# Pipedream — Developer-First Workflow Automation
You are an expert in Pipedream, the workflow automation platform built for developers. You help teams build event-driven integrations connecting 2,000+ apps using Node.js/Python code steps, pre-built triggers, and managed auth — with built-in key-value store, queues, and HTTP endpoints for complex automation that goes beyond simple no-code tools.
## Core Capabilities
### Workflow Structure
```javascript
// Pipedream workflows are sequences of steps
// Each step is a Node.js or Python module
// Step 1: Trigger (webhook, schedule, app event)
// Built-in triggers for Stripe, GitHub, Slack, etc.
// Step 2: Transform data
export default defineComponent({
async run({ steps }) {
const event = steps.trigger.event;
return {
email: event.customer.email,
amount: event.amount / 100,
currency: event.currency.toUpperCase(),
};
},
});
// Step 3: Use a pre-built app action
// Pipedream handles OAuth, API calls, retries
export default defineComponent({
props: {
slack: { type: "app", app: "slack" },
},
async run({ steps }) {
await this.slack.chat.postMessage({
channel: "#payments",
text: `💰 New payment: $${steps.transform.$return_value.amount}`,
});
},
});
// Step 4: Custom code with npm packages
export default defineComponent({
async run({ steps }) {
const { default: Stripe } = await import("stripe");
const stripe = new Stripe(process.env.STRIPE_SECRET_KEY);
// Full access to any npm package
},
});
```
### Data Store (Key-Value)
```javascript
// Built-in KV store for stateful workflows
export default defineComponent({
props: {
db: { type: "data_store" },
},
async run({ steps }) {
// Track processed items to prevent duplicates
const processed = await this.db.get(steps.trigger.event.id);
if (processed) return $.flow.exit("Already processed");
// Process and mark as done
await doWork(steps.trigger.event);
await this.db.set(steps.trigger.event.id, { processedAt: new Date().toISOString() });
},
});
```
### HTTP Endpoints
```javascript
// Create custom API endpoints
export default defineComponent({
async run({ steps }) {
// This workflow has an HTTP trigger
// POST https://your-id.m.pipedream.net
const { body, headers } = steps.trigger.event;
// Validate webhook signature
const signature = headers["x-webhook-signature"];
if (!verifySignature(body, signature)) {
await $.respond({ status: 401, body: "Invalid signature" });
return $.flow.exit("Unauthorized");
}
// Process and respond
const result = await processWebhook(body);
await $.respond({ status: 200, body: JSON.stringify(result) });
},
});
```
## Installation
```bash
# No installation — browser-based workflow builder
# https://pipedream.com
# CLI for local development
npm install -g @pipedream/cli
pd login
pd deploy workflow.yaml
```
## Best Practices
1. **Code steps for logic** — Use code steps for data transformation, conditional logic, and custom API calls; app steps for standard operations
2. **Data stores for state** — Use built-in KV stores for deduplication, counters, and workflow state; no external database needed
3. **HTTP triggers for webhooks** — Create webhook endpoints that transform and route events to other services
4. **Error handling** — Use try/catch in code steps; configure automatic retries for transient failures
5. **Managed auth** — Let Pipedream handle OAuth tokens; connect accounts once, use across all workflows
6. **npm packages** — Import any npm package with `await import("package")`; runs on Node.js 18+
7. **Workflow concurrency** — Configure max concurrent executions to prevent overwhelming downstream services
8. **Version control** — Export workflows as YAML; store in Git for version control and team collaboration

jfrog
IncludedInteract with the JFrog Platform via the JFrog CLI and REST/GraphQL APIs. Use this skill when the user wants to manage Artifactory repositories, upload or download artifacts, manage builds, configure permissions, manage users and groups, work with access tokens, configure JFrog CLI servers, search artifacts, manage properties, set up replication, manage JFrog Projects, run security audits or scans, look up CVE details, query exposures scan results from JFrog Advanced Security, manage release bundles and lifecycle operations, aggregate or export platform data, or perform any JFrog Platform administration task. Also use when the user mentions jf, jfrog, artifactory, xray, distribution, evidence, apptrust, onemodel, graphql, workers, mission control, curation, advanced security, exposures, or any JFrog product name.
cupynumeric-migration-readiness
IncludedPre-migration readiness assessor for porting NumPy to cuPyNumeric. Use BEFORE substantial porting work begins when the user asks whether code will scale on GPU, whether they should migrate to cuPyNumeric, which NumPy patterns transfer cleanly, what must be refactored before porting, or mentions pre-port assessment, scaling analysis, or refactor planning. Inspect the user's source code, look up NumPy usage, cross-reference the cuPyNumeric API support manifest, and distinguish distributed-scaling-friendly patterns from blockers such as unsupported APIs, scalar synchronization, host round-trips, Python/object-heavy control flow, shape/data-dependent branching, and in-place mutation hazards. Produce a verdict of READY, LIGHT REFACTOR, SIGNIFICANT REFACTOR, or NOT RECOMMENDED, with concrete refactor pointers.
alibabacloud-data-agent-skill
IncludedInvoke Alibaba Cloud Apsara Data Agent for Analytics via CLI to perform natural language-driven data analysis on enterprise databases. Data Agent for Analytics is an intelligent data analysis agent developed by Alibaba Cloud Database team for enterprise users. It automatically completes requirement analysis, data understanding, analysis insights, and report generation based on natural language descriptions. This tool supports: discovering data resources (instances/databases/tables) managed in DMS, initiating query or deep analysis sessions, real-time progress tracking, and retrieving analysis conclusions and generated reports. Use this Skill when users need to query databases, analyze data trends, generate data reports, ask questions in natural language, or mention "Data Agent", "data analysis", "database query", "SQL analysis", "data insights".
token-optimizer
IncludedReduce OpenClaw token usage and API costs through smart model routing, heartbeat optimization, budget tracking, and native 2026.2.15 features (session pruning, bootstrap size limits, cache TTL alignment). Use when token costs are high, API rate limits are being hit, or hosting multiple agents at scale. The 4 executable scripts (context_optimizer, model_router, heartbeat_optimizer, token_tracker) are local-only — no network requests, no subprocess calls, no system modifications. Reference files (PROVIDERS.md, config-patches.json) document optional multi-provider strategies that require external API keys and network access if you choose to use them. See SECURITY.md for full breakdown.
resend-cli
IncludedUse this skill when the task is specifically about operating Resend from an AI agent, terminal session, or CI job via the official resend CLI: installing/authenticating the CLI, sending/listing/updating/cancelling emails, batch sends, domains and DNS, webhooks and local listeners, inbound receiving, contacts, topics, segments, broadcasts, templates, API keys, profiles, or debugging Resend CLI/API failures. Trigger on mentions of Resend CLI, `resend`, `resend doctor`, `resend emails send`, `resend domains`, `resend webhooks listen`, `resend emails receiving`, or agent-friendly terminal automation.
alibabacloud-odps-maxframe-coding
IncludedUse this skill for MaxFrame SDK development and documentation navigation on Alibaba Cloud MaxCompute (ODPS). Helps answer MaxFrame API, concept, official example, and supported pandas API questions; create data processing programs; read/write MaxCompute tables; debug jobs (remote or local); and build custom DPE runtime images. Trigger when users mention MaxFrame, MaxCompute with MaxFrame, ODPS table processing, DPE runtime, MaxFrame docs/examples, DataFrame/Tensor operations, or GPU runtime setup. Works for both English and Chinese queries about Alibaba Cloud data processing with MaxFrame.
