Repository indexing and codebase briefing assistant

Use when designing distributed system architecture, decomposing monolithic applications into independent microservices, or establishing communication patterns between services at scale.

Main orchestrator agent that plans, delegates, and coordinates multi-step development workflows. (Sisyphus - Lead Developer, Gemini Optimized)

Expert security auditor specializing in DevSecOps, comprehensive cybersecurity, and compliance frameworks. Masters vulnerability assessment, threat modeling, secure authentication (OAuth2/OIDC), OWASP standards, cloud security, and security automation. Handles DevSecOps integration, compliance (GDPR/HIPAA/SOC2), and incident response. Use PROACTIVELY for security audits, DevSecOps, or compliance implementation.

Use when building production NLP systems, implementing text processing pipelines, developing language models, or solving domain-specific NLP tasks like named entity recognition, sentiment analysis, or machine translation.

Master orchestrator for React 19 migration. Invokes specialist subagents in sequence - auditor, dep-surgeon, migrator, test-guardian - and gates advancement between steps. Uses memory to track migration state across the pipeline. Zero tolerance for incomplete migrations.

Use this agent when you need to generate production-ready visual assets for a project — app icons, favicons, OG images, logos, wordmarks, or social media images. Invokes the prompt-to-asset MCP server to route generation requests across 30+ image models.

Optimize system performance through measurement-driven analysis and bottleneck elimination

Orchestrates work via invoke_subagent to complete ALL tasks in a todo list/plan until fully done. (Atlas - Master Orchestrator, Gemini Optimized)

Master Rust 1.75+ with modern async patterns, advanced type system features, and production-ready systems programming. Expert in the latest Rust ecosystem including Tokio, axum, and cutting-edge crates. Use PROACTIVELY for Rust development, performance optimization, or systems programming.

Create dependency-aware execution plans with explicit acceptance criteria.

Improve code quality, apply security best practices, and enhance design whilst maintaining green tests and GitHub issue compliance.

Use this agent when building Vue 3 applications that require Composition API mastery, reactivity optimization, or Nuxt 3 development with enterprise-scale performance concerns.

Terse, low-token responses. Minimal words, no fluff. Full capabilities preserved. Use when: optimize token usage, low-token mode, concise output, caveman mode, reduce verbosity, token-efficient, brief responses.

Expert Shopify development assistant specializing in theme development, Liquid templating, app development, and Shopify APIs

Run interactive runtime checks and report reproducible validation evidence.

Systematically investigate complex problems to identify underlying causes through evidence-based analysis and hypothesis testing

Use when managing Windows Server infrastructure, Active Directory, DNS, DHCP, and Group Policy configurations, especially for enterprise-scale deployments requiring safe automation and compliance validation.

Build production ML systems with PyTorch 2.x, TensorFlow, and modern ML frameworks. Implements model serving, feature engineering, A/B testing, and monitoring. Use PROACTIVELY for ML model deployment, inference optimization, or production ML infrastructure.

Runtime accessibility specialist for keyboard flows, focus management, dialog behavior, form errors, and evidence-backed WCAG validation in the browser.

Expert React 19.2 frontend engineer specializing in modern hooks, Server Components, Actions, TypeScript, and performance optimization

Use when building, refactoring, or scaling infrastructure as code using Terraform with focus on multi-cloud deployments, module architecture, and enterprise-grade state management.

Master orchestrator for React 16/17 → 18.3.1 migration. Designed for class-component-heavy codebases. Coordinates audit, dependency upgrade, class component surgery, automatic batching fixes, and test verification. Uses memory to gate each phase and resume interrupted sessions. 18.3.1 is the target - it surface-exposes every deprecation that React 19 will remove, so the output is a codebase ready for the React 19 orchestra next.

Use this agent when analyzing conversation transcripts to find behaviors worth preventing with hooks. Typical triggers include the /hookify command being invoked without arguments, or the user explicitly asking to look back at the current conversation and surface mistakes that should be prevented in the future. See "When to invoke" in the agent body for worked scenarios.
