// Go development best practices. Idiomatic Go, error handling, concurrency patterns, testing. Use when writing Go code.
C++ development best practices. Modern C++20/23, RAII, zero-overhead abstractions, safety. Use when writing C++ code.
Docker and container best practices. Multi-stage builds, security, optimization. Use when creating Dockerfiles.
Observability best practices. Logging, metrics, tracing, alerting. Essential for production services. Use for any backend service.
React Native development. Cross-platform code, native modules, performance. Use when building mobile apps.
Test-Driven Development workflow. Write failing test first, implement code to pass, then refactor. Essential for all languages: Go, TypeScript, C++, Python. Use before any implementation task.
Use when the user wants to commit, push, and open a pull request for the current changes. Stages relevant files, writes a descriptive commit message, pushes the branch, opens a PR against main, and posts an /oc review comment so opencode automatically reviews and approves if ready.

// Always wrap errors with context

// Use channels for coordination, mutexes for state
// Worker pool pattern
