golang-configuration
Standards for application configuration using environment variables and libraries. Use when managing Go application config with environment variables or viper. (triggers: configs/**, cmd/**, configuration, env var, viper, koanf)
Best use case
golang-configuration is best used when you need a repeatable AI agent workflow instead of a one-off prompt.

Teams using golang-configuration should expect a more consistent output, faster repeated execution, less prompt rewriting.
When to use this skill
- You want a reusable workflow that can be run more than once with consistent structure.
When not to use this skill
- You only need a quick one-off answer and do not need a reusable workflow.
- You cannot install or maintain the underlying files, dependencies, or repository context.

# Golang Configuration Standards ## **Priority: P1 (STANDARD)** ## Principles - **12-Factor App**: Store config in environment variables. - **Typed Config**: Load config into a struct, validate it immediately. - **Secrets**: Never commit secrets. Use env vars or secret managers. - **No Globals**: Return a Config struct and inject it. ## Libraries - **Standard Lib**: `os.Getenv` for simple apps. - **Viper**: Industry standard for complex configs (supports env, config files, remote config). - **Koanf**: Lighter, cleaner alternative to Viper. - **Caarlos0/env**: Good for strict struct tagging. ## Pattern 1. Define `Config` struct. 2. Load from defaults. 3. Override from file (optional). 4. Override from Env (priority). 5. Validate. ## References - [Config Pattern](references/config-patterns.md) ## Anti-Patterns - **No hardcoded secrets**: Load all secrets from env vars or a secret manager. - **No global config vars**: Return a typed Config struct and inject it via constructors. - **No startup without validation**: Crash immediately on missing required env vars.

## Overview
finding-security-misconfigurations
This skill enables Claude to identify potential security misconfigurations in various systems and configurations. It leverages the security-misconfiguration-finder plugin to analyze infrastructure-as-code, application configurations, and system settings, pinpointing common vulnerabilities and compliance issues. Use this skill when the user asks to "find security misconfigurations", "check for security vulnerabilities in my configuration", "audit security settings", or requests a security assessment of a specific system or file. This skill will assist in identifying and remediating potential security weaknesses.
