Summary

The session-memory hook currently captures the last 15 JSONL lines from a session. This can be insufficient for longer conversations, and the count should be configurable.

Proposed Changes

1. Add messages config option to hook entry:

{
  "hooks": {
    "internal": {
      "entries": {
        "session-memory": {
          "enabled": true,
          "messages": 100
        }
      }
    }
  }
}

2. Fix message filtering order: Currently the code does slice(-15) first, then filters for user/assistant messages. This means if those 15 lines contain tool calls, you get fewer actual messages.

   Proposed: Filter user/assistant messages first, then slice to guarantee N actual conversation messages.

3. Default: Keep 15 for backward compatibility.

Use Case

Power users with long sessions want to capture more context when running /new. I've been running a local override with messages: 100 and it works great.

Implementation Notes

• Config schema update for hook entry type
• Handler reads messages from config
• HOOK.md documentation update
• Will include tests
