Hi HN,

I’ve been working on a simple idea: instead of hard-coding capabilities into Codex-like agents, let them install skills on demand, from a public registry.

The setup is intentionally minimal:

A public skill registry (JSON index + signed artifacts)

A CLI (npx codex-skill install <skill>) for humans

A Model Context Protocol (MCP) server so agents can:

search skills

fetch manifests

verify artifacts

install workflows programmatically

As a concrete example, the first skill is a theming skill for frontend projects (static HTML or Next.js + shadcn/ui). An agent can install the skill, apply a theme, and produce a clean diff in under a minute.

What this enables:

Agents that evolve without redeploying the core model

A neutral, inspectable “app store” for agent skills

Deterministic workflows (install → apply → diff → verify)

Humans and agents using the same install path

This is early and intentionally boring technically. The goal is to see if a shared skill ecosystem for agents actually makes sense in practice.

Happy to hear thoughts, criticism, or similar experiments people have tried.

Hey HN!

As a developer, I got frustrated with the screenshot workflow for documentation: Open DevTools → Set viewport size → Take screenshot → Switch tabs → Download → Open editor → Annotate → Save → Repeat...

Built ZScreenshot - a sidebar extension that keeps everything in one place. Set viewport once, capture instantly, edit in sidebar. No tab switching, no DevTools.

Free: • Custom viewport (consistent screenshot sizes, no sidebar interference) • Full-page capture (scrolling pages) • Tab recording with audio • Privacy-first (all local processing except authentication)

Pro (14-day free trial, no credit card): • Image editor (arrows, shapes, text, blur, emoji - instant annotations) • Collection (merge multiple screenshots for comparisons) • Bulk ZIP download • MP4 export

Everything happens in the sidebar: Capture → Edit → Download → Access history anytime.

Why no "select area before capture"? OS tools (Win+Shift+S, Cmd+Shift+4) already do this perfectly. ZScreenshot focuses on what they can't: viewport control, instant editing, history management. Plus, crop-after-capture gives more flexibility.
