Lark Report Collector

Collect weekly report data from Lark Reports, summarize into Lark Docs, and send notifications.

When to Use

• - "Collect this week's/last week's reports for Photo/Bloom/H&F"
• "Who hasn't submitted their weekly report?"
• "Summarize weekly reports into a Lark doc"

Hard Rules (battle-tested)

1. 1. Reports is a SPA — curl/webfetch returns nothing. Must use browser (profile=openclaw)
2. Pagination is reversed — Next = older weeks, Previous = newer weeks
3. Always snapshot to confirm week title after pagination (most common error: collecting wrong week)
4. One page may show multiple weeks — data is sorted by time, a single page can span 2-3 weeks
5. blocktype mapping — 12=bullet, 13=ordered (NOT 9/10! Those are heading7/heading8)
6. Never restart gateway inside a sub-agent (kills itself)
7. Sub-agents need exact URLs and steps — don't let them explore on their own

Complete Workflow

Step 1: Navigate to Reports

CODEBLOCK0

Prerequisites: openclaw browser must have active Lark login session.

Step 2: Select Report Template

Snapshot and click the target template menuitem in the left sidebar "Received by me".

Step 3: Navigate to Target Week

Page defaults to latest data. Week title format: INLINECODE1

Pagination (critical):

• - Next button = older weeks ⬅️
• Previous button = newer weeks ➡️
• Page display: "2/25" (page 2 of 25), page 1 is newest

⚠️ Snapshot and confirm the date in the title after every page turn!

Step 4: Extract Submitted Members Data

• - Same page may show multiple weeks — only extract rows belonging to target week
• Paginate through all rows for the target week
• Append to local file after each extraction (prevents data loss)

Step 5: Get Unsubmitted List

"Not submitted: N" button has no snapshot ref. Click via JS evaluate:

CODEBLOCK1

Dialog shows: unsubmitted count + names + departments.

Step 6: Create Lark Doc

Create document via Lark Open API (see lark-api skill for auth).

block_type reference (verified):

block_type	Type	JSON field
2	Text	INLINECODE3
3

Heading 1 | "heading1" |
| 4 | Heading 2 | "heading2" |
| 5 | Heading 3 | "heading3" |
| 12 | Bullet list ✅ | "bullet" |
| 13 | Ordered list ✅ | "ordered" |
| 22 | Divider | "divider" |

❌ 9=heading7, 10=heading8. NOT lists!

Step 7: Send Notification

Send message via Lark API with doc link.

⚠️ Wrong week | Collected Feb 10-14 instead of Feb 3-7 | Always confirm week title after pagination | | 3 | ❌ 200K tokens burned | Tried curl on SPA | Reports is SPA, browser only | | 4 | ❌ 200K tokens burned | Sub-agent explored on its own | Give exact URLs and steps | | 5 | ✅ Success | Precise instructions + correct block_types | Template is key |

Known Limitations

• - Lark Report Open API unavailable on international version (returns 404) — browser only
• Browser login session may expire — re-login needed
• Export button (Excel) untested — potential alternative
