Code Generation with Claude Code

Your team uses agent teams in Claude Code to parallelize a large code generation workflow. After several sprints, developers report that teammates frequently go idle before the build pipeline has validated their output — leaving incomplete artifacts in the dist/ directory that block downstream teammates. You add a TeammateIdle hook to enforce a build check. What is the most effective way to configure the hook so that a teammate with a missing dist/output.js artifact is redirected to fix its output rather than going idle?

A. Return JSON {"continue": false, "stopReason": "Build artifact missing"} so the user is notified and the teammate terminates cleanly.

B. Emit a warning message to stdout and exit with code 0, allowing the teammate to proceed to idle but logging the issue for later review.

C. Write the failure message to stderr and exit with code 2, which delivers the feedback to the teammate and causes it to continue working instead of going idle.

D. Register a PostToolUse hook instead, so each build tool invocation checks for dist/output.js and re-runs the build step if the artifact is absent.
