# The official image ships no agent CLIs or language toolchains. Add them here,
# one concern per layer, cheapest and least-changing first.

# Stays root: the entrypoint needs root to chown the mounted volumes, then
# drops to paseo with gosu itself. Nothing installs into $HOME -- that is
# /home/paseo, a volume mount that masks anything baked in at build time.

# --- system packages -------------------------------------------------------
# Everyday shell tooling. git and curl are already in the base image; sudo is
# not, despite Debian's base-passwd shipping an (empty) sudo group.
#
# build-essential is the C toolchain the language layers below assume but do
# not ship: cgo, npm's node-gyp addons and Python C extensions all shell out to
# gcc and make. Kept in this layer so there is only one apt-get update.

# --- python ----------------------------------------------------------------
# Debian 12 only carries 3.11, so fetch a standalone CPython build with uv
# (astral.sh/uv). Both directories sit outside $HOME.

# --- bun -------------------------------------------------------------------
# Only omp needs it: @oh-my-pi/pi-coding-agent is Bun-compiled and its bin
# opens with `#!/usr/bin/env bun`, so without Bun on PATH npm installs an omp
# that cannot start. BUN_INSTALL lands it in /usr/local, not the $HOME/.bun
# default that the paseo-home volume would mask.

# --- agent CLIs ------------------------------------------------------------
# These all publish the same way: a thin launcher plus the real binary as a
# per-platform optional dependency. npm therefore installs exactly what each
# vendor's own installer would, and is not a Node wrapper.
#
# Do not swap any of them for their `curl | bash` installer -- those write to
# $HOME/.local, and $HOME is /home/paseo, a volume that masks whatever the
# build put there. Last because these change most often.

# --- entrypoint ------------------------------------------------------------

# root -- see entrypoint.sh. tini stays in front of it, as in the base image.
# Last so that editing the script rebuilds only this layer.
