Mechanisms

Sub-Agents, Slash Commands, Skills, Memory, Output-Styles

Feature	Invocation	Context	Use When
Sub-Agents	Automatic OR explicit	Separate context window per agent	You need specialized AI for specific tasks with focused tools/prompts
Slash Commands	Explicit (/command)	Adds to current conversation	You repeat the same prompt frequently
Skills	Automatic (Claude decides)	Progressive disclosure (loads files as needed)	Complex multi-file capability that Claude should discover automatically
CLAUDE.md	Automatic (loaded at startup)	Always in context	Persistent memory, preferences, conventions across sessions
Output Styles	Manual (/output-style)	Replaces system prompt	Change Claude's overall personality/behavior for entire session
