Use this agent when consuming or delivering webhooks — signature verification, idempotent handlers, retry and backoff policies, event ordering, dead-letter queues, or designing an outbound webhook system for your own API.

Deep-reads legacy codebases (COBOL, Java, .NET, Node, anything) to build structural and behavioral understanding. Use for discovery, dependency mapping, dead-code detection, and "what does this system actually do" questions.

Designs feature architectures by analyzing existing codebase patterns and conventions, then providing comprehensive implementation blueprints with specific files to create/modify, component designs, data flows, and build sequences

Use when you need to analyze existing metric, log, and output files to spot performance patterns and anomalies, then write a grounded, evidence-cited observability plan (what to measure, thresholds, dashboards) as Markdown.

Pulls recent production logs filtered for errors, warnings, and anomalies. Use after any deploy, after a load test, or any time you suspect something is going wrong. Treats logs as the only acceptable primary source for incident analysis — never infers from dashboards or script stdout alone.

Strategic planning and architecture assistant focused on thoughtful analysis before implementation. Helps developers understand codebases, clarify requirements, and develop comprehensive implementation strategies.

Expert Power BI report design and visualization guidance using Microsoft best practices for creating effective, performant, and user-friendly reports and dashboards.

Create interface designs, wireframes, and design systems. Masters user research, accessibility standards, and modern design tools. Specializes in design tokens, component libraries, and inclusive design. Use PROACTIVELY for design systems, user flows, or interface optimization.

Perform janitorial tasks on C#/.NET code including cleanup, modernization, and tech debt remediation.

Google Antigravity subagent code-simplifier (pr-review-toolkit)

Optional AI QA engineer (Ivy). Use when testing behavior, running automated or exploratory checks, filing reproducible bugs, verifying fixes, or providing release confidence for changes that warrant dedicated QA.

Master modern JavaScript with ES6+, async patterns, and Node.js APIs. Handles promises, event loops, and browser/Node compatibility. Use PROACTIVELY for JavaScript optimization, async debugging, or complex JS patterns.

Restricted read-only repository cartographer dispatched by the Antigravity Security scan workflow to partition the tree into components and account for every top-level directory; not for direct invocation or vulnerability research.

Expert backend architect specializing in scalable API design, microservices architecture, and distributed systems. Masters REST/GraphQL/gRPC APIs, event-driven architectures, service mesh patterns, and modern backend frameworks. Handles service boundary definition, inter-service communication, resilience patterns, and observability. Use PROACTIVELY when creating new backend services or APIs.

Formats content to be eligible for featured snippets and SERP features. Creates snippet-optimized content blocks based on best practices. Use PROACTIVELY for question-based content.

Safe Postgres migrations with zero-downtime using Neon's branching workflow. Test schema changes in isolated database branches, validate thoroughly, then apply to production—all automated with support for Prisma, Drizzle, or your favorite ORM.

Improve code quality and reduce technical debt through systematic refactoring and clean code principles

Use this agent when building X/Twitter data products, integrating X API alternatives, designing tweet search workflows, or documenting social data API usage.

Use this agent when implementing game systems, optimizing graphics rendering, building multiplayer networking, or developing gameplay mechanics for games targeting specific platforms.

Provide expert .NET software engineering guidance using modern software design patterns.

AI agent that generates simple, high-quality Python Neo4j client libraries from GitHub issues with proper best practices

Expert assistant for developing AEM components using HTL, Tailwind CSS, and Figma-to-code workflows with design system integration

Use when working on healthcare administration tasks including revenue cycle management, HIPAA/compliance auditing, medical coding (ICD-10, CPT, DRGs), CMS cost reports, payer contract analysis, quality improvement, clinical operations, health IT/interoperability, population health, and pharmacy benefits.

Review API contracts for backward compatibility, versioning, and error semantics.
