Pi / Oh My Pi quick start

Put Guard in front of Pi (Oh My Pi) so risky tool calls and config changes are caught before launch.

Prerequisite

Install Guard

If you haven't installed Guard yet, run the install script first. This installs hol-guard via pipx and configures it for Pi / Oh My Pi in one step.

Smoke command

Known blind spot

Pi package install and update flows happen outside the runtime extension bridge, so Guard observes the configured package surfaces plus the prompt and tool events forwarded by the managed extension.

Harness command

Attach to Pi / Oh My Pi

Terminal

hol-guard install pi

Guard stays local by default — no account required to protect your first session. Connect Guard Cloud later to sync security records across your devices.

What Guard checks

  • ~/.pi/config.json
  • declared MCP server entries and tool surfaces
  • linked extension and plugin paths

What install changes

  • Installs Guard in wrapper mode so you can protect Pi without changing your existing setup.
  • Keeps a local security record for every approval and block so your team can reuse past decisions.

Verification

Confirm the setup before your first protected session.

1

Run the setup command

Start with the Guard command matched to this AI coding app and its setup mode.

Command

hol-guard install pi
2

Run the next verification commands

Confirm Guard sees the expected config paths before your first protected session.

Command

hol-guard doctor pi
hol-guard run pi --dry-run
3

Check your first security record

After Guard records a local decision, open the receipt list to confirm what was scanned.

Command

hol-guard receipts

Safe demo & test protection

Use --dry-run for demos and CI. Guard scans and reports without blocking, so you can show what it catches without interrupting a live session.

Sync to Guard Cloud

Connect Guard Cloud to carry your security records, team memory, and approval history across every machine and teammate — no rebuilding approvals when you switch devices.

Troubleshooting

Something not working?

  • Guard does not intercept launches

    Run hol-guard doctor pi and check that the wrapper path matches your installed binary.

  • No security record after the first run

    Check that ~/.hol-guard/ is writable. Guard writes every decision there by default.

  • Cloud sync not reflecting local decisions

    Run hol-guard sync --status to see if Guard Cloud can reach the server. Local protection keeps running even when sync is unavailable.

Approval surface

Guard local approval center (browser, localhost) via wrapper mode — opens when a new or changed tool call or config entry needs a decision.

Run command

hol-guard run pi

Uninstall / revert

Guard leaves no background services. Your approval history stays on disk in ~/.hol-guard/ unless you delete that folder.

Uninstall command

hol-guard uninstall pi

Current phase notes

  • Inline file edits applied directly by the model without a tool call are not visible to Guard.
  • Pi native approval surface is not replaced — Guard intercepts at the wrapper layer.
