Persist usage statistics (currently only shown once when CLI exits) #1394
Description
Describe the feature or problem you'd like to solve
Copilot CLI does not persist usage statistics (premium requests, token usage per model)
Proposed solution
Copilot CLI does not provide usage statistics for individual users on an Enterprise plan.
Therefore, I asked Copilot CLI to generate a Python script to analyze its own data in ~/.copilot/ directory (see screenshot in context).
Unfortunately the following valuable information is currently only shown once to the user but not persisted in events.jsonl or other files:
Total usage est: 7 Premium requests
API time spent: 2m 59.626s
Total session time: 12m 15.77s
Total code changes: +206 -77
Breakdown by AI model:
claude-sonnet-4.5 453.0k in, 13.1k out, 405.7k cached (Est. 7 Premium requests)
When user exits Copilot CLI, please write information above into ~/.copilot/session-state/events.jsonl (e.g. as part of message with type abort) or another file. Please ensure that statistics cover the entire session (including continuations).
