Review feature design and append findings

Review feature design against CLAUDE.md standards and append findings

Getting a second review of a feature design before implementation to catch architectural or scope issues

• · Feature spec directory path (e.g., docs/specs/auth-flow)
• · design.md file from that directory
• · Existing review-design.md with prior rounds

• · Findings appended to review-design.md (Issues, Suggestions, Confirmations sections)
• · DESIGN APPROVED marker if no blocking issues remain

• · Read (CLAUDE.md, design.md, review-design.md)
• · Write (append only to review-design.md)

• · CLAUDE.md exists in project root
• · design.md exists in $ARGUMENTS directory
• · review-design.md can be created if missing

• · $ARGUMENTS path does not exist
• · design.md not found in specified directory
• · Attempted to modify existing review-design.md content (append-only requirement)

• · Append-only to review-design.md (prevents losing discussion history)
• · Checks CLAUDE.md standards explicitly (not style preferences)
• · Tracks round numbers to prevent re-raising resolved issues
• · Distinguishes blocking (must fix) from non-blocking (suggestion)
• · Escalates to human if round 3+ with issues remain
