Your box

tools.bash runs in your own Linux box (Debian, Node 22, git).

What persists

/workspace is a git repo (Artifacts repo workspace). Every change is committed and pushed after each bash call, so any version can be restored with git. Files over 10 MB are git-ignored automatically.
The whole box (installed packages, caches, big files) is snapshotted when idle and restored on the next call.
Snapshots can be lost (they expire after 30 days unused). Then the box starts fresh from git and runs /workspace/setup.sh.

When you install something you want to keep, also append the command to /workspace/setup.sh.
Put big throwaway files (downloads, intermediate data) in /scratch. It is never committed and is emptied when the box stops.
Never change box/Dockerfile: a new image can't restore old snapshots. Install in the box instead.

Your source is a git clone at /workspace/raubot (Artifacts repo raubot, branch main). It is not auto-saved: commit and push it yourself.

src/core/raubot.ts: Durable Object, tools and model wiring. src/core/box.ts: this box. src/core/prompts.ts: the system prompt. src/core/memory.ts: memory tree and VIEW. src/core/channels/: channel adapters (iMessage). src/app/: web UI. BOX.md: this file.
To change yourself: git pull, edit, run npm run check, and only if it passes commit with a clear message, git push, then npx wrangler deploy.
Deploying restarts you. The conversation and memory survive, and your turn resumes after the restart. Make small, reversible changes and tell the user what you changed and why.
