Implement Windsurf rate limiting, backoff, and idempotency patterns.
Use when handling rate limit errors, implementing retry logic,
or optimizing API request throughput for Windsurf.
Trigger with phrases like "windsurf rate limit", "windsurf throttling",
"windsurf 429", "windsurf retry", "windsurf backoff".
Windsurf uses a credit-based system for AI features. Each prompt to Cascade consumes credits, with different models costing different amounts. Understanding the credit system prevents mid-session interruptions and optimizes your AI budget.

Step 2: Credit Cost per Model
Different models consume different credit amounts per prompt:
1. Use SWE-1 Lite for simple tasks (free, unlimited):
- Quick questions about syntax
- Simple completions
- Code explanations
2. Use premium models for complex tasks:
- Multi-file refactoring
- Architecture decisions
- Debugging complex issues
3. Write better prompts to reduce back-and-forth:
- Include file paths, constraints, and expected output
- Reference files with @ mentions instead of describing them
- One well-structured prompt > five vague ones
4. Use Workflows for repetitive tasks:
- Workflows consume credits but eliminate wasted retry prompts
- A 5-step workflow costs less than 5 separate conversations
5. Leverage free features:
- Supercomplete (Tab) is unlimited on all plans
- Command mode (Cmd+I) is unlimited on Pro
- Only Cascade Write/Chat consumes credits
Step 5: Handle Credit Exhaustion
When credits run out mid-session:
1. Switch to SWE-1 Lite (unlimited) for basic tasks
2. Use Supercomplete (Tab) for inline coding -- always free
3. Buy additional credits: windsurf.com/account > Buy Credits
4. Wait for monthly reset (credits renew on billing date)
5. Upgrade plan if consistently running out
Step 6: Team Credit Management (Teams/Enterprise)
# Admin Dashboard > Analytics > Credit Usage
team_monitoring:
total_credits: 5000 # 10 users x 500
consumed_this_month: 3200
top_consumers:
- dev_a: 800 credits (power user)
- dev_b: 600 credits (heavy Cascade use)
- dev_c: 50 credits (underutilizing)
actions:
- Offer training to dev_c (low usage = not getting value)
- Review dev_a's usage (is it productive or wasteful?)
- Consider upgrading if team consistently hits limit

Cost-Effective Prompt Strategy
Instead of:
1. "What does this function do?" (1 credit)
2. "Can you add error handling?" (1 credit)
3. "Also add tests" (1 credit)
Total: 3 credits
Do this:
1. "Explain this function, add error handling, and write unit tests
for both success and error paths" (1 credit)
Total: 1 credit
