Launch the memhub web dashboard for this repo.

This is the Codex counterpart to the Claude Code /viz skill. Both invoke the same memhub viz binary; they differ only in the agent identifier on whatever read-side telemetry the host captures.

Preconditions

• .memhub/ exists in the working repo (run /check-init if unsure).
• memhub binary on PATH and compiled with the viz feature (default build).

Invocation

memhub viz --open

This starts a local HTTP server (default port 4242) and opens the dashboard in the default browser. The server runs until you stop it (Ctrl-C).

If the default port is taken, pass an explicit one:

memhub viz --port 4243 --open

What to tell the user

1. Run the command above in their terminal.
2. The dashboard will open automatically. If it doesn't, navigate to http://localhost:4242 (or the port chosen).
3. To stop the server, press Ctrl-C in the terminal where it's running.

Error handling

• memhub viz was compiled out → the binary was built without the viz feature. Rebuild with cargo build --release (the feature is on by default).
• No such file or directory: .memhub/project.sqlite → memhub hasn't been initialized in this repo. Run memhub init first.
• Port already in use → retry with --port <other>.
