Overview of the Neon platform for apps and agents, spanning Postgres, Auth, Data API, and the new services: Object Storage, Compute Functions, and AI Gateway. Use whenever "Neon" is mentioned for an overview of how to work with Neon and how to get started. Otherwise, the individual capabilities are the triggers: "object storage" or "S3-compatible storage", "serverless functions", "background jobs", or "run code near my database", "AI gateway", "LLM proxy", "model routing", or "call an LLM" → AI Gateway; "database", "Postgres", or "authentication" → Postgres and Auth.

Expert-level development skill for building, debugging, reviewing, and migrating Freshworks Platform 3.0 marketplace applications. REQUIRES Node.js 24.x + FDK 10.x installed BEFORE use—checks prerequisites and refuses to proceed without them. Does NOT install or manage FDK/Node—use fw-setup skill. Before fdk validate, follow this SKILL.md Manifest + toolchain gate (fw-setup if CLI wrong, /fdk-migrate on 2.x or legacy engines, then validate—never downgrade to FDK 9/Node 18 as a shortcut except LAST RESORT after six validate iterations). New apps default to FDK 10.0.1 and Node.js 24.x; FDK 9.x/Node 18.x allowed when explicitly requested with deprecation notice. Use for: (1) Creating Platform 3.0 apps (frontend, serverless, hybrid, OAuth), (2) Debugging validation errors, (3) Migrating Platform 2.x apps to 3.0, (4) Reviewing manifest.json, requests.json, oauth_config.json, (5) Implementing Crayons UI, (6) Integrating external APIs or OAuth providers, (7) Any Freshworks Platform 3.0 app development, FDK CLI, or marketplace submission task.
