PaaS Automation Agents

SI includes two sustainable automation agents for long-running operational loops:
  • PR Guardian: pull request triage and safe autofix lanes.
  • Website Sentry: continuous repo/runtime health checks with remediation attempts.

​
Layout

  • tools/agents/config.sh: runtime defaults and policy thresholds.
  • tools/agents/lib.sh: logging, locks, retries, summary/finalization helpers.
  • tools/agents/pr-guardian.sh: PR risk triage and bounded autofix.
  • tools/agents/website-sentry.sh: health checks and remediation loop.
  • tools/agents/doctor.sh: preflight and syntax validation.
  • tools/agents/status.sh: latest-run summaries.

​
Reliability Patterns

  • Deterministic run artifacts (summary.md, run.log, run.jsonl) per run.
  • Filesystem lock guards to prevent overlapping runs.
  • Retry policy with exponential backoff for transient failures.
  • Workflow-level concurrency guards in GitHub Actions.

​
Workflows

  • .github/workflows/agent_pr_guardian.yml
  • .github/workflows/agent_website_sentry.yml
Artifacts are stored under .artifacts/agent-logs/.

​
Local Operations

bash tools/agents/doctor.sh
bash tools/agents/status.sh
bash tools/agents/pr-guardian.sh
bash tools/agents/website-sentry.sh

​
Notes

  • pr-guardian only pushes autofixes on same-repo pull request events.
  • website-sentry runs SI test workflows and attempts safe formatting remediation.
