## Core rule

Always create new objects and arrays with the spread operator; never mutate directly.

## Execution Phases

1. **Check scope** — This skill is the shared floor; for React, backend architecture or API design, prefer the narrower dedicated skill.
2. **Core principles** — Put readability first and follow KISS, DRY and YAGNI, avoiding over-engineering and premature optimisation.
3. **TS/JS standards** — Use descriptive variable names and verb-noun function names, stay immutable, handle errors, parallelise with Promise.all, and avoid any.
4. **Structure and tests** — Follow REST and a consistent response shape, validate input with zod, name files by convention, comment the why, and write AAA tests with descriptive names.
5. **Detect code smells** — Look for functions over 50 lines, nesting 5+ levels deep and magic numbers; fix with smaller functions, early returns and named constants.

## Permissions (summarised from SKILL.md)

| Capability | Needed | Details |
|---|---|---|
| File writes | Required | Writes or refactors project code to follow these conventions. |
| Command execution | Not required | A conventions reference; it does not call for running commands. |
| Network outbound | Not required | No network access needed. |
