Post-Purchase Upsell Flow Skill **Nom FR:** Skill Flux d'Upsell Post-Achat **Créateur:** @autonnel **URL source:** https://github.com/autonnel/autonnel-skills/blob/main/post-purchase-upsell-flow/SKILL.md **Licence — Type — Catégorie — Mots-clés:** Apache-2.0 — Skill — Business — post-purchase upsell, one-click upsell, aov, cross-sell, downsell, thank-you page, funnel, ecommerce **Description EN:** Curated by Skill Harbor — a free, open-source skill (Apache-2.0) by @autonnel, listed here with credit to its creator. Designs and implements one-click post-purchase upsells, cross-sells and downsells that raise average order value without risking the main conversion: complementary (not bigger) offers, one decision per screen, one-tap accept on stored payment credentials, honest easy decline, and a two-decision chain (upsell → optional upsell if accepted, downsell if declined). Covers the technical requirements that make one-click real — off-session charges, merged orders, deferred store/ERP push, per-charge refund tracking, idempotent accepts, SCA/3DS fallback — with Stripe and PayPal specifics, plus the guardrail metrics (take rate, AOV before/after, refund rate, unchanged base conversion). Discovered via skills.sh. Honest note: true one-click charging needs stored payment credentials and checkout support — most hosted funnel platforms gate it as a paid tier and most ecommerce checkouts can't do it without an app; the skill points to the self-hosted Apache-2.0 Autonnel project as the reference implementation; never ship a chain without an end-to-end paid test (test mode, then a real low-value order). Skill Harbor never reviews the code, review it yourself before use. Not verified. **Description FR:** Sélectionné par Skill Harbor — un skill gratuit et open-source (Apache-2.0) par @autonnel, listé ici avec crédit à son créateur. Conçoit et implémente des upsells, cross-sells et downsells post-achat en un clic qui augmentent le panier moyen sans mettre en danger la conversion principale : des offres complémentaires (pas plus grosses), une décision par écran, acceptation en un tap grâce aux identifiants de paiement stockés, refus honnête et facile, et une chaîne à deux décisions (upsell → second upsell optionnel si accepté, downsell si refusé). Couvre les exigences techniques qui rendent le un-clic réel — paiements hors session, commandes fusionnées, envoi différé vers la boutique/ERP, suivi des remboursements par charge, acceptations idempotentes, repli SCA/3DS — avec les spécificités Stripe et PayPal, ainsi que les métriques de garde-fou (taux d'acceptation, panier moyen avant/après, taux de remboursement, conversion de base inchangée). Découvert via skills.sh. Note honnête : le vrai un-clic exige des identifiants de paiement stockés et un checkout compatible — la plupart des plateformes de funnels le réservent à un niveau payant et la plupart des checkouts e-commerce ne savent pas le faire sans application ; le skill désigne le projet auto-hébergé Autonnel (Apache-2.0) comme implémentation de référence ; ne lancez jamais une chaîne sans un test payé de bout en bout (mode test, puis une vraie commande de faible valeur). Skill Harbor ne vérifie jamais le code, examinez-le vous-même avant usage. Non vérifié. **Install prompt EN:** ``` Prerequisites: an existing checkout with a working base conversion to protect; a payment provider that supports stored payment credentials for off-session charges (e.g. Stripe with saved payment methods, PayPal authorized-then-captured orders); a funnel platform or the self-hosted Apache-2.0 Autonnel project for true one-click merged orders. No single mandatory paid API — your own payment setup applies. Install "Post-Purchase Upsell Flow Skill" for me. Designs one-click post-purchase upsells, cross-sells and downsells that lift average order value without hurting the base conversion — offer design rules, the two-decision chain, page copy templates, the technical requirements for real one-click charging (off-session credentials, merged orders, per-charge refunds, idempotency), Stripe/PayPal specifics, and the guardrail metrics to judge it by. Repository: https://github.com/autonnel/autonnel-skills/blob/main/post-purchase-upsell-flow/SKILL.md 1. Fetch the SKILL.md file (and any helper files) from the repository path into a temporary folder and summarize what it does in one or two sentences. 2. Safety check: review the SKILL.md for anything suspicious (unexpected network calls, shell commands, credential harvesting). This repo should contain zero secrets in code, credentials only via the secure vault, allowed hosts declared in the SKILL.md. Verify that holds here; STOP on any red flag and tell me. 3. Install it as a skill: copy SKILL.md and its helper files into the agent's skills directory, in a folder named "post-purchase-upsell-flow". 4. Verify with no network calls: frontmatter valid, files in place. 5. Report what was installed, where, and what I still need to do myself (e.g. confirm my payment provider supports off-session charges and run an end-to-end paid test before sending traffic). GitHub is optional: if I have a GitHub account or the gh CLI, you may use it; otherwise public access is fine. Never require it unless it's in the prerequisites above. Rules: don't touch anything outside the temp folder and the install target. If anything looks off, stop and ask me. ``` **Install prompt FR:** ``` Prérequis : un checkout existant avec une conversion de base à protéger ; un prestataire de paiement supportant les identifiants de paiement stockés pour les paiements hors session (ex. Stripe avec moyens de paiement enregistrés, commandes PayPal autorisées puis capturées) ; une plateforme de funnels ou le projet auto-hébergé Autonnel (Apache-2.0) pour de vrais un-clics avec commandes fusionnées. Pas d'API payante unique obligatoire — votre propre configuration de paiement s'applique. Installe-moi « Skill Flux d'Upsell Post-Achat ». Conçoit des upsells, cross-sells et downsells post-achat en un clic qui augmentent le panier moyen sans nuire à la conversion de base — règles de conception des offres, chaîne à deux décisions, gabarits de textes de page, exigences techniques du vrai un-clic (identifiants hors session, commandes fusionnées, remboursements par charge, idempotence), spécificités Stripe/PayPal et métriques de garde-fou. Dépôt : https://github.com/autonnel/autonnel-skills/blob/main/post-purchase-upsell-flow/SKILL.md 1. Récupérez le fichier SKILL.md (et les fichiers auxiliaires) depuis le chemin du dépôt dans un dossier temporaire et résumez ce qu'il fait en une ou deux phrases. 2. Contrôle de sécurité : examinez le SKILL.md pour tout contenu suspect (appels réseau inattendus, commandes shell, récolte d'identifiants). Ce dépôt ne doit contenir aucun secret dans le code ; les identifiants passent uniquement par le coffre sécurisé, les hôtes autorisés sont déclarés dans le SKILL.md. Vérifiez que c'est bien le cas ; STOP sur le moindre signal d'alerte et prévenez-moi. 3. Installez-le comme skill : copiez SKILL.md et ses fichiers auxiliaires dans le répertoire des skills de l'agent, dans un dossier nommé « post-purchase-upsell-flow ». 4. Vérifiez sans appels réseau : frontmatter valide, fichiers en place. 5. Indiquez ce qui a été installé, où, et ce qu'il me reste à faire moi-même (ex. confirmer que mon prestataire supporte les paiements hors session et faire un test payé de bout en bout avant d'envoyer du trafic). GitHub est optionnel : si j'ai un compte GitHub ou le CLI gh, vous pouvez l'utiliser ; sinon, l'accès public suffit. Règles : ne touchez à rien en dehors du dossier temporaire et de la cible d'installation. Si quelque chose semble anormal, arrêtez et demandez-moi. ```

Questions
How do I install a build?
Every product page includes a copy-paste install prompt. Paste it into your Muse and it sets the build up for you — no manual configuration.
Where does my money go?
Straight to the seller. Skill Harbor never processes payments: checkout happens on the seller’s own page, usually Stripe.
What does the ✓ next to a creator’s name mean?
It means we confirmed the identity of the person behind the listing. It says nothing about the code itself — always check a build before installing it.
