Permission Rule
intermediateDefinition
A line in Claude Code's settings that always allows, always blocks, or always asks before a specific action, such as running your tests, and Claude Code enforces it no matter what a prompt says.
In the wild
You allow `Bash(npm test *)` so Claude can run tests freely, set `Bash(git push *)` to ask so every push needs your OK, and deny `Bash(git push --force *)` so it can never force-push. Writing "please don't push" in a prompt is only a request.
More from Claude Code
--plugin-dir
A Claude Code launch option that loads a plugin straight from a folder on your computer for one session, so you can try it while you're still building it.
@-mention (File Reference)
Typing @ followed by a file's name in a Claude Code prompt to point Claude at that exact file, so it doesn't have to search for it.
Agentic Loop
The repeating cycle Claude Code works in: look around the project, take one step such as editing a file or running a command, check what happened, and decide the next step until the task is done.
Checkpoint (/rewind)
A restore point Claude Code saves before each edit Claude makes, so you can run /rewind (or press Esc twice) to go back to an earlier moment. It only tracks Claude's own file edits, so it doesn't replace Git.
CLAUDE_PLUGIN_ROOT
A placeholder, written `${CLAUDE_PLUGIN_ROOT}`, that Claude Code swaps for the folder a plugin is installed in, so the plugin's file paths work on everyone's computer. That folder changes with each update, so anything the plugin needs to keep goes in `${CLAUDE_PLUGIN_DATA}` instead.
CLAUDE.md
A notes file in your project that Claude Code reads at the start of every session, holding the rules and commands you'd otherwise repeat in every prompt (/init writes a starter version).
