What this skill does


# Security Scanner Skill

## Instructions

1. Scan code for security vulnerabilities
2. Check for SQL injection risks
3. Check for XSS vulnerabilities
4. Look for hardcoded secrets/credentials
5. Verify authentication/authorization security
6. Check input validation and sanitization
7. Review dependency security
8. Return structured security reports with:
   - File path and line numbers
   - Vulnerability type and severity
   - Current vulnerable code
   - Suggested secure fix
   - Reason and impact
   - Priority (Must-Fix for critical, Should-Fix for high)

## Examples

**Input:** Hardcoded API key in source code
**Output:**
```markdown
### SEC-001
- **File**: `config.js`
- **Lines**: 12
- **Priority**: Must-Fix
- **Issue**: Hardcoded API key exposed in source code
- **Current Code**:
  ```javascript
  const API_KEY = "sk_live_1234567890abcdef";
  ```
- **Suggested Fix**:
  ```javascript
  const API_KEY = process.env.API_KEY;
  if (!API_KEY) {
      throw new Error("API_KEY environment variable not set");
  }
  ```
- **Reason**: Hardcoded secrets can be exposed in version control and compromise security
```

## Security Issues to Detect

- **SQL Injection**: Unparameterized database queries
- **XSS Vulnerabilities**: Unsanitized user input in HTML
- **Hardcoded Secrets**: API keys, passwords, tokens in code
- **Insecure Authentication**: Weak password requirements, missing 2FA
- **Missing Input Validation**: Unvalidated user input
- **Insecure Dependencies**: Outdated packages with known vulnerabilities
- **CSRF Vulnerabilities**: Missing CSRF tokens
- **Insecure File Uploads**: Unvalidated file types/sizes
- **Path Traversal**: Unvalidated file paths
- **Insecure Random**: Weak random number generation
- **Information Disclosure**: Error messages exposing sensitive data
- **Missing HTTPS**: Insecure communication protocols

## Priority Guidelines

- **Must-Fix**: Critical vulnerabilities (SQL injection, XSS, exposed secrets)
- **Should-Fix**: High-risk vulnerabilities (missing validation, insecure auth)
- **Nice-to-Have**: Medium-risk issues (dependency updates, minor improvements)

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.
