# usage: tools/author/launch_agy.sh <job_dir>   Gemini 4 Argon twin of launch.sh (15 Oct 2026, operator: "a mix with Astra and
# Gemini 4 through AGY"): same job.json, same PROMPT.txt, run by Google's Antigravity CLI (~/bin/agy4, Vertex = Google grant).
# agy diffs every untracked file of the git repo it starts in, so the job runs in a scratch copy outside git
# (/tmp/agy-author/<job>) and its deliverables are copied back; node_modules and caches stay behind.
# Writes started.txt, finished.txt, rc.txt, astra.log (the agent's output, same name as the Astra lane so the loops work)
# and agy-relay.log (one line per model call: the usage record, tools: ~/forge-hub/agent/agy4_cost.py).
