## Open source & side projects
- [Claude Pet](https://github.com/uygnoey/claude-pet): A desktop pet that floats on your screen and watches your Claude token usage. Runs on macOS (native AppKit, Apple-notarized) and Windows, with a usage pill showing session, weekly and per-model usage plus reset times.
- [archify](https://github.com/tt-a1i/archify/pull/457): Contributed a Viewer UI translation layer to an agent skill for architecture, workflow and sequence diagrams, so new languages can be added as data without touching the renderer (merged into dev).
- [llmwiki_json](https://github.com/uygnoey/llmwiki_json): A personal knowledge wiki maintained by AI with JSON as the source of truth. Following Karpathy’s LLM Wiki pattern, the LLM integrates knowledge once and keeps it updated instead of re-assembling sources for every question.
- [skills-from-claude-blog](https://github.com/uygnoey/skills-from-claude-blog): Pulls official posts from claude.com/blog and turns each one into the Claude Code spec artifacts that fit it. A batch job keeps picking up new posts.
- **ai-social-batch-publisher**: A batch pipeline that takes AI posts from the Claude blog conversion repo and DeepLearning.AI’s The Batch, and uses a local Codex as the worker to turn them into card news and short-form video. Codex now posts them automatically to Instagram @ai.info.from.officials.
