Why it is useful: For job-search and networking agents that need LinkedIn reads from the user's own session. Caveat from the README: LinkedIn's User Agreement prohibits automated access and accounts can be restricted, so deny the write tools (send_message, connect_with_person, reply_to_conversation, archive_conversation, dismiss_job) and keep volume low. ## live-panel - Page: https://agent-skill-hub.pages.dev/e/live-panel/ - Source: https://github.com/ythx-101/live-panel-skill - Kind: Skill - Author: ythx-101 - License: MIT - Works with: claude-code, codex - Tags: video, rendering, agent-skills - Added: 2026-11-04; last verified 2026-11-04 via git ls-remote - Install: `git clone https://github.com/ythx-101/live-panel-skill ~/.claude/skills/live-panel` Agent skill and stdlib Python renderer that turns one JSON config into an always-running terminal-style or pastel architecture diagram, with flowing packets, a scrolling log and counters, rendered to an H.264 mp4 or a self-contained looping web page. Why it is useful: For agents that make animated architecture or agent-tree diagrams for posts and videos; the agent writes the JSON, renders, then runs check_frames.py to catch text overflow. Needs Chrome or Chromium and ffmpeg; Linux and macOS only (Windows through WSL). Example designs credit their original authors. ## magpie - Page: https://agent-skill-hub.pages.dev/e/magpie/ - Source: https://github.com/yetone/magpie - Kind: Model gateway - Author: yetone - License: MIT - Works with: claude-code, codex, gemini-cli, opencode - Tags: gateway, routing, macos, multi-provider - Added: 2026-11-04; last verified 2026-11-04 via git ls-remote Menu-bar app and local gateway that serves every coding agent's model from one place and moves to the next account when a quota runs out.
