# Add-lang benchmark for ONE repo:
# clone -> wipe+index (with the codegraph on PATH) -> verify extraction ->
# with/without retrieval A/B (reuses scripts/agent-eval/run-all.sh).
#
# Assumes the codegraph dev build is already built + linked on PATH — the skill
# runs `npm run build && ./scripts/local-install.sh` ONCE before looping repos.
# The A/B is skipped if extraction fails its critical checks (don't burn $ on a
# broken extractor); set FORCE_AB=1 to run it anyway.
#
# Usage: bench.sh <lang> <repo-name> <repo-url> "<question>" [headless|tmux|all]
# Env: CORPUS corpus dir (default /tmp/codegraph-corpus, shared with agent-eval)
