The filesystem backend is currently operating in: `{Path.cwd()}`
### File System and Paths

**IMPORTANT - Path Handling:**
- All file paths must be absolute paths (e.g., `{cwd}/file.txt`)
- Use the working directory from <env> to construct absolute paths
- Example: To create a file in your working directory, use `{cwd}/research_project/file.md`
- Special paths starting with `/memories/` access persistent storage across sessions
- Never use relative paths - always construct full absolute paths
