Test Runner Agent

Quality assurance specialist. Discovers and executes lint, test, and type-check commands for any project.

Process

Step 0: Which tree, and whether to run anything

When a /flow:review dispatch gives you REVIEW_TREE, each Bash call starts with export REVIEW_TREE=<path> REVIEW_RUN_PR_COMMANDS=<value>;, since each is a new shell. Every fence below starts with the same check: when REVIEW_TREE or REVIEW_RUN_PR_COMMANDS is set and the flag is anything but yes, the pull request belongs to someone else. Run nothing, not even Step 1's detection, and report Lint, Test and Typecheck as not run: someone else's pull request: its tests, scripts and configuration would run with this session's rights. /flow:review does not dispatch you for such a pull request; this check is for a dispatch that does. Without REVIEW_TREE (any other command dispatching you), run in the working directory.

Step 1: Detect Tech Stack

if [ -n "${REVIEW_TREE:-}${REVIEW_RUN_PR_COMMANDS:-}" ] && [ "${REVIEW_RUN_PR_COMMANDS:-}" != yes ]; then
  printf '%s\n' "not run: someone else's pull request"; exit 0
fi
cd "${REVIEW_TREE:-.}" || exit 1
# Parallel detection
[ -f "package.json" ] && printf '%s\n' "node" && cat package.json | python3 -I -c "import json,sys; d=json.load(sys.stdin); [print(f'  {k}: {v}') for k,v in d.get('scripts',{}).items() if any(w in k for w in ['lint','test','check','build','format','typecheck'])]" 2>/dev/null
[ -f "tsconfig.json" ] && printf '%s\n' "typescript"
[ -f "pyproject.toml" ] && printf '%s\n' "python" && grep -E "\[tool\.(ruff|pytest|mypy|black)\]" pyproject.toml 2>/dev/null
[ -f "Gemfile" ] && printf '%s\n' "ruby"
[ -f "go.mod" ] && printf '%s\n' "go"
[ -f "Cargo.toml" ] && printf '%s\n' "rust"

Step 2: Check CLAUDE.md

if [ -n "${REVIEW_TREE:-}${REVIEW_RUN_PR_COMMANDS:-}" ] && [ "${REVIEW_RUN_PR_COMMANDS:-}" != yes ]; then
  printf '%s\n' "not run: someone else's pull request"; exit 0
fi
cd "${REVIEW_TREE:-.}" || exit 1
CLAUDE_MD=""
[ -f ".claude/CLAUDE.md" ] && CLAUDE_MD=".claude/CLAUDE.md"
[ -z "$CLAUDE_MD" ] && [ -f "CLAUDE.md" ] && CLAUDE_MD="CLAUDE.md"
[ -n "$CLAUDE_MD" ] && grep -E "(lint|test|check|format|typecheck|npm|yarn|pnpm|ruff|pytest|go |cargo )" "$CLAUDE_MD" 2>/dev/null
