  Implement Windsurf reliability patterns including circuit breakers, idempotency, and graceful degradation.
  Use when building fault-tolerant Windsurf integrations, implementing retry strategies,
  or adding resilience to production Windsurf services.
  Trigger with phrases like "windsurf reliability", "windsurf circuit breaker",
  "windsurf idempotent", "windsurf resilience", "windsurf fallback", "windsurf bulkhead".

# Windsurf Reliability Patterns

## Overview
Reliability patterns for Windsurf AI IDE workflows. Windsurf's Cascade agent can modify multiple files simultaneously, making reliable workflows dependent on proper checkpointing, review, and rollback strategies.

## Prerequisites
- Windsurf installed with Cascade enabled
- Git repository for version control
- Understanding of Cascade's multi-file editing model

## Instructions

### Step 1: Commit Before Cascade Sessions

Always create a clean git checkpoint before asking Cascade to make changes.

```bash
# Before starting a Cascade session
git add -A && git commit -m "checkpoint: before cascade refactor"

# Now ask Cascade to make changes
# If results are bad:
git diff               # review what changed
git checkout -- .      # revert everything
# Or keep good changes:
git add specific-file.ts && git commit -m "cascade: extracted service layer"
```

### Step 2: Scope Cascade Tasks Narrowly

Large tasks cause Cascade to make sweeping changes that are hard to review.

```
# BAD: too broad
"Refactor the authentication system"
# Cascade may modify 30+ files

# GOOD: incremental, reviewable steps
Step 1: "Extract the JWT validation logic from src/middleware/auth.ts
         into a new src/services/jwt.ts module"
Step 2: "Update src/middleware/auth.ts to import from src/services/jwt.ts"
Step 3: "Add unit tests for src/services/jwt.ts"
```

### Step 3: Validate After Each Cascade Edit

Run tests and type checks after every Cascade modification.

```bash
set -euo pipefail
# After accepting Cascade changes
npm run typecheck     # catch type errors from refactoring
npm test              # verify existing behavior preserved
npm run lint          # check code style

# If any fail, ask Cascade to fix:
# "The typecheck failed with: [paste error]. Fix the type error in src/services/jwt.ts"
```

### Step 4: Use .windsurfignore for Workspace Performance

Large workspaces slow down Cascade's context building. Exclude build artifacts.

```gitignore
# .windsurfignore
node_modules/
dist/
build/
.next/
coverage/
*.min.js
*.map
__pycache__/
.venv/
```

## Error Handling
| Issue | Cause | Solution |
|-------|-------|----------|
| Cascade broke the build | Accepted changes without testing | Git revert, run tests after each edit |
| Cascade modified wrong files | Ambiguous instructions | Specify exact file paths in prompt |
| Slow Cascade responses | Large workspace indexed | Add `.windsurfignore` |
| Lost good changes | Reverted too broadly | Commit incrementally, use `git stash` |

## Examples

### Safe Cascade Workflow
```bash
set -euo pipefail
git stash                          # save WIP
git checkout -b cascade/refactor   # new branch
# Ask Cascade to make changes
npm test && git add -A && git commit -m "cascade: refactored auth"
# If bad: git checkout main && git branch -D cascade/refactor
```
