Independent developer & publisher in Japan. I build practical tools and share field notes on AI agents, open source, media, and life after launch.

“34% left” means little without a pace.

I built QuotaTempo to compare weekly Codex and Claude capacity with an even-pace target in the Mac menu bar.

12-second demo, using example data. Free beta for Apple silicon:

A local health check needs a narrow boundary.

“In an AI agent workspace, choosing not to look is part of the design.”

I built codex-healthkit to inspect metadata, not transcripts or credentials.

A useful automation leaves evidence. What changed? Which action is confirmed? What is still uncertain? Clear answers matter more than a green success message. Notes from the field: https://t.co/11cxONSRIV

Cross-model review should remove copy-paste, not human judgment.

“A human needs to be in the loop. A human does not need to be the transport layer.”

Local-first is a practical choice. When a diagnostic tool can answer a question from metadata, it should not need your session contents to do it. That principle guides my open-source work. https://t.co/904JT0xhOi

“A reset is better used as a button that finishes work than one that starts it.”

My field notes on Codex banked resets, the 30-day expiry, and deciding when to spend one:

What breaks when AI agents run in production? I write field notes from a solo developer in Japan: what I built, what I measured, and what needed repair. https://t.co/11cxONSRIV

Weekly usage left didn't tell me what I could plan to use today. I built QuotaTempo to show WEEKLY LEFT beside TARGET NOW for Codex and Claude on macOS.

It's live on Product Hunt. If you try it, does this view help?

“The problem was never the reading. It was turning the same public page into something reusable.”

I built a CLI for public-page research. The original source remains the authority.

I build small, reviewable tools for AI operations. The goal is not more automation for its own sake; it is work that a person can inspect, understand, and safely continue. https://t.co/904JT0xhOi
