Organize reusable programming patterns / library usages / technical skills that answer "To do this kind of thing, the correct approach is this" into a prescriptive reference library, which can be retrieved and reused as needed during feature-design and issue-analyze phases. Three types: pattern (design patterns, programming idioms), library (usage and pitfalls of a certain library/framework), technique (specific operation skills / command recipes). Trigger scenarios: When the user says "record a trick", "this usage is worth recording", "tricks", "record library usage", or when a skill worth archiving is discovered during feature-design / issue-analyze phases and actively pushed. Refer to `codestable/reference/system-overview.md` for how to distinguish it from learning / decisions / explore.
Project Guidelines Skill (Example)
Use React/React Native code as the source of truth and implement the equivalent feature in iOS/Swift. Understands the feature behavior, components, state management, and logic from React, then creates idiomatic iOS code that matches the target codebase's existing patterns. Use when porting features from React/React Native to native iOS or building native alternatives to web components.
Complete React Native and Expo optimization guide combining Callstack profiling with Vercel code patterns. Covers FPS, TTI, bundle size, memory, lists, animations, state, UI, and React Compiler. Use for any React Native performance, debugging, or best practices task.
Organize reusable programming patterns, library usages, and technical techniques that address "This is the correct way to do such tasks" into a prescriptive reference library, which can be retrieved and reused on demand during feature-design and issue-analyze phases. There are three types: pattern (design patterns, programming idioms), library (usage and pitfalls of a specific library/framework), technique (specific operation skills / command recipes). Trigger scenarios: when users say "Record a trick", "This usage is worth noting", "tricks", "Record library usage", or when valuable techniques worth documenting and archiving are discovered during feature-design / issue-analyze phases and actively pushed. For how to distinguish it from learning / decisions / explore, refer to the root skill of `easysdd`.
Use when creating GitHub Copilot instructions - provides repository-wide and path-specific formats, applyTo patterns, excludeAgent options, and natural language markdown style
Analyze existing code to generate structured learning entries documenting patterns, decisions, and concepts. Works on files, directories, or entire projects. Supports selective (3-5 per file) and exhaustive modes, plus source annotations for fine-grained control.
Learn unfamiliar implementation patterns and fill in missing pieces when building features in a specific environment (e.g., data fetching in a particular runtime). Use when you need to discover or confirm patterns for an unimplemented area; implementation uses erudita and osgrep.
Master Dart/Flutter performance optimization including efficient code patterns, data structure selection, and compilation benefits.
Explores codebase to find patterns, similar features, and constraints
Use when implementing features, writing fullstack code, shipping UI + API + DB changes, or any hands-on engineering work in TypeScript, Python, React, Next.js, FastAPI, or SQL
Essential patterns, idioms, and gotchas for writing Nushell code. Use when writing Nushell scripts, functions, or working with Nushell's type system, pipelines, and data structures. Complements plugin development knowledge with practical usage patterns.
