variables: Record<string, string>; // Parsed environment variables
}>
```
### Examples
```typescript
const environments = bruno_list_environments({
collectionPath: "/path/to/collection"

---
## Common Patterns
### Sequential Execution
```typescript
// 1. Discover collections
const collections = bruno_discover_collections({ searchPath: "/workspace" });
// 2. Validate first collection
const validation = bruno_validate_collection({ collectionPath: collections[0] });
if (validation.valid) {
// 3. List requests
const requests = bruno_list_requests({ collectionPath: collections[0] });
// 4. Execute first request
const result = bruno_run_request({
collectionPath: collections[0],
requestName: requests[0].name,
environment: "dev"
});
}
```
### Environment Workflow
```typescript
// 1. List available environments
const envs = bruno_list_environments({ collectionPath: "/path/to/collection" });
// 2. Validate chosen environment
const validation = bruno_validate_environment({
collectionPath: "/path/to/collection",
environmentName: "production"
});
if (validation.valid) {
// 3. Run with validated environment
bruno_run_collection({
collectionPath: "/path/to/collection",
environment: "production"
});
}
```
### Inspection Before Execution
```typescript
// 1. Get request details
const details = bruno_get_request_details({
collectionPath: "/path/to/collection",
requestName: "Delete User"
});
console.log(`Method: ${details.method}`);
console.log(`URL: ${details.url}`);
console.log(`Tests: ${details.tests.length}`);
// 2. Dry run to validate
const dryRun = bruno_run_request({
collectionPath: "/path/to/collection",
requestName: "Delete User",
dryRun: true
});
// 3. Execute if validation passes
if (dryRun.exitCode === 0) {
bruno_run_request({
collectionPath: "/path/to/collection",
requestName: "Delete User",
environment: "dev"
});
}
```

## Error Codes
| Exit Code | Meaning |
|-----------|---------|
| 0 | Success |
| 1 | General error |
| 2 | Invalid parameters |
| 3 | Collection not found |
| 4 | Request not found |
| 5 | Bruno CLI not available |
