Feishu Sheet Tabs

Use this skill to add worksheet tabs inside an existing Feishu sheet by browser automation when feishu_sheet API can create/read/write spreadsheets but cannot create worksheet tabs.

Core conclusion

Current feishu_sheet API supports spreadsheet-level actions like:

• - create
• info
• read
• write
• append
• find
• export

It can target an existing sheet via sheet_id, but it does not expose a direct action for creating worksheet tabs/pages.

When the user explicitly wants tabs/pages inside one spreadsheet, switch to browser automation.

Preconditions

Before using browser automation, ensure all of the following:

1. 1. The target spreadsheet URL/token is known.
2. The user is logged into Feishu in a browser tab.
3. Prefer using the user's real Chrome tab via Browser Relay when available.
4. If Browser Relay is not attached, isolated browser may work only if it has a valid Feishu login state.

Preferred operating mode

Mode A: User's Chrome tab (preferred)

Use browser with profile="chrome" if the user has attached the tab via OpenClaw Browser Relay.

Why:

• - stable login state
• real user session
• fewer auth surprises

Mode B: OpenClaw managed browser

Use profile="openclaw" only if it is already logged into Feishu.

Reliable workflow

Step 1: Verify API limitation first

Do not claim “can’t do it” without checking.

Confirm from tool docs / current tool signature that feishu_sheet has no add_sheet / create_worksheet / add_tab action.

Step 2: Open the spreadsheet in browser

Use browser automation to open the spreadsheet.

Step 3: Inspect runtime objects

Feishu Sheets exposes internal JS objects on the page. In practice, these were found useful:

• - INLINECODE10
• INLINECODE11

Relevant methods discovered from runtime introspection:

• - INLINECODE12
• INLINECODE13
• INLINECODE14
• INLINECODE15
• INLINECODE16

Step 4: Read current sheet ids/names

Use page evaluation to inspect current sheets before mutation.

Pattern:

CODEBLOCK0

Step 5: Rename default first tab if needed

Typical pattern:

• - rename Sheet1 → INLINECODE18

Step 6: Add tabs with spread.addSheet(name)

For example:

• - Skills
• Workflows
• Templates
• Content

Step 7: Fill each tab with feishu_sheet write

After tabs exist and their sheet_ids are known, return to feishu_sheet for structured writes. This is more stable than trying to type cell-by-cell in browser automation.

Proven pattern from this workspace

For spreadsheet:

• - INLINECODE23

The following sequence worked:

1. 1. Inspect INLINECODE24
2. Discover spread.addSheet and INLINECODE26
3. Read current sheet list and ids
4. Rename Sheet1 to INLINECODE28
5. Create:

- Skills - Workflows - Templates - Content

1. 6. Use feishu_sheet write with returned sheet ids to populate each tab

Important caveats

1. 1. Prefer internal methods over brittle UI clicking

Clicking + in the UI was less reliable than runtime JS calls.

1. 2. Do not assume a visible plus button is the right entry

In this case, one nearby button turned out to be a template entry, not “new tab”.

1. 3. Use browser only for the tab creation step

Once tabs are created, switch back to feishu_sheet write.

1. 4. Inspect current ids before writing

New tabs get generated sheet_ids such as GxGIGa, 9dJYiB, etc. Use actual returned ids.

1. 5. Avoid blind UI automation first

Inspect runtime objects and methods before pixel-clicking.

When to use this skill

Use this skill when the user says things like:

• - “把这个表做成分页”
• “按类别分开 sheet”
• “给这张飞书表加几个页签”
• “我就想分页，你想办法解决”

Output expectation

When done, report:

• - which tabs were created/renamed
• which tab ids were found
• whether data filling was also completed
• whether browser login / relay was required
