Hit Claude limits? Don't feel defeated. I built a small CLI tool to seamlessly resume your AI coding sessions in Copilot or Codex: resume-cli.
The problem: usage limits in the middle of a session
If you work with AI coding agents all day, you know the moment. You are deep into a session, the agent has all the context, and you hit your usage limit. Starting over in another tool means explaining everything again.
resume-cli removes that friction.
What resume-cli does
It is an interactive terminal UI that lists your recent sessions from Claude Code, Codex and Copilot in one place. You select a session, choose which tool to continue in, and you're back to work.
▶ Claude Code Apr 07 14:32 2h ago refactor the auth middleware
Copilot Apr 07 11:05 5h ago add pagination to the API
Codex Apr 06 09:14 1d ago fix the flaky test in parser
Continue in: ◀ Claude Code ▶ ↑↓ navigate · tab: switch tool · ↵ launch · q quit
Use the arrow keys to pick a session, Tab to cycle the target tool, Enter to launch, and q or Esc to quit. Only tools installed on your machine show up.
How it works
Sessions are read directly from each tool's local storage:
| Tool | Session directory |
|---|
| Claude Code | ~/.claude/projects/ |
| Codex | ~/.codex/sessions/ |
| Copilot | ~/.copilot/session-state/ |
Same-tool resume uses the tool's native --resume <uuid> flag. No data is copied or converted.
Cross-tool resume starts the target tool with an initial message pointing to the original session file. The AI reads it and continues from where you left off, with the full conversation history as context.
Install
The quickest way: ask your AI agent to install it for you.
Or add a resume function to your shell profile. For bash, in ~/.bashrc:
resume() {
local cmd
cmd=$(FORCE_COLOR=3 npx -y ai-resume-cli@latest)
[ $? -eq 0 ] && [ -n "$cmd" ] && eval "$cmd"
}
Reload your shell and type resume from anywhere. The README also has versions for zsh, fish and PowerShell. You need Node.js 18+ and at least one of Claude Code, Codex or Copilot CLI. It runs on macOS, Linux and Windows.
Have fun!
