CLAUDE.md files load at session start for always-on project context; rules in .claude/rules/ can be path-scoped to load only when relevant; skills in .claude/skills/ are reusable procedures that load on demand; subagents run isolated tasks in separate context windows; hooks provide deterministic automation triggered by lifecycle events; output styles inject instructions into the system prompt with highest authority; and appending the system prompt adds instructions additively without replacing defaults. The post provides a decision framework: use hooks for deterministic 'always do X' behaviors, path-scoped rules for file-specific constraints, skills for multi-step procedures, and subagents when side tasks would clutter the main conversation. Key advice includes keeping CLAUDE.md under 200 lines, using managed settings for organization-wide guardrails, and preferring built-in output styles before writing custom ones. ## Full article daily.dev links to this article rather than hosting it.
