- Run Two Claude Code Sessions at Once With Git Worktrees: Setup, What Each Copy Shares, and Merging Back git worktree add ../proj-feature -b feature, then claude in that folder, or claude --worktree: both ways to give a second Claude Code session its own checkout.
- Resume a Claude Code Session: --continue, --resume, /resume, and Where Sessions Are Kept claude -c continues the latest conversation in the current directory; claude -r opens a picker or takes a session ID or name; /resume does the same from inside a session.
- Claude Code Hooks by Example: the Matcher, Each Event's JSON, and Exit Code 2 A Claude Code hook is a matcher plus a command in settings.json; the command gets the event as JSON on stdin and answers with an exit code or JSON on stdout.
- Claude Code Skills vs Slash Commands vs Subagents: the File Each One Is, and How to Check It A skill is .claude/skills/<skill-name>/SKILL.md, a custom slash command is a Markdown file in .claude/commands/ (the docs now call it the older format of a skill).
- Build a Claude Code Plugin, Install It From a Local Marketplace, and See Every File It Writes A Claude Code plugin marketplace is a folder with .claude-plugin/marketplace.json (name, owner, plugins), and each plugin in it has its own .claude-plugin/plugin.json (only name is required).
