[BUG] # shortcut does not write to CLAUDE.md

What's Wrong?

Environment:

• OS: macOS 14 (Darwin 24.6.0)
• Claude Code version: (run claude --version to get this)

Description:
The # shortcut (typing # text as a message) is supposed to append text directly to
~/.claude/CLAUDE.md. Instead, the message is sent to Claude normally but nothing is
written to CLAUDE.md.

Steps to reproduce:

1. Open Claude Code
2. Type # some text to remember and send
3. Check ~/.claude/CLAUDE.md

Expected behavior:
some text to remember is appended to ~/.claude/CLAUDE.md

Actual behavior:
CLAUDE.md is unchanged. The message is received by Claude as a regular chat message.

Workaround:
Manually editing via /memory (opens file in nano) works correctly.

What Should Happen?

some text to remember is appended to ~/.claude/CLAUDE.md

Steps to Reproduce

⏺ Here are the steps to fill in:

---

1. Open Claude Code in any directory
2. Type # some text to remember as a message and press Enter
3. After Claude responds, run /memory — it opens ~/.claude/CLAUDE.md in nano
4. Observe that the text from step 2 was not appended to the file
5. Exit nano (Ctrl+X)

Additional context:

• The message IS received by Claude as a normal chat message
• Manually editing via /memory works correctly
• File permissions on ~/.claude/CLAUDE.md are correct (-rw-r--r--, owned by user)
• No error or confirmation message is shown when using #, making the failure silent
