tutorials](https://support.storeconnect.com/videos-tutorials) - [Developer reference](https://support.storeconnect.com/developer-reference) - [Release notes](https://support.storeconnect.com/release-notes) - [Troubleshooting](https://support.storeconnect.com/troubleshooting) - [Trust Center](https://trust.getstoreconnect.com/) - [Status Page](https://status.storeconnect.com/) ## Contact - info@getstoreconnect.com - US +1 415 745 3230 - AUS +61 2 8365 2308 100 S Ashley Dr, Suite 600-2461 Tampa FL 33602-600 USA Level 22, Sydney Place 180 George Street Sydney, NSW, 2000, AUS ## Machine-readable - [Site index for agents](https://storeconnect.com/llms.txt): curated map of this site in llms.txt format - [Documentation index for agents](https://support.storeconnect.com/llms.txt): full technical and product documentation map Every page and article on this site has a Markdown rendering: append `.md` to its URL.
