Added

• Compaction hook improvements: The before_compact session event now includes:

  • previousSummary: Summary from the last compaction (if any), so hooks can preserve accumulated context
  • messagesToKeep: Messages that will be kept after the summary (recent turns), in addition to messagesToSummarize
  • resolveApiKey: Function to resolve API keys for any model (checks settings, OAuth, env vars)
  • Removed apiKey string in favor of resolveApiKey for more flexibility

• SessionManager API cleanup:

  • Renamed loadSessionFromEntries() to buildSessionContext() (builds LLM context from entries, handling compaction)
  • Renamed loadEntries() to getEntries() (returns defensive copy of all session entries)
  • Added buildSessionContext() method to SessionManager
