Engineering notes on AI agents, developer tools, Kubernetes, and open source.
html-video is an open-source project from the Open Design team. It lets coding agents understand content, build storyboards, express frames with HTML/CSS, and render real MP4 videos locally through Chromium and ffmpeg.
html-ppt-skill is an AgentSkill for generating professional HTML presentations with themes, layouts, animations, and presenter mode using pure static HTML/CSS/JS.
OpenViking, Mirage, and SkillOpt show that AI agent systems are moving beyond model calls toward context databases, virtual filesystems, and optimizable skills.
GitHub Copilot is moving to usage-based billing, OpenRouter has launched Guardrails, and projects like AgentBudget point to a broader shift from subscription-style AI usage to metered, governed agent workflows.
