Welcome to my digital playground. I like optimizing things: mechanical keyboards, monitor setups, prompts, the occasional elegant code solution. Lately most of that energy goes into tooling for Anthropic's Claude, with prompt optimizers grounded in official docs instead of vibes (ironic for a vibe-coder, I know), and a Firefox extension that makes claude.ai a nicer place to live.

| Project | What it does | Tech |
|---|---|---|
| 🧠 Claude Fable 5 Prompt Optimizer 🆕 | A claude.ai Project that turns any raw prompt into a Fable-5-ready one: 43 source-backed rules, complexity routing and API parameter recommendations, grounded entirely in official Anthropic docs. | AI Prompt Engineering |
| ⚡ Claude Opus 4.8 Prompt Optimizer | The same idea tuned for Opus 4.8: 11 rules, complexity-based routing and a hard prompt: trigger that rewrites raw input into production-ready, XML-structured prompts. |

| 🧭 Claude Voyager | A Firefox extension that upgrades claude.ai with folders, a prompt library, a conversation timeline and chat export. | TypeScript Firefox |
Earlier optimizer editions (Opus 4.7 · Opus 4.6) and a drawer full of Firefox extensions (Fleets Enhanced, YouTube Comment Timeline, Kleinanzeigen Filter) live in the full repo list.
⭐ Stars make my day, 🐛 issues make the tools better, and 🔧 PRs make my week. All three are very welcome.
