Alien-agen-skills-for-Engineering

A comprehensive collection of Agent Skills for software engineering excellence. Use when designing systems, reviewing code, debugging failures, designing APIs, building test strategies, optimizing performance, hardening security, or responding to incidents. Activate for any senior engineering task.

Use when the user asks to "design an API", "review an API", "choose between REST and GraphQL", "version an API", "design a webhook", or discusses API contracts, backwards compatibility, or client-server interfaces. Provides senior engineering guidance for API design decisions.

Use when the user asks to "review this code", "give me feedback on a PR", "what should I look for in code review", "how do I review a pull request", or wants to improve their code review process. Provides a structured, senior-engineer-level code review framework.

Use when the user says "I have a bug", "this isn't working", "help me debug", "I can't reproduce this", "this works locally but not in production", or needs to trace a failure to its root cause. Provides systematic debugging methodology for software engineers.

Use when the user says "we have an incident", "production is down", "users are reporting errors", "our error rate spiked", "help me write a postmortem", or needs to structure an on-call response. Provides a systematic incident response framework for software engineers and on-call engineers.

Use when the user says "this is too slow", "how do I optimize this", "help me profile this", "our p99 is too high", "we're hitting database limits", or discusses latency, throughput, memory usage, or CPU profiling. Provides systematic performance engineering methodology.

Use when the user asks "is this secure", "how do I prevent SQL injection", "how should I store passwords", "do a threat model", "review this for security issues", "how do I handle authentication", or discusses OWASP, encryption, secrets management, or authorization. Provides security engineering guidance for software engineers.

Use when the user asks to "design a system", "evaluate architecture", "scale a service", "choose between databases", "design for high availability", "review a system design", or discusses distributed systems, microservices, data modeling, or architectural trade-offs. Provides senior engineering guidance for system architecture decisions.

Use when the user asks "how should I test this", "what tests should I write", "is this enough test coverage", "how do I test this without mocking everything", "TDD vs writing tests after", or discusses unit vs integration vs E2E tests. Provides senior engineering guidance on building effective test suites.

Use when the user asks to [action] or says [trigger phrases]. Describe what the skill does and when to activate it. Include enough trigger phrases that the agent can recognize the context automatically.
