Claude Skills by krafteq

Add --json flag to CLI commands for machine-readable output on stdout. Generic pattern for any CLI tool, enabling piping to jq and CI/CD integration while keeping human-readable output on stderr.

Add shell completion support via a 'completion' subcommand for bash, zsh, and fish. Generic pattern for any Commander.js CLI, with static and dynamic completion examples.

Add zod schema validation for CLI options and YAML/JSON config files. Generic pattern for runtime validation with type-safe parsing and clear error messages in any Commander.js CLI.

Set up @changesets/cli for semantic versioning, CHANGELOG generation, and npm publishing in a monorepo or single package. Covers init, config, contributor workflow, GitHub Actions release automation, and npm provenance.

Add automatic CI/CD environment detection using ci-info package. Generic pattern for any CLI tool that needs to adapt behavior (prompts, output, integrations) based on whether it's running in CI.

Polish CLI user experience with @clack/prompts for interactive flows, update-notifier for version awareness, and enhanced Commander.js help text with examples and colors. Generic patterns for any Node.js CLI.

Implement a structured error class hierarchy with actionable messages, proper exit codes, debug mode via env var, and bug report hints on unexpected errors. Generic pattern for any CLI tool or Node.js application.

Set up GitHub Actions CI pipeline with test, lint, type-check, and build jobs for a Node.js/TypeScript project. Includes output grouping, error annotations, and job summary patterns.

Set up tsup (esbuild-based bundler) for a TypeScript package. Use when you need single-file bundled output, faster builds, and better startup time for Node.js CLIs or libraries. Covers tsup config, bin entry point, package.json scripts, and keeping tsc for type-checking only.

Set up Vitest for a TypeScript project, or migrate from Jest. Use for faster test execution, native ESM/TypeScript support, and Jest-compatible API. Covers config, dependency swaps, and test file updates.

Guide for creating effective skills. This skill should be used when users want to create a new skill (or update an existing skill) that extends Claude's capabilities with specialized knowledge, workflows, or tool integrations.

Patterns for writing comprehensive Vitest test suites in TypeScript projects. Covers shared test utilities, vi.mock for module mocking, fixture directories, provider/adapter testing, and state management testing. Tier - generic.

InfraGlue (ig) — CLI tool for managing Infrastructure as Code (IaC) monorepos. Orchestrates Terraform and Pulumi workspaces with dependency resolution, output injection, environment management, drift detection, and state reconciliation. Use this skill when working with ig.yaml configs, ig CLI commands, or multi-workspace Terraform/Pulumi infrastructure projects. Keywords: terraform, pulumi, infrastructure, IaC, monorepo, workspace, ig, infraglue, drift, plan, apply, destroy, import, export, r...
