# Gamma Security Basics

## Overview

Security best practices for Gamma API integration to protect credentials and data.

## Prerequisites

- Active Gamma integration
- Environment variable support
- Understanding of secret management

## Instructions

### Step 1: Secure API Key Storage

```typescript
// NEVER do this
const gamma = new GammaClient({
  apiKey: 'gamma_live_abc123...', // Hardcoded - BAD!
});

// DO this instead
const gamma = new GammaClient({
  apiKey: process.env.GAMMA_API_KEY,
});
```

**Environment Setup:**

```bash
# .env (add to .gitignore!)
GAMMA_API_KEY=gamma_live_abc123...

# Load in application
import 'dotenv/config';
```

### Step 2: Key Rotation Strategy

```typescript
// Support multiple keys for rotation
const gamma = new GammaClient({
  apiKey: process.env.GAMMA_API_KEY_PRIMARY
    || process.env.GAMMA_API_KEY_SECONDARY,
});

// Rotation script
async function rotateApiKey() {
  // 1. Generate new key in Gamma dashboard
  // 2. Update GAMMA_API_KEY_SECONDARY
  // 3. Deploy and verify
  // 4. Swap PRIMARY and SECONDARY
  // 5. Revoke old key
}
```

### Step 3: Request Signing (if supported)

```typescript
import crypto from 'crypto';

function signRequest(payload: object, secret: string): string {
  const timestamp = Date.now().toString();
  const message = timestamp + JSON.stringify(payload);

  return crypto
    .createHmac('sha256', secret)
    .update(message)
    .digest('hex');
}

// Usage with webhook verification
function verifyWebhook(body: string, signature: string, secret: string): boolean {
  const expected = crypto
    .createHmac('sha256', secret)
    .update(body)
    .digest('hex');

  return crypto.timingSafeEqual(
    Buffer.from(signature),
    Buffer.from(expected)
  );
}
```

### Step 4: Access Control Patterns

```typescript
// Scoped API keys (if supported)
const readOnlyGamma = new GammaClient({
  apiKey: process.env.GAMMA_API_KEY_READONLY,
  scopes: ['presentations:read', 'exports:read'],
});

const fullAccessGamma = new GammaClient({
  apiKey: process.env.GAMMA_API_KEY_FULL,
});

// Permission check before operations
async function createPresentation(user: User, data: object) {
  if (!user.permissions.includes('gamma:create')) {
    throw new Error('Insufficient permissions');
  }
  return fullAccessGamma.presentations.create(data);
}
```

### Step 5: Audit Logging

```typescript
import { GammaClient } from '@gamma/sdk';

function createAuditedClient(userId: string) {
  return new GammaClient({
    apiKey: process.env.GAMMA_API_KEY,
    interceptors: {
      request: (config) => {
        console.log(JSON.stringify({
          timestamp: new Date().toISOString(),
          userId,
          action: `${config.method} ${config.path}`,
          type: 'gamma_api_request',
        }));
        return config;
      },
    },
  });
}
```

## Security Checklist

- [ ] API keys stored in environment variables
- [ ] .env files in .gitignore
- [ ] No keys in source code or logs
- [ ] Key rotation procedure documented
- [ ] Minimal permission scopes used
- [ ] Audit logging enabled
- [ ] Webhook signatures verified
- [ ] HTTPS enforced for all calls

## Error Handling

| Security Issue | Detection | Remediation |
|----------------|-----------|-------------|
| Exposed key | GitHub scanning | Rotate immediately |
| Key in logs | Log audit | Filter sensitive data |
| Unauthorized access | Audit logs | Revoke and investigate |
| Weak permissions | Access review | Apply least privilege |

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".

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.
