Django, Flask, FastAPI integration patterns for Celery. Use when integrating Celery with Django, Flask, or FastAPI, setting up framework-specific configurations, handling application contexts, managing database transactions with tasks, configuring async workers, or when user mentions Django Celery, Flask Celery, FastAPI background tasks, framework integration, or web framework task queues.

Verify external libraries, APIs, and frameworks against current documentation before writing code. Use when about to implement features using external dependencies, when writing import statements for third-party libraries, when unsure if a pattern or method is current, or when the user mentions grounding or verification.

This skill provides comprehensive knowledge for working with the Anthropic Messages API (Claude API). It should be used when integrating Claude models into applications, implementing streaming responses, enabling prompt caching for cost savings, adding tool use (function calling), processing images with vision capabilities, or using extended thinking mode.Use when building chatbots, AI assistants, content generation tools, or any application requiring Claude's language understanding. Covers both server-side implementations (Node.js, Cloudflare Workers, Next.js) and direct API access.Keywords: claude api, anthropic api, messages api, @anthropic-ai/sdk, claude streaming, prompt caching, tool use, vision, extended thinking, claude 3.5 sonnet, claude 3.7 sonnet, claude sonnet 4, function calling, SSE, rate limits, 429 errors

Token-efficient codebase navigation through intelligent symbol loading and querying. Use this skill when implementing new features (find existing patterns), exploring codebase structure, searching for components/functions/types, or understanding architectural layers. Reduces token usage by 60-95% compared to loading full files. Layer split enables 50-80% additional backend efficiency.

Deploys public-facing apps that handle their own authentication (like Jellyfin, game servers) without Authelia forward auth

Searches the NIST NVD database for CVE vulnerabilities using API 2.0. Returns CVE details, CVSS scores, affected software, and references. Use when user asks about "CVE", "vulnerability database", "NIST", "NVD", "security advisory", "CVE-2024", "CVE-2023", "脆弱性", "セキュリティアドバイザリ", or wants to find known vulnerabilities for specific software.
