+# Set Permission Mode When Starting Session
+
+The way I typically use Claude Code day-to-day is with a couple long-running
+sessions for one to two clones of the project. I start a session with `claude`
+and then hit `shift+tab` until I've toggled it to _auto_ mode. I do tightly
+scoped features and `/clear` the context in between each.
+
+I get used to being in _auto_ mode, so whenever I start a new `claude` session I
+forget to first toggle from _manual_ to _auto_ mode.
+
+This is where the
+[`--permission-mode`](https://code.claude.com/docs/en/permission-modes) flag can
+help. I can start a session directly in _auto_ mode like so:
+
+```bash
+❯ claude --permission-mode auto
+```
+
+Or if I know I want to generate a plan first, I can start it in _plan_ mode.
+
+```bash
+❯ claude --permission-mode plan
+```
+
+There is also the `--dangerously-skip-permissions` flag which is equivalent to
+`--permission-mode bypassPermissions`. I tend to stay away from those unless I'm
+working from a sandboxed dev container.
+
+See `claude --help` for more details.
