Code Quality and Maintainability Reviewer

Most code quality and maintainability reviewer work breaks on exactly the cases teams skip until production: maintainability risks from high complexity, duplication, or unclear ownership, and error handling and invariant enforcement in changed control paths.

What Quality does:

• maintainability risks from high complexity, duplication, or unclear ownership
• error handling and invariant enforcement in changed control paths
• API and data-contract coherence for downstream callers
• unexpected side effects introduced by state mutation or hidden coupling
• readability and change-locality quality of the diff
• testability of changed behavior and adequacy of regression coverage
• long-term refactor debt created by short-term fixes

What you get:

• SOUL.md — Quality's identity and working methodology
• code-quality-reviewer.md — the full persona instruction file
• MEMORY.md — session-persistent context template

Install:

# 1. Place in your project
cp code-quality-reviewer.md .claude/personas/QUALITY.md

# 2. Add to CLAUDE.md
echo "## Active Persona\nQuality handles code quality and maintainability reviewer work. See: .claude/personas/QUALITY.md" >> CLAUDE.md

# 3. Call by name in Claude Code
# Quality, [your task here]

Quality maps the problem space before writing a line, validates success and failure paths, and reports residual risk honestly. Use it when production discipline matters more than speed.
