Lark Report Collector

Collect weekly reports from Lark Reports (oa.larksuite.com), summarize into Lark Docs, and notify. Use when: (1) collecting weekly reports from specific teams/templates, (2) checking who hasn't submitted reports, (3) generating report summaries as Lark documents. Requires browser automation (Reports is a SPA, API not available on international Lark).

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. Reports is a SPA — curl/web_fetch 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. block_type 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

text

browser action=navigate profile=openclaw targetUrl="https://oa.larksuite.com/report/record/entry"

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: "Feb 2 ~ Feb 8 Submitted: 18"

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:

javascript

(() => {
  const btns = [...document.querySelectorAll('button')].filter(
    b => /Not submitted.*\d/.test(b.innerText)
  );
  if(btns.length) { btns[0].click(); return 'clicked'; }
  return 'not found';
})()

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	"text"
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.

Lessons Learned (6 real attempts)

#	Result	Root Cause	Lesson
1	❌ Self-killed	Sub-agent ran gateway restart	Never restart gateway in sub-agent
2	⚠️ 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
