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
- Run the command above in their terminal.
- The dashboard will open automatically. If it doesn't, navigate to
http://localhost:4242 (or the port chosen).
- 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>.
