Toolkit
Skills, tools, and MCP servers I use with Claude Code
Skills
Learning Opportunities
Offers optional 10-15 minute learning exercises after significant work like new files, schema changes, or refactors. Uses prediction, retrieval practice, and spaced repetition so you retain what you just built rather than passively accepting the output.
Education
Frontend Design
Creates distinctive, production-grade frontend interfaces. Generates polished code that avoids the generic look of most AI-generated UIs. I use it when building web components and pages from scratch.
Design
Terraform
Teaches Claude Code to write proper Terraform. Covers module structure, naming conventions, state management, and common patterns so you get idiomatic IaC instead of fighting with generated code.
Infrastructure
Improve Codebase Architecture
Scans a codebase for shallow modules, where the interface is nearly as complex as the implementation it hides, and presents the deepening opportunities as a visual HTML report. Pick one and it grills through the redesign with you, ranking each candidate by how much friction it removes.
Architecture
Domain Modeling
Builds and sharpens a project's ubiquitous language. Challenges fuzzy terminology, stress-tests concepts against concrete edge cases, and checks the stated rules against the actual code. Decisions land in a glossary and ADRs as they settle rather than after the fact.
Domain Modelling
Grill With Docs
A relentless interview that pokes holes in a plan or design before you commit to it. The ADRs and glossary entries fall out of the questioning as you go, so the documentation writes itself instead of being a separate job at the end.
Design
Tools
Spec Kit
Spec-driven development that works with 30+ AI coding agents including Claude Code. You describe what to build, it produces a constitution, spec, plan, and task breakdown, then drives the implementation. Built-in analyze and checklist commands catch gaps before you start coding.
Specifications
RTK
Token-optimized CLI proxy that sits between Claude Code and shell commands. Filters noise from tool output to cut token usage by 60-90% on dev operations like git, grep, and find. I run it system-wide via a hook so every Bash call goes through it automatically.
Efficiency
pentest-kit
Python library and pair of Claude Code harnesses for AI-assisted web pentesting against your own apps. One drives HexStrike for exploratory discovery, the other runs a deterministic regression suite. Both loop fresh Claude sessions until two consecutive clean rounds.
Security
MCP Servers
Playwright
Browser automation via the Model Context Protocol. Lets Claude navigate pages, take screenshots, click elements, fill forms, and inspect the DOM. I use it to visually review and iterate on site changes without leaving the terminal.
Browser
Chrome DevTools
Connects Claude to Chrome DevTools for full browser inspection. Console logs, network requests, performance traces, Lighthouse audits, and memory snapshots. Useful for debugging and auditing sites directly from the conversation.
Browser
HexStrike AI
MCP server that gives AI agents access to 150+ cybersecurity tools for automated pentesting, vulnerability discovery, and bug bounty work. Bundles network recon, web app testing, binary analysis, and cloud security into one interface.
