Bug: Claude defaults to ~ tilde shorthand instead of full absolute paths when referencing files

Bug Report

Summary: When Claude references a file location in a response, it consistently uses ~ tilde shorthand (e.g. ~/clawd/outputs/file.md) rather than the full absolute path (e.g. /home/ubuntu/clawd/outputs/file.md). This is a usability bug in agentic/CLI contexts where users expect copy-pasteable absolute paths.

Steps to reproduce:

1. Ask Claude to copy or create a file and tell you where it is
2. Observe response uses ~/... instead of /home/<user>/...

Expected behavior: All file path references in responses should be full absolute paths that can be used directly in any shell context without expansion.

Actual behavior: Claude defaults to ~/... shorthand, which:

• May not resolve correctly depending on shell/user context
• Requires users to mentally expand or re-ask for the full path
• Persists as a bad pattern across sessions despite user correction

Suggested fix:

• Training preference: absolute paths over tilde shorthand in file references
• Or: system-level instruction in Claude Code CLI that enforces this

Environment: Claude Code CLI, agentic workflows, Linux (Ubuntu)
