D3.js plugins

Build and manage end-to-end data analytics workflows: implement A/B testing with statistical rigor, design reliable analytics tracking, create interactive D3.js visualizations, architect scalable database schemas, and optimize SQL for cloud-native databases.

Assess and produce Tufte-principled data graphics: score existing charts against nine criteria, compute lie factor, detect chartjunk, and generate minimal-ink SVG/HTML charts with proper axes and direct labels.

Apply 33 structured reasoning frameworks — Bayesian analysis, root cause investigation, decision matrices, pre-mortems, and strategic planning — directly inside Claude Code to improve forecasts, valuations, architectural decisions, and problem-solving rigor.

Automate X/Twitter fully without API keys: scrape profiles/tweets/followers/media, post threads/polls/DMs, manage lists/follows/blocks/mutes, analyze engagement/trends/networks/competitors, monitor growth/monetization, and build AI agents via Puppeteer browser scripts, CLI, REST APIs, and 80+ MCP tools.

A founder operating system that turns GitHub into a command center for running a business with AI agents — manages departments, weekly planning, retros, product roadmaps, competitive analysis, media production with HTML drafts, and Telegram bot operations through structured workflows and automated issue tracking.

Perform deep research on videos and web content using Gemini, then automatically generate structured reports, knowledge graphs, and explainer videos with narration and AI-generated visuals.

Runs a team of autonomous agents that implement features via TDD, review code with adversarial critiques, and maintain living documentation — all while enforcing project conventions for Go, SQLite, and git workflows.

AI-powered job search companion that ingests resumes, scores ATS compatibility, searches and ranks listings, tracks applications, prepares for interviews, and generates outreach copy, cover letters, and negotiation messages — all within a feedback loop that learns from outcomes

Provides a library of reusable AI agent skills for automating business tasks including competitive intelligence monitoring, lead qualification, proposal generation, and content creation, with integrations for Baidu's PaddlePaddle and ERNIE platforms.

Generate visuals across 11 channels including raster, SVG, web, interactive, video, terminal, diagrams, and infographics while enforcing brand tokens, 8:1 contrast minimum, custom dimensions, and style guides. Critique produced PNG/JPG/SVG/PDF artifacts with a vision-model agent that evaluates design principles (Tufte/Bertin/Gestalt), channel anti-patterns, and brand compliance, providing evidence-based PASS/NEEDS REVISION/FAIL verdicts.

Manage your personal and professional relationships, projects, and communications entirely locally with AI-powered insights from meeting transcripts, emails, and calendar data. Automate follow-ups, track commitments, generate dashboards, and search across all your data using natural language.

Turn document corpora into cross-domain knowledge graphs with pre-built schemas for drug discovery, contract analysis, clinical trials, and FDA product labels. Extract structured entities and relations, explore graphs via an interactive workbench with LLM-powered Q&A, and export to standard formats. Enrich knowledge via PubMed, PubChem, and epistemic analysis.

Audit and improve visual design of websites, UIs, and documents against 11 research-backed principles including layout, typography, color, hierarchy, whitespace, and accessibility — with WCAG 2.2 AA checks, VisAWI scoring, and actionable fix suggestions.

Build Svelte-first interactive frontends with animations, 3D/WebGL, scrollytelling, data visualization, and design systems. Agents assist with creative direction, technical architecture, visual design decisions, and UX research. Includes a safety hook to prevent overwriting canonical project files.

Engineer Svelte-first interactive frontend experiences with animations (GSAP, Lenis), 3D/WebGL (Threlte), scrollytelling, data visualization (D3, Layer Cake), and headless UI (Melt), guided by creative direction, design system implementation, and UX research, with performance rules and bun tooling.

Generate responsive D3.js v7 visualizations like bar charts, scatter plots, treemaps, force-directed graphs, Sankey diagrams, and more in standalone HTML, HTML+JS, or React single-screen layouts for rapid data visualization prototyping and deployment.
