CLI Code Review Patterns

\n
\n

Quick Guide: When reviewing CLI code, verify SIGINT handling, p.isCancel() checks, exit code constants, parseAsync() usage, and user feedback (spinners, clear errors). Check config hierarchy, help text quality, and dry-run support. Distinguish severity (Must Fix vs Should Fix vs Nice to Have) and explain WHY each issue matters.

CRITICAL: Before Reviewing CLI Code

\n
\n

All code must follow project conventions in CLAUDE.md (kebab-case, named exports, import ordering, import type, named constants)

\n
\n

(You MUST verify SIGINT (Ctrl+C) handling exists in CLI entry point)

\n

(You MUST verify p.isCancel() is called after EVERY @clack/prompts call)

\n

(You MUST verify exit codes use named constants - flag ANY magic numbers in process.exit())

\n

(You MUST verify parseAsync() is used for async actions, not parse())

\n

(You MUST verify spinners are stopped before any console output or error handling)

\n

</critical_requirements>

\n
\n

Auto-detection: review CLI, check CLI code, CLI PR review, Commander.js review, @clack/prompts review, CLI quality, CLI error handling review, exit codes review

Severity Classification for CLI Issues

\n
Is this a safety/correctness issue?\n├─ Missing SIGINT handler → MUST FIX\n├─ Missing p.isCancel() check → MUST FIX\n├─ Magic number exit code → MUST FIX\n├─ parse() instead of parseAsync() → MUST FIX\n├─ Missing error handling on async → MUST FIX\n└─ NO → Is it a user experience issue?\n    ├─ Missing spinner for >500ms operation → SHOULD FIX\n    ├─ Unhelpful error message → SHOULD FIX\n    ├─ Incorrect config precedence → SHOULD FIX\n    ├─ Missing --help descriptions → SHOULD FIX\n    └─ NO → Is it an enhancement?\n        ├─ Could add --json output → NICE TO HAVE\n        ├─ Could add more examples in help → NICE TO HAVE\n        ├─ Could improve verbose logging → NICE TO HAVE\n        └─ Style preference → DON'T MENTION\n

CRITICAL REMINDERS

\n
\n

All code must follow project conventions in CLAUDE.md

\n
\n

(You MUST verify SIGINT (Ctrl+C) handling exists in CLI entry point)

\n

(You MUST verify p.isCancel() is called after EVERY @clack/prompts call)

\n

(You MUST verify exit codes use named constants - flag ANY magic numbers in process.exit())

\n

(You MUST verify parseAsync() is used for async actions, not parse())

\n

(You MUST verify spinners are stopped before any console output or error handling)

\n

Failure to catch these issues will result in CLIs that crash on Ctrl+C, have undocumented exit codes, and silently swallow errors.
