CLI Tools

Building Expo DevTools Plugins with CLI Interfaces for interacting with running Expo apps using agents.

Best practices for building CLI applications across languages. Covers CLI design principles (Unix philosophy, command structure, subcommands vs flags), argument parsing (required/optional args, flags, environment variables, config files, precedence), user interface (help text, version info, progress indicators, color output, interactive prompts), output formatting (human-readable vs machine-readable JSON/YAML, exit codes), error handling (clear messages, suggestions, debug mode), cross-platform considerations (paths, line endings, terminal capabilities), testing strategies (integration tests, output verification, exit codes), documentation (README, man pages, built-in help), and language-specific libraries. Activate when working with CLI applications, command-line tools, argument parsing, CLI utilities, argument handling, commands, subcommands, CLI frameworks, or building command-line interfaces.

Configures and integrates SAP Master Data Integration (MDI) service on SAP Business Technology Platform. Use when setting up MDI tenants, connecting applications (S/4HANA, SuccessFactors, Ariba, Fieldglass, etc.), configuring distribution models, SOAP APIs for business partners, extensibility, or troubleshooting master data replication. Covers One Domain Model integration, Business Data Orchestration, client authentication (OAuth2, mTLS), and security configurations.

SAP HANA Machine Learning Python Client (hana-ml) development skill. Use when: Building ML solutions with SAP HANA's in-database machine learning using Python hana-ml library for PAL/APL algorithms, DataFrame operations, AutoML, model persistence, and visualization. Keywords: hana-ml, SAP HANA, machine learning, PAL, APL, predictive analytics, HANA DataFrame, ConnectionContext, classification, regression, clustering, time series, ARIMA, gradient boosting, AutoML, SHAP, model storage

Type-safe API layer for TypeScript full-stack applications. Use when building APIs that need end-to-end type safety between client and server WITHOUT code generation. Ideal for Next.js, React, and Express apps where both frontend and backend are TypeScript. Choose tRPC over REST/GraphQL when you control both ends and want zero runtime overhead for type checking.

Extract comment locations from code files for analysis. Use when cleaning comments, auditing code documentation, or analyzing comment patterns. Supports Python, JavaScript, TypeScript, Go, Rust, Java, C/C++, Ruby, PHP, Shell scripts. Trigger terms - comments, extract comments, code comments, comment analysis, documentation audit, comment cleanup.

Auto-suggest modern CLI tool alternatives (bat, eza, fd, ripgrep) for faster, more efficient command-line operations with 50%+ speed improvements

List and get Linear issues via CLI (read-only operations)

Record Claude Code sessions with asciinema. TRIGGERS - record session, asciinema record, capture terminal, record claude, demo recording, record ASCII, ASCII terminal, terminal screen capture, shell screen capture, ASCII screen capture, screen recording. Generates ready-to-copy commands with dynamic workspace-based filenames.

Create configuration systems following VoiceMode and MCPro patterns. Use when building new Python projects that need flexible configuration with .env files, environment variables, CLI arguments, and cascading precedence. Implements dotenv-based config with Click CLI integration and helper functions for path expansion and boolean parsing.

This skill should be used when the user asks to "create ClickHouse user", "manage ClickHouse permissions", "test ClickHouse connection", "troubleshoot ClickHouse Cloud", or mentions ClickHouse Cloud credentials, API keys, or SQL user management.

Strategic CLI refactoring using Qwen 1.5B for extracting command modules from monolithic main() functions

Add clickable Creative Commons license and fullscreen icons to an existing MicroSim's control region. Use this skill when enhancing a MicroSim with navigation icons in the lower right corner. Adds approximately 40 lines of code for icon functionality.

Create and update Linear projects via CLI (write operations)

This skill should be used when optimizing, converting, or resizing images. Trigger when user mentions image optimization, HEIC/HEIF conversion, JPEG/PNG/WebP/AVIF processing, reducing image file size, or batch image processing. Uses sharp-cli as the primary tool.

Data fetching patterns for server/client components using fetch API, TanStack Query, useSuspenseQuery, apiRouteWrapper, and apiRequestWrapper. Use when implementing data loading, API calls, server functions, queries, mutations, API routes, or when the user mentions TanStack Query, useSuspenseQuery, apiRouteWrapper, apiRequestWrapper, tmdb-server-functions, or data fetching.

Enforce mandatory pre-action verification checkpoints to prevent pattern-matching from overriding explicit reasoning. Use this skill when about to execute implementation actions (Bash, Write, Edit, MultiEdit) to verify hypothesis-action alignment. Blocks execution when hypothesis unverified or action targets different system than hypothesis identified. Critical for preventing cognitive dissonance where correct diagnosis leads to wrong implementation.

Facet is a serde replacement for Rust using reflection. Use this skill when working with serialization, deserialization, CLI parsing, or any task where you'd normally use serde. Provides crate mappings (serde_json → facet-json, clap → facet-args, etc.) and usage patterns.

Optimize CLAUDE.md files and Skills for Claude Code CLI. Use when reviewing, creating, or improving system prompts, CLAUDE.md configurations, or Skill files. Transforms negative instructions into positive patterns following Anthropic's official best practices.

State-driven interactive animations with built-in state machines. Use when animations must REACT to user input (hover, click, drag), have multiple states/transitions, or respond to data values (progress bars, counters). Ideal for animated buttons, toggles, checkboxes, characters. For simple play/loop animations use Lottie instead.
