claude, claude+, claude++

• claude = plain Claude Code, asks before every action
• claude+ = claude --dangerously-skip-permissions
• Auto-approve, start with: claude+ "your task"
• claude++ = claude --dangerously-skip-permissions --continue
• Reopens your last conversation, e.g. after /exit to add an MCP server
• Auto-approve is fine here: a disposable cloud computer

/model: brain and effort

• /model = opens the model picker
• Up/Down = pick a model, Left/Right = set the effort
• Effort = how hard it thinks: low, medium, high, xhigh, max
• Enter = switch and keep it for new sessions
• s = this session only, Esc = cancel
• Shortcut: /model opus or /model sonnet switches at once

Which model when

• Sonnet 5.5 = your default here, medium effort, everyday work
• Opus 5.5 = the hard tasks, twice the Sonnet price
• Haiku 5.5 = quick bulk work, 1/20 of the Sonnet price
• Fable 5.1 = never today, five times the Sonnet price
• Stuck on a hard problem: /model opus, later /model sonnet
• More thinking, same model: /effort high

Esc, Shift+Tab, Ctrl+C

• Esc = stop Claude mid-answer, the work so far stays
• Esc Esc = rewind to an earlier point, same as /rewind
• Shift+Tab = next mode, e.g. Plan: it plans, you approve
• Ctrl+C = stop; on an empty prompt press twice to quit
• /exit = close Claude, claude++ brings it back
• Wrong direction? Esc, then just say what you want
