# Gamma Upgrade & Migration

## Current State

!`npm list 2>/dev/null | head -20`
!`pip freeze 2>/dev/null | head -20`

## Overview

Guide for upgrading Gamma SDK versions and migrating between API versions safely.

## Prerequisites

- Existing Gamma integration
- Version control (git)
- Test environment available

## Instructions

### Step 1: Check Current Version

```bash
set -euo pipefail
# Node.js
npm list @gamma/sdk

# Python
pip show gamma-sdk

# Check for available updates
npm outdated @gamma/sdk
```

### Step 2: Review Changelog

```bash
set -euo pipefail
# View changelog
npm info @gamma/sdk changelog

# Or visit
# https://gamma.app/docs/changelog
```

### Step 3: Upgrade SDK

```bash
set -euo pipefail
# Create upgrade branch
git checkout -b feat/gamma-sdk-upgrade

# Node.js - upgrade to latest
npm install @gamma/sdk@latest

# Python - upgrade to latest
pip install --upgrade gamma-sdk

# Or specific version
npm install @gamma/[email protected]
```

### Step 4: Handle Breaking Changes

**Common Migration Patterns:**

```typescript
// v1.x -> v2.x: Client initialization change
// Before (v1)
import Gamma from '@gamma/sdk';
const gamma = new Gamma(apiKey);

// After (v2)
import { GammaClient } from '@gamma/sdk';
const gamma = new GammaClient({ apiKey });
```

```typescript
// v1.x -> v2.x: Response format change
// Before (v1)
const result = await gamma.createPresentation({ title: 'Test' });
console.log(result.id);

// After (v2)
const result = await gamma.presentations.create({ title: 'Test' });
console.log(result.data.id);
```

```typescript
// v1.x -> v2.x: Error handling change
// Before (v1)
try {
  await gamma.create({ ... });
} catch (e) {
  if (e.code === 'RATE_LIMIT') { ... }
}

// After (v2)
import { RateLimitError } from '@gamma/sdk';
try {
  await gamma.presentations.create({ ... });
} catch (e) {
  if (e instanceof RateLimitError) { ... }
}
```

### Step 5: Update Type Definitions

```typescript
// Check for type changes
// tsconfig.json - ensure strict mode catches issues
{
  "compilerOptions": {
    "strict": true,
    "noImplicitAny": true
  }
}

// Run type check
npx tsc --noEmit
```

### Step 6: Test Thoroughly

```bash
set -euo pipefail
# Run unit tests
npm test

# Run integration tests
npm run test:integration

# Manual smoke test
node -e "
const { GammaClient } = require('@gamma/sdk');
const g = new GammaClient({ apiKey: process.env.GAMMA_API_KEY });
g.ping().then(() => console.log('OK')).catch(console.error);
"
```

### Step 7: Deprecation Handling

```typescript
// Enable deprecation warnings
const gamma = new GammaClient({
  apiKey: process.env.GAMMA_API_KEY,
  showDeprecationWarnings: true,
});

// Migrate deprecated methods
// Deprecated
await gamma.getPresentations();

// New
await gamma.presentations.list();
```

## Migration Checklist

- [ ] Current version documented
- [ ] Changelog reviewed
- [ ] Breaking changes identified
- [ ] Upgrade branch created
- [ ] SDK upgraded
- [ ] Type errors fixed
- [ ] Deprecation warnings addressed
- [ ] Unit tests passing
- [ ] Integration tests passing
- [ ] Staging deployment verified
- [ ] Production deployment planned

## Rollback Procedure

```bash
set -euo pipefail
# If issues occur after upgrade
git checkout main
npm install  # Restores previous version from lock file

# Or explicitly downgrade
npm install @gamma/[email protected]
```

jfrog

Included

Interact with the JFrog Platform via the JFrog CLI and REST/GraphQL APIs. Use this skill when the user wants to manage Artifactory repositories, upload or download artifacts, manage builds, configure permissions, manage users and groups, work with access tokens, configure JFrog CLI servers, search artifacts, manage properties, set up replication, manage JFrog Projects, run security audits or scans, look up CVE details, query exposures scan results from JFrog Advanced Security, manage release bundles and lifecycle operations, aggregate or export platform data, or perform any JFrog Platform administration task. Also use when the user mentions jf, jfrog, artifactory, xray, distribution, evidence, apptrust, onemodel, graphql, workers, mission control, curation, advanced security, exposures, or any JFrog product name.

cupynumeric-migration-readiness

Included

Pre-migration readiness assessor for porting NumPy to cuPyNumeric. Use BEFORE substantial porting work begins when the user asks whether code will scale on GPU, whether they should migrate to cuPyNumeric, which NumPy patterns transfer cleanly, what must be refactored before porting, or mentions pre-port assessment, scaling analysis, or refactor planning. Inspect the user's source code, look up NumPy usage, cross-reference the cuPyNumeric API support manifest, and distinguish distributed-scaling-friendly patterns from blockers such as unsupported APIs, scalar synchronization, host round-trips, Python/object-heavy control flow, shape/data-dependent branching, and in-place mutation hazards. Produce a verdict of READY, LIGHT REFACTOR, SIGNIFICANT REFACTOR, or NOT RECOMMENDED, with concrete refactor pointers.

alibabacloud-data-agent-skill

Included

Invoke Alibaba Cloud Apsara Data Agent for Analytics via CLI to perform natural language-driven data analysis on enterprise databases. Data Agent for Analytics is an intelligent data analysis agent developed by Alibaba Cloud Database team for enterprise users. It automatically completes requirement analysis, data understanding, analysis insights, and report generation based on natural language descriptions. This tool supports: discovering data resources (instances/databases/tables) managed in DMS, initiating query or deep analysis sessions, real-time progress tracking, and retrieving analysis conclusions and generated reports. Use this Skill when users need to query databases, analyze data trends, generate data reports, ask questions in natural language, or mention "Data Agent", "data analysis", "database query", "SQL analysis", "data insights".

Backend & APIsscripts

token-optimizer

Included

Reduce OpenClaw token usage and API costs through smart model routing, heartbeat optimization, budget tracking, and native 2026.2.15 features (session pruning, bootstrap size limits, cache TTL alignment). Use when token costs are high, API rate limits are being hit, or hosting multiple agents at scale. The 4 executable scripts (context_optimizer, model_router, heartbeat_optimizer, token_tracker) are local-only — no network requests, no subprocess calls, no system modifications. Reference files (PROVIDERS.md, config-patches.json) document optional multi-provider strategies that require external API keys and network access if you choose to use them. See SECURITY.md for full breakdown.
