uStack

Universal agent workspace compatibility and update engine. Track upstream agent frameworks (like gstack), analyze every change, classify portability, and generate adapted output for your runtime. Use when you want to import, analyze, adapt, or publish updates from upstream agent-native repos across Claude Code, Codex, OpenClaw, Gemini CLI, Cursor, and more.

uStack — One Workspace. Any Agent.

uStack watches frontier agent-native workspaces, analyzes each upstream change, and produces a portable version that works for your agent/runtime.

Commands

Import an upstream framework

bash

node ustack/bin/ustack.js import https://github.com/garrytan/gstack --name gstack

Clones the upstream repo, detects key files (skills, control docs, config, tooling), identifies structure (skill count, host conventions, category), and writes a manifest.

Analyze changes

bash

node ustack/bin/ustack.js analyze gstack

Diffs HEAD against previous snapshot. Classifies impact across 8 areas: skills, install, browser, workflow, safety, tooling, docs, config. Assesses portability: portable / needs-adaptation / host-specific.

Publish update page

bash

node ustack/bin/ustack.js publish gstack

Generates a website-ready markdown page with YAML frontmatter. Includes: summary, impact table, portability breakdown, commit list, usage instructions, and trust notes.

Output lands in .ustack/site/updates/<id>/ — ready for blog/feed integration.

Update (all-in-one)

bash

node ustack/bin/ustack.js update gstack

Combines import → analyze → publish. Cron-friendly — only proceeds with analyze+publish if upstream actually changed.

Doctor

bash

node ustack/bin/ustack.js doctor

Shows configured upstreams, last import/analysis dates, skill counts, host conventions, and flags upstreams with unanalyzed changes pending.

Architecture

text

Upstream repo → uStack IR → Target runtime

No pairwise adapters. One normalized intermediate representation, one renderer per target. Adding a new upstream or target is independent.

Run Artifacts

text

.ustack/
  upstreams/<id>/manifest.json     — upstream metadata + revision tracking
  runs/<id>/<timestamp>/           — analysis.json, analysis.md, publish.md
  site/updates/<id>/<date>.md      — website-ready update pages

• garrytan/gstack — workflow-skill framework (36 skills, 8 agent hosts)
• More upstreams can be added with ustack import <url> --name <id>

Requirements

• Node.js >= 20
