Gateway Forward integrations require entrypoints, context handling, and continuation rules that differ from ordinary Workers. This skill guides implementation and validation using current Cloudflare references.

Software changes can repeat avoidable design, debugging, and verification mistakes. This skill gives coding assistants explicit engineering principles for making simpler, better-supported decisions.

Assumptions can lead to ineffective fixes and misleading performance claims. This skill guides assistants through hypotheses, predefined criteria, repeatable measurements, and evidence-based decisions.

New libraries often coexist with legacy implementations, leaving inconsistent usage across a codebase. This skill guides migration, standardizes usage, and requires automated constraints against legacy patterns.

React interfaces can become slow and difficult to maintain when state ownership and asynchronous dependencies are unclear. This skill guides stack-specific decisions with Effect Atom, TanStack Query, and concurrent React patterns.

Custom helpers can duplicate existing functionality and increase maintenance work. This skill guides library discovery and direct reuse before implementing only the missing behavior.

Manual Flutter UI checks are difficult to repeat consistently. This skill guides MCP exploration, integration test authoring, execution, and optional performance profiling.
