Connect SaaS data (HubSpot, Stripe, Salesforce, GitHub, Slack, etc.) to Wren Engine for SQL analysis. Guides the user through the full flow: install dlt, pick a SaaS source, set up credentials, run the data pipeline into DuckDB, then auto-generate a Wren semantic project from the loaded data. Use this skill whenever the user mentions: connecting SaaS data, importing data from an API, dlt pipelines, loading HubSpot/Stripe/Salesforce/GitHub/Slack data, querying SaaS data with SQL, or setting up a new data source from a REST API. Also trigger when the user already has a dlt-produced DuckDB file and wants to create a Wren project from it.

Huzzler platform help — founder community and weekly product launch competition for startups. Covers Launch Arena (Mon-Wed submissions, Wed-Sun voting, Gold/Silver/Bronze badges with dofollow backlinks for winners only), community categories (#feedback, #showcases, #wins, #growth, #marketing), Huzzler Black ($79 one-time — lifetime premium visibility, verified badge, SEO boost, no ads), product showcases, Stripe-verified MRR, advertising credits ($34 promoted), AI-free community policy, and referral system.

Guide the user through connecting a new data warehouse source — Postgres, MySQL, Stripe, Hubspot, MongoDB, Salesforce, BigQuery, Snowflake, and so on. Use when the user wants to "connect Stripe", "import data from Postgres", "add a new data source", "sync my warehouse tables", or wants to pick sync methods for each table. Walks through source-type discovery, credential validation, table discovery, per-table sync_type selection, and the final create call. Also covers picking a good prefix and what to do right after creation.
Reads AR/AP, historical cash timing, and known fixed costs from QuickBooks, PayPal, Stripe, or Square — or a CSV upload — and produces a 30/60/90-day cash flow forecast with percentage-variance confidence bands and named risk flags. Delivers a chat summary and a downloadable XLSX. Use when the user asks "forecast my cash flow," "will I make payroll," mentions "runway," or says "cash crunch." Falls back to CSV upload when no connector is live.
Hunting skill for business logic vulnerabilities. Built from 12 public bug bounty reports. Covers coupon-race-stacking (Instacart, Stripe, Reverb), negative-quantity-in-cart price tampering (Upserve, Eternal/Zomato), decimal/fraction price-field overflow (Shipt), client-side checkout amount trust on PayPal redirect (WordPress.org), price-per-unit mass-assignment (Krisp), and archived-price swap / cart-TOCTOU (Stripe). Use when hunting business logic — heavy emphasis on financial-impact-demonstrated cases.
Use when building or maintaining real-time collaborative apps with the DeepSpace SDK on Cloudflare Workers — scaffolding new apps, adding features, debugging a `worker.ts` that imports from `deepspace` / `deepspace/worker` or uses `RecordRoom`, `__DO_MANIFEST__`, or `npx deepspace`. Also use when the user mentions DeepSpace or app.space, or asks for anything involving real-time sync, multiplayer state, live cursors / presence, whiteboards or canvases, collaborative text editing (Yjs), channel-based chat, per-role permissions (RBAC), Durable Object rooms, Stripe-backed subscriptions / paywalls / one-time products / tips / refunds, or one-package deploy to `.app.space` — even if they don't name DeepSpace explicitly.
Build reliable third-party API integrations including OAuth, webhooks, rate limiting, error handling, and data sync. Use when integrating with external services (Slack, Stripe, Gmail, etc.), building API connections, handling webhooks, or implementing OAuth flows.
