- Zod schemas for runtime validation (`src/models/schemas.ts`)

-## Command Design Principles
+## Design Principles

-**Keep commands minimal.** Avoid proliferating commands. One command per concept.
-
- Use a single command with arguments/modes instead of multiple similar commands
- Example: `/config` opens permission mode selection. No need for `/sacrifice`, `/safe`, `/confirm`, etc.
- Before adding a new command, consider if existing commands can be extended

 ## Code Principles

-| Principle | Criteria |
-|-----------|----------|
+| Principle | Guideline |
+|-----------|-----------|
 | Simple > Easy | Prioritize readability over ease of writing |
 | DRY | Extract after 3 repetitions |
-| Comments | Why only. Don't explain What/How |
-| Function size | One responsibility per function. ~30 lines target |
-| File size | ~300 lines as guideline. Be flexible per task |
-| Boy Scout | Leave touched areas slightly better |
+| Comments | Why only. Don't write What/How |
+| Function size | One function, one responsibility. ~30 lines |
+| File size | ~300 lines as guideline. Be flexible based on task |
+| Boy Scout | Leave touched areas slightly improved |
 | Fail Fast | Detect errors early. Don't swallow them |

 **When in doubt**: Choose Simple. Abstraction can come later.

 **Follow language/framework conventions:**
- Write Pythonic Python, Kotlinic Kotlin
- Use framework recommended patterns
- Prefer standard practices over custom approaches
+- Be Pythonic in Python, Kotlin-like in Kotlin
+- Use framework's recommended patterns
+- Choose standard approaches over custom ones

 **Research when unsure:**
- Don't implement based on guesses
- Check official documentation, existing code
+- Don't implement by guessing
+- Check official docs, existing code
 - If still unclear, report with `[BLOCKED]`

 ## Structure Principles

 **Criteria for splitting:**
- Has its own state -> Separate
- UI/logic over 50 lines -> Separate
- Has multiple responsibilities -> Separate
+- Has its own state → Separate
+- UI/logic over 50 lines → Separate
+- Multiple responsibilities → Separate

 **Dependency direction:**
- Upper layers -> Lower layers (reverse prohibited)
+- Upper layers → Lower layers (reverse prohibited)
 - Data fetching at root (View/Controller), pass to children
 - Children don't know about parents

 **State management:**
- Contain state where it's used
- Children don't modify state directly (notify parents via events)
- State flows unidirectionally
+- Keep state where it's used
+- Children don't modify state directly (notify parent via events)
+- State flows in one direction

 ## Prohibited

- **Overuse of fallback values** - Don't hide problems with `?? 'unknown'`, `|| 'default'`
+- **Fallback value overuse** - Don't hide problems with `?? 'unknown'`, `|| 'default'`
 - **Explanatory comments** - Express intent through code
 - **Unused code** - Don't write "just in case" code
 - **any type** - Don't break type safety
- **Direct mutation of objects/arrays** - Create new with spread operator

- **Actually run it**: Don't just look at files, execute and verify
- **Compare against requirements**: Re-read original task requirements, check for gaps
- **Don't take at face value**: Don't trust "complete" claims, verify yourself
- **Be specific**: Clearly state "what" is "how" problematic
