Incrementally improve type safety by replacing string literals with enums, narrowing `any` types, and using shared types. Works in small verified batches. Preserves functionality while improving code quality.

This skill covers security hardening for serverless compute platforms including AWS Lambda, Azure Functions, and Google Cloud Functions. It addresses least privilege IAM roles, dependency vulnerability scanning, secrets management integration, input validation, function URL authentication, and runtime monitoring to protect against injection attacks, credential theft, and supply chain compromises.

pjt222

Apply the fail-early (fail-fast) pattern to detect and report errors at the earliest possible point. Covers input validation with guard clauses, meaningful error messages, assertion functions, and anti-patterns that silently swallow failures. Primary examples in R with general/polyglot guidance. Use when writing functions that accept external input, adding input validation before CRAN submission, refactoring code that silently produces wrong results, reviewing PRs for error-handling quality, or hardening internal APIs against invalid arguments.

Nushell Craft

hustcer

Comprehensive Nushell scripting best practices, idioms, security, and code review. Use when writing, reviewing, auditing, or refactoring Nushell (.nu) scripts to ensure they follow idiomatic patterns, naming conventions, proper type annotations, functional style, security best practices, and Nushell's unique design principles. Triggers on tasks involving Nushell scripts, modules, custom commands, pipelines, or any .nu file editing. Also helps convert Bash/POSIX scripts to idiomatic Nushell. Covers the type system, data manipulation, performance optimization, security hardening, script review, and common gotchas.
