## Summary - emit ACP `usage_update` notifications from top-level Claude `stream_event` message usage - keep tracking a usage snapshot across `message_start` and `message_delta` so partial deltas still produce a complete total - preserve the existing `result`-path update as the final exact/cost-bearing usage event ## Why Claude SDK stream events already carry incremental usage on `message_delta`, but `claude-agent-acp` currently ignores that path and only emits `usage_update` from the final `result`. This makes usage appear stale until the turn ends in ACP clients that expect live context usage updates. ## Verification - built the repo with `npm run build` - ran a direct ACP stdio client against the patched local build - observed `usage_update` notifications emitted before the final result-path usage update Patched local smoke-test output included this sequence: - `usage_update used=20973 size=200000` - `agent_message_chunk text=TEST_OK` - `usage_update used=20989 size=200000` - `usage_update used=20989 size=1000000 cost=0.1314875` --------- Co-authored-by: Ben Brandt <benjamin.j.brandt@gmail.com>
