# Manage CloudBase Web Storage

Browser storage workflows can fail when buckets, domains, or access rules are incomplete. This skill guides CloudBase Web SDK uploads, downloads, temporary URLs, and environment checks.

## Install

## Capabilities

- Shows when to use CloudBase Web SDK storage methods for browser apps.
- Explains upload, temporary URL, delete, and download flows.
- Distinguishes PG storage buckets from legacy CloudBase storage paths.
- Describes security-domain checks for local and hosted browser origins.
- Provides error-handling guidance for missing buckets and failed uploads.

## Use Cases

- Add Browser Uploads: Implement a Web SDK upload flow that stores files and returns a usable preview URL.
- Diagnose Storage Setup: Check missing buckets, security domains, and upload errors before changing application code.
- Plan PG Storage Access: Configure PG storage bucket usage and RLS expectations for authenticated browser users.

## Prompt Templates

### Upload A File

```
Use CloudBase Web SDK to upload a selected browser file. Include the setup checks I need before testing.
```

### Preview An Uploaded File

```
Build a CloudBase browser upload flow that resolves a temporary preview URL after the upload succeeds.
```

### Fix Upload Failures

```
Diagnose my CloudBase Web SDK upload failure. Check bucket existence, security domains, and the correct API for my storage mode.
```

### Design PG Storage Rules

```
Plan a CloudBase PG storage browser workflow with bucket naming, authenticated uploads, signed URLs, and RLS policy considerations.
```

## Limitations

- It does not replace CloudBase product documentation or console permissions.
- It does not create buckets, domains, or RLS policies by itself.
- It focuses on browser-side storage, not backend batch storage management.
- It assumes the user can access the correct CloudBase environment.

## Best Practices

- Confirm the storage bucket and browser security domain before testing uploads.
- Use temporary URLs instead of constructing public links by hand.
- Reject the parent workflow when an upload fails.

## Anti Patterns

- Do not fabricate a file URL after a failed upload.
- Do not use legacy NoSQL upload methods for PG storage buckets.
- Do not assume a fixed local development port is already trusted.

## Security Audit

- Audited at: 2026-07-09T15:37:30.417\+00:00
- Summary: All static findings were reviewed against SKILL.md context and adjudicated as false positives. The matches are Markdown code spans, documentation URLs, local-origin examples, relative skill references, or setup guidance rather than executable code or malicious intent.
