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. 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

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:

(() => {
  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.

| # | 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
