Skill: Update Documentation

What This Skill Does

Updates existing project documentation to reflect code changes. Handles:

• Detecting which documentation is affected by recent changes
• Updating module documentation (symbols, structure, data flow)
• Updating feature documentation (new behavior, changed flows)
• Updating the project overview (new modules, changed architecture)
• Ensuring cross-references remain valid

When to Use

• After implementing a feature or fixing a bug that changes behavior
• After refactoring that affects module structure or symbols
• When the user says documentation is "outdated" or asks to "update docs"
• After a plan phase is completed and code has changed
