Research harness engineer for experiment campaigns: builds evaluation harnesses that are hard to fool, then keeps every reported number honest - null models first, calibration/held-out separation, baseline reproduction before improvement claims, paired error bars, and guards verified by deliberate breakage.

LLM judge for plugin quality assessment. Scores skills on triggering accuracy, orchestration fitness, output quality, and scope calibration using anchored rubrics.

Create, update, or review Azure IaC in Bicep using Azure Verified Modules (AVM).

Analyzes and optimizes content structure including header hierarchy, suggests schema markup, and internal linking opportunities. Creates search-friendly content organization. Use PROACTIVELY for content structuring.

Support development of .NET (OOP) WinForms Designer compatible Apps.

Feature and code implementation with intelligent persona activation and MCP integration

Use when the user wants to analyze retention, cohort behavior, engagement trends, or understand how different user groups perform over time. Triggers on: 'cohort analysis', 'retention analysis', 'user retention', 'cohort retention', 'week 1 retention', 'retention curve'.

Use this agent when you need to analyze slow queries, optimize database performance across multiple systems, or implement indexing strategies to improve query execution.

Expert Kubernetes architect specializing in cloud-native infrastructure, advanced GitOps workflows (ArgoCD/Flux), and enterprise container orchestration. Masters EKS/AKS/GKE/OKE, service mesh (Istio/Linkerd), progressive delivery, multi-tenancy, and platform engineering. Handles security, observability, cost optimization, and developer experience.

The Antigravity Security orchestrator, for use only as the main agent of a session (claude --agent claude-security:claude-security), where it runs a scan end to end and can turn its findings into targeted patch files, each verified by a panel of agents. Never dispatch it as a subagent: it cannot scan from there. When a user asks for Antigravity Security in a conversation, use the claude-security:claude-security skill instead.

Use this agent when you need to audit Active Directory security posture, evaluate privilege escalation risks, review identity delegation patterns, or assess authentication protocol hardening.

Use this agent when you need to build, implement, or enhance automated test frameworks, create test scripts, or integrate testing into CI/CD pipelines.

Use this agent when the user wants to discover, browse, or install Claude Code agents from the awesome-claude-code-subagents repository.

Use this agent when building server-side APIs, microservices, and backend systems that require robust architecture, scalability planning, and production-ready implementation.

Fine-tuning strategist who owns the eval gate and method/model selection. Refuses to plan training without a baselined eval harness. Use PROACTIVELY when a user wants to fine-tune a model, before any training configuration exists.

Agent for Oracle-to-PostgreSQL application migrations. Educates users on migration concepts, pitfalls, and best practices; makes code edits and runs commands directly.

Interactive PRD generator - problem-first, hypothesis-driven product spec with back-and-forth questioning

Identify and fix slow Postgres queries automatically using Neon's branching workflow. Analyzes execution plans, tests optimizations in isolated database branches, and provides clear before/after performance metrics with actionable code fixes.
