Codex MCP tool reference. Supplemental parameter docs for codex tool (tuannvm/codex-mcp-server).

Generates Dockerfile for application containerization and deployment. Defines multi-stage build process with Node.js build stage and nginx serving stage for production deployment.

Configure multi-platform deployment for FastAPI applications including Docker containerization, Railway, DigitalOcean App Platform, and AWS deployment. Use when deploying FastAPI apps, setting up production environments, containerizing applications, configuring cloud platforms, implementing health checks, managing environment variables, setting up reverse proxies, or when user mentions Docker, Railway, DigitalOcean, AWS, deployment configuration, production setup, or container orchestration.

Use when creating or developing anything, before writing code or implementation plans - refines rough ideas into fully-formed designs through structured Socratic questioning, alternative exploration, and incremental validation

Analyze and map code structure, data flow, and dependencies in legacy codebases. Use for understanding call stacks, dependency trees, side effects, risk profiles, and generating Mermaid diagrams. Ideal for legacy codebases with zero tests.

Audit all filename and naming conventions in the codebase against CLAUDE.md standards and common patterns. Use when user asks to check naming conventions, audit filenames, find naming inconsistencies, or validate file naming patterns.

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.

Query the China Biographical Database (CBDB) API to retrieve comprehensive biographical data about historical Chinese figures. Use this skill when searching for information about Chinese historical figures, scholars, officials, or literary figures from the 7th century BCE through the 19th century CE. Applicable for queries about biographical details, social relationships, official positions, or when users mention specific Chinese names or CBDB person IDs.

Documentation lookup using Context7 MCP server. Use when needing up-to-date documentation for any library, crate, framework, or API. Always use this for Rust crates, npm packages, Python libraries, or any external dependency documentation.

Coffi FFI library for calling native C code from Clojure via Panama FFM API (JDK 22+). Use when: wrapping native C libraries, calling native functions, working with off-heap memory and arenas, etc.

Understand the already-done code, including best practices, linting, structure, patterns, etc, by reading it smartly, catching up the necessary context to implement features, or fix bugs.

Designing Slash Commands for Claude Code. Create and optimize slash commands with proper argument parsing, tool permissions, and agent orchestration. Use when building workflow entry points, automation commands, or user-facing shortcuts.

Write self-documenting code with clear structure and naming, adding minimal concise comments only to explain complex logic sections, avoiding temporal comments about changes or fixes. Use this skill when writing code in any file across the codebase to ensure proper commenting practices. Use this skill when deciding whether to add comments to functions, classes, or complex algorithms, when reviewing existing comments for relevance and evergreen quality, or when refactoring code to be more self-explanatory. Use this skill for Python files, JavaScript/TypeScript files, or any programming language where code documentation is needed. Use this skill when establishing documentation standards, avoiding over-commenting, or removing outdated temporal comments about recent changes.

Audit and refactor CSS to comply with Game Loopers design system and BEM methodology

This skill should be used when debugging web applications, diagnosing page errors, inspecting console output, or capturing screenshots of pages. It provides Chrome DevTools Protocol (CDP) automation via the chromectl.py script for collaborative or automated browser debugging.

Complete Metalama documentation for aspect-oriented programming in C#. Use when writing aspects, templates, fabrics, or meta-programming code with Metalama.

ESLint, Prettier, and StyleLint configuration standards for JavaScript code quality and formatting, including flat config setup, rule management, and build integration

Assistant for creating, editing, and debugging reactive Python notebooks with marimo.
