Use when debugging what crawlers or bots see on a deco site, verifying if SSR is active for bots, or diagnosing firstByteThresholdMS behavior.
Use when a site's SEO metadata (title, og:tags, LD+JSON) is missing, incomplete, or handled by a weak custom component. Covers configuring the apps SEO sections for general pages, PDPs, and PLPs via the deco admin.
Configure deco.cx Variants — the mechanism that swaps the value of a section, page, image, message, or ANY custom-typed prop based on a matcher rule (device, cookie, date, A/B test, geo, path, query string, etc.). Use when the user asks to A/B test a section, personalize a page per audience/segment, show different banners per device or location, schedule a promotion by date/cron, add a new variant-able type (promotion, VTEX segment, product list, menu items), write a custom matcher, or generally wire up `website/flags/multivariate*` in `.deco/blocks/*.json`. Covers the JSON shape (`variants: [{ value, rule }]`), the resolution order (first match wins, catch-all last), every built-in matcher (`always`, `never`, `device`, `date`, `cron`, `random`, `cookie`, `host`, `pathname`, `queryString`, `userAgent`, `location`, `site`, `environment`, `multi`, `negate`), how to compose them with `multi` (and/or) and `negate`, the 8-line boilerplate to create your own `flags/multivariate/<type>.ts`, the shape of a custom `ma
Install and configure the Blog Manager on a deco-site storefront. Covers the blog app, page routes, sections, Blog Manager MCP connection in Studio, and first-run brand context initialization.
Use when inside a deco.cx ecommerce repository (deco.ts present, decobot in PR history) and the user wants automated QA for purchase-journey correctness — set up E2E coverage, test the add-to-cart / checkout flow, or scaffold a CI gate for the store with the @decocms/qa engine. NOT for load/cache performance testing (use deco-e2e-testing) or hand-written Playwright spec files.
Quick fixes for common, isolated issues in deco.cx storefronts. Use when the user reports a specific symptom that doesn't warrant a full skill. This is a growing knowledge base — add new entries as they're discovered.

Headless login on VTEX refers to authenticating users outside the VTEX Admin panel — in custom storefronts, external applications, or development environments that consume VTEX APIs with an authenticated session.
Headless login only works for domains explicitly authorized in the VTEX account settings.
In the VTEX Admin panel, navigate to:
Account Settings → Account → Stores → (select store) → Edit → Add Host
Add the domain (e.g. my-store.com, localhost:3000) to the list of allowed hosts. Without this entry, VTEX will block all headless authentication attempts from that origin.
When it is not practical to run a full login flow in a test environment, you can copy authentication cookies from an already-authenticated session.
VtexIdclientAutCookie
document.cookie).| Name | Description |
|---|---|
VtexIdclientAutCookie | Main session authentication cookie |
VtexIdclientAutCookie_<accountName> | Per-account variant (present in multi-store setups) |
Note: these cookies expire. If the authenticated state does not persist, check whether the cookies are still valid at the source.
| Symptom | Likely cause |
|---|---|
| Login keeps redirecting in a loop | Domain is not in the authorized hosts list |
| Copied cookie does not maintain session | Cookie is expired, or the destination domain is not authorized |
API returns 401 even with cookie present | Account name in the cookie does not match the environment |
