Copilot Skill & Instruction Viewer

See everything GitHub Copilot has loaded — Skills, Instructions, Prompts, Agents, and Hooks — in one visual board.

Ever wonder which .instructions.md or SKILL.md files Copilot is actually reading? This extension gives you a full swimlane visualization of every customization file on your machine, from both your current workspace and your personal user profile.

✨ Features

🗂️ Swimlane Board Visualization

All customization files displayed in a kanban-style board, grouped by type column — see everything at a glance without digging through folders.

🔍 Live Search with Highlight

Type to search across names, descriptions, and file paths. Matching cards glow and highlight the matched text. Non-matching cards dim — nothing disappears, so you always have full context.

🎛️ Type Filter Pills

Click any type pill (Skills, Prompts, Instructions…) to focus on that category. Click again to deactivate. Mix multiple filters freely.

📂 Workspace + User Profile

Scans both your open workspace folders and your personal Copilot configuration — all in one view.

⚡ Auto-Refresh

File system watcher detects when you add, edit, or delete customization files and refreshes the board automatically.

🖱️ One-Click to Open

Click any card to open the source file directly in the editor.

🪙 Token Estimation

Every card shows an estimated token count (~N tk) based on the file size using BPE approximation (~4 chars per token). The header also displays the total estimated tokens across all loaded files — helping you understand context window usage at a glance.

🔁 Load Behavior Indicator

Each card shows a color-coded chip that tells you when that file actually consumes tokens:

Hover the chip to see a full explanation.
