Keep core flows stable; enable extension via small classes.
Use a base class that defines the algorithm skeleton; subclasses override hooks.
abstract class Importer {
final public function handle(string $path): void {
$rows = $this->load($path);
$data = $this->normalize($rows);
$this->validate($data);
$this->save($data);
}
abstract protected function load(string $path): array;
protected function normalize(array $rows): array { return $rows; }
protected function validate(array $data): void {}
abstract protected function save(array $data): void;
}
Define an interface; register implementations; select by key/config.
interface PaymentGateway { public function charge(int $cents, string $currency): string; }
final class StripeGateway implements PaymentGateway { /* ... */ }
final class BraintreeGateway implements PaymentGateway { /* ... */ }
final class PaymentsRegistry {
/** @param array<string,PaymentGateway> $drivers */
public function __construct(private array $drivers) {}
public function for(string $key): PaymentGateway { return $this->drivers[$key]; }
}
Prefer adding a class over editing switch statements. Test implementations in isolation.
development
Use this skill any time a spreadsheet file is the primary input or output. This means any task where the user wants to: open, read, edit, or fix an existing .xlsx, .xlsm, .csv, or .tsv file (e.g., adding columns, computing formulas, formatting, charting, cleaning messy data); create a new spreadsheet from scratch or from other data sources; or convert between tabular file formats. Trigger especially when the user references a spreadsheet file by name or path — even casually (like "the xlsx in my downloads") — and wants something done to it or produced from it. Also trigger for cleaning or restructuring messy tabular data files (malformed rows, misplaced headers, junk data) into proper spreadsheets. The deliverable must be a spreadsheet file. Do NOT trigger when the primary deliverable is a Word document, HTML report, standalone Python script, database pipeline, or Google Sheets API integration, even if tabular data is involved.

Review UI code for Web Interface Guidelines compliance. Use when asked to "review my UI", "check accessibility", "audit design", "review UX", or "check my site against best practices".
tools
Suite of tools for creating elaborate, multi-component claude.ai HTML artifacts using modern frontend web technologies (React, Tailwind CSS, shadcn/ui). Use for complex artifacts requiring state management, routing, or shadcn/ui components - not for simple single-file HTML/JSX artifacts.
