Update Java test classes and methods to work with new code versions after refactoring or modifications. Use when code changes break existing tests due to signature changes, refactoring, or behavior modifications. Takes old and new code versions plus old tests as input, and outputs updated tests that compile and pass against the new code. Handles method signature changes, class refactoring, assertion updates, and mock modifications.

Explains test failures and provides actionable debugging guidance. Use when tests fail (unit, integration, E2E), builds fail, or code throws errors. Analyzes error messages, stack traces, and test output to identify root causes and suggest concrete fixes. Handles pytest, jest, junit, mocha, vitest, selenium, cypress, playwright, and other testing frameworks across Python, JavaScript/TypeScript, Java, Go, and other languages.

Receive and verify Shopify webhooks. Use when setting up Shopify webhook handlers, debugging signature verification, or handling store events like orders/create, products/update, or customers/create.

Receive and verify Paddle webhooks. Use when setting up Paddle webhook handlers, debugging signature verification, or handling subscription events like subscription.created, subscription.canceled, or transaction.completed.

Configure Databricks enterprise SSO, Unity Catalog RBAC, and organization management. Use when implementing SSO integration, configuring role-based permissions, or setting up organization-level controls with Unity Catalog. Trigger with phrases like "databricks SSO", "databricks RBAC", "databricks enterprise", "unity catalog permissions", "databricks SCIM".

Enforce canonical migration standards for ASP.NET Web Forms to Blazor using BWFC. Covers target architecture (.NET 10, Server Interactive), database provider detection, event handler preservation, SelectMethod patterns, and page lifecycle mapping. WHEN: "migration standards", "target architecture", "render mode placement", "page base class", "Layer 1 vs Layer 2".

Generate secure Cloudflare Worker code in TypeScript that avoids all weaknesses covered by OWASP Top 10 (2025) and CWE Top 25 (2025). Use this skill whenever the user asks to create, write, scaffold, or generate a Cloudflare Worker, CF Worker, edge function, or serverless function on Cloudflare. Also trigger when the user asks to build a secure API, secure endpoint, secure webhook handler, or any TypeScript code targeting the Workers runtime. Always use this skill over generic code generation when the target is Cloudflare Workers.

Implements Rails caching patterns for performance optimization. Use when adding fragment caching, Russian doll caching, low-level caching, cache invalidation, or when user mentions caching, performance, cache keys, or memoization.

Implements real-time features with Action Cable and WebSockets. Use when adding live updates, chat features, notifications, real-time dashboards, or when user mentions Action Cable, WebSockets, channels, or real-time.

Designs RESTful APIs with proper resource naming, HTTP methods, status codes, and response formats. Use when building new APIs, establishing API conventions, or designing developer-friendly interfaces.

Multi-language Workers development with Rust, Python, and WebAssembly. Use when building Workers in languages other than JavaScript/TypeScript, or when integrating WASM modules for performance-critical code.

Use when the user is deciding how to slice Kubernetes YAML into ConfigHub Units — phrases like "one Unit or many?", "how should I split these resources?", "should Deployment and Service be one Unit?", "where do CRDs go?", "Unit per resource or per bundle?", "should my namespace and its RBAC be together?", "per-app or per-namespace?". Applies a short set of rules (CRDs separate; rendered-from-generator stays bundled; otherwise split by ownership / references / lifecycle / blast radius) and routes the user to the right import skill with a concrete Unit-slug plan. Do not load for authoring new YAML (use `config-as-data`), for executing an import the user has already scoped (use the matching `import-from-*` skill), or when the split is already forced by the tool in use (`cub helm install` and `cub gitops import` split CRDs automatically — just run them).

Use when the user wants validation to be enforced (not just advisory) on ConfigHub Units, is setting up a new Space and wants policy to apply automatically, asks about ApplyGates, says "block bad config from being deployed", "wire up schema validation", "enforce a policy", "require approval", or needs to diagnose why a Unit is blocked from applying. This skill installs the platform-Space + Filter + TriggerFilterID pattern — centralized Triggers that run on every Mutation and attach ApplyGates when validation fails. Do not load for: running validators one-off without installing them (use cub-mutate with vet-* functions instead), or for authoring the YAML itself.

Use whenever the user wants to change data inside a ConfigHub Unit — update an image, adjust replicas, set environment variables, add labels/annotations, change a resource field, apply defaults, or make a bulk edit across many units. This skill enforces the "prefer a function over a hand-edit" rule, composes a proper change description that captures the user's prompt and clarifications, and chooses between `cub function set` (single function, targeted or bulk) and `cub unit update` (whole-unit replacement or restore). Load proactively any time the user says "update the image", "bump the replicas", "change the env var", "set the annotation", "apply defaults", "edit this unit", or any natural request that will end in a write to ConfigHub. Do not load for: creating a brand-new Unit (use config-as-data), reading/inspecting config (use cub-query), or setting up validation (use triggers-and-applygates).

Discover available tools and resources in Databricks workspace. Use when: (1) User asks 'what tools are available', (2) Before writing agent code, (3) Looking for MCP servers, Genie spaces, UC functions, or vector search indexes, (4) User says 'discover', 'find resources', or 'what can I connect to'.

Creates, updates, and deploys Power Apps generative pages for model-driven apps using React v17, TypeScript, and Fluent UI V9. Completes workflow from requirements to deployment. Uses PAC CLI to deploy the page code. Use it when user asks to build, retrieve, or update a page in an existing Microsoft Power Apps model-driven app. Use it when user mentions "generative page", "page in a model-driven", or "genux".
