OpenClaw v2026.3.7 Released: Sub-agent Depth Extended to 5 Levels

Release Date: March 7, 2026

This update brings a Feishu Wiki bidirectional sync skill, major sub-agent concurrency scheduling optimizations (supporting up to 5 nested levels), Canvas A2UI push support, and a brand-new side-peace secure secret handoff solution.

Core Updates

Feishu Wiki Bidirectional Sync Skill

Added a new Feishu knowledge base bidirectional sync skill with support for bulk Wiki node export. You can now sync Feishu wiki content to your local workspace, or push local content back to Feishu Wiki.

Key features:

  • Bulk export Wiki nodes as Markdown files
  • Preserves multi-level directory structure
  • Incremental sync — only updates changed content
  • Supports attachment and image downloads

Sub-agent Concurrency Scheduling Optimization

Sub-agent nesting depth expanded from 2 to 5 levels, enabling more complex task decomposition and parallel execution.

  • Maximum nesting depth: 5 levels
  • Concurrent sub-agents: up to 10 parallel sub-agents per parent agent
  • New sub-agent status monitoring commands
  • Improved context passing between sub-agents

Canvas A2UI Push

The Canvas panel now supports A2UI push with real-time screenshot feedback. Agents can proactively push UI to Canvas and receive screenshots to confirm results.

side-peace Secure Secret Handoff

New side-peace skill provides a zero-dependency secure secret handoff solution. Users submit secrets via a browser form; the agent receives them through a temporary file — secrets never pass through any logs or message channels.

How to Upgrade

npm update -g openclaw@latest
# or
pnpm update -g openclaw@latest

Run the diagnostic command after upgrading to verify your environment:

openclaw doctor

Important Note

Extended sub-agent depth may increase API token consumption. We recommend configuring reasonable timeout and depth limits in your config file.
