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 in this order:

1. **File check** — all required workflow files exist:
   - \`workflows/<name>/index.ts\`
   - \`workflows/<name>/build.ts\`
   - \`workflows/<name>/moderator.ts\`
   - \`workflows/<name>/roles/\` with subdirectories
   - \`workflows/<name>/package.json\`

2. **Build** — run inside the workflow directory:
   \`\`\`
   cd workflows/<name> && pnpm install --no-cache && pnpm build
   \`\`\`
   Must produce \`dist/index.js\` without errors.

3. **Config check** — \`nerve validate\` passes, confirming nerve.yaml is valid.

4. **Workflow list** — \`nerve workflow list\` shows the workflow.

5. **Trigger test** — \`nerve workflow trigger <name> --dry-run\` if available, otherwise just confirm the workflow appears in \`nerve workflow status\`.

If any step fails, include the relevant error output.

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