* refactor(rules): restructure rules into common + language-specific directories - Split 8 flat rule files into common/, typescript/, python/, golang/ - common/ contains language-agnostic principles (no code examples) - typescript/ extracts TS/JS specifics (Zod, Playwright, Prettier hooks, etc.) - python/ adds Python rules (PEP 8, pytest, black/ruff, bandit) - golang/ adds Go rules (gofmt, table-driven tests, gosec, functional options) - Replace deprecated ultrathink with extended thinking documentation - Add README.md with installation guide and new-language template Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> * Fix installation commands for rules Updated installation instructions to copy all rules to a single directory. * docs: update README.md to reflect new rules directory structure Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> --------- Co-authored-by: Hor1zonZzz <Hor1zonZzz@users.noreply.github.com> Co-authored-by: Claude Opus 4.5 <noreply@anthropic.com>

TypeScript/JavaScript Coding Style
This file extends common/coding-style.md with TypeScript/JavaScript specific content.
Immutability
Use spread operator for immutable updates:
// WRONG: Mutation
function updateUser(user, name) {
user.name = name // MUTATION!
return user
}
// CORRECT: Immutability
function updateUser(user, name) {
return {
...user,
name
}
}
Error Handling
Use async/await with try-catch:
try {
const result = await riskyOperation()
return result
} catch (error) {
console.error('Operation failed:', error)
throw new Error('Detailed user-friendly message')
}
Input Validation
Use Zod for schema-based validation:
import { z } from 'zod'
const schema = z.object({
email: z.string().email(),
age: z.number().int().min(0).max(150)
})
const validated = schema.parse(input)
Console.log
- No
console.logstatements in production code - Use proper logging libraries instead
- See hooks for automatic detection
