claude-code - 💡(How to fix) Fix [BUG] `/clear` bleeds into the next session (what also breaks cache) [2 comments, 2 participants]

Error Messages/Logs

TL;DR

The /clear command is not properly clearing the session, leaving behind artifacts in messages and causing cache misses.

Guidance

• The issue seems to be related to the /clear command not properly removing all messages from the session, specifically the <local-command-caveat> artifacts.
• To verify, try checking the anthropicReq.messages array after calling /clear to see if the artifacts are still present.
• One possible workaround could be to manually remove the <local-command-caveat> artifacts from the messages array after calling /clear.
• Investigate the code that handles the /clear command to see if there's a logic error or a missing step that's causing the artifacts to remain.

Example

No code snippet is provided as it's not clearly supported by the issue, but the anthropicReq.messages array could be checked and modified as follows:

// Example of what the messages array might look like
[
  {
    "role": "user",
    "content": [
      {
        "type": "text",
        "text": "<local-command-caveat>...</local-command-caveat>\n"
      },
      // ...
    ]
  }
]

// Potential workaround: remove the <local-command-caveat> artifact
const messages = anthropicReq.messages;
messages.forEach(message => {
  message.content = message.content.filter(part => !part.text.includes('<local-command-caveat>'));
});

Note that this is just a hypothetical example and may not be the actual solution.

Notes

The issue is related to a previous issue (https://github.com/anthropics/claude-code/issues/47098), but it's not clear if the fix for that issue will also fix this one. The Claude Code Version is 2.1.105, but it's not clear if upgrading to a newer version would fix the issue.

Recommendation

Apply workaround: manually remove the <local-command-caveat> artifacts from the messages array after calling /clear, as shown in the example above. This should help mitigate the issue until a more permanent fix can be found.
