[BUG] Claude commands fail with EACCES permission denied error when creating files

Preflight Checklist

• I have searched existing issues and this hasn't been reported yet
• 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?

When I run a Claude command like claude "create a new Python file" or claude "add type hints to test.py", Claude shows an error "EACCES: permission denied" and the file isn't created.

The command fails immediately after accepting the file write permission prompt. The error occurs consistently across multiple commands that involve file creation or modification.

What Should Happen?

Claude should execute the command successfully and create or modify the Python file without any permission errors. The file write operation should complete after the user accepts the permission prompt.

Error Messages/Logs

Error: EACCES: permission denied, open '/path/to/project/test.py'
    at Object.openSync (node:fs:601:3)
    at Object.writeFileSync (node:fs:2249:35)
    at ClaudeCode.writeFile (/usr/local/lib/node_modules/@anthropic-ai/claude-code/dist/index.js:123:10)
    at async ClaudeCode.executeCommand (/usr/local/lib/node_modules/@anthropic-ai/claude-code/dist/index.js:456:5)

Steps to Reproduce

1. Create a new project directory: mkdir my-project && cd my-project
2. Run a Claude command: claude "create a Python file called hello.py that prints Hello World"
3. When prompted for file write access, accept/allow the permission
4. Observe the error: "EACCES: permission denied"
5. The file hello.py is not created in the directory

Note: This also happens with commands that modify existing files, e.g., claude "add type hints to existing_file.py"

I've seen this personally. It looks like the issue may be related to absolute vs relative paths.

⏺ Write(/<home>/<path_to_project>/dep_graph_plan.md)
  ⎿  Error: EACCES: permission denied, mkdir '<home>'

∴ Thinking…

  The Write tool is having path issues again. Let me check the current directory and use the correct path.

⏺ Bash(pwd)
  ⎿  <home>/<path_to_project>

∴ Thinking…

  The Write tool seems to have issues with absolute paths. Let me try using a relative path.

⏺ Write(dep_graph_plan.md)
  ⎿  Wrote 310 lines to dep_graph_plan.md

Edit: claude --version 2.1.117

this is a recurring issue. Claude code goes back to the overall tasks view.
