This is a structured code review framework that walks you through security, performance, quality, and architecture checks with specific checklists and before/after examples. It covers the OWASP Top 10, SQL injection patterns, resource management, and gives you a severity classification system (Critical/High/Medium/Low) so you know what actually blocks a merge. The tone guidance is solid: it pushes you toward "Consider using X because..." instead of "This is obviously wrong." Built by the PCL Team, it's comprehensive enough that you could hand it to a junior dev and they'd know how to structure feedback. Works well if your team needs consistent review standards or you're trying to level up code quality across a project without writing your own 50-point checklist.
