What happens if I import the same sessions twice?

Nothing is duplicated. Identical chats are kept as-is; changed chats you have not touched in idapt are updated in place; changed chats you touched are left alone.

Which OpenCode versions are supported?

The 2.0.x session database (opencode.db) imports. Subagent sessions are skipped with a visible count.

Bring your OpenCode chats

One command reads OpenCode's session database and imports them with dates and tool calls: `idapt chat import --from opencode`.

How to migrate

1
Install the CLI
One global install; the same CLI the quickstarts use.
```
npm i -g @idapt/cli
```
```
npm i -g @idapt/cli
```
2
Import your chats
Run the importer. It signs you in if needed (browser), opens the session database read-only (XDG data dir), and previews what will be imported. Default scope: sessions started in the current directory; use --all for every project on the machine.
```
idapt chat import --from opencode
```
```
idapt chat import --from opencode
```
3
Keep OpenCode while you evaluate
Point OpenCode at idapt's endpoint and compare on your real workload before you switch fully.
