Safe VPS Releases
Example session with this skill installed
Deploy the new auth fix to the production VPS. Use the Docker Compose flow and run the test gate first.
- Read your context and instructions
- Compiled the safe vps releases
I have prepared the deployment for the authentication fix. I verified the server state and identified three files for the release.
Deployment Analysis & Candidate Build
| Phase | Status | Details |
|---|---|---|
| Fingerprinting | PASSED | Current production matches expected MD5 hashes. |
| Candidate Build | PASSED | Image app:candidate-auth-fix built and started on port 8080. |
| Health Check | PASSED | Candidate responded with 200 OK at /health. |
| Test Gate | PASSED | 0 new failures. 1 failure fixed (Auth-Token-Expiry). |
Test Results Comparison
- Production (Base): 124 passed, 3 failed, 0 errors.
- Candidate (Change): 125 passed, 2 failed, 0 errors.
- Delta: No new regressions detected. The candidate resolves
tests/auth_test.py::test_token_refresh.
Rollback Plan
The current running image app:latest (ID: a1b2c3d4) has been tagged as app:before-auth-fix. A rollback can be triggered by re-tagging and restarting if the switch fails.
Next steps
- Review the test delta report above to ensure the fix coverage is sufficient.
- Provide an explicit "go" to execute
activate.shand switch the production traffic. - Monitor the public logs for 5 minutes post-switch to confirm stable operation.

About this skill
Deploy to your own server without ever breaking production.
Deploy changes to a single production VPS (Docker Compose or a systemd service with git) without breaking it - build a candidate next to the running service, gate it on "zero NEW test failures" against the current production, switch over with health checks, and roll back automatically. Use when the user wants to deploy, release, ship a hotfix, or roll back on their own server, or when a previous deploy broke production.
Includes an EXPERT.md reference (exact parameters, thresholds, failure diagnosis). Tested scripts: scripts/activate.sh, scripts/build-candidate.sh, scripts/compare_failures.py, scripts/git-safe-deploy.sh.
