Developer Tools
14Agent SDK App Builder
Scaffold new Claude Agent SDK applications in TypeScript or Python, and verify existing ones against official SDK patterns before you ship.
Ralph Wiggum Autonomous Loop
Self-referential development loop that keeps Claude iterating on the same task until it hits a completion promise or an iteration cap — a Stop hook that blocks exit and re-feeds the same prompt.
PR Review Toolkit
Six specialist reviewers — comments, tests, error handling, type design, general quality, and simplification — each triggered by name or automatically based on what changed in the diff.
Security Guidance Review
Three-layer continuous security review for AI-generated code — instant regex warnings on edit, an LLM diff review at end of turn, and an agentic commit-time reviewer that traces data flow across files.
Vercel Analytics & Speed Insights Setup
Wire up Vercel Analytics, Speed Insights, and SPA routing rewrites into a React/Vite project in one pass — including the routing fix most people miss.
Automated PR Code Review
High-signal automated PR review using parallel agents with a validation pass that filters out false positives before anything gets posted.
Claude Model Migration Assistant
Migrate code and prompts between Claude models — update model strings, remove incompatible beta headers, and adjust prompts only for reported behavioral differences.
Claude Code Plugin Builder
End-to-end guided workflow for building Claude Code plugins — structure, commands, agents, skills, hooks, and MCP integration — with a validation checklist before you distribute.
Distinctive Frontend Design
Design lead guidance for building frontends that don't read as AI-generated — deliberate palette, typography, and layout choices grounded in the actual subject, with a built-in self-critique pass before you write code.
Explanatory Coding Mode
Get educational insights about implementation choices and codebase patterns as Claude works — formatted, codebase-specific commentary woven into the session, not a generic tutorial.
7-Phase Feature Development Workflow
Structured feature development that explores the codebase, asks every clarifying question up front, presents multiple architecture options with a recommendation, and runs a three-angle quality review before calling it done.
Learning Mode Coding Coach
Interactive coding mode that hands you the meaningful 5-10 line decisions — business logic, trade-offs, design choices — while Claude handles the boilerplate and explains the codebase as you go.
Git Commit & PR Automation
Three streamlined git workflows: commit with an auto-drafted message matching your repo's style, ship a full commit-push-PR in one step, and clean up branches deleted on the remote.
Hookify Guardrails
Create custom Claude Code guardrails with lightweight markdown rule files instead of hand-editing hooks.json — pattern matching, no restart required, rules live-load on the next tool call.
Marketing & Content
3SERP-Overlap Content Clustering
Design hub-and-spoke content architecture using actual Google SERP overlap — not keyword text similarity — with a full internal link matrix and cannibalization checks.
Blog-to-Social Publisher
Turn one blog post into an X thread, LinkedIn post, Medium article, and Dev.to RSS feed — zero dependencies, works in any repo type.
Evidence-Based GEO / AI Search Optimization Audit
Audit content for AI Overviews, ChatGPT, and Perplexity citability using primary-source evidence — including why llms.txt isn't the ranking lever most GEO advice claims it is.
Legal & Compliance
2Bulk Legal Document Review to Excel Matrix
Turn dozens or hundreds of contracts, NDAs, or leases into a single sourced Excel matrix — one row per document, one column per review question, color-coded risk flags.
Legal Memo Drafting Assistant
Draft structured, objective IRAC-format legal memoranda — question presented, brief answer, statement of facts, IRAC discussion, and a practical recommendation.
