Continue a coding-agent session in a different agent. Continuo is a macOS menu-bar app that converts a recent Claude Code, Codex, or OpenCode session into another agent's native format and opens it already resumed in your chosen session destination — in any direction, on demand.
Switched tools mid-task? Hitting a model's limits? Want a fresh agent with the same context? Open the picker, pick a session, click the agent you want to continue in.
brew install --cask yoavf/tap/continuoOr download the latest Continuo.dmg from Releases, drag it to Applications, and launch it — it's signed and notarized.
Recent sessions from ~/.claude and ~/.codex show up automatically. Click the menu-bar icon, or press ⌥⌘S from anywhere, to see them.
- Pick a session from the menu-bar picker — the newest across all three tools, searchable.
- Choose where to continue it. Click a session to open the continue panel and pick one of the other two agents.
- Choose how much to carry over — the full transcript when it fits the target model's context, or a handoff brief (a structured summary plus your most recent exchanges) when it wouldn't.
- It opens resumed. Continuo writes the target's native session file and opens the resumed session in your chosen destination.
Settings lets you point at custom homes, pick target models per direction, choose where sessions open, and toggle the hotkey.
A session destination can be a conventional terminal or a workspace environment. Continuo currently supports:
- Terminal, iTerm2, and Ghostty — open the resumed agent directly in a new terminal session.
- CMUX — create a named workspace and run the resumed agent inside it. One-time password access must be enabled under CMUX → Settings → Automation.
Native session files are read-only inputs. Continuo only ever writes its own mirror files, tracked in bridge-state.json; it refuses to overwrite anything it doesn't own, and never rewrites a mirror you've since continued natively (it makes a fresh one instead). Nothing runs in the background — sessions are converted only when you ask.
Converting a transcript means translating each tool call into the target agent's vocabulary (Claude's Bash ⇄ Codex's exec_command, and so on) so transplanted history reads naturally. Model matching is conservative: the source model is preserved in metadata, and the converted session gets a target-provider model from built-in family matches or your Settings defaults. Hidden provider reasoning is never carried across * — only the visible conversation, tool summaries, and safe metadata.
When a session's title is just a raw prompt, and when it builds a handoff brief, Continuo uses your Mac's on-device model (Apple Intelligence, where available) to write a clean title or a custom compaction of the conversation. Nothing about your sessions is sent anywhere — the on-device model runs locally, and everything else is plain file conversion.
* The latest OpenAI and Anthropic reasoning models return their chain-of-thought as encrypted, provider-owned tokens that never appear in the readable transcript and can't be replayed into another provider. That reasoning is necessarily left behind when you continue a session elsewhere.
What carries over
- Your prompts and the agent's replies, in full
- Tool calls — name, input, and output — remapped to the target agent's equivalent operation
- Timestamps and session metadata: model, working directory, title
What stays behind
- Provider reasoning and thinking traces (encrypted and provider-owned — see above)
- Token counts and billing/usage data
- System prompts and other injected context (the target agent supplies its own)
- Raw file-history snapshots
OpenCode sessions are read from its opencode.db and written through the official opencode import command; models cross in with their provider prefix (anthropic/claude-…, openai/gpt-…) and cross out by stripping it.
Transfer budgets come from each model's real context limit, sourced from models.dev: a snapshot is bundled at build time and refreshed weekly at runtime, falling back to the bundle when offline.
- session-porter — a CLI for porting agent sessions between tools, if you'd rather work from the command line.
