Tooling to measure how a Claude Code agent actually uses the codegraph MCP tools on a real repo — does it lead with codegraph_explore, how many Read/Grep follow-ups, token cost — for validating tool-guidance changes (server-instructions, tool descriptions) against real agent behavior. - itrun.sh drives the real interactive TUI via tmux (the faithful Explore path). Hardened for unattended runs: type-and-verify prompt delivery (the ❯ glyph is drawn ~6s before the input accepts keys), auto-accepts the "trust this folder" dialog, busy-detection keys on the universal "(Ns · …)" spinner so the pre-stream thinking phase counts as busy, and fails loudly instead of capturing an empty pane. - parse-session.mjs reports the tool breakdown + token accounting (gen / fresh-in / cached-in / billable) from the session and subagent logs, consistent across main-thread and subagent runs; counts main-thread Bash in the grep verdict. - run-agent.sh / parse-run.mjs are the headless stream-json complement (exact per-tool tokens/cost via claude -p). - run-interactive-test.md documents how to run it and how completion is detected.

# 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.
