Cloudflare Manager

Comprehensive Cloudflare service management skill that enables deployment and configuration of Workers, KV Storage, R2 buckets, Pages, DNS records, and routing. Automatically validates API credentials, extracts deployment URLs, and provides actionable error messages.

Initial Setup

Before using this skill for the first time:

1. Install Dependencies

   cd ~/.agents/skills/cloudflare-manager
   bun install
   

2. Configure API Key

   Create a .env file in your project root:

   CLOUDFLARE_API_KEY=your_api_token_here
   CLOUDFLARE_ACCOUNT_ID=your_account_id  # Optional, auto-detected
   

   Getting your API token:

   • Visit https://dash.cloudflare.com/profile/api-tokens
   • Click "Create Token"
   • Use "Edit Cloudflare Workers" template (or create custom token)
   • Required permissions:
     • Account > Workers Scripts > Edit
     • Account > Workers KV Storage > Edit
     • Account > Workers R2 Storage > Edit
     • Account > Cloudflare Pages > Edit
     • Zone > DNS > Edit (if using custom domains)

3. Validate Credentials

   Run validation to verify your API key and check permissions:

   cd ~/.agents/skills/cloudflare-manager
   bun scripts/validate-api-key.ts
   

   Expected output:

   ✅ API key is valid!
   ℹ️  Token Status: active
   ℹ️  Account: Your Account Name (abc123...)
   
   🔑 Granted Permissions:
     ✅ Workers Scripts: Edit
     ✅ Workers KV Storage: Edit
     ✅ Workers R2 Storage: Edit
   

   Troubleshooting validation:

   • If validation fails with 401/403: Check your API token is correct in .env
   • If validation fails with network error: Check internet connection
   • Use --no-cache flag to force fresh validation: bun scripts/validate-api-key.ts --no-cache

Current API Permissions

Run bun scripts/validate-api-key.ts to populate this section with your current permissions.

Quick Start Guide

Deploy a Worker Container

To deploy a new worker container sandbox:

# Using the skill
bun scripts/workers.ts deploy worker-name ./worker-script.js

What happens:

• Creates new worker container
• Deploys JavaScript/TypeScript code
• Automatically extracts and returns Cloudflare-generated URL (e.g., https://worker-name.username.workers.dev)
• Returns worker ID and configuration

Example conversation:

User: "Set up and deploy a new cloudflare worker container sandbox named 'api-handler' and return the URL"
Agent: [Deploys worker using bun scripts/workers.ts deploy api-handler ./worker.js]
       Returns URL: https://api-handler.username.workers.dev

Exit codes:

• 0: Success - worker deployed and URL returned
• 1: Failure - check error message for details

Performance: Deployment typically completes in 2-5 seconds

Create and Use KV Storage

To create a KV namespace and store data:

# Create namespace
bun scripts/kv-storage.ts create-namespace user-sessions
# Returns: Namespace ID (e.g., abc123def456)
# Save this ID for binding to workers

# Write key-value pair
bun scripts/kv-storage.ts write <namespace-id> "session:user123" '{"userId":"123","token":"abc"}'

# Read value
bun scripts/kv-storage.ts read <namespace-id> "session:user123"
# Returns: {"userId":"123","token":"abc"}

# List all keys (useful for debugging)
bun scripts/kv-storage.ts list-keys <namespace-id>

# Delete a key
bun scripts/kv-storage.ts delete <namespace-id> "session:user123"

Important: KV storage uses eventual consistency. Writes may take up to 60 seconds to propagate globally. For immediate reads, use the same edge location where you wrote the data.

Create R2 Bucket and Upload Files

To create an R2 bucket and manage objects:

# Create bucket
bun scripts/r2-storage.ts create-bucket media-assets

# Upload file
bun scripts/r2-storage.ts upload media-assets ./images/logo.png logo.png

# List objects
bun scripts/r2-storage.ts list-objects media-assets

# Download object
bun scripts/r2-storage.ts download media-assets logo.png ./downloaded-logo.png

Deploy to Cloudflare Pages

To deploy a static site or application to Pages:

# Create Pages project (or get existing project info)
bun scripts/pages.ts deploy my-app ./dist
# Returns: https://my-app.pages.dev

# Set environment variable
bun scripts/pages.ts set-env my-app API_URL https://api.example.com

# Set environment variable for specific environment
bun scripts/pages.ts set-env my-app DEBUG true --env preview

# Get deployment URL
bun scripts/pages.ts get-url my-app

Auto-extracted URLs: The Pages script automatically extracts and returns the Cloudflare-generated URL (e.g., https://my-app.pages.dev) from the deployment response.

Note: The API creates the project structure, but for actual file uploads, you'll need Wrangler CLI:

npx wrangler pages deploy ./dist --project-name=my-app

Why this works: The skill creates/verifies the Pages project and returns the URL. For the initial deployment with files, Wrangler handles the complex multipart upload process.

Configure DNS and Routes

To create DNS records and configure worker routes:

# Create DNS A record
bun scripts/dns-routes.ts create-dns example.com A api 192.168.1.1

# Route pattern to worker
bun scripts/dns-routes.ts create-route example.com "*.example.com/api/*" api-handler

Common Workflows

Multi-Service Setup

To set up a complete application with worker, KV storage, and R2 bucket:

1. Create KV namespace for caching

   bun scripts/kv-storage.ts create-namespace app-cache
   

2. Create R2 bucket for media

   bun scripts/r2-storage.ts create-bucket app-media
   

3. Deploy worker with bindings

   bun scripts/workers.ts deploy app-worker ./worker.js --kv-binding app-cache --r2-binding app-media
   

4. Configure route

   bun scripts/dns-routes.ts create-route example.com "example.com/*" app-worker
   

Update Worker Configuration

To update an existing worker's code or bindings:

# Update worker code
bun scripts/workers.ts update worker-name ./new-worker-script.js

# Get worker details
bun scripts/workers.ts get worker-name

# List all workers
bun scripts/workers.ts list

Bulk KV Operations

To perform bulk operations on KV storage:

# Bulk write from JSON file
bun scripts/kv-storage.ts bulk-write namespace-name ./data.json

# Delete multiple keys
bun scripts/kv-storage.ts bulk-delete namespace-name key1 key2 key3

Error Handling

Missing API Key

If .env file is missing or CLOUDFLARE_API_KEY is not set:

Error: CLOUDFLARE_API_KEY not found in environment

Solution: Create .env file in project root:
  echo "CLOUDFLARE_API_KEY=your_token_here" > .env

Invalid Permissions

If API token lacks required permissions:

Error: Insufficient permissions for Workers deployment

Required: Workers Scripts: Edit
Current: Workers Scripts: Read

Solution: Update token permissions at:
  https://dash.cloudflare.com/profile/api-tokens

API Rate Limiting

If too many requests are made:

Error: Rate limit exceeded (429)

Solution: Retry automatically with exponential backoff (3 attempts)

Network Issues

If API is unreachable:

Error: Failed to connect to Cloudflare API

Solution: Check internet connection and retry

Best Practices

Security:

• Never commit .env files - always add to .gitignore
• Use token-based authentication (not API keys)
• Rotate tokens periodically (every 90 days recommended)
• Use least-privilege principle: only grant required permissions
• Store secrets via Wrangler CLI: wrangler secret put SECRET_NAME

Performance:

• Deploy workers to minimize latency (they run at Cloudflare edge)
• Use KV storage for frequently-read data (not frequently-written)
• Use R2 for large files (KV has 25MB limit per key)
• Enable caching with appropriate TTLs
• Keep worker scripts under 1MB for faster cold starts

Development Workflow:

• Test locally first: wrangler dev for local testing
• Use staging environment before production
• Validate credentials after token updates: bun scripts/validate-api-key.ts
• Monitor worker logs: wrangler tail worker-name
• Version your workers: use names like api-v1, api-v2

Naming Conventions:

• Workers: Use descriptive names (e.g., user-auth-worker not worker1)
• KV namespaces: Include purpose (e.g., app-sessions, api-cache)
• R2 buckets: Use lowercase with hyphens (e.g., media-assets-prod)
• Be consistent across your infrastructure

Resource Management:

• Delete unused workers, namespaces, and buckets
• Monitor usage in Cloudflare dashboard
• Free tier limits: 100,000 requests/day for Workers
• Set up billing alerts to avoid surprises

Advanced Usage

For advanced scenarios including:

• Complex routing configurations
• Multi-region deployments
• Custom domain setup
• Worker-to-worker communication
• Durable Objects integration
• Bulk operations and migrations

See examples.md for comprehensive examples and patterns.

Troubleshooting

Common Issues and Solutions

Issue: "Worker deployment failed with unknown error"

Symptoms: Deployment command exits with error code 1, no specific error message

Solutions:

1. Check script syntax: node --check ./worker.js
2. Verify file exists: ls -lh ./worker.js
3. Re-validate API key: bun scripts/validate-api-key.ts --no-cache
4. Check worker name is valid (alphanumeric, hyphens, underscores only)

---

Issue: "KV namespace not found"

Symptoms: Error when trying to read/write to namespace

Solutions:

1. List all namespaces: bun scripts/kv-storage.ts list-namespaces
2. Verify you're using namespace ID (not name) in commands
3. Check namespace wasn't deleted
4. Ensure API token has KV Storage permissions

---

Issue: "R2 bucket already exists" or "Bucket name taken"

Symptoms: Cannot create bucket with chosen name

Solutions:

1. Bucket names must be globally unique across all Cloudflare accounts
2. Try a more specific name: my-app-media-2024 instead of media
3. Use existing bucket: bun scripts/r2-storage.ts list-buckets
4. Names must be 3-63 characters, lowercase letters/numbers/hyphens only

---

Issue: "Pages deployment timeout" or "Deployment pending"

Symptoms: Deployment doesn't complete, stays in pending state

Solutions:

1. Check deployment status: bun scripts/pages.ts list-deployments project-name
2. View in dashboard: https://dash.cloudflare.com/pages
3. Large deployments (>1000 files) may take 5-10 minutes
4. Cancel and retry if stuck: Delete project and recreate

---

Issue: "DNS record creation failed"

Symptoms: Cannot create DNS records or routes

Solutions:

1. Verify zone exists: bun scripts/dns-routes.ts list-zones
2. Ensure domain is added to Cloudflare and active
3. Check nameservers point to Cloudflare: dig NS yourdomain.com
4. Verify API token has Zone > DNS > Edit permission

---

Issue: "API rate limit exceeded (429)"

Symptoms: Commands fail with "Too many requests"

Solutions:

1. Scripts automatically retry with exponential backoff
2. Wait 1-2 minutes before retrying manually
3. Reduce concurrent operations
4. Rate limits: 1200 requests per 5 minutes

---

Issue: "CLOUDFLARE_API_KEY not found in environment"

Symptoms: Commands fail immediately with environment error

Solutions:

1. Create .env file in project root (not skill directory)
2. Verify file content: cat .env | grep CLOUDFLARE_API_KEY
3. Ensure no extra spaces: CLOUDFLARE_API_KEY=token (no spaces around =)
4. Run commands from project root where .env exists

Quick Fix:

cd /path/to/your/project
echo "CLOUDFLARE_API_KEY=your_token_here" > .env
bun scripts/validate-api-key.ts

Security Notes

• API keys are never logged or displayed in output
• All API requests use HTTPS
• User inputs are validated before API calls
• Destructive operations (delete) require confirmation
• Permissions are cached for 24 hours to minimize token exposure
