Maintain Environment

Scope

• Single reproducible development environment.
• Definition files: .devcontainer/Dockerfile, .devcontainer/devcontainer.json, scripts/devcontainer-post-create.sh, ai-forecasting-hackathon.code-workspace.

Change policy

• Environment changes require project owner approval and a devcontainer rebuild.
• Modify definition files directly, not ad-hoc local installs, to keep reproducibility and documentation.

Available tools

• Base image: mcr.microsoft.com/devcontainers/base:ubuntu
• Node and npm
• Common CLIs: git, gh, rg, jq, fd, curl, tree, inotifywait, entr
• IDE for project owner: code-tunnel

Host binds and worktrees

• Host binds are defined in devcontainer.json and must exist or rebuilds fail.
• Host binds persist caches, oauth tokens, and configs across rebuilds.
• Worktrees persist in /workspaces/worktrees/.
• Shared across worktrees: host binds and /workspaces/worktrees/shared/.

Notes

• Toolchain usage is documented in package-level docs.
• All agents and the project owner use the same devcontainer on the same ubuntu 24.04 host OS.
• No other clones of the repo exist, so gitignored changes and caches persist unless removed during worktree removal.
