Each is written by the company that owns the API, which is why they encode the retry, idempotency, and signature-verification details generic integration advice leaves out. ## Verified on Cursor (11) ### 1. stripe-best-practices — score 59/100 (verified-org) Stripe's own integration playbook: pick the right API, set up Connect and billing, and handle keys and webhooks securely. - Best for: Building, modifying, or reviewing any Stripe integration — payments, marketplaces, subscriptions, secure key management. - Not ideal for: Non-Stripe payment processors (Adyen, Braintree, PayPal) — the rules are Stripe-specific. - Publisher: Stripe · MIT - Verified on: claude-code, cursor, gemini-cli ```bash /plugin marketplace add stripe/ai ``` Full entry: https://top-agent-skills.com/skill/stripe-best-practices (https://top-agent-skills.com/skill/stripe-best-practices.md) ### 2. stripe-projects — score 59/100 (verified-org) Provision a Postgres, Redis, auth, or LLM provider through the Stripe Projects catalog rather than signing up by hand. - Best for: Letting an agent provision and wire up cloud services (DB, cache, auth, email, model providers) with credentials returned inline. - Not ideal for: Teams that must provision through their own IaC (Terraform, Pulumi) or a locked-down cloud account. - Publisher: Stripe · MIT - Verified on: claude-code, cursor, gemini-cli ```bash /plugin marketplace add stripe/ai ``` Full entry: https://top-agent-skills.com/skill/stripe-projects (https://top-agent-skills.com/skill/stripe-projects.md) ### 3. resend — score 59/100 (verified-org) Resend's own API skill: send transactional and batch email, handle inbound webhooks, and manage domains, templates, and keys. - Best for: Wiring Resend into an app — transactional sends, batch sends, inbound webhook handling, and domain/template/key management. - Not ideal for: Non-Resend providers (SendGrid, Postmark, SES) — the SDK calls and webhook signatures are Resend-specific. - Publisher: Resend · MIT - Verified on: claude-code, cursor, codex ```bash npx skills add resend/resend-skills ``` Full entry: https://top-agent-skills.com/skill/resend-email (https://top-agent-skills.com/skill/resend-email.md) ### 4. stripe-directory — score 57/100 (verified-org) Find vendors and partners for a job-to-be-done — and, where supported, let the agent purchase and consume the service. - Best for: Discovering software, service providers, or partners for a vertical or workflow, with optional agent-initiated purchase. - Not ideal for: Internal vendor catalogs or procurement that must route through an approved supplier list. - Publisher: Stripe · MIT - Verified on: claude-code, cursor, gemini-cli ```bash /plugin marketplace add stripe/ai ``` Full entry: https://top-agent-skills.com/skill/stripe-directory (https://top-agent-skills.com/skill/stripe-directory.md) ### 5. webhook-skills — score 56/100 (verified-org) Hookdeck's webhook playbook: 40 provider-specific skills covering signature verification, idempotency, and event handling — each with runnable examples. - Best for: Building a webhook receiver for a specific provider with correct signature verification, idempotency, and retry handling — the part most teams get subtly wrong. - Not ideal for: Outbound API consumption or OAuth flows — this is receiver-side webhook handling, not a general REST client. - Publisher: Hookdeck · MIT - Verified on: claude-code, cursor ```bash npx skills add github.com/hookdeck/webhook-skills --skill stripe-webhooks ``` Full entry: https://top-agent-skills.com/skill/hookdeck-webhook-skills (https://top-agent-skills.com/skill/hookdeck-webhook-skills.md) ### 6. composio — score 54/100 (verified-org) Composio's official skill for connecting agents to 1000+ external apps: auth configs, per-user connections, tool execution, and triggers.

APIs, data, boundaries, scale. Full entry: https://top-agent-skills.com/skill/system-design (https://top-agent-skills.com/skill/system-design.md) ## In APIs & Integrations but NOT verified on Cursor (11) These may well work — the SKILL.md format is shared. They are listed as unverified because this site lists an agent only where the install was run or the publisher documents a path for it. - block-kit — Slack's own Block Kit skill — and the rare vendor skill that needs no token, because it validates against Slack's public API. (https://top-agent-skills.com/skill/slack-block-kit) - connect-recommend — The marketplace architecture decision, made with a compatibility matrix that blocks invalid Connect configurations instead of describing them. (https://top-agent-skills.com/skill/stripe-connect-recommend) - hubspot-agent-skills — First-party HubSpot CRM operations for agents: lookups, deals, quote-to-cash, reporting.

(https://top-agent-skills.com/skill/gtm-eng-skills) ## Common question **Why prefer a vendor skill over asking Cursor directly about an API?** Because API surfaces move and training data does not. A vendor-maintained skill is updated when the API changes and states the current recommended pattern — which SDK, which auth flow, which webhook signature scheme. Asking the model cold gets you the most common pattern on the internet, which is often two API versions old. --- _Top Agent Skills.
