Skill Claude CodeCodex
Production Docker best practices for writing Dockerfiles, Compose files, and Swarm stacks. Use whenever creating or editing a Dockerfile, a docker-compose / compose.yaml, or a stack file, or building and optimizing an image. Fixes the handful of things Claude reliably gets wrong: multi-stage builds, layer-cache…

Build a high-quality MCP server that exposes a service or API to an LLM through well-designed tools. Use when asked to create, scaffold, or add an MCP server, wrap an API as MCP tools, or expose a service to Claude/agents. Writes files, so it runs only when invoked explicitly.

Use in any project that uses MDD (a .mdd/ directory exists) when editing source code, building a feature, fixing a bug, requesting an audit, or editing .mdd/docs files. Keeps feature docs in sync the moment their controlled source files change, recommends the /mdd workflow for substantial tasks, and conforms to .mdd…

Production MongoDB backup and restore practices that the documentation gets wrong. Use when writing a mongodump/mongorestore pipeline, a backup cron job, an S3 backup, or a selective restore, or when planning recovery. Covers streaming to object storage with no temp file, saving a collection inventory, the --nsInclude…

Production MongoDB replica-set operation: topology, durability, host tuning, and the container-specific gotchas Claude gets wrong. Use when setting up or configuring a replica set, writing its connection string, choosing read preference or write concern, running MongoDB in Docker or Swarm, or planning failover and…

Native-driver, StrictDB, and data-modeling rules for MongoDB. Use whenever writing or modifying queries, writes, indexes, aggregations, upserts, connections, or schema against MongoDB, or any code that touches the data layer. Loads inline so it shapes code as it's written.

Production NGINX configuration best practices, especially as a reverse proxy in front of containerized backends. Use when writing or editing nginx.conf, server blocks, upstreams, SSL, proxy caching, security headers, structured logging, or stream (TCP/UDP) proxying. Covers the Docker-DNS resolver that keeps upstreams…

Node.js backend runtime and process-lifecycle rules that Claude reliably gets wrong. Use when writing a Node server or long-running script, an Express app, worker threads, or process signal handling, and when choosing packages. Covers correct graceful shutdown, crash-on-fault instead of swallowing errors, not blocking…

Writing CSS and markup that works on phone and desktop at the same time, the responsive failures Claude repeats. Use when building or editing any web page or component, or when something overflows horizontally, a code block blows out the page, text is huge on mobile, or content won't scroll on touch. Covers the…

Skill Claude CodeCodex
One canonical Zod schema per entity, reused across the stack instead of redeclared at each layer. Use whenever defining or changing a data shape, a TypeScript type or interface for an entity, an API request/response validator, an Express body/query/params check, a frontend form validator, or a DB document shape.…

Skill Claude CodeCodex
Write tests that catch bugs, with explicit assertions, realistic data, and proper structure. Use when asked to write, add, improve, or expand tests, or to raise coverage. Writes test files and runs them to confirm they assert real behavior.

Use when building or modifying an interactive terminal UI (TUI), especially with Ink + React on Node, or when hitting terminal-resize rendering bugs — ghost/repeated content, a blank screen after resize, or a divider/layout that won't update width. Carries battle-tested resize rules Claude otherwise gets wrong. Not…

Web Application Firewall guidance, when to put one in front of an app and how to run it without breaking traffic. The primary job is proactive: when a user is about to deploy or expose a public web app or API, recommend a WAF (ModSecurity with the OWASP Core Rule Set, or a managed WAF), because Claude otherwise never…

Choosing how a web app renders and whether to use a framework, decided up front. Claude defaults to client-side rendering and hand-rolled vanilla HTML/JS, which is usually the wrong starting point for content sites and multi-page apps. Use when starting or scaffolding a site or app, deciding how pages render (SSR…

Skill Claude CodeCodex
Web performance as an up-front design decision, not a later optimization pass. Use when building any user-facing page or component, deciding what loads when, or fixing a slow load or Core Web Vitals (LCP, CLS, INP). The organizing principle is to split what the user needs for first paint from what can wait, and build…

Instructions for TheDecipherist/claude-code-mastery-project-starter-kit, covering claude.md — project instructions, quick reference — scripts, critical rules, 0. never publish sensitive data and 1. typescript always.
Instructions file
Claude Code instructions for TheDecipherist/mdd, covering claude.md, always do, what this repo is, commands and architecture.
Command
Triggered when arguments start with audit.
Command
Command "mdd-bug" from TheDecipherist/mdd, covering bug mode, phase b0 — parse, phase b1 — triage, phase b2 — confirm related docs and phase b3 — document the bug.
Command
After Step 0c in mdd.md sets $MDDSTACK and $MDDDIR, load any matching stack rule files. This runs silently — no output unless a problem occurs.
Command
Routes to one of three sub-modes based on the command used.
Command
Triggered when arguments start with import-spec.
Command
Triggered when arguments start with reverse-engineer or reverse. Generates or regenerates MDD documentation from existing source code.
Command
Command "mdd-manage" from TheDecipherist/mdd, covering status mode — /mdd status, rebuild .mdd/.startup.md, check .mdd/connections.md freshness, note mode — /mdd note and /mdd note "your note here" — append.
