Tools

Small single-file HTML tools, mostly built with help from LLMs. Each one is a plain .html file you can read with View Source.

The colophon lists every tool's commit history, with links to the chats and agent sessions that wrote them. The code lives in mwarkentin/tools.

Infrastructure

• Cron explainer: describe a cron expression in plain English and list its next runs in Toronto time, or any other time zone
• Kubernetes quantities: convert and add up CPU and memory quantities like 500m and 2Gi

Text and logs

• Log prettifier: turn pasted JSON or logfmt logs into readable lines, filter them by level, and copy the result as Markdown
