Claude Code

Account Types:

claude.ai/Claude Account/chat account/iOS app
Claude Developer Platform/Claude Console/Anthropic Console/platform.claude.com

Type / to get an autocomplete list of commands

Models
- Selecting: /model [sonnet|opus] - leave model out to check current one
- Which to use
  - Sonnet: daily driver
  - Opus: expensive but powerful
Write mode (shift-tab to toggle)
- Normal: have to approve everything
- Auto-accept edits
- Plan mode (don’t write to files)
Referencing files: @ prefix
Thinking mode
- Use phrasing like “think/think hard/think harder” (works in either Sonnet or Opus)
Context windows
- Will warn that auto-compact is coming soon
- /compact - Manually compact in advance so you don’t lose context in the middle of something you need it for
- /clear to fully clear context if done tasks
Rules - CLAUDE.md
- Put individual rules in here; not separate rules like Cursor
- Can be at user level, project level, and in project subdirs
- # command: create a memory and add it to the file
Commands: a shortcut for a repeated prompt
- Within it, ! interpolates a bash command
Subagents
- They have their own context window
- So when you have parts of the work that require different kinds of context, have different subagents, one per role
Misc
- /init
- /resume - pick up a conversation you left off in a previous run, can choose from a list
