resume-from: Open-Source Tool for Seamless Session Handoffs Between AI Coding Agents
alexei_led · reddit · 2026-08-07
Developers frequently face context loss when switching between terminal AI coding agents like Pi, Claude Code, and Codex. To solve this, the author open-sourced resume-from, a local session handoff tool.
Core features include:
- Format conversion: Automatically detects sessions in the current Git repo, converts the source format into a common conversation model, and writes it into the target agent’s native format.
- Safe pruning: Retains user prompts, replies, and changed file paths, but strips out tool results, hidden reasoning, system prompts, and API keys.
- Local and deterministic: The entire conversion runs locally without calling a model, and writes nothing until the user confirms.
This tool addresses the problem of rebuilding task context from scratch due to incompatible session formats across different AI tools.
