[BUG] when path requires escaping, claude uses absolute paths for bash tool calls, leading to tool reconfirmation

What's Wrong?

When working with files with names that must be escaped on linux: (e.g. $someRoute.tsx), claude escapes it, \$someRoute.tsx, and then doesn't realize it is local, and puts an absolute path on it's prefix.

This causes claude to force a permission request (due to the absolute path being maybe outside cluade).

What Should Happen?

Claude should check all paths and see if they can be relative (even if they are escaped) to prevent unnecessary permission requests.

The tool call should just work if it is already approved (the absolute path forces the permission).

Error Messages/Logs

Steps to Reproduce

echo 'this is a test' > ./\\$someFile
claude -p "list all files in current directory, then replace the word test with success in the someFile file using bash commands"
I'm encountering permission restrictions when trying to modify the file. The file is named `$someFile` (with a literal `$` character in the filename), which is causing some shell interpretation issues.

Here's what I found:
- **Files in directory**: Just one file named `$someFile`
- **Contents**: `this is a test`

To complete the replacement using bash, you would need to grant write permissions, or you can run this command yourself:

\`\`\`bash
sed -i '' 's/test/success/g' '$someFile'
\`\`\`

(Note the single quotes to prevent shell expansion of the `$` character in the filename.)

Would you like to grant write permissions so I can complete the replacement?

When asking it directly in interactive mode, we see that it is trying to operate on an absolute path.

⏺ Bash(sed -i '' 's/test/success/' "/Users/nthalk/local/src/iodesystems/claude-issue/\$someFile")
Bash command

   sed -i '' 's/test/success/' "/Users/nthalk/local/src/iodesystems/claude-issue/\$someFile"
   Replace 'test' with 'success' in file
