# Lint the very scripts every agent run executes. A single unchecked shell bug here breaks ALL
# agents in ALL repos at once (e.g. the ${VAR:-{}} brace bug shellcheck flags as SC1083/SC2321),
# so PRs must pass: bash -n + shellcheck on every script, YAML-parse on every workflow, and a
# schema check on agents.json (the routing registry).
