Analyze Azure resource groups and generate detailed Mermaid architecture diagrams showing the relationships between individual resources. WHEN: create architecture diagram, visualize Azure resources, show resource relationships, generate Mermaid diagram, analyze resource group, diagram my resources, architecture visualization, resource topology, map Azure infrastructure.

Generates, reviews, and refactors Rails code following best practices. ALWAYS USE when working in a Rails application - this includes creating or modifying models, controllers, views, migrations, routes, tests, jobs, mailers, or any Rails-specific code. Also use when discussing Rails patterns, conventions, concerns, Hotwire, Turbo, Active Record, or Action Controller.

Use when executing implementation plans with independent tasks in the current session

Analyzes C# fields and properties and generates [JahroWatch] attributes with groups and performance-safe patterns. Use when the user wants to monitor variables at runtime, add watchers, track game state, replace Debug.Log polling, or mentions JahroWatch, real-time inspection, or variable monitoring.

Use when implementing auth in Nuxt apps with @onmax/nuxt-better-auth - provides useUserSession composable, server auth helpers, route protection, and Better Auth plugins integration.

Identifies and analyzes conflicts in software requirements including logical contradictions, technical incompatibilities, resource constraints, timeline issues, data conflicts, and stakeholder priority mismatches. Use when reviewing requirement sets, specifications, user stories, or project plans to detect conflicts that could block implementation or cause rework. Provides detailed conflict analysis with resolution strategies and impact assessment.

Applies abstract interpretation using different abstract domains (intervals, octagons, polyhedra, sign, congruence) to statically analyze program variables and infer invariants, value ranges, and relationships. Use when analyzing program properties, inferring loop invariants, detecting potential errors, or understanding variable relationships through static analysis.

Design and review APIs with suggestions for endpoints, parameters, return types, and best practices. Use when designing new APIs from requirements, reviewing existing API designs, generating API documentation, or getting implementation guidance. Supports REST APIs with focus on endpoint structure, request/response schemas, authentication, pagination, filtering, versioning, and OpenAPI specifications. Triggers when users ask to design, review, document, or improve APIs.

Conduct an interactive discovery interview to produce a structured product specification. Triggers: write a spec, PRD, feature spec, requirements, product requirements, scope a project, brainstorm a feature, flesh out an idea, plan a new project. Uses AskUserQuestion for all user choices; WebSearch/WebFetch when the user wants research. Outputs: user stories, acceptance criteria, technical constraints, prioritized requirements in docs/specs/ per SPEC_TEMPLATE.md. Do NOT use for: implementation, code review, debugging, refactors, or when the user already has a complete spec they only want edited.

Execute CodeRabbit incident response procedures when reviews stop working or block PRs. Use when CodeRabbit is down, reviews are not posting, PRs are blocked by stale checks, or CodeRabbit is producing incorrect reviews. Trigger with phrases like "coderabbit incident", "coderabbit outage", "coderabbit down", "coderabbit broken", "coderabbit emergency", "coderabbit not reviewing".

Analyze Azure resource groups and generate detailed Mermaid architecture diagrams showing the relationships between individual resources. WHEN: create architecture diagram, visualize Azure resources, show resource relationships, generate Mermaid diagram, analyze resource group, diagram my resources, architecture visualization, resource topology, map Azure infrastructure.

Use when executing implementation plans with independent tasks in the current session

Pytest-first Python testing with emphasis on fakes over mocks. Covers unit, integration, and async tests; fixture design; coverage setup; and debugging test failures. Use when writing tests, reviewing test quality, designing fixtures, setting up pytest, or debugging failures—e.g., "write unit tests for new feature", "fixture design patterns", "fakes vs mocks comparison", "fix failing tests".

Generate a structured handoff document capturing current progress, open tasks, key decisions, and context needed to resume work. Use when ending a session, saying "continue later", "save progress", "session summary", or "pick up where I left off".

Store, verify, and manage AI data on the Ethereum blockchain (Base network) using the ERCData standard. Use when an agent needs to store data fingerprints on-chain, verify data integrity, create audit trails, manage access control for private data, or interact with the ERCData smart contract. Supports public and private storage, EIP-712 verification, snapshots, and batch operations.

Self-check your own completed change before handing off to `review` — the pre-review sanity pass. Use when you want to check your work, run checks, validate changes, make sure a change is ready, test it end-to-end, run repo guardrails (lint, typecheck, tests, build), exercise the real surface with evidence, and catch obvious self-correctable issues. Produces a `ready for review` / `needs more work` / `blocked` verdict — never a ship decision. If the repo cannot be booted or exercised reliably, hand off to `agent-readiness`. If auditing someone else's diff, branch, or PR, use `review` instead.

Verifies API contracts between services using consumer-driven contracts, schema validation, and tools like Pact. Use when testing microservices communication, preventing breaking changes, or validating OpenAPI specifications.
