MCP.Pizza Chef: Kaseban

baton lets you switch your AI coding sessions between popular coding assistants like Claude Code, OpenCode, Codex, Gemini CLI, Cursor, and more. Instead of starting over when you hit limits or want a second opinion, baton converts your session so you can pick up exactly where you left off in another app. It works locally, requires no API keys, and can be installed easily with a simple command. Compatible with VS Code and other editors, baton keeps your coding conversations in sync and saves you time.

baton converting a Claude Code session to opencode

A passed transcript kept 14/17 concrete facts. A hand-written handoff summary kept 3/17. Benchmark ↓

The 4 p.m. problem

It's 4 p.m. Claude Code says "usage limit reached — resets at 10 p.m." You're three hours into a session: architecture decided, edge cases mapped, half the diff written.

❌ Without baton — open another agent and start from zero. Re-explain the plan. Re-read the files. Re-litigate every decision you already made.

✅ With baton — pass the session and keep going:

baton convert --from claude-code --to opencode --latest --import
# using latest claude-code session: 2026-07-09 15:58  Refactor the auth middleware to…
# passed baton: claude-code → opencode (1388 messages) → handoff.json
# Imported session: ses_8c4c973a521549e2

opencode -s ses_8c4c973a521549e2   # same conversation, different runner

Works in every direction: switch agents mid-task, try a second opinion on a hard bug, move a session from your editor agent to a terminal agent, or archive everything in one format.

Quick start

# zero-install run (downloads prebuilt binary)
npx @kasabeh/baton-mcp --help

# convert your most recent session + auto-import into the target agent
baton convert --from claude-code --to opencode --latest --import

# or omit the path to pick interactively — newest first,
# each session previewed by its first user message
baton convert --from claude-code --to opencode --import

# or pass an explicit session file
baton convert --from claude-code --to opencode <session.jsonl> --import

# see every session on your machine, across all agents
