Update static content after you have built your site using Incremental Static Regeneration (ISR).
Apply rigorous survey design principles including construct operationalization, Likert scale development, reliability and validity assessment, and common method variance control. Use this skill when the user designs questionnaires, develops measurement items, needs to evaluate Cronbach's alpha or AVE, or when they ask 'how do I operationalize this construct', 'is my scale reliable', or 'how do I control for CMV'.
Catlass Operator End-to-End Development Orchestrator. Based on ascend-kernel (csrc/ops), it connects catlass design, catlass-operator-code-gen and ascendc sub-skills to complete the closed loop from project initialization to documentation, precision, and performance. Keywords: Catlass, end-to-end, ascend-kernel, operator development, workflow orchestration.
Validate, format, and convert between JSON, YAML, and TOML. Parse and query structured data files. No API key required.
Execute read-only SQL queries against Databricks. Use when you need to run a specific SQL query, aggregate data, join tables, or answer analytical questions about Databricks data.
NestJS reference skill: modules, controllers, providers, DTOs with class-validator, TypeORM/Prisma, guards, interceptors, pipes, queues (BullMQ), WebSockets, microservices, testing, OpenAPI, and CLI scaffolding. Use when the task touches NestJS application code and should follow the project's module-based architecture.
GANG Worker Skill. You are a worker, receiving features assigned by orch, performing minimal self-checks, handing off to validator-N, and the validator will issue a verdict to the upstream.
Designs an A/B test or experiment with clear hypothesis, variants, success metrics, sample size, and duration. Use when planning experiments to validate product changes or test hypotheses.
Create, refine, review, critique, or iterate on low-fidelity grey wireframes under `stardust/wireframes/**/*.html` — structure, hierarchy, section order, spatial relationships, annotations, section metadata (`data-section`/`data-intent`/`data-layout`), and multi-page fragment/reuse mapping (`data-fragment*`). Rendered from briefings. No brand required. Optional stage: users can skip to `/stardust:prototype` for branded layout directly. Use when the user wants to validate page structure before visual design, annotate a wireframe, mark reusable fragments across pages, when the user asks to change, refine, refactor, review, improve, polish, critique, or iterate on structure, section order, or block placement, or whenever the user asks to modify a file under `stardust/wireframes/**/*.html`.
Test API behavior, contracts, security edges, and performance. USE when validating endpoints, integrations, error handling, or release readiness for APIs.
Validate pending migrations for foreign key consistency, rollback safety, and best practices
