powerfailureresumer restores interrupted coding-agent sessions
After a series of brief power outages broke his local agent sessions on macOS, the author built powerfailureresumer (pfr) to automate the recovery process.
What it does
- Detects the cluster of sessions that died during the outage.
- Reconstructs which projects were active and where they were running.
- Reopens each session in the right Ghostty tab.
- Resumes the correct tool/model settings, including the original model and effort level.
Why it’s useful
The post frames pfr as a recovery tool for people running multiple local coding agents such as Codex CLI and Claude Code. Instead of manually reconnecting every session after a reboot or power loss, the tool turns the process into a single automated flow.
The screenshots show the installer, session scanning, confidence scoring, and successful restoration of multiple tabs.
