# HOL Guard

HOL Guard protects local AI harnesses before tools run. Use this skill when the user wants AI antivirus behavior, local approval review, Codex protection, Claude Code protection, MCP safety checks, skill/package verification, or release gates from `hol-guard` and `plugin-scanner`.

## Hard Rules

- Never read `.env` files.
- Never bypass Guard approvals.
- Do not mark a workspace protected until a Guard command proves status.
- Prefer reversible Guard commands over direct harness config edits.
- Do not mutate user-level harness config unless the `hol-guard` command owns that mutation.
- Treat scanner failures as real until inspected.
- Preserve existing user changes and inspect `git status --short` before edits in a repo.

## Install Check

First check whether the CLI exists:

```bash
command -v hol-guard
command -v plugin-scanner
```

If missing and the user asked for setup, prefer:

```bash
pipx install hol-guard
```

Fallback only when `pipx` is unavailable:

```bash
python3 -m pip install --user hol-guard
```

After install:

```bash
hol-guard status
hol-guard detect --json
```

## Protect A Local Harness

Use this flow for Codex, Claude Code, Copilot CLI, Cursor, Gemini, Hermes, OpenClaw, OpenCode, or Antigravity.

```bash
hol-guard bootstrap
hol-guard install <harness>
hol-guard run <harness> --dry-run
hol-guard run <harness>
hol-guard status
```

Harness names:

- `codex`
- `claude-code`
- `copilot`
- `cursor`
- `gemini`
- `hermes`
- `openclaw`
- `opencode`
- `antigravity`

Harness aliases:

- `claude` maps to `claude-code`
- `gemini-cli` maps to `gemini`
- `open-code` maps to `opencode`
- `open-claw` maps to `openclaw`
- `copilot-cli` maps to `copilot`

Use harness-specific bootstrap when available:

```bash
hol-guard hermes bootstrap
```

### Claude Code

Use this when the workspace has `.claude/settings.local.json`, `.claude/agents`, Claude hooks, `.mcp.json`, or Claude-managed tool approval surfaces.

```bash
hol-guard install claude-code
hol-guard run claude-code --dry-run
hol-guard run claude-code
hol-guard doctor claude-code --json
```

Claude Code is a first-class Guard target. Prefer Guard-owned Claude hooks over direct manual edits to Claude config.

### Codex

Use this when the workspace has Codex config, `.codex/hooks.json`, Codex MCP servers, or Codex App/CLI tool flows.

```bash
hol-guard install codex
hol-guard run codex --dry-run
hol-guard run codex
hol-guard doctor codex --json
```

Codex supports Guard-owned `PreToolUse` Bash hooks and same-chat MCP elicitation where available.

### Other Harnesses

Use the same Guard flow for:

- Copilot CLI: `hol-guard install copilot`
- Cursor: `hol-guard install cursor`
- Gemini CLI: `hol-guard install gemini`
- Hermes: `hol-guard hermes bootstrap`
- OpenClaw: `hol-guard install openclaw`
- OpenCode: `hol-guard install opencode`
- Antigravity: `hol-guard install antigravity`

## Approval Work

If Guard blocks or queues work:

```bash
hol-guard approvals
hol-guard approvals open
hol-guard receipts
hol-guard diff <harness>
```

For terminal-only resolution:

```bash
hol-guard approvals approve <request-id>
hol-guard approvals deny <request-id>
```

Only approve after reading the risk reason and understanding the requested scope.

## Evidence Work

Use evidence commands when user needs proof, audit trail, or handoff artifacts:

```bash
hol-guard receipts
hol-guard inventory
hol-guard abom --format json
hol-guard events
hol-guard explain <artifact-id>
```

For cloud sync, keep it optional and user-directed:

```bash
hol-guard connect
hol-guard connect status
hol-guard connect repair
hol-guard sync
```

## Scan A Plugin Or Skill Package

Use scanner mode for Codex plugins, Claude Code project surfaces, `.agents` marketplaces, skills, MCP server configs, and release gates.

```bash
plugin-scanner lint .
plugin-scanner verify .
```

If scanning a specific package:

```bash
plugin-scanner lint <path>
plugin-scanner verify <path>
```

If the target is a Codex marketplace root with `.agents/plugins/marketplace.json`, scan the repo root so local plugin entries can be discovered.

Scanner target guidance:

- Codex plugin: scan the repo root or plugin folder containing `.codex-plugin/plugin.json`.
- Codex marketplace: scan the repo root containing `.agents/plugins/marketplace.json`.
- Claude Code project: scan the workspace root containing `.claude/`, `.mcp.json`, hooks, or agent folders.
- MCP server package: scan the package root containing server config and package metadata.
- Skill package: scan the folder containing `SKILL.md`.
- Mixed agent workspace: scan the repo root so local plugin, skill, MCP, and harness config surfaces are discovered together.

## Common Debug Commands

```bash
hol-guard doctor
hol-guard doctor <harness> --json
hol-guard detect --json
hol-guard settings show
hol-guard explain install-connect
plugin-scanner verify . --json
```

## Response Pattern

When using Guard, report:

- What command ran.
- What Guard found.
- What remains blocked or risky.
- What proof exists.
- Exact next command if user must act.

Do not claim protection, approval, or release readiness without command output proving it.

## Local Helper

This plugin includes:

```bash
bash scripts/hol-guard-plugin status
bash scripts/hol-guard-plugin harnesses
bash scripts/hol-guard-plugin protect claude-code
bash scripts/hol-guard-plugin protect <harness>
bash scripts/hol-guard-plugin scan-system claude <path>
bash scripts/hol-guard-plugin scan-system codex <path>
bash scripts/hol-guard-plugin scan <path>
bash scripts/hol-guard-plugin evidence
```

Use the helper only when running from this plugin repository. Otherwise call `hol-guard` and `plugin-scanner` directly.
