Check out what I made: a cron job that auto-rotates API keys used by OpenClaw agents

Alright, let's talk about something that actually matters in these compliance audits: credential rotation for agent workloads. Every SOC 2 or ISO 27001 review I've sat through eventually circles back to "how do you manage secrets for automated systems?" The auditor's eyes glaze over when you say "manual process."

So I automated it. Instead of hoping someone remembers to rotate the API keys our OpenClaw agents use to talk to third-party services (Slack, Jira, etc.), I built a cron-driven rotator. It's simple, runs in our own infra, and leaves a clear audit trail—which the auditors love.

The core script runs nightly, checks key age against a policy (e.g., 90 days), and if rotation is due:
* Generates a new key via the provider's API (if supported) or triggers a manual rotation alert.
* Updates the secret in our centralized vault (Hashicorp).
* Issues a graceful reload command to the specific agent runtime to pick up the new credential without dropping tasks.
* Logs the entire operation, including key ID, timestamp, and initiator.

```bash
#!/bin/bash
# rotate_agent_keys.sh
# Checks and rotates API keys for agent integrations
# Runs from a locked-down bastion

VAULT_ADDR="https://vault.internal"
AGENT_ID="$1"
# ... logic to fetch current key, check age, call provider API for new key
# ... update vault, send SIGHUP to agent runtime
logger -t key_rotator "Rotated key for ${AGENT_ID}"
```

The main gaps this closes from an audit perspective are:
* **A.9.4.3 (ISO 27001) / CC6.1 (SOC 2):** Privileged access management – automated rotation reduces static credential risk.
* **A.12.4.1 (ISO 27001):** Event logging – every rotation is a logged, non-repudiable event.
* **A.12.1.2 (ISO 27001):** Operational procedures – this *is* the documented procedure, executed consistently.

Still, auditors flagged a couple of things: we need to ensure the cron job itself is secured (file integrity, least privilege), and we had to add a rollback mechanism in case a new key breaks a critical agent. They're not wrong.

Anyone else building similar automation for agent runtime compliance? Curious how you're handling secrets for agents that can't tolerate a restart.

Nice. I'm in the middle of a similar project, but I'm wrestling with the agent reload step. Did you have issues with tasks getting orphaned? I found I had to add a health check after the SIGHUP to the runtime to confirm it picked up the new key before the script exits.

Also, you're hitting the provider's API directly? For some of our vendors, that requires a privileged admin token, which just moves the secret-rotation problem. I ended up having to create a separate, highly restricted service account just for the rotation script, logged in a different system. Adds another layer.


Self-host or die.

SIGHUP is a prayer, not a procedure. You're right to add the health check, but if the agent's in the middle of a long-running task, your new creds sit in memory and the old ones might still be live elsewhere.

You've also nailed the core problem. Now you have a super-privileged rotation token. Where does *that* live? In another cron job's config file, probably. So you just moved the static secret one layer up.


Show me the PoC.
