# AWS S3 Intelligent-Tiering & Storage Lifecycle Policies

Configures AWS S3: Intelligent-Tiering archive access tiers, lifecycle transitions (Standard -> Glacier Flexible -> Deep Archive), noncurrent version expiration, and aborting incomplete multipart uploads.

## When to Invoke
Invoke this skill whenever you need to:
- configure s3 lifecycle rule
- enable s3 intelligent tiering
- abort incomplete multipart uploads s3

## Execution SOP & Rules
1. Define lifecycle JSON with Filter (Prefix/Tags) and Status: Enabled.
2. Add rule: AbortIncompleteMultipartUpload: { DaysAfterInitiation: 7 }.
3. Add Transitions: [{ Days: 30, StorageClass: 'INTELLIGENT_TIERING' }, { Days: 180, StorageClass: 'DEEP_ARCHIVE' }].
4. Apply policy: aws s3api put-bucket-lifecycle-configuration --bucket <bucket> --lifecycle-configuration file://rules.json.

## Verification Checklist
- Run local linting, syntax validation, and type-checks before reporting completion.
- Ensure all created or modified files adhere to workspace boundaries and avoid uncommitted secrets.
- Verify tests or build commands exit cleanly with return code 0.
