Game Activity Extractor
Extract game version activity information from announcement articles (URLs or images) and output structured JSON.
When to Invoke
- User provides a URL (e.g., miyoushe.com, bilibili.com) or an uploaded image containing a game version update announcement
- User asks to extract version activity information / 活动信息 from an article or image
- User asks to output game activity data in JSON format
Workflow Steps
Step 1: Fetch Source Content
- If the input is a URL: Use
WebFetch to retrieve the article content.
- If the input is an uploaded image: Use
Read with the image file path to extract all visible text (activity names, date ranges, reward amounts, category labels, etc.).
Step 2: Identify Version-Level Information
Extract or infer the following version-level fields:
| Field | Description | How to Determine |
|---|
version | Version number (e.g., "4.4", "3.5") | Usually stated in the article title or header |
versionName | Version subtitle/name (e.g., "鸣笛于归寂之时") | Usually in quotes in the article title |
startTime | Version start time (ISO 8601) | Maintenance/update start time stated in the article |
endTime | Version end time (ISO 8601) | Explicitly stated, or inferred from version cycle (~42 days) |
cover | Version cover image URL | Leave empty string "" if not available |
Step 3: Identify Activities to Include
Include the following types of activities:
- Version limited-time events (版本限时活动)
- Sign-in events (签到活动)
- Combat/challenge events (战斗挑战活动)
- Exploration events (区域探索活动)
- Version-rotating challenges (版本轮换挑战)
Exclude the following types of content:
- 网页活动 (Web/H5 events) — explicitly labeled as web events
- 角色卡池/祈愿/唤取/棋盘 (Character banners/gacha)
- 武器卡池/弧盘研募 (Weapon banners/gacha)
- 永久开放内容 (Permanently available content — story quests, new regions, permanent game modes)
- 商城上架内容 (Shop items — costumes, vehicles, houses)
- 补偿邮件 (Compensation mail)
- 版本更新公告本身 (The version update notice itself)
- 新手活动 (New player activities, unless they are version-limited)
Preserve ongoing activities from previous versions: When updating an existing game's JSON file, check the previous version's activities. If any activity's endTime is after the new version's startTime, that activity is still ongoing and must be kept in the updated JSON, even if the new version introduces a replacement activity of the same type.
Step 4: Extract Activity-Level Fields
For each included activity, extract:
| Field | Description | How to Determine |
|---|
name | Activity name | Use exact text from the article, including special characters like 「」・· |
description | Activity description | Use the descriptive text from the article. If no description is provided, summarize the activity purpose in one sentence. |
startTime | Activity start time (ISO 8601) | See "Time Format Rules" below |
endTime | Activity end time (ISO 8601) | See "Time Format Rules" below |
cover | Activity cover image URL | Leave empty string "" if not available |
Step 5: Time Format Rules
General rules:
- All times must be in ISO 8601 format:
YYYY-MM-DDTHH:mm:ss
- All times are in Asia/Shanghai timezone (UTC+8) unless the article specifies otherwise
- The article usually states times as "服务器时间" (server time), which defaults to UTC+8
- End times must use the last second of the minute (e.g.,
03:59:59 instead of 03:59:00).
Converting relative time references:
| Article Text | How to Convert |
|---|
| "X版本更新后" | Use the version maintenance completion time (e.g., if maintenance is 06:00-11:00, use 11:00:00) |
| "X版本结束（前）" | Use the version end time |
| "永久开放" | Exclude this activity — it's not a limited-time event |
| "Y版本结束前" (references a future version) | Search the web for that version's end date, then use it. If not found, note it as an estimate. |
| "活动期间" with no dates | If version-period aligned, use version start/end. If no dates at all, note it in the explanation. |
Common game time conventions:
| Game | Daily Reset | Version Update Time | Version End Time |
|---|
| Genshin Impact (原神) | 04:00 | ~06:00 after maintenance | ~06:00 next version |
| Honkai: Star Rail (崩坏：星穹铁道) | 04:00 | ~06:00 after maintenance | ~06:00 next version |
| Zenless Zone Zero (绝区零) | 04:00 | ~06:00-11:00 after maintenance | ~06:00 next version |
| Wuthering Waves (鸣潮) | 04:00 | ~04:00-11:00 after maintenance | ~03:59 next version |
| Neverness To Eeverness (异环) | 05:00 | ~06:00-11:00 after maintenance | ~05:59 next version |
Step 6: Output JSON
Output the final result as a JSON code block with the following structure:
{
"version": "X.X",
"versionName": "版本副标题",
"startTime": "YYYY-MM-DDTHH:mm:ss",
"endTime": "YYYY-MM-DDTHH:mm:ss",
"cover": "",
"activities": [
{
"name": "活动名称",
"description": "活动描述",
"startTime": "YYYY-MM-DDTHH:mm:ss",
"endTime": "YYYY-MM-DDTHH:mm:ss",
"cover": ""
}
]
}
Step 7: Provide Explanations
After the JSON output, provide a brief 说明 (explanation) section covering:
- Version time: How the version start/end times were determined
- Excluded items: List what was excluded and why (e.g., web events, gacha, permanent content)
- Time notes: Explain any time assumptions or conversions made (e.g., "3.5版本更新后" was converted to 11:00 as the maintenance completion time)
- Estimated dates: If any dates were estimated (e.g., referencing a future version's end date), note that the actual date should be confirmed with official announcements
Additional Rules
- Language matching: All output (JSON values, descriptions, explanations) must be in the same language as the source article (typically Chinese for miyoushe.com/bilibili.com articles).
- Description text: Use the article's original descriptive text verbatim when available. If the article doesn't provide a description, write a concise one-sentence summary.
- Cover field: Leave as empty string
"" unless a specific cover image URL is available for that activity.
- Ordering: List activities in chronological order by start time.
- No fabrication: Do not invent dates, times, or descriptions not present in or reasonably inferable from the source material. If information is missing, note it in the explanation.
