GitHub Copilot Lens

See everything Copilot does — in real time.

Ever wondered what's happening behind the scenes when GitHub Copilot CLI is working? Copilot Lens gives you a live dashboard showing every turn, tool call, agent chain, and token — right inside VS Code.

Why Copilot Lens?

🔍 Full Transparency — Watch Copilot think, plan, and execute in real time

🤖 Multi-Agent Visibility — See the full agent hierarchy: PM calls backend-developer, backend-developer calls tester — every chain visualized

🛠️ Tool Call Inspector — Click any tool badge to see exactly what command was run, what file was edited, what was searched

📊 Session Analytics — Turns, tokens, tools, agents, checkpoints, modified files — all at a glance

Highlights

Agent Call Trees — When Copilot spawns sub-agents, see the full parent→child tree with tool badges, results, and timing for each agent.

Tool Inspector — Click any tool badge to drill into the exact input and output. PowerShell commands, file edits, grep searches — nothing is hidden.
