feat(hooks): use auto flag for session resumption after compaction

code-yeongyu · code-yeongyu · commit bd22f1cefe7e · 2026-01-08T23:05:12.000+09:00
- executor.ts: Added `auto: true` to summarize body, removed subsequent prompt_async call - preemptive-compaction/index.ts: Added `auto: true` to summarize body, removed subsequent promptAsync call - executor.test.ts: Updated test expectation to include `auto: true` Instead of sending 'Continue' prompt after compaction, use SessionCompaction's `auto: true` feature which auto-resumes the session. 🤖 GENERATED WITH ASSISTANCE OF [OhMyOpenCode](https://github.com/code-yeongyu/oh-my-opencode)
