/btw (aside) conversations are no longer persisted to disk as of Claude Code 2.1.104. The UI works — you can open a /btw side conversation, type messages, and get responses — but when the conversation closes, nothing is written to disk.

Description

/btw (aside) conversations are no longer persisted to disk as of Claude Code 2.1.104. The UI works — you can open a /btw side conversation, type messages, and get responses — but when the conversation closes, nothing is written to disk.

Expected behavior

In 2.1.97 and earlier, /btw created agent-aside_question-*.jsonl files in the session's subagents/ directory. These files contained the full conversation and could be referenced later.

Actual behavior

In 2.1.104, no aside_question files are created. The main session JSONL has isSidechain: false on every message. The /btw conversation simply vanishes when closed.

Steps to reproduce

  1. Start a Claude Code session (2.1.104)
  2. Open a /btw conversation and have a multi-message exchange
  3. Close the /btw conversation
  4. Check ~/.claude/projects/<project>/<session-id>/subagents/ — no aside_question files exist
  5. Check the main session JSONL — no isSidechain: true messages

Impact

Users who rely on /btw for capturing ideas mid-session lose all that content. This is especially impactful for users who have built tooling to mine /btw conversations (e.g., extracting ideas and feedback into external memory systems).

Environment

  • Claude Code 2.1.104
  • macOS Darwin 25.4.0
  • Last working version: 2.1.97

extent analysis

TL;DR

Downgrade to Claude Code 2.1.97 to restore persistence of /btw conversations to disk.

Guidance

  • Verify the issue by checking the subagents/ directory for the absence of agent-aside_question-*.jsonl files after closing a /btw conversation in Claude Code 2.1.104.
  • Compare the behavior with Claude Code 2.1.97 to confirm that the issue is version-specific.
  • Consider reaching out to the developers or checking the release notes for Claude Code 2.1.104 to see if this is a known issue with a planned fix.
  • If downgrading is not feasible, explore alternative methods for capturing ideas mid-session, such as using external note-taking tools.

Notes

The provided information suggests a regression in Claude Code 2.1.104, but without access to the codebase or more detailed documentation, it's difficult to provide a more specific fix.

Recommendation

Apply workaround: Downgrade to Claude Code 2.1.97, as it is the last known version where /btw conversations were persisted to disk correctly. This will allow users to capture ideas mid-session until a fix is available for the newer version.
