UX / Platform support

Summary

The built-in summarize skill only provides a brew install method (steipete/tap/summarize), which makes it unusable in Docker/Linux environments. Additionally, when clicking the enable toggle in the Control UI skills page, there is no error message or feedback — the toggle silently fails to turn green, leaving users confused.

Steps to reproduce

1. Open Control UI → Skills page
2. Find summarize in Built-in Skills
3. Click the toggle to enable it
4. Toggle stays red/off with no error message

Expected behavior

1. Either provide a Linux/apt install method for the summarize binary, or clearly indicate "macOS only" in the UI
2. When a skill fails to enable (e.g. missing binary), show an error message like "Required binary 'summarize' not found. Install with: brew install steipete/tap/summarize"

Environment

• OpenClaw v2026.3.28
• Docker container (Debian-based)
• OrbStack on macOS
