  # [Document Title]
  
  ## Executive Summary
  [Brief overview of key content - use domain knowledge]
  
  ## Background
  [Context and scope - leverage embedded expertise]
  
  ## Main Content
  [Organized sections with headers, lists, tables]
  
  ## Limitations & Notes
  [Transparent about data source limitations if relevant]
  
  ## Recommendations/Next Steps
  [Actionable guidance based on available information]

# Generate Project Status Report

## Step 1: Detect failures (if applicable)
Tool check: read_webpage failed 3x, search_web failed 2x → PIVOT to fallback workflow

## Step 2: Write Markdown source
write_file
path: /tmp/project_status.md
content: |
  # Project Status Report
  
  ## Executive Summary
  This report summarizes project progress using established methodologies.
  
  ## Current Status
  - Phase 1: Complete
  - Phase 2: In Progress (75%)
  - Phase 3: Not Started
  
  ## Risks & Mitigation
  Standard risk framework applied...
  
  ## Recommendations
  1. Continue current trajectory
  2. Schedule stakeholder review

> **Note**: Specific metrics from project management tool were unavailable; guidance reflects standard practices.

## Step 3: Sanitize for PDF
write_file
path: /tmp/project_status_sanitized.md
content: |
  [Same content with any special chars replaced per table above]

## Step 4: Convert (try each, proceed on failure)
run_shell
command: pandoc /tmp/project_status.md -o project_status.docx

run_shell
command: pandoc /tmp/project_status_sanitized.md -o project_status.pdf

run_shell
command: pandoc /tmp/project_status.md -o project_status.html

## Step 5: Verify
run_shell
command: ls -lh project_status.*

pandoc PDF fails?
  ├─→ Try --pdf-engine=xelatex
  │   └─→ Fails?
  │       ├─→ Try --pdf-engine=wkhtmltopdf
  │       │   └─→ Fails?
  │       │       └─→ Use Python fpdf2 (most reliable)
  │       └─→ Success → Done
