name: bupt-empty-classroom description: Query empty classrooms at BUPT (Beijing University of Posts and Telecommunications) Xitucheng campus.

BUPT Empty Classroom Query

This skill queries the BUPT empty classroom system at https://ec.jray.xyz/

Workflow

Step 1: Open the website

Use agent-browser to open the URL:

agent-browser open https://ec.jray.xyz/

Step 2: Verify campus selection

• The page defaults to "西土城" (Xitucheng) campus
• Verify it's selected (look for [checked] on radio "西土城")
• If not, click on it: agent-browser click @e2

Step 3: Select building

Click on the building button:

• 教2: agent-browser click @e6
• 教3: agent-browser click @e7
• 教4: agent-browser click @e8
• 未来学习大楼: agent-browser click @e9

Step 4: Select time period

After clicking the building, the time period buttons will appear. Each button shows the format: HH:MM 节次 HH:MM

Example buttons:

• 08:00 01 08:45 (第1节)
• 08:50 02 09:35 (第2节)
• ...and so on

Click on the desired time period button (check refs from snapshot).

Step 5: Extract results

After selecting the time period, the page will show a table with empty classrooms:

Column	Description
教室	Classroom ID (e.g., 教4-203)
座位数	Number of seats
类型	Room type (if available)
来源	Data source (usually "教务")

Use agent-browser snapshot or agent-browser snapshot -i to get the full table.

Example Session

# Step 1: Open website
agent-browser open https://ec.jray.xyz/

# Step 2: Get initial snapshot to see refs
agent-browser snapshot -i

# Step 3: Click on building (e.g., 教4)
agent-browser click @e8

# Step 4: Get updated snapshot
agent-browser snapshot -i

# Step 5: Click on time period (e.g., 17:25 11 18:10)
agent-browser click @e20

# Step 6: Get final results
agent-browser snapshot

Common Issues

1. Button refs change after each navigation: Always re-run snapshot after clicking a building or time period.

2. Some time periods are disabled: Passed time periods show [disabled] and cannot be clicked.

3. No empty classrooms: If no classrooms are shown after selecting a time period, it means all classrooms are occupied at that time.

Notes

• The website defaults to current date
• Only Xitucheng campus is fully supported (沙河 campus can be selected but workflow is same)
• Data source is usually the university's academic system (教务)
