10| Command | What it does |
11| ----------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
12| `claude-science serve` | Start the background program and open the web app in your browser at a single-use login link. One runs per data directory; Ctrl-C stops it. |
13| `claude-science open` | Mint a fresh login link from the running program and open it in your browser. |
14| `claude-science url` | Print a fresh login link alone on standard output and nothing else. |
15| `claude-science status` | Print whether the program is running, the version, and the port, as JSON. |
16| `claude-science logs` | Print the newest log file from the data directory. `--tail` follows it live. |
17| `claude-science stop` | Stop the program cleanly. |
18| `claude-science update` | Check for and install an update. `--check` only reports; --to `<version>` installs a specific version, which is also how you roll back. Updates are signature-verified and replace the binary atomically. |
19| `claude-science import` `<path>` | Merge another data directory, or its database file, into this one. |
20| `claude-science uninstall` | Windows only. Remove the app, its shortcuts, and its PATH entry while keeping your data; `--purge` also deletes the data directory. Quit Claude Science first. |
21| `claude-science --version` | Print the version. |
22| `claude-science` `<command>` --help | Print help for any command. |

2525 `import` has no preview and no undo. Back up the data directory before you run it; running the same import a second time is safe.

45| ------------------------- | --------- | ------------------------------------------------------------------------------------------------------------------------------- |
46| `--port` `<n>` | `8000` | The port the web app is served on. 0 picks a free port. |
47| `--no-browser` | off | Do not open a browser. url prints a login link any time you want one. |
48| `--detached` | off | Run in the background. Implies --no-browser. |
49| `--no-auto-update` | off | Do not check for or install updates. For a pinned or centrally managed install. |
50| `--host` `<address>` | 127.0.0.1 | The address the app listens on. Anything else exposes the app to your network; prefer an SSH tunnel. |
51| `--base-path` `</prefix>` | unset | Serve the app under a URL prefix behind a reverse proxy. |
52| `--allow-origin` `<url>` | unset | An extra browser Origin allowed to connect; repeat the flag for more than one. It does not change which sites Claude can reach. |

54| `--verbose` | off | Show startup and info log lines on the console; by default they go only to the log file. |
