eserstack

eserstack is eser's personal software workshop — a foundation layer, developer
tools, and product incubator, all built on a single philosophy.

This workshop runs on a shared philosophy (PHILOSOPHY.md)
and a common set of directives that apply across all packages, contributors,
and community channels
(@eserstack/directives).

Why eserstack?

Built for developers who:

Think in layers — foundation first, tools on top, products last
Believe in explicit constraints — quality is encoded at the start, not
gated at the end
Want human-in-the-loop AI — tools that think but don't decide
Build to ship — real products, not perpetual side projects

Where to start

Goal	Entry point
AI-assisted project development	noskills → install
Add typed utilities to your project	@eserstack/fp, @eserstack/di → `pnpm add jsr:@eserstack/fp`
Build a web app	laroux → laroux docs
Understand the philosophy	PHILOSOPHY.md → read it
Understand how eserstack operates	@eserstack/directives → ecosystem rules

noskills

AI development orchestrator — structured discovery, human-in-the-loop, quality
gates. Before a single line of code, noskills asks the right questions.

Standalone install: pnpm add jsr:@eserstack/noskills (or curl/npx/brew/nix
— see all options) In Claude Code: Add to your
project and use via deno task cli noskills spec new "description"
