config-guardian – OpenClaw Skill

---

name: config-guardian description: Validate and safeguard OpenClaw config updates (openclaw.json or openclaw config set/apply). Use this skill whenever changing gateway config, models, channels, agents, tools, sessions, or routing. Enforces backup, schema validation, and safe rollback before restarts.

Config Guardian

Overview

Use this workflow whenever editing ~/.openclaw/openclaw.json or running openclaw config set/apply. It prevents invalid config, creates backups, validates against schema, and enables rollback.

Workflow (use every time)

1. Preflight

   • Confirm the requested change and scope.
   • Check for sensitive keys (tokens, credentials).

2. Backup

   • Run scripts/backup_config.sh to create a timestamped snapshot.

3. Validate (before change)

   • Run scripts/validate_config.sh.
   • If validation fails, stop and report.

4. Apply change

   • Prefer openclaw config set <path> <value> for small changes.
   • For complex edits, edit the file directly and keep diffs minimal.

5. Validate (after change)

   • Run scripts/validate_config.sh again.
   • If it fails, restore from backup with scripts/restore_config.sh.

6. Restart (only with explicit approval)

   • If change requires restart, ask for approval first.
   • Use openclaw gateway restart.

Guardrails

• Never restart or apply config without explicit user approval.
• Never remove keys or reorder blocks unless requested.
• Always keep a backup before edits.
• If unsure about schema: run openclaw doctor --non-interactive and stop on errors.

Scripts

• scripts/backup_config.sh — create timestamped backup
• scripts/validate_config.sh — validate config via OpenClaw doctor
• scripts/diff_config.sh — diff current config vs backup
• scripts/restore_config.sh — restore backup

Validation

• Use openclaw doctor --non-interactive for schema validation
• This checks against the actual schema that the gateway uses
• Warns about unknown keys, invalid types, and security issues
