copilot-usage-stats

Report how many tokens, API calls, and how much wall time a project has consumed in Copilot, and convert those tokens into GitHub AI Credits and dollars at the published per-model rates. Carries the repository-scoped join, the verified fact that input_tokens already contains cache_read_tokens, and the cost column that holds a legacy request multiplier rather than money. USE FOR: how many tokens has this project used, what did this repo cost me in credits or dollars, token consumption per repository or branch, usage for a day or a date range, which model burned the most context, cache-hit ratio, API call counts, per-session totals, comparing VS Code chat against Copilot CLI usage. DO NOT USE FOR: advice on lowering spend or token-reduction tips (use chronicle cost-tips), standups and session search (use chronicle), measuring whether a Customization triggers or works (use agent-evals), choosing a Copilot plan, invoices, or seat management.

Compatibility

Requires the `copilot_sessionStoreSql` tool with `github.copilot.chat.localIndex.enabled` enabled, plus cloud sync (`chat.sessionSync.enabled`). The local SQLite store records no token data, so a local-only setup cannot answer any question in this Skill.
