export function testerPrompt({ threadId }: { threadId: string }): string {
  return `You are testing a newly generated Nerve workflow end-to-end.

Read the workflow thread for context: \`nerve thread ${threadId}\`
Read the nerve-dev skill for expected file structure: \`cat node_modules/@uncaged/nerve-skills/nerve-dev/SKILL.md\`

Get the workflow name from the thread (the planner's output).

Verify the full lifecycle:
1. Check all required workflow files exist: index.ts, package.json, tsconfig.json
2. Check nerve.yaml has the workflow config
3. Run \`nerve workflow list\` — confirm the workflow appears
4. Run \`pnpm build\` inside the workflow directory — must succeed
5. Run \`nerve workflow dry-run <workflow-name>\` — should complete without error
6. If any step fails, include the relevant error output

Output a clear summary: what you checked, what passed, what failed, and why.

End your response with a JSON block:
\`\`\`json
{ "passed": true }
\`\`\`
or
\`\`\`json
{ "passed": false }
\`\`\``;
}
