> golang-logging
Standards for structured logging and observability in Golang. Use when adding structured logging or tracing to Go services. (triggers: go.mod, pkg/logger/**, logging, slog, structured logging, zap)
curl "https://skillshub.wtf/HoangNguyen0403/agent-skills-standard/golang-logging?format=md"Golang Logging Standards
Priority: P1 (STANDARD)
Principles
- Structured Logging: Use JSON or structured text. Readable by machines and humans.
- Leveled Logging: Debug, Info, Warn, Error.
- Contextual: Include correlation IDs (TraceID, RequestID) in logs.
- No
log.Fatal: Avoid terminating app inside libraries. Return error instead. Onlymainshould exit.
Libraries
log/slog(Recommended): Stdlib since Go 1.21. Fast, structured, zero-dep.- Zap (
uber-go/zap): High performance, good if pre-1.21 or extreme throughput needed. - Zerolog: Zero allocation, fast JSON logger.
Guidelines
- Initialize logger at startup.
- Inject logger or use a global singleton configured at startup (pragmatic choice).
- Use
slog.Attrfor structured data.

🚫 Anti-Patterns
- Do NOT use standard patterns if specific project rules exist.
- Do NOT ignore error handling or edge cases.

> typescript-tooling
Development tools, linting, and build config for TypeScript. Use when configuring ESLint, Prettier, Jest, Vitest, tsconfig, or any TS build tooling. (triggers: tsconfig.json, .eslintrc.*, jest.config.*, package.json, eslint, prettier, jest, vitest, build, compile, lint)
> typescript-security
Secure coding practices for TypeScript. Use when validating input, handling auth tokens, sanitizing data, or managing secrets and sensitive configuration. (triggers: **/*.ts, **/*.tsx, validate, sanitize, xss, injection, auth, password, secret, token)
> typescript-language
Modern TypeScript standards for type safety and maintainability. Use when working with types, interfaces, generics, enums, unions, or tsconfig settings. (triggers: **/*.ts, **/*.tsx, tsconfig.json, type, interface, generic, enum, union, intersection, readonly, const, namespace)
> typescript-best-practices
Idiomatic TypeScript patterns for clean, maintainable code. Use when writing or refactoring TypeScript classes, functions, modules, or async logic. (triggers: **/*.ts, **/*.tsx, class, function, module, import, export, async, promise)
