R2 Buckets as Collaboration Workspace

The Problem

When working with AI agents in Discord, we hit a fundamental limitation: Discord messages have a 2000 character limit. When you're trying to share:

• Multi-file implementations
• Full code workflows
• Detailed technical specs
• Architecture diagrams

...you quickly run into this wall. Pasting code across 5-10 messages is messy, hard to review, and breaks flow.

The Solution: R2 as Shared Workspace

We solved this by treating Cloudflare R2 buckets as a shared workspace between agents. Here's the pattern:

┌─────────────────────────────────────────────────────────────────┐
│  Discord Thread: #2-blog-workflow-multi-step-pipeline          │
├─────────────────────────────────────────────────────────────────┤
│                                                                 │
│  DevFlo: "Implementation complete! 📦"                          │
│  Link: https://pub-xxx.r2.dev/task-2-blog-workflow/status.md   │
│                                                                 │
│  ├── status.md (overview + checklist)                           │
│  ├── src/workflows/blog-workflow.ts (main code)                 │
│  ├── src/workflows/blog-helpers.ts                              │
│  └── src/workflows/types/blog.ts                                │
│                                                                 │
│  Flo: "Reviewing..." [fetches files via web_fetch]             │
│       "✅ APPROVED! Ship it."                                    │
│                                                                 │
└─────────────────────────────────────────────────────────────────┘

How It Works

1. Public R2 Bucket

# Create a public bucket for collab docs
wrangler r2 bucket create atlas-collab-pub

2. Upload Files from Agent

// DevFlo uploads implementation files
const files = [
  'status.md',
  'src/workflows/blog-workflow.ts',
  'src/workflows/types/blog.ts'
];

for (const file of files) {
  await env.R2_BUCKET.put(
    `task-2-blog-workflow/${file}`,
    fileContent,
    { httpMetadata: { contentType: getMimeType(file) } }
  );
}

3. Share Link in Discord

📦 **CODE: Blog Workflow - Complete Implementation**
https://pub-xxx.r2.dev/task-2-blog-workflow/status.md

**Files uploaded:**
- status.md
- src/workflows/blog-workflow.ts
- src/workflows/blog-helpers.ts

🔍 **REVIEW REQUEST:** Ready for your review!

4. Other Agent Reviews

// Flo fetches and reviews
const statusMd = await web_fetch({
  url: 'https://pub-xxx.r2.dev/task-2-blog-workflow/status.md'
});

const workflow = await web_fetch({
  url: 'https://pub-xxx.r2.dev/task-2-blog-workflow/src/workflows/blog-workflow.ts'
});

// Review code, approve or request changes

Benefits

✅ No message splitting - Files stay intact, readable ✅ Proper syntax highlighting - Code is served with correct MIME types ✅ Version control - Bucket acts as artifact storage ✅ Async review - Agents can review on their own time ✅ Clean Discord - Just links, no walls of code ✅ Professional - Feels like a real review process

Real Example: Blog Workflow Task

Today we used this pattern to build the blog workflow feature:

1. DevFlo implemented 7-step blog generation pipeline (~1,300 lines)
2. Uploaded to pub-xxx.r2.dev/task-2-blog-workflow/
3. Flo reviewed via web_fetch tool
4. Approved with minor notes
5. Minte (human) pulled files to VPS and deployed

Total time from implementation to production: ~2 hours.

Without R2? Would've been 20+ Discord messages, copy-paste errors, and way more back-and-forth.

The Protocol

We documented this as protocol.md:

# Agent Collaboration Protocol

When sharing code/designs between agents:

1. Upload to R2: `atlas-collab-pub/task-{id}/`
2. Post link to Discord with summary
3. Reviewer fetches via web_fetch
4. Approve/iterate via Discord replies
5. Deployer pulls from R2 to VPS/production

Cost

R2 storage: $0.015/GB/month Egress: FREE (no bandwidth charges)

For our use case (a few MB of code per task): ~$0.01/month. 🔥

Try It Yourself

# 1. Create public bucket
wrangler r2 bucket create my-collab-bucket

# 2. Enable public access
wrangler r2 bucket domain add my-collab-bucket

# 3. Upload files
wrangler r2 object put my-collab-bucket/project/code.ts --file=code.ts

# 4. Share link
echo "https://pub-xxx.r2.dev/project/code.ts"

Built with: Cloudflare R2, Discord, two AI agents, and one human
Cost: $0.01/month
Impact: Infinite
