Kubernetes Agent
Kubernetes production patterns — manifests, resource sizing, health probes, scaling, secrets, networking, and troubleshooting
Penetration Tester
Authorized penetration tester persona — offensive security specialist for network, web app, cloud, and Active Directory assessments. Requires explicit authorization.
Openai Patterns
Production OpenAI API patterns — model selection, prompt engineering, function calling, streaming, error handling, cost control, and structured outputs
Nextjs Patterns
Production Next.js 14+ patterns — App Router, Server Components, data fetching, caching, performance, and deployment best practices
Code Reviewer
Structured code review across five axes — correctness, security, performance, maintainability, and test coverage. Use when user asks to review code, check a PR, or audit a diff.
Refactor Agent
Safe, systematic code refactoring — extract functions, reduce complexity, eliminate duplication, improve naming. Use when improving code structure without changing behavior.
Test Writer
Write thorough, meaningful tests for any function, module, or API. Use when user asks to add tests, improve coverage, or ensure a piece of code is tested before shipping.
Agent Builder
Build production-ready LLM agents with LangGraph, tool use, memory, streaming, and error handling. Use when designing or implementing an AI agent, multi-agent system, or agentic workflow.
Python Patterns
Python best practices — type hints, async/await, dataclasses, error handling, and performance patterns. Use when writing new Python code, reviewing Python, or modernizing legacy code.
Frontend Developer
Expert frontend developer persona — React/Vue/Angular, performance optimization, Core Web Vitals, accessibility. Builds responsive web apps with pixel-perfect precision.
Api Design
Design REST APIs with consistent naming, error handling, versioning, and pagination. Use when designing a new API, reviewing an existing one, or writing an OpenAPI spec.
Typescript Patterns
Modern TypeScript best practices — strict types, utility types, generics, discriminated unions, and build tooling for production codebases
Cost Tracker
Track, estimate, and optimize LLM API costs across providers. Use when user wants to understand their LLM spending, reduce costs, or compare provider pricing for a given workload.
Yc Job Tracker
Track and filter YC startup job listings for AI/ML engineering roles. Builds a daily-refreshed local database of relevant jobs with scoring and alerts for new postings.
Docker Agent
Write optimized Dockerfiles, docker-compose configs, and debug container issues. Use when containerizing an app, fixing a broken container, or designing a multi-service local environment.
Research Agent
Multi-source deep research with synthesis and inline citations. Use when user asks to research a topic, compare technologies, do competitive analysis, or investigate a subject in depth.
Git Workflow
Git branching, commit conventions, rebase vs merge, conflict resolution, and release tagging. Use when setting up a git workflow, writing commits, resolving conflicts, or preparing a release.
Pr Summarizer
Generate clear, complete pull request descriptions from a diff or commit list. Use when user needs to write a PR description, wants to document a change, or asks for a commit summary.
Doc Generator
Generate accurate, useful documentation for code — README files, API docs, inline docstrings, and changelogs. Use when user needs to document code, write a README, or generate API reference docs.
Sql Agent
Write, optimize, and explain SQL queries. Use when user needs to write a query, debug slow SQL, understand a query plan, or design a schema.
Debug Agent
Systematic root cause analysis for bugs, errors, and unexpected behavior. Use when user reports something broken, an error they can't explain, or unexpected output.
Llm Evaluator
Evaluate LLM outputs systematically using LLM-as-judge, human evaluation frameworks, and regression testing. Use when assessing model quality, comparing models, or preventing quality regression.
React Patterns
React production patterns — hooks, state management, performance optimization, and component design. Use when building React components, reviewing React code, or fixing React performance issues.
System Design
Production system design — scalability patterns, trade-off analysis, database selection, caching strategy, API design, and architecture decisions
Cicd Agent
CI/CD pipeline design and review — GitHub Actions, pipeline best practices, secrets management, deployment strategies, and release automation
Backend Architect
Senior backend architect persona — scalable system design, database architecture, API contracts, microservices, observability, and security-first engineering.
Prompt Optimizer
Analyze and improve LLM prompts for clarity, precision, and output quality. Use when a prompt produces inconsistent results, the model ignores instructions, outputs are too long/short, or quality is below expectations.
Performance Optimizer
Systematic performance profiling and optimization for Python and web backends — measure first, fix second, verify the fix
Rag Evaluator
Evaluate RAG pipeline quality across faithfulness, relevance, and hallucination metrics. Use when user asks to test, benchmark, or improve a RAG system, or when RAG outputs look wrong.
Mle Workflow
Production ML engineering workflow — data contracts, reproducible training, evaluation gates, deployment, and monitoring. Use when building, reviewing, or hardening ML systems beyond notebooks.
Career Ops
Global AI/ML job hunt — USA, Europe, Singapore, Dubai, remote-first startups. Daily fetch, score, and track Senior AI/ML Engineer roles with LangChain/LangGraph/agent stack.
