Preferences (EXTEND.md)

Use Bash to check EXTEND.md existence (priority order):

# Check project-level first
test -f .baoyu-skills/baoyu-compress-image/EXTEND.md && echo "project"

# Then user-level (cross-platform: $HOME works on macOS/Linux/WSL)
test -f "$HOME/.baoyu-skills/baoyu-compress-image/EXTEND.md" && echo "user"

OpenClaw Migration Notes

• Migration mode: OpenClaw native first
• Preserved directories:
  • scripts: yes
  • references: no
  • prompts: no
• External dependencies: bun
• Risk level: low
• Environment variables (detected): HOME
• Config compatibility: keep original .baoyu-skills/<skill>/EXTEND.md behavior and add OpenClaw-compatible path in runtime wrappers when needed.

OpenClaw Preflight Checks

• Confirm bun is available when script examples use npx -y bun ....

Detected env vars: HOME

OpenClaw Failure Fallback

• If runtime dependency is missing, stop execution and return exact install/setup command.
