Claude Code quick start

Connect Guard to Claude Code without losing your existing workflow.

Install GuardBack to install

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 Claude Code in one step.

Terminal

set -o pipefail; curl -fsSL https://hol.org/guard/install.sh | bash -s -- --harness claude-code --mode install --verify

Already have Guard installed? Skip to the harness command below. Full install guide.

Harness command

Attach to Claude Code

Terminal

hol-guard install claude-code

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

  • global Claude settings
  • project Claude settings
  • .mcp.json surfaces and local workspace agents

What install changes

  • Adds Guard hook entries to `.claude/settings.local.json` when you install.
  • Keeps wrapper mode available as the fallback path.

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 claude-code
2

Run the next verification commands

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

Command

hol-guard doctor claude-code
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 claude-code 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 preToolUse hook blocks execution inline, then opens the local approval center (browser, localhost) if a decision is needed.

Run command

hol-guard run claude-code

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 claude-code

Current phase notes

  • Claude Code's native tool approval surface is unchanged — Guard adds an additional pre-tool check via the hook system.
  • Hook registration writes to `.claude/settings.local.json`. Review this file to revert if needed.
