pulumi neo local agent workflow and TUI

Introduced 2026-04-23 · score 0.93

HOW TO USE IT

When a repository task needs local agent inspection or edits, authenticate with `pulumi login` and run `pulumi neo` from a directory containing `Pulumi.yaml` with `PULUMI_EXPERIMENTAL=true`. Use the TUI to direct the task; press Shift+Tab before the first message to enable plan mode, and press Esc during a turn to request cancellation.

PULUMI_EXPERIMENTAL=true pulumi neo

WHY THIS HELPS

For a repository task that needs a local agent to inspect or edit files and propose changes, start `pulumi neo` and use its terminal UI to direct the task.

REQUIREMENTS AND LIMITATIONS

  • Version: v3.232.0
  • Availability: Experimental; hidden behind PULUMI_EXPERIMENTAL.
  • PULUMI_EXPERIMENTAL (required): Set to `true` to enable experimental commands and options.
  • prompt: Optional positional prompt; without one, the TUI starts and waits for the first message.
  • Shift+Tab: Toggles plan mode; enable it before sending the first message. Approving the proposed plan exits plan mode automatically.
  • Esc: During a turn, requests agent cancellation.
  • Prerequisite: Authenticate to Pulumi Cloud with `pulumi login`; run `pulumi neo` from a directory containing `Pulumi.yaml`.
  • Prerequisite: Set `PULUMI_EXPERIMENTAL=true` to enable experimental commands.
  • Plan mode must be set before the first message because it is task-level on the wire.
  • Approving the proposed plan exits plan mode automatically.
  • The TUI prompts for approval when the agent requests confirmation for a sensitive action and forwards the response to the Pulumi Console.
  • Filesystem and shell tool calls run on the user's machine in their working directory.
  • The edit tool creates a new file when the target is missing and old_string is empty.
  • Docs conflict: The current generated command reference is for Pulumi CLI v3.268.0, newer than the card's v3.232.0; its additional options are not included here.
