Use nteract as your agent notebook

Install from the generated plugin marketplace at nteract/agent-plugins. The repository is produced by the nteract release pipeline, so the source of truth for changes remains the main nteract repo.

• nteract: the stable plugin channel for normal use.
• nightly: early access to the latest runtime and notebook tools.

/plugin marketplace add nteract/agent-plugins
/plugin install nteract@nteract       # stable
/plugin install nightly@nteract       # nightly

Claude Code pins plugins at install time. To install a known release, add --ref vX.Y.Z to the install command.

codex plugin marketplace add nteract/agent-plugins
# Then run /plugin in Codex and enable nteract or nightly

After registering the marketplace, start or restart Codex, run /plugin, pick the nteract marketplace, and enable the stable or nightly plugin. Codex resolves the platform-specific sidecar bundled with the plugin.

• Create or connect to notebook-backed Python sessions.
• Run code repeatedly while preserving variables and imports.
• Add dependencies before or during exploratory work.
• Inspect cells and outputs instead of reconstructing shell logs.
• Save the resulting notebook when the exploration is worth keeping.

In practice, this gives an agent a durable scratchpad that you can open in nteract, review, and continue working on yourself.

• If notebook tools do not appear, restart the agent after changing plugin or marketplace settings.
• If the stable channel is not enough, install the nightly plugin and try the same workflow there.
• If the agent reports runtime issues, open nteract locally and run runt doctor or runt-nightly doctor.
