TypeScript Claude Code Software Engineering Code Review

Overview

A Claude Code skill that implements Fagan’s formal software inspection methodology — a structured, systematic approach to code review that was pioneered at IBM and proven to catch defects early.

How It Works

Run /fagan-inspect on a file or PR to get a structured review following the formal inspection process:

  1. Planning: Identifies scope and review criteria
  2. Overview: Summarizes the code’s purpose and architecture
  3. Preparation: Individual review with defect logging
  4. Inspection: Systematic walkthrough with categorized findings
  5. Rework: Prioritized action items by severity
  6. Follow-up: Verification checklist

Each defect is classified by type (logic, interface, data, control flow) and severity (critical, major, minor, cosmetic).

Outcomes

  • Formal inspection methodology
  • Structured defect classification
  • Automated review checklist generation
