Claude Skill Bash

Apply comprehensive bash scripting standards including main function pattern, usage documentation, argument parsing, dependency checking, and error handling. Triggers when creating/editing .sh files, bash scripts, or discussing shell scripting, deployment scripts, automation tasks, or bash conventions.

Set up professional Quarto documentation projects with PDF output via LaTeX templates. Use this skill when the user wants to create a Quarto project, set up a documentation project with PDF output, configure LaTeX templates for Quarto, render markdown to professional PDF, or asks about Quarto document setup. Triggers on mentions of "quarto", "pdf template", "latex template for documents", "documentation project setup", or "professional PDF from markdown".

REST API design principles — resource modeling, URL structure, versioning, collections, sub-collections, ownership, operations, reports, methods and status codes. Use when designing, adding, or reviewing REST API endpoints, or deciding how a domain concept maps to resources and URLs.

Build a high-quality Claude Code skill from one or more PDFs using vision-based page-by-page extraction. Use when converting reference material (technical manuals, certificates, policy documents, magazines, books, regulations) into a skill with structured markdown chapters, bundled diagrams, and a navigable SKILL.md. Triggers on requests like "convert this PDF to a skill", "make a skill from these manuals", "build a knowledge base from these documents", "vision-extract this PDF into a skill", or when the user has decided to turn PDF reference material into a Claude Code skill.

Author print-quality Mermaid architecture and ops diagrams (system sketches, deployment pipelines, monitoring and data-flow maps) using a semantic color system and a mandatory render-and-inspect loop. Use when creating, styling, or reviewing Mermaid diagrams; when asked for an architecture diagram, system sketch, or flowchart destined for documentation (Quarto/pandoc/PDF, GitHub README, wikis); or when a Mermaid diagram renders ugly, clipped, or unreadable. Covers verified pipeline-specific gotchas (Quarto vs mermaid-cli) and their workarounds.

General software architecture principles — extending the existing domain model instead of creating parallel per-feature vocabularies, separating generic capability from feature-specific judgment, naming from the ubiquitous language, and ranking model coherence above change isolation. Use when designing, architecting, or reviewing features, APIs, services, or data models — any time new types, endpoints, resources, or concepts are about to be introduced into an existing system.
