Resilient PowerPoint Generation Workflow

Use shell_agent to create a PowerPoint presentation with:
- Specify exact number of slides needed
- Define content/topic for each slide
- Request file saved with clear filename (e.g., presentation.pptx)
- Ask agent to confirm the full file path after creation
- Request agent report any errors with full output

Create a PowerPoint presentation with 10 slides covering [topic]. Each slide should have a title and bullet points. Save it as presentation.pptx in the current working directory and report the full file path. If you encounter any errors, show the complete error message.

# save as: generate_presentation.py
from pptx import Presentation
from pptx.util import Inches, Pt
import os

# CRITICAL: Explicitly set and verify working directory
working_dir = os.getcwd()
print(f"Working directory: {working_dir}")

# Create presentation
prs = Presentation()

# Example: Add slides with content
slides_content = [
    {"title": "Slide 1 Title", "content": ["Bullet 1", "Bullet 2"]},
    {"title": "Slide 2 Title", "content": ["Point A", "Point B", "Point C"]},
    # Add more slides as needed
]

for slide_data in slides_content:
    slide_layout = prs.slide_layouts[1]  # Title and Content layout
    slide = prs.slides.add_slide(slide_layout)
    
    # Set title
    title = slide.shapes.title
    title.text = slide_data["title"]
    
    # Set content
    content = slide.placeholders[1]
    tf = content.text_frame
    tf.clear()  # Clear existing content
    
    for i, point in enumerate(slide_data["content"]):
        if i == 0:
            p = tf.paragraphs[0]
        else:
            p = tf.add_paragraph()
        p.text = point
        p.font.size = Pt(18)

# Save to current working directory with explicit path
output_filename = "presentation.pptx"
output_path = os.path.join(working_dir, output_filename)
prs.save(output_path)

print(f"Presentation saved to: {output_path}")
print(f"File exists: {os.path.exists(output_path)}")
print(f"File size: {os.path.getsize(output_path)} bytes")

# Execute the script with full error output
python generate_presentation.py 2>&1

# Or if using run_shell tool, ensure 2>&1 is included

# Check if python-pptx is installed
python -c "import pptx; print(pptx.__version__)" 2>&1

# Check working directory
pwd
ls -la

# Check Python version
python --version

# Run with verbose error output
python -u generate_presentation.py 2>&1 | tee execution_log.txt

# Find all .pptx files in workspace
find . -name "*.pptx" -type f 2>&1

# Or search for specific filename
find . -name "presentation.pptx" -type f 2>&1

# If not found locally, search broader (last resort)
find /workspace -name "*.pptx" -type f 2>/dev/null

# Get the full path from find output
FILE_PATH=$(find . -name "presentation.pptx" -type f | head -1)

# Copy to current directory
cp "$FILE_PATH" . 2>&1

# Or move it
mv "$FILE_PATH" . 2>&1

# List file with details
ls -la presentation.pptx

# Check file size (should NOT be 0 bytes)
file presentation.pptx
stat presentation.pptx | grep Size

# Verify it's a valid PowerPoint file
python -c "from pptx import Presentation; prs = Presentation('presentation.pptx'); print(f'Slides: {len(prs.slides)}')" 2>&1

# Attempt 1: shell_agent (via task delegation)

# If shell_agent failed, proceed to Path 2:

# Step 1: Write Python script

# Step 2: Execute with error capture
python generate_presentation.py 2>&1
# Output: Working directory: /workspace/task_123
#         Saved: presentation.pptx

# Step 3: Locate (in case it's nested)
find . -name "presentation.pptx" -type f

# Step 4: Verify
ls -la presentation.pptx
