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).
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
Stable, minimal, rarely changes. Axioms the rest builds on.

| 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 |
AI development orchestrator — structured discovery, human-in-the-loop, quality gates. Before a single line of code, noskills asks the right questions.
Standalone install:curl -fsSL https://raw.githubusercontent.com/eser/stack/main/etc/scripts/install.sh | sh -s noskills
(or brew/npm/nix — see Install the CLI) In Claude Code:
Add to your project and use via deno task cli noskills spec new "description"
Ensure that Deno 2.9.5 or higher is installed on your system first.
# macOS / Linux — install script
curl -fsSL https://raw.githubusercontent.com/eser/stack/main/etc/scripts/install.sh | sh
# Downloads the eser binary to ~/.local/bin. Inspect the script before running:# https://raw.githubusercontent.com/eser/stack/main/etc/scripts/install.sh# Homebrew
brew install eser/tap/eser
# Nix
nix run github:eser/stack
# Deno (via JSR)
deno run jsr:@eserstack/cli
# npm / npx
npm install -g eser
# or: npx eser <command>Four binaries ship from this repo, all at one version from one pipeline:
| Binary | What it is | Install |
|---|---|---|
eser | the full CLI | curl -fsSL .../install.sh | sh |
noskills | the spec workflow, on its own | ... | sh -s noskills |
laroux | the laroux.js CLI, on its own | ... | sh -s laroux |
noskills-server | the session daemon (Go) | ... | sh -s noskills-server |
The installer is
https://raw.githubusercontent.com/eser/stack/main/etc/scripts/install.sh, and
the product is its argument. On Windows use install.ps1 with -Product.
Homebrew has a formula per binary (brew install eser/tap/noskills), and
eser, noskills and laroux are also on npm.
noskills and laroux are not separate programs — they are the same modules
eser mounts, re-rooted so they can be installed alone. Every one of them
carries the same system tree:
noskills system install # also: uninstall, update, completions,
noskills system doctor # version, doctor, info
noskills version # short aliases: install, update, version, doctorSubmodules deliberately do not: eser noskills version does not exist, because
a submodule is not a program with a version of its own. noskills-server is the
exception in the other direction — being a Go daemon, it has its own command set
(start, doctor, pin, install-service, quickstart) rather than this
one.
