Agent Flight Recorder

A local dashboard for your AI coding sessions. It reads the session files your editor has already written to its own storage and shows you what actually happened: how many turns, which models, how many tokens, and what it cost.

Everything runs on your machine. The extension makes no network requests.

What it shows

• Sessions — credits, tokens, turns and tool calls across every session
• Activity — wait time, time to first token, files changed, shell commands
• Models — which models ran, their billing source and token limits
• Session detail — token meters, context usage and the full transcript
• Health — whether logging is on, and which sessions were recorded

Getting started

Run Copilot Flight Recorder: Open Dashboard from the Command Palette (Ctrl+Shift+P).

There is no sign-in and nothing to configure. The dashboard finds your existing session files on its own. Some panels stay empty until your editor has written the optional agent debug log; the Health page tells you how to enable it.

Privacy

• Reads only files already on your disk, under your editor's own storage directories.
• Never writes to, modifies or deletes those files.
• Sends nothing anywhere. There is no telemetry and no network access of any kind — the panel's content security policy admits no remote origin, and all fonts and assets ship inside the extension.

Settings

copilotFlightRecorder.otelFile — absolute path to an OpenTelemetry JSONL export to read instead of the discovered one. Leave empty for automatic discovery.

Notes

Session file formats are not a documented, supported interface, so a future editor or assistant update can change them. When that happens a panel may show less until the reader is updated.
