Scripting

Complete quality validation workflow combining TypeScript checking, linting, tests, coverage, and build validation. Works with any TypeScript/JavaScript project. Returns structured pass/fail with detailed results for each check. Used in conductor workflows and quality assurance phases.

Chrome Manifest v3 extension development for Vigil Guard v2.0.0. Use for plugin development, content scripts, service workers, webhook integration with 3-branch detection, browser fingerprinting, and extension debugging.

DevContainer configuration for consistent development environments with Docker, multi-stage builds, non-root users, environment management, Docker-in-Docker support, and Python with uv. Activate when working with .devcontainer/, devcontainer.json, Dockerfile, or container-based development workflows.

Lint and test shell scripts using ShellCheck and BATS. Use when checking bash/sh scripts for errors, writing shell script tests, fixing ShellCheck warnings, setting up CI/CD for shell scripts, or improving bash code quality.

Fast, reproducible scientific Python environments with pixi - conda and PyPI unified

This skill should be used when the user asks to "create a slash command", "add a command", "write a custom command", "define command arguments", "use command frontmatter", "organize commands", "create command with file references", "interactive command", "use AskUserQuestion in command", "SlashCommand tool", "programmatic command invocation", "disable-model-invocation", "prevent Claude from running command", "debug command", "command debugging", "troubleshoot command", or needs guidance on slash command structure, YAML frontmatter fields, dynamic arguments, bash execution in commands, user interaction patterns, programmatic invocation control, debugging commands, or command development best practices for Claude Code.

Python development best practices and advanced patterns

UTF-8 JSON file I/O utilities to avoid Windows encoding issues (CP-1252 vs UTF-8)

Synchronizes tsconfig.json paths from package.json imports field. Ensures TypeScript resolves subpath imports (#imports) correctly during development.

This skill should be used when the user asks to "create a hook", "add a PreToolUse/PostToolUse/Stop hook", "validate tool use", "implement prompt-based hooks", "use ${CLAUDE_PLUGIN_ROOT}", "set up event-driven automation", "block dangerous commands", or mentions hook events (PreToolUse, PermissionRequest, PostToolUse, Stop, SubagentStop, SessionStart, SessionEnd, UserPromptSubmit, PreCompact, Notification). Provides comprehensive guidance for creating and implementing Claude Code plugin hooks with focus on advanced prompt-based hooks API.

Use when debugging regressions or identifying which commit introduced a bug - provides systematic workflow for git bisect with automated test scripts, manual verification, or hybrid approaches. Can be invoked from systematic-debugging as a debugging technique, or used standalone when you know the issue is historical.

Create and manage Jupyter notebooks for testing Adobe Edge Delivery Services (EDS) blocks interactively in the browser using the ipynb-viewer block. Interactive JavaScript execution, overlay previews with backdrop, direct ES6 imports. Use when creating notebooks, testing blocks with ipynb files in browser, generating overlay previews, or creating executable documentation.

Write RBS type annotations directly in Ruby source files using comment syntax. Use when adding types to Ruby code with rbs-inline.

This skill should be used when the user asks to "create a skill", "add a skill to plugin", "write a new skill", "improve skill description", "organize skill content", "SKILL.md format", "skill frontmatter", "skill triggers", "trigger phrases for skills", "progressive disclosure", "skill references folder", "skill examples folder", "validate skill", or needs guidance on skill structure, file organization, writing style, or skill development best practices for Claude Code plugins.

TypeScript/JavaScript testing practices with Bun's test runner. Activate when working with bun test, .test.ts, .test.js, .spec.ts, .spec.js, testing TypeScript/JavaScript, bunfig.toml, testing configuration, or test-related tasks in Bun projects.

Write standalone .rbs signature files to describe Ruby code. Use when creating type definitions for gems, libraries, or existing codebases without modifying Ruby source.

Creates bauplan data pipeline projects with SQL and Python models. Use when starting a new pipeline, defining DAG transformations, writing models, or setting up bauplan project structure from scratch.

Run TypeScript compiler type-checking (tsc --noEmit) to validate type safety and catch type errors. Returns structured output with error counts, categories (type/syntax/import errors), and affected files. Used for quality gates and pre-commit validation.

Shell scripting standards and safety practices. Use when language shell guidance is required or when selecting Shell as a thin wrapper or OS-near glue layer.

Discover project structure, package managers, test frameworks, and automation without hardcoded assumptions
