openclaw-hardener – OpenClaw Skill

name: openclaw-hardener description: "Harden OpenClaw (workspace + ~/.openclaw): run openclaw security audit, catch prompt-injection/exfil risks, scan for secrets, and apply safe fixes (chmod/exec-bit cleanup). Includes optional config.patch planning to reduce attack surface."

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:

# 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.)
