Analyze network latency and optimize request patterns for faster communication. Use when diagnosing slow network performance or optimizing API calls. Trigger with phrases like "analyze network latency", "optimize API calls", or "reduce network delays".
Optimize Evernote integration performance. Use when improving response times, reducing API calls, or scaling Evernote integrations. Trigger with phrases like "evernote performance", "optimize evernote", "evernote speed", "evernote caching".
Guide for writing Apollo Router native Rust plugins. Use this skill when: (1) users want to create a new router plugin, (2) users want to add service hooks (router_service, supergraph_service, execution_service, subgraph_service), (3) users want to modify an existing router plugin, (4) users need to understand router plugin patterns or the request lifecycle. (5) triggers on requests like "create a new plugin", "add a router plugin", "modify the X plugin", or "add subgraph_service hook".
Best practices and usage guide for the JAW SDK (@jaw.id/core, @jaw.id/wagmi, @jaw.id/ui). Use this skill when writing code that uses jaw-sdk or @jaw.id packages, integrating JAW smart accounts into an application, configuring JAW SDK features (passkeys, permissions, gas sponsoring, ENS), building with JAW wagmi hooks, implementing headless/server-side smart account operations, debugging JAW SDK issues, or when asked about JAW SDK patterns, APIs, or best practices.
Thin HTTP layer controllers. Controllers contain zero domain logic, only HTTP concerns. Use when working with controllers, HTTP layer, web vs API patterns, or when user mentions controllers, routes, HTTP responses.
Use proactively when encountering Rails errors, test failures, build issues, or unexpected behavior. Analyzes errors, reproduces issues, and identifies root causes.

Use when asked to "write Python code", "explain Python concepts", "set up a Python project", "configure Poetry or PDM", "write pytest tests", "create a FastAPI endpoint", "run uvicorn server", "configure alembic migrations", "set up logging", "process data with pandas", or "debug Python errors". Triggers on "Python best practices", "type hints", "async Python", "packaging", "virtual environments", "Pydantic validation", "dependency injection", "SQLAlchemy models".
Response streaming configuration and real-time output
Redis mastery for caching, data structures, pub/sub, and CLI operations. Use when user asks to "set up Redis", "cache data", "redis commands", "pub/sub", "redis data types", "session store", "rate limiting with Redis", or any Redis tasks.
Zig compiler skill for systems programming. Use when compiling Zig programs, selecting optimization modes, using zig cc as a C compiler, reading Zig error messages, or understanding Zig's compilation model. Activates on queries about zig build-exe, zig build-lib, optimize modes, ReleaseSafe, ReleaseFast, ReleaseSmall, zig cc, zig ast-check, or Zig compilation errors.
Dynamic linking skill for Linux/ELF shared libraries. Use when debugging library loading failures, configuring RPATH vs RUNPATH, understanding soname versioning, using dlopen/dlsym for plugin systems, LD_PRELOAD interposition, or controlling symbol visibility. Activates on queries about shared libraries, dlopen, LD_LIBRARY_PATH, RPATH, soname, LD_PRELOAD, symbol visibility, or "cannot open shared object file" errors.
This skill should be used when implementing Convex mutation functions. It provides comprehensive guidelines for defining, registering, calling, and scheduling mutations, including database operations, transactions, and scheduled job patterns.
