JavaScript style and best practices based on Google's official JavaScript Style Guide. This skill should be used when writing, reviewing, or refactoring JavaScript code to ensure consistent style and prevent common bugs. Triggers on tasks involving JavaScript, ES6, modules, JSDoc, naming conventions, or code formatting.
Comprehensive security audit and vulnerability detection for JavaScript/TypeScript applications following OWASP Top 10. Use when (1) Users say 'audit security', 'check for vulnerabilities', 'security review', 'implement authentication', 'secure this code', (2) Adding authentication, API endpoints, file uploads, or handling user input, (3) Working with secrets, credentials, or sensitive data, (4) Implementing payment features or blockchain integrations, (5) Conducting pre-deployment security checks. Audits for: hardcoded secrets, injection vulnerabilities, XSS/CSRF, broken access control, insecure authentication, rate limiting, dependency vulnerabilities, sensitive data exposure.
Port phone numbers into Telnyx. Check portability, create port orders, upload LOA documents, and track porting status. This skill provides JavaScript SDK examples.
Write JavaScript or Python for the n8n Custom Code Tool (@n8n/n8n-nodes-langchain.toolCode) — the AI-agent-callable tool, NOT the workflow Code node. Use when building a Code Tool attached to an AI Agent, writing code that an LLM will invoke, parsing the `query` input, returning a string result, defining an input schema for structured arguments (specifyInputSchema, jsonSchemaExample, DynamicStructuredTool), or troubleshooting errors like "Wrong output type returned", "No execution data available", "The response property should be a string, but it is an object", "Cannot assign to read only property 'name'", or an AI agent that refuses to call the tool. Covers the critical differences between Code node and Code Tool: return format (string vs `[{json:{...}}]`), unavailability of `$fromAI`/`$input`/`$helpers` in the Code Tool sandbox, naming rules for AI invocation, and when to use `toolWorkflow`/HTTP Request Tool instead.
Write Celigo JavaScript hook scripts -- preSavePage, preMap, postMap, postSubmit, postResponseMap, filter, transform, branching, handleRequest. Use when creating or editing scripts, choosing the right hook point, understanding input/output data shapes, or debugging script behavior.
