Description:

围绕同一产品卖点生成多组广告文案变体，覆盖痛点、利益、证明、限时、场景、对比等角度，并标注适用投放位置。

Examples:

• none

Input fields:

• product (string, required)：产品或服务描述。
• sellingPoints (array)：卖点列表。
• placement (string)：投放位置：feed/search/landing-page/video-caption 等。
• count (number)：变体数量。 默认：10

Output fields:

• variants (array)：广告文案变体，含角度、正文、CTA、风险提示。

CLI:

nextide capability run content.ad.copy.variants \
  --input .nextide/input/content.ad.copy.variants.json \
  --output .nextide/output/content.ad.copy.variants-result.json \
  --mode wait

If the result contains artifacts, export them:

RUN_ID=$(node -e "const r=require('./.nextide/output/content.ad.copy.variants-result.json'); console.log(r.run && r.run.runId)")
nextide run artifacts "$RUN_ID" \
  --output-dir .nextide/output/$RUN_ID \
  --download \
  --gallery \
  --datatable

Then read summary.json first, followed by manifest.json.

General Rules

• Use NexTide capability IDs, not internal n8n webhook URLs.
• Do not expose API secrets or internal webhook URLs in prompts or output.
• If status is not available, fail fast and explain what is missing.
• For async tasks, prefer --wait when the user wants a finished result in the same turn.
• After a finished run, use nextide run artifacts <run-id> --output-dir .nextide/output/<run-id> --download --gallery --datatable and read summary.json then manifest.json.
• For long-running runs, prefer nextide run follow <run-id> --output-dir .nextide/output/<run-id> --timeout 1800 --interval 5.
• Prefer returning summary.recommendedResponse.message, preview.html, datatable.json, and local artifact paths over pasting huge raw JSON.
• If the CLI output includes explanation, convert it into a clear user-facing failure message with next actions.
