Scripting

Advanced types, strict mode, type safety

Understand and utilize the project's technology stack including NestJS, Next.js, Prisma, PostgreSQL, and TypeScript. Use this skill when making technology decisions, when choosing libraries or packages, when understanding framework-specific patterns, or when configuring development tools. This includes NestJS with feature-based modular architecture, Next.js 15 with App Router, Prisma ORM for database access, PostgreSQL, TypeScript with strict mode, pnpm for package management, Turborepo for monorepo orchestration, and shared workspace packages. Apply when setting up new features, choosing dependencies, or understanding the overall system architecture.

Runs Python scripts and manages projects using uv. Use when asked to run a python script, execute python code, run pytest, or install packages. Always uses uv instead of pip or bare python.

This skill should be used when working with TypeScript code, including type definitions, type inference, generics, utility types, and TypeScript configuration. Provides comprehensive knowledge of TypeScript patterns, best practices, and advanced type system features.

Use when converting strategy documentation to code - translates markdown strategy docs into Python functions (for backtesting frameworks like Backtrader) and TradingView Pine Script. Activates when user says "convert to Python", "generate Pine Script", "code this strategy", mentions "backtest", or uses /trading:translate command.

Use when user says "verify code", "check acceptance criteria", "is story ready", or when a story at verifying stage needs execution-based verification - runs tests, checks acceptance criteria, verifies user journeys, generates pass/fail report with evidence, and updates story status.

Expert guidance for Python testing that analyzes your existing setup and provides evidence-based recommendations. I'll examine your current tests, configurations, and dependencies before suggesting changes. Use when writing tests, improving coverage, debugging issues, or optimizing testing setup.

Typescript and JavaScript protocols and code styles

DX V3 workflow system, skills, slash commands, Beads issue tracking, and Serena code navigation.Handles skill creation, command configuration, workflow automation, and Beads/Serena integration.Use when working with developer workflows, creating skills, configuring commands, or Beads/Serena integration,or when user mentions DX improvements, skill creation, workflow automation, developer experience,"skill not found" errors, "command not working" errors, meta-workflow, DX tooling, or V3 system.

Expert Ruby on Rails architect for reviewing existing Rails applications, suggesting architectural improvements, and designing new features following modern Rails best practices. Use when working with Rails apps, designing Rails features, or reviewing Rails architecture. Based on 37signals/Basecamp production patterns.

Automate GitHub repository setup with CI/CD workflows, issue templates, Dependabot, and CodeQL security scanning.Includes 12 production-tested workflows and prevents 18 errors: YAML syntax, action pinning, and configuration.Use when: setting up GitHub Actions CI/CD, creating issue/PR templates, enabling Dependabot or CodeQL scanning,deploying to Cloudflare Workers, implementing matrix testing, or troubleshooting YAML indentation, action versionpinning, secrets syntax, runner versions, or CodeQL configuration.Keywords: github actions, github workflow, ci/cd, issue templates, pull request templates,dependabot, codeql, security scanning, yaml syntax, github automation, repository setup,workflow templates, github actions matrix, secrets management, branch protection, codeowners,github projects, continuous integration, continuous deployment, workflow syntax error,action version pinning, runner version, github context, yaml indentation error

Detect common security vulnerabilities in code. Covers OWASP patterns, SQL injection, bare excepts, shell injection. Framework-agnostic.

This skill should be used when writing, debugging, reviewing, or discussing Go (Golang) code. Provides comprehensive Go programming expertise including idiomatic patterns, standard library, concurrency, error handling, testing, and best practices based on official go.dev documentation.

Physics-inspired story analysis system that treats narrative as trajectories through dimensional space. Tracks dimensions like intimacy, trust, power, and stakes to calculate tension, validate pacing, and diagnose story problems. Genre-aware with formulas for romance, thriller, mystery, and fantasy. Use when analyzing story structure, engineering tension, validating character arcs, diagnosing pacing issues, or generating dimensional targets for scenes.

TypeScript testing strategies and type-safe test practices

Orchestrate tasks across multiple AI providers (Claude, OpenAI, Gemini, Cursor, OpenCode, Ollama). Use when delegating tasks to specialized providers, routing based on capabilities, or implementing fallback strategies.

Use this skill when creating or refining custom Claude Code slash commands. Slash commands are user-invoked reusable prompts that can accept arguments, reference files, and execute bash operations. Helps design command syntax, argument handling, file references, bash execution, and frontmatter configuration. Automatically invoked when user requests "create a command", "make a slash command", "add a /command", or mentions custom command development.

Generate, edit, or transform images with Gemini Nano Banana using bundled Python scripts (Flash or Pro) including aspect ratio, resolution, image-to-image edits, logo overlays, and reference images. Use when users request image generation, image edits, image-to-image transformations, logo placement, or specific aspect ratios or resolutions.

This skill should be used when the user asks to "create a prompt", "optimize a prompt", "improve this prompt", "engineer a prompt", "prompt engineering best practices", "make this prompt better", "recommend a model", "which model should I use", "best model for", "GPT vs Claude", "Opus vs Sonnet", "Haiku vs Sonnet", "analyze prompt quality", "fix my prompt", "prompt for Claude", "prompt for GPT", or needs help with prompt engineering techniques, model selection, or prompt optimization for any LLM (Claude Opus/Sonnet/Haiku 4.5, GPT 5.1/Codex, Gemini Pro 3.0).
