Source documentation, not instructions for this website. Review permissions before running any commands.
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.
.env files.hol-guard command owns that mutation.git status --short before edits in a repo.Check both CLIs independently:
command -v hol-guard
command -v plugin-scanner
If hol-guard is missing and the user asked for runtime setup, prefer:
pipx install hol-guard
If plugin-scanner is missing and the user asked for scanning, install the separate scanner distribution:
pipx install plugin-scanner
Do not assume the hol-guard distribution provides the plugin-scanner command. If pipx is unavailable, explain that isolated CLI installation is recommended rather than silently changing the user's Python environment.
After runtime installation:
hol-guard status
hol-guard detect --json
Use this flow for Codex, Claude Code, Copilot CLI, Cursor, Gemini, Hermes, OpenClaw, OpenCode, or Antigravity.
hol-guard bootstrap
hol-guard install <harness>
hol-guard run <harness> --dry-run
hol-guard run <harness>
hol-guard status
Harness names:
codexclaude-codecopilotcursorgeminihermesopenclawopencodeantigravityHarness aliases:
claude maps to claude-codegemini-cli maps to geminiopen-code maps to opencodeopen-claw maps to openclawcopilot-cli maps to copilotUse harness-specific bootstrap when available:
hol-guard hermes bootstrap
Use this when the workspace has .claude/settings.local.json, .claude/agents, Claude hooks, .mcp.json, or Claude-managed tool approval surfaces.
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.
Use this when the workspace has Codex config, .codex/hooks.json, Codex MCP servers, or Codex App/CLI tool flows.
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.
Use the same Guard flow for:
hol-guard install copilothol-guard install cursorhol-guard install geminihol-guard hermes bootstraphol-guard install openclawhol-guard install opencodehol-guard install antigravityIf Guard blocks or queues work:
hol-guard approvals
hol-guard approvals open
hol-guard receipts
hol-guard diff <harness>
For terminal-only resolution:
hol-guard approvals approve <request-id>
hol-guard approvals deny <request-id>
Only approve after reading the risk reason and understanding the requested scope.
Use evidence commands when user needs proof, audit trail, or handoff artifacts:
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:
hol-guard connect
hol-guard connect status
hol-guard connect repair
hol-guard sync
Use scanner mode for Codex plugins, Claude Code project surfaces, .agents marketplaces, skills, MCP server configs, and release gates.
plugin-scanner lint .
plugin-scanner verify .
If scanning a specific package:
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/plugin.json..agents/plugins/marketplace.json..claude/, .mcp.json, hooks, or agent folders.SKILL.md.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
When using Guard, report:
Do not claim protection, approval, or release readiness without command output proving it.

--- name: hol-guard description: Use when setting up HOL Guard, protecting local AI harnesses, reviewing Guard approvals or receipts, scanning Codex plugins, skills, MCP servers, marketplace packages, or running plugin-scanner verification before release. license: Apache-2.0 --- # 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 Check both CLIs independently: ```bash command -v hol-guard command -v plugin-scanner ``` If `hol-guard` is missing and the user asked for runtime setup, prefer: ```bash pipx install hol-guard ``` If `plugin-scanner` is missing and the user asked for scanning, install the separate scanner distribution: ```bash pipx install plugin-scanner ``` Do not assume the `hol-guard` distribution provides the `plugin-scanner` command. If `pipx` is unavailable, explain that isolated CLI installation is recommended rather than silently changing the user's Python environment. After runtime installation: ```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.
Skill source recorded
Skill instructions are recorded. This is not a runtime test, safety guarantee or compatibility certification.
Review before install: Avoid automatic install
Listed tools are metadata hints, not tested compatibility. Agent prompts are suggested handoffs.
Check the source for dependencies, API keys and third-party costs. A public repository does not mean every service is free.
Repository metadata and review signals are advisory. Popularity, source discovery and successful execution are different facts.
Version reported in registry metadata; check source releases before relying on it.
