# OpenClaw Hardener

This skill provides a **user-choice** hardening tool that can:

- Run OpenClaw’s built-in security audit (`openclaw security audit --deep` / `--fix`).
- Run workspace hygiene checks (exec bits, stray `.env`, unsafe serialization patterns, etc.).
- Apply safe mechanical fixes **only when explicitly requested**.
- Generate (and optionally apply) a **Gateway `config.patch` plan** to tighten runtime policy.

## Run the tool

Script:
- `skills_live/openclaw-hardener/scripts/hardener.py`

Examples:

```bash
# Read-only checks (recommended default)
python3 skills_live/openclaw-hardener/scripts/hardener.py check --all

# Only run OpenClaw built-in audit (deep)
python3 skills_live/openclaw-hardener/scripts/hardener.py check --openclaw

# Only run workspace checks
python3 skills_live/openclaw-hardener/scripts/hardener.py check --workspace

# Apply safe fixes (chmod/exec-bit cleanup + optionally openclaw audit --fix)
python3 skills_live/openclaw-hardener/scripts/hardener.py fix --all

# Generate a config.patch plan (prints JSON5 patch)
python3 skills_live/openclaw-hardener/scripts/hardener.py plan-config

# Apply the plan (requires a running gateway; uses `openclaw gateway call`)
python3 skills_live/openclaw-hardener/scripts/hardener.py apply-config
```

## Design rules (do not violate)

- **Default = check-only.** No file/config changes unless user runs `fix` or `apply-config`.
- **No secrets in output.** If a check reads sensitive paths, it must redact likely tokens.
- **Patch plans must be explicit.** Always show the patch before applying.

## What it checks / fixes

### OpenClaw built-in security audit
- Runs `openclaw security audit --deep` (and `--fix` in fix mode).

### Workspace hygiene (scope: workspace + ~/.openclaw)
- Permissions sanity under `~/.openclaw` (basic checks).
- Unexpected executable bits in non-executable filetypes.
- Stray `.env` files (warn) and tracked `.env` (fail).
- Risky deserialization / unsafe patterns in our scripts (heuristics).

### Config hardening (optional plan)
Generates a conservative `config.patch` template focusing on:
- Tightening inbound access defaults (pairing/allowlist, mention gating) **only if you opt-in**.
- Ensuring sensitive log redaction is enabled.

(Exact keys depend on your config; the plan is best-effort and should be reviewed.)
