# safeclaude-base — the shared base every project builds on. Keep this generic:
# project-specific packages and language versions go in each project's own
# .safeclaude/Dockerfile (which starts with `FROM safeclaude-base`), not here.
#
# This image runs as root so project Dockerfiles can install system packages
# freely. Don't worry — the launcher locks things down at run time (normal user,
# no special privileges), so nothing Claude does actually runs as root.
#
# Debian (slim) as the base: small, stable, and its apt packages behave
# predictably in a container — notably `chromium` is a real package here, unlike
# on Ubuntu where it's a snap stub that won't run in a container.
FROM debian:bookworm-slim

# Just the basics every project needs:
#   - curl/ca-certificates: for downloads (the Claude installer, git-spice)
#   - git + ripgrep: required by Claude Code
# We leave apt's package lists in place (no cleanup) so a project Dockerfile can
# install packages without re-fetching them — though it should still run its own
# `apt-get update` first, since this base image may be days or weeks old.

# keep the host's ownership, so the container can only write them if it runs as
# that same ID. It also means files Claude creates come out owned by you on the
# host — not root or some stray ID. The launcher rebuilds this image if the host
# ID ever changes (it reads the labels below to notice), so the default here is
# just a placeholder for a from-scratch build.
