site →moskowitz labs— a web agency where ai does the building
Clients get a finished, live website — without the traditional agency timeline or price tag. AI handles research, design, copywriting, build, QA, and deployment. The output is indistinguishable from bespoke work. The timeline isn't.

github →captain— pirate-guided task orchestration for ai coding agents
A state machine skill for AI coding agents that breaks any complex task into lettered nodes, tracks progress on an ASCII helm, checkpoints to git at every step, and puts you in control of when to review, rewind, or redirect.

github →verylegit marketplace— productivity and personality plugins for ai coding agents
A curated plugin marketplace for AI coding agents. Skills include captain (task orchestration), debate (adversarial plan review), wtf (angry quick questions), tldr (brutal simplification), bear-notes, iOS simulator control, and more.

github →expert— translates novice prompts into expert-level instructions
A Claude Code plugin that sits between you and the agent. You say "make it secure"; Claude receives a STRIDE attack-surface enumeration with severity ranking. The translation is shown to you, so you learn the vocabulary while you work.

github →write-like-you— mines your imessages into a personalized voice skill
Run it once and it reads your message history, analyzes acknowledgment style, humor, punctuation habits, and register shifts, confirms the read with you, then generates a Claude Code skill that writes in your voice — for LinkedIn, Slack, READMEs, anywhere.

github →imessage-mcp— read-only mcp server for imessage on macos
Exposes your local iMessage database over the Model Context Protocol with automatic contact-name resolution across all AddressBook stores. Works with Claude Code, Claude Desktop, Cursor, and Codex.

github →swipeclean— clean your gmail inbox by swiping through senders
Native iOS and Android app — no backend. Scans your last 6 months of Gmail, groups by sender, scores using heuristics and on-device ML, and lets you swipe left to block or right to keep. Blocked senders are auto-filtered to trash.
