  • This is a single bug report (please file separate reports for different bugs)
  • I am using the latest version of Claude Code

What's Wrong?

User prompts should be read as the user types them. If the users text needs to be pre-processed to escape characters that should be done by the input handler. When I type a path or some other sequence of text with backslashes, For example: ~.claude, it shouldn't turn into ~.claude. If the internal mechanism needs a \ escaped, it should escape it. The user shouldn't have to type ~\.claude ever to represent a single .

What Should Happen?

A user should type ~.claude and see ~.claude when it posts, not ~.claude. If the input handler escapes it for internal use, it should un-escape it for re-displaying it.

Error Messages/Logs

Steps to Reproduce

Type text in a prompt for Claude... use \ within that text. It's context sensative so if the \ is followed by a . you just get a . instead of . as you should.

extent analysis

TL;DR

The issue can be fixed by modifying the input handler to properly escape and unescape backslashes in user prompts.

Guidance

  • The input handler should be updated to escape backslashes only when necessary for internal processing, and then unescape them when displaying the user's input.
  • Verify that the input handler is correctly handling backslashes by testing with different input sequences, such as ~\.claude and ~\\\.claude.
  • Check the documentation for the Anthropic API to see if there are any specific requirements or guidelines for handling backslashes in user input.
  • Consider adding a feature to display the escaped input internally, to help with debugging and testing.

Example

No code example is provided as the issue does not include specific code details.

Notes

The fix may require changes to the input handler's logic for escaping and unescaping backslashes, and may involve additional testing to ensure that the fix works correctly in all scenarios.

Recommendation

Apply workaround: The issue is likely due to a change in the input handler's behavior, and a workaround can be applied by modifying the input handler to correctly handle backslashes.
