Session Management

/context      # See what's consuming your context window
/compact      # Compress history — run at 70%, not the default 95%
/clear        # Wipe session between unrelated tasks
/cost         # Check token spend
/rewind       # Undo file changes and restore prior state

Planning & Execution

/plan <task>        # Claude explains every change before touching files
/goal <condition>   # Autonomous work until condition is met (e.g. "all tests pass")
/loop 5m <check>    # Recurring check on a schedule (e.g. monitor CI)
/branch             # Fork session to safely explore a risky approach
/ask <question>     # Side question — doesn't pollute main context

Model & Effort

/model claude-sonnet-4-6   # Switch to Sonnet for daily tasks
/model claude-opus-4-6     # Switch to Opus for complex reasoning
/model opusplan            # Opus thinking + Sonnet execution (best for refactors)
/effort low|medium|high|max

Code Quality

/code-review [high] [--fix]   # Review diff — optionally auto-fix
/simplify                     # Cleanup pass: remove duplication, improve readability
/security-review              # OWASP-mapped security audit

Agents & Parallelism

/agents       # Configure subagents with different models per role
/batch        # Run multiple independent tasks simultaneously

Project Setup (run once per repo)

/init         # Generate CLAUDE.md project memory
/permissions  # Set which tools Claude can run without asking
/mcp          # Manage connected MCP servers

Diagnostics

/doctor       # Health check + auto-fix
/help         # List all available commands
