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.

Best use case

ustack is best used when you need a repeatable AI agent workflow instead of a one-off prompt.

Teams using ustack should expect a more consistent output, faster repeated execution, less prompt rewriting.

When to use this skill

You want a reusable workflow that can be run more than once with consistent structure.

When not to use this skill

You only need a quick one-off answer and do not need a reusable workflow.
You cannot install or maintain the underlying files, dependencies, or repository context.

# 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

```
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

```
.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
```

## Supported Upstreams

- `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
- Git

Workflow & Productivity

Meeting Prep

3891

from openclaw/skills

Never walk into a meeting unprepared again. Your agent researches all attendees before calendar events—pulling LinkedIn profiles, recent company news, mutual connections, and conversation starters. Generates a briefing doc with talking points, icebreakers, and context so you show up informed and confident. Triggered automatically before meetings or on-demand. Configure research depth, advance timing, and output format. Walking into meetings blind is amateur hour—missed connections, generic small talk, zero leverage. Use when setting up meeting intelligence, researching specific attendees, generating pre-meeting briefs, or automating your prep workflow.
