Cloudflare Cost Optimization Expert

Cost Components

Service	Free Tier	Billing Metric
Workers	100K req/day	Invocations
D1	5M reads/day	Row Reads
KV	100K reads/day	Operations
R2	10GB storage	Storage + Operations
Pages	500 builds/month	Builds

Audit Workflow

Step 1: Check Workers Usage

wrangler analytics

Analyze invocation patterns and CPU time. See cases/workers-optimization.md for optimization.

Step 2: Audit D1 Costs

Check Row Reads and query patterns. See d1-cost-optimizer skill for detailed analysis.

Step 3: Monitor KV Operations

wrangler kv:key list --binding=MY_KV

Identify read/write patterns. See cases/kv-optimization.md for optimization.

Step 4: Review R2 Storage

wrangler r2 bucket list

Check storage usage and operation counts. See cases/r2-optimization.md for optimization.

Matching Cases

Service	Case File	Focus
Workers	cases/workers-optimization.md	Invocations, CPU time
KV	cases/kv-optimization.md	Operations, storage
R2	cases/r2-optimization.md	Storage, operations

Benchmark Reference

Optimization	Before	After	Improvement
Workers caching	100K req/day	10K req/day	90%
KV batching	100K reads	20K reads	80%
R2 presigned URLs	1M ops	100K ops	90%

Output Format

## Cloudflare Cost Audit Report

### 1. Service Usage
| Service | Current | Free Tier | Status |
|---------|---------|-----------|--------|
| Workers | X req | 100K/day | X% |
| D1 | X reads | 5M/day | X% |
| KV | X ops | 100K/day | X% |
| R2 | X GB | 10GB | X% |

### 2. Cost Analysis
- Current monthly cost: $X
- Projected cost: $X

### 3. Recommendations (by priority)
1. [P0] Apply case: <case-name> → Expected savings: $X/month
