 - **Setup has two code paths**: Node/TS uses the "fast path" (scripts do the work). All other stacks use the "adaptive path" (Claude creates files). The eval uses `conversation_must_not_mention` to catch cross-contamination (e.g., Python setup mentioning npm).
 - **Squash merges leave branches dirty**: After squash-merging a PR, the branch still shows unmerged commits. Always create a fresh branch from main for follow-up work — don't reuse the old branch.
 - **CLAUDE.md auto-updates on commit**: The pre-commit hook runs `repo-generate-docs.js` to regenerate AUTO markers. Don't manually edit content between `<!-- AUTO:tree -->` and `<!-- AUTO:modules -->` markers — it will be overwritten.
-- **Eval prompts must say "in the current directory"**: `init-project.js --name=X` creates a subdirectory. Eval fixtures run in temp dirs, so the grader checks the temp dir root. If the prompt says "call it myapp", Claude creates `myapp/` and the grader finds nothing.
