[BUG] Memory Tool Path Validation Error

Description

Claude Code is throwing a path validation error when attempting to use the memory tool, preventing successful execution of memory-related operations.

Error Message

Error: Must use correct memory file path: /path/to/project/CLAUDE.md
    at file:///[NODE_PATH]/.asdf/installs/nodejs/22.4.1/lib/node_modules/@anthropic-ai/claude-code/cli.js:2716:1043
    at process.processTicksAndRejections (node:internal/process/task_queues:95:5)
    at async D (file:///[NODE_PATH]/.asdf/installs/nodejs/22.4.1/lib/node_modules/@anthropic-ai/claude-code/cli.js:777:57562)

Environment

• Node.js Version: v22.4.1
• Platform: macOS/Linux (based on path structure)
• Claude Code Installation: Via npm global install
• Project Context: Python project with virtual environment

Steps to Reproduce

1. Navigate to a project directory
2. Activate virtual environment (if applicable)
3. Attempt to use Claude Code with memory functionality
4. Error occurs during memory tool execution

Expected Behavior

The memory tool should successfully validate and use the correct memory file path without throwing validation errors.

Actual Behavior

The application crashes with a path validation error, specifically complaining about the memory file path format or location.

Additional Context

• The error appears to be related to path validation logic in the memory tool implementation
• The error occurs at line 2716 in the CLI module
• This seems to be a regression or configuration issue with how memory file paths are resolved
• The project appears to be using a CLAUDE.md file for memory storage

Stack Trace Location

• File: cli.js
• Line: 2716:1043
• Function: Memory tool path validation

Suggested Investigation Areas

1. Memory file path resolution logic
2. Cross-platform path handling
3. Project directory detection
4. Memory tool initialization process

Workaround

None currently known - the error prevents continued use of Claude Code in projects requiring memory functionality.
