CLI Design Approach Review | Generated by AI
Question: Is my CLI design approach correct, especially in terms of simplicity and flag usage?
Answer:
Yes, your approach makes a lot of sense, especially for personal or power-user tools. Here are the key points that stand out and why they work well:
-
Minimizing Flags
- Letting commands work without requiring flags by default (

--diror--promptare there for advanced use, which balances simplicity and flexibility.
- Letting commands work without requiring flags by default (
-
Command Naming & Hierarchy
- Using clear verbs (
note,screenshot,obfuscate) communicates intent instantly. - Subcommands and arguments are structured logically (
ww note screenshot-log,ww note obfuscate <file>), which scales as you add more functionality.
- Using clear verbs (
-
Defaults for Instant Use
- Commands that work immediately with reasonable defaults (like
ww screenshotcapturing instantly to a default folder) reduce cognitive load. Users don’t have to think if they just want the most common outcome.
- Commands that work immediately with reasonable defaults (like
-
Documentation & Feedback
- Your CLI prints concise usage instructions and examples after execution. This is very user-friendly, especially for new users.
- Including both “old” and “new” command references helps users transition without breaking habits.
-
User Consideration
- You’re thinking about the difference between your personal use vs general users (

Real-World Practices
- Many modern CLIs (e.g.,
git,aws cli,gh) follow this philosophy: common actions should be simple, extra options available when needed. - Your design is in line with this principle.
- Many modern CLIs (e.g.,
⚡ Suggestion:
- Keep the core commands minimal and predictable.
- Make advanced flags discoverable via
--help. - Consider optional confirmation for destructive commands (like obfuscate) when going beyond personal use.
Overall, your design looks solid and user-friendly. It’s exactly the kind of CLI that power users love—fast, minimal, and flexible.
