Tools I needed, built until they held up, then published. Mostly agent skills. No account, no API key, runs on your machine.

English | 繁體中文

Everything here started as a problem on my own machine, and got published once it survived real use rather than a demo.

Open SKILL.md standard — they work in Claude Code and Codex.

• audio-tldr — any video, audio, or podcast into key takeaways. Whisper runs locally; transcripts are cached by content hash, so the same source is never transcribed twice.
• parcel-kau-a — Taiwan parcel tracking. Six couriers read straight from their public pages, because Taiwan has no free tracking API.
• audio-leveler — speech audio whose volume keeps moving, levelled. It measures the loudness first, so the fix matches the actual fault instead of a copy-pasted recipe.

• sharedoc-mcp — turns agent-generated Markdown into a link you can hand to someone. GitHub gists today, your own server tomorrow.

• ChronosUI — observability for the schedulers you already run, crontab and Windows Task Scheduler. It doesn't replace them; it shows you run history, captured output, and durations.

• Your machine, your data. Local transcription, local audio processing, public pages read directly. Where a service is involved, self-hosting is a supported path, not an afterthought.
• No signup wall. No API key and no account for the tools that don't need one.
• Open standards over lock-in. Open SKILL.md for the skills, MCP for the server, your existing scheduler for ChronosUI.
• Docs that say what a tool doesn't do. Every README scopes its claim, states the caveats inline, and ships in English and 繁體中文.
