# Headless Claude Code run against a repo with codegraph MCP, capturing the

# full stream-json so we can see tool calls + token usage. Complements the

# interactive itrun.sh: headless gives a clean per-tool breakdown + exact

# tokens/cost, but defaults to the general-purpose subagent (not Explore).

# To force the Explore path, ask for it in the prompt.

#

# Usage: run-agent.sh <repo-path> <label> "<prompt>"

# Env: AGENT_EVAL_OUT (default /tmp/agent-eval), CG_BIN (codegraph dist binary)
