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.
Generate API design stories from requirements, a domain model, and API standards. Stories bridge product requirements and OpenAPI specs — Emmanuel Paraskakis's method for designing APIs with LLMs. Use when user says "/design-api-stories" or asks to generate API user stories.

Generate and review Java code using patterns and best practices from Joshua Bloch's "Effective Java" (3rd Edition). Use this skill whenever the user asks about Java best practices, API design, object creation patterns, generics, enums, lambdas, streams, concurrency, serialization, method design, exception handling, or writing clean, maintainable Java code. Trigger on phrases like "Effective Java", "Java best practices", "builder pattern", "static factory", "defensive copy", "immutable class", "enum type", "generics", "bounded wildcard", "PECS", "stream pipeline", "optional", "thread safety", "serialization proxy", "checked exception", "try-with-resources", "composition over inheritance", "method reference", "functional interface", or "Java API design."
Configure and collect crash dumps for modern .NET applications. USE FOR: enabling automatic crash dumps for CoreCLR or NativeAOT, capturing dumps from running .NET processes, setting up dump collection in Docker or Kubernetes, using dotnet-dump collect or createdump. DO NOT USE FOR: analyzing or debugging dumps, post-mortem investigation with lldb/windbg/dotnet-dump analyze, profiling or tracing, or for .NET Framework processes.
Gin Go web framework. Covers routing, middleware, binding, validation, and rendering. Use for fast, minimalist Go APIs. USE WHEN: user mentions "gin", "gin-gonic", "go web framework", "go rest api", asks about "gin middleware", "gin binding", "gin validation", "gin router", "fast go api", "gin context" DO NOT USE FOR: Echo projects - use `echo` instead, Fiber projects - use `fiber` instead, Chi projects - use `chi` instead, non-Go backends
