protect

A command that enables HOL Guard, a local security boundary for a coding-agent workspace. It checks whether the protection tool is available, detects supported agents, installs protection for selected agents, and verifies the result.

In plain words
What is it for?
Use it to protect supported local coding agents such as Claude Code, Codex, Copilot, Cursor, Gemini, or OpenCode.
Why use it?
It helps prevent an agent from proceeding when the local security enforcement tool denies or cannot verify an action. It also avoids exposing environment-file secrets during setup checks.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

protect scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Protect this workspace with HOL Guard

Use HOL Guard as the local security boundary for the active coding-agent workspace.

Safety rules

  • Do not read .env files or print secrets while checking the workspace.
  • Do not install packages or modify agent configuration unless the user asked to enable protection.
  • Fail closed if HOL Guard reports a denial, review requirement, malformed response, or unavailable enforcement hook.

Steps

  1. Check whether HOL Guard is already available:

    hol-guard status
    
  2. If hol-guard is unavailable, explain that the local prerequisite is:

    pipx install hol-guard
    

    Do not install it automatically without user intent.

  3. Detect supported local agent surfaces:

    hol-guard detect --json
    
  4. For each agent the user wants protected, use HOL Guard's existing installer. Examples:

    hol-guard install claude-code
    hol-guard install codex
    hol-guard install copilot
    hol-guard install cursor
    hol-guard install dsh
    hol-guard install gemini
    hol-guard install openclaw
    hol-guard install opencode
    hol-guard install antigravity
    
  5. Verify the resulting local protection:

    hol-guard status
    hol-guard detect --json
    

Report which requested agent surfaces are protected and surface any review or failure state instead of silently continuing.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

protect is a command published in the GitHub repository hashgraph-online/hol-guard-plugin (4 stars, last pushed 7d ago), licensed Apache-2.0. It adds 8 tokens to every session and 335 once invoked, about $0.0000 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
