Vexilo

Hao Studio looked at Claude Code—the AI coding assistant everyone's losing their minds over—and said "you know what, most developers have no idea what this thing can actually do." So they built Vexilo, a field guide that turns Claude Code into an actual usable superpower. We're talking 31 pre-built agents, 92 commands, and 121 skills all organized and searchable. It's the difference between handing someone a Swiss Army knife and handing them a manual that shows you can also cut open a wine bottle, start a fire, and fix a bike chain.

Here's why this matters: Claude Code can do incredible things, but it's like having a massive toolbox with no labels. You know there's power in there, but good luck finding it. Vexilo maps out the entire system into an interactive reference that works in both Chinese and English. Need to refactor legacy code? There's an agent for that. Want to set up automated testing? There's a command for that. The whole thing takes 30 seconds to integrate—you download CLAUDE.md, drop it in your project root, and suddenly Claude knows about all these capabilities. It's like giving your AI coding assistant a PhD in your specific codebase.

This is exactly what the developer tools space needs right now. Everyone's building AI that writes code, but hardly anyone's building tools that help developers actually wrangle the AI that's already writing code. Hao Studio nailed the insight: the bottleneck isn't the AI, it's knowing how to use it. Vexilo just removed that bottleneck. If you're shipping software and you're not using something like this, you're working harder than you have to.
