## What it does

This skill guides the assistant through bucket snapshots and isolated forks using the `@tigrisdata/storage` TypeScript SDK. Unlike standard object storage systems that track versions object by object, Tigris captures the state of the entire bucket at once.

Forks rely on copy-on-write logic over immutable objects with reverse timestamps. A forked bucket reads directly from the parent snapshot until you modify files. No data is duplicated during creation. Any file deletion or write inside the fork leaves the original bucket untouched.

You must have `@tigrisdata/cli` available in your environment before running operations. The bucket must also have `enableSnapshot: true` configured during initial creation, or snapshot generation will fail.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add tigrisdata/skills --skill tigris-snapshots-forking -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/tigris-snapshots-forking/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/tigris-snapshots-forking/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add tigrisdata/skills --skill tigris-snapshots-forking -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/tigris-snapshots-forking/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add tigrisdata/skills --skill tigris-snapshots-forking -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/tigris-snapshots-forking/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install tigrisdata/skills tigris-snapshots-forking
```

2. **Manually: put the files in place**
- File: `.github/skills/tigris-snapshots-forking/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add tigrisdata/skills --skill tigris-snapshots-forking -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/tigrisdata/skills --path skills/tigris-snapshots-forking
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/tigris-snapshots-forking/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add tigrisdata/skills --skill tigris-snapshots-forking -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/tigrisdata/skills/tree/HEAD/skills/tigris-snapshots-forking/SKILL.md

## When to use it
- spin up developer sandboxes using production bucket data
- take a full bucket snapshot before running database migrations
- provision isolated storage environments for AI agent runs
- recover deleted files using point-in-time snapshot reads

## Example prompts
- Take a snapshot of the `production` bucket named `pre-migration`
- Create an isolated fork from the `agent-seed` bucket snapshot
- Read `config.json` directly from snapshot version `1751631910169675092`

# Tigris Snapshots and Forking

## Prerequisites

**Before doing anything else**, install the Tigris CLI if it's not already available:

```bash
tigris help || npm install -g @tigrisdata/cli
```

If you need to install it, tell the user: "I'm installing the Tigris CLI (`@tigrisdata/cli`) so we can work with Tigris object storage."

## Overview

**Snapshots** capture your entire bucket at a point in time. **Forking** creates instant, isolated copies from snapshots using copy-on-write.

**Core principle:** Snapshots and forks protect your data from deletion. Even if you delete everything in a fork, the source bucket data remains intact.

## Why Snapshots Matter

Object storage serves as the primary data store for many systems. It needs safety features:

- **Point-in-time recovery** - Restore after accidental deletion or corruption
- **Version control** - Tag meaningful states like releases
- **Reproducibility** - Recreate exact environments for debugging or testing
- **Deletion protection** - Forks can be destroyed without affecting source

Traditional object versioning only works per-object. To restore a bucket to a point in time, you must check and restore each object individually. Tigris snapshots capture the entire bucket state instantly.

## Why Forking Matters

Forking creates isolated bucket copies instantly - even for terabytes of data:

- **Developer sandboxes** - Test with real production data safely
- **AI agent environments** - Spin up agents with pre-loaded dependencies
- **Load testing** - Use production data without risk
- **Feature branch testing** - Parallel environments for experiments
- **Training experiments** - Fork datasets to test without affecting source

**How it works:** Tigris uses immutable objects with backwards-ordered timestamps. Forks read from the parent snapshot until new data overwrites. This makes forking essentially free - no data copying required.

## Quick Reference

| Operation       | Function                                | Key Parameters                         |
| --------------- | --------------------------------------- | -------------------------------------- |
| Create snapshot | `createBucketSnapshot(options)`         | name, sourceBucketName                 |
| List snapshots  | `listBucketSnapshots(sourceBucketName)` | sourceBucketName                       |
| Create fork     | `createBucket(name, options)`           | sourceBucketName, sourceBucketSnapshot |

## Create Snapshot

```typescript
import { createBucketSnapshot } from "@tigrisdata/storage";

// Snapshot default bucket
const result = await createBucketSnapshot();
if (result.error) {
  console.error("Error:", result.error);
} else {
````
