Setup snapshot

git clone https://github.com/metterian/claude-code-best-practices.git

1
Setup complexity is LOW. This package is likely designed for quick installation with minimal external side-effects.
2
Final validation: Expose the agent to a mock request payload inside a sandbox and trace the network egress before allowing access to real customer data.

Usage

Find examples: Read files from references/everything-claude-code/ matching your need
Adapt patterns: Modify examples for your project context
Follow conventions: Use frontmatter format, imperative language, concise instructions

Key Principles

Context window: Limit active MCPs (<10 per project, <80 tools)
Progressive disclosure: Keep SKILL.md lean, split details to references
Modular rules: One concern per rule file
Delegated tasks: Use subagents for scoped work (review, planning, testing)
