P2 Bug Report: Third Example Not Filling Chat Box

Status

• Date: 2025-11-29
• Priority: P2 (UX issue)
• Component: src/app.py - Gradio examples
• Resolution: FIXED in commit 2ea01fd

---

Symptoms

When clicking the third example in the Gradio UI:

• Example 1 (female libido): ✅ Fills chat box correctly
• Example 2 (ED alternatives): ✅ Fills chat box correctly
• Example 3 (HSDD testosterone): ❌ Does NOT fill chat box

User Experience

User clicks example → nothing happens → confusion

---

Root Cause Hypothesis

The third example contains parentheses and an abbreviation:

"Testosterone therapy for HSDD (Hypoactive Sexual Desire Disorder)?"

Possible causes:

1. Parentheses - Gradio may have parsing issues with (...) in example text
2. Text length - When expanded, this is the longest example
3. Special characters - The combination of abbreviation + parenthetical may confuse Gradio's example caching

---

The Fix

Simplify the example text - expand the abbreviation and remove parentheses:

# Before (broken)
"Testosterone therapy for HSDD (Hypoactive Sexual Desire Disorder)?"

# After (fixed)
"Testosterone therapy for Hypoactive Sexual Desire Disorder?"

This:

1. Removes problematic parentheses
2. Makes the text more readable (no cut-off abbreviation)
3. Users don't need to know what HSDD stands for

Test Plan

• Change example text in src/app.py
• Deploy to HuggingFace Space
• Verify all 3 examples fill chat box correctly
• make check passes
