load_env.sh

# Load the env files into the calling shell by parsing them, never by running
# them (#170). Source me from the repo root, in the same command as whatever
# needs the variables - an agent's tool starts a fresh shell per call:
#
#   . scripts/load_env.sh; . scripts/rcli.sh; rcli PING
#
# Sourcing an env file runs it as shell code, so a `$(...)` or a backtick in a
# value executes, and the repo .env holds org-wide PATs. load_env reads plain
# KEY=value lines (an optional `export `, matched quotes) and exports each one.
# It still exports, so whatever either file holds reaches every child process:
# keep secrets a shell has no use for out of both.
#
# load_env is lifted in place from the vendored recipe in the header of
# skills/shipping-work/scripts/pre-ship.sh, which stays the only
# copy; init-project-fastapi's template lifts it with the same sed line.
#
# Order: /etc/replicator/.env, then the checkout's .env, so the developer's file
# wins. A linked worktree has no .env (it is git-ignored), so it falls back to
# the primary checkout's, as the recipe does. A missing file loads nothing.
#
# Everything runs inside one function so the caller's shell keeps no name of
# ours but load_env and what the files set. Bash only: it reads BASH_SOURCE.
