+- ✅ Document dependencies and their roles based on package manifests
+- ✅ Describe modules, directories, and their purposes based on file contents
+- ❌ Don't assume any specific framework, architecture, or pattern
+- ❌ Don't invent project conventions not evidenced in code
+
+### Source Code Documentation
+- ✅ Only document modules, classes, and functions found in actual source files
+- ✅ Verify entry points from package.json scripts, main/bin fields, or config files
+- ✅ Document actual file organization and naming patterns
+- ❌ Don't assume MVC, microservices, or any specific architecture
+
+### Configuration Documentation
+- ✅ Document configuration files found in the project root and subdirectories
+- ✅ Verify build commands from package.json scripts or Makefile targets
+- ✅ Document environment variable usage from actual .env files or code references

+Generate comprehensive **${file.filename}** documentation.
+
+**Purpose:** ${file.description}
+
+**Critical Requirements:**
+1. **100% ACCURACY** - Only document what you can verify from context above
+2. **DOMAIN-SPECIFIC** - Use ${industry} terminology throughout
+3. **FILE-BASED EVIDENCE** - Reference specific files from the file tree above
+4. **STRUCTURED** - Use clear hierarchical sections with headers (##, ###, ####)
+5. **FILE-SPECIFIC FOCUS** - Focus on: ${file.description}
+6. **NO FRAMEWORK ASSUMPTIONS** - Document what exists, don't assume patterns
+7. **NO FUTURE CONTENT** - Do NOT add "Future Considerations", "Roadmap", or "Planned Features"
+
+**DO's:**
+- ✅ Reference specific files by path
+- ✅ Include actual version numbers from dependencies
+- ✅ Quote real commit messages
+- ✅ Use ${industry} domain terminology
+- ✅ Document ONLY current state of codebase
+
+**DON'Ts:**
+- ❌ Invent file paths that don't exist
+- ❌ Assume any specific framework or architecture
+- ❌ Make assumptions about unverified features
+- ❌ Use generic placeholders or invented code
+- ❌ Include speculative or future content
+
+**FORMAT:** Return ONLY the markdown content. No JSON wrapper, no outer code blocks. Start directly with:
+
+# ${file.filename.replace('.md', '')}
+
+Generate the documentation now.`;
