Development
Expert-level JavaScript development with modern ES2024+ features, Node.js, npm ecosystem, and best practices. Use when the user mentions ECMAScript, ES2024, Node.js, npm, or web, or when the task involves Modern JavaScript, Node.js Development, Modern Tooling, or Functional Programming.
Gauge the user's technical + product knowledge through 7 adaptive questions, log verbatim answers with honest ratings, and grow a learning plan from the gaps found. Use when the user says “level up”, “level-up session”, “quiz me”, “gauge my knowledge”, or wants a new assessment round. Differentiator: this finds and maps gaps; the `teach` skill delivers lessons on them.
Work safely with endpoint versions — preview a draft in the playground, roll back to an older version, update settings on one version without bumping query history, deactivate a specific version. Use when the user asks "how do I roll back my endpoint", "preview my changes before publishing", "I want to fix v5 without bumping the version", or anything involving the version history. Calls out today's limitations honestly: there is no pointer flip; "rollback" means forking the old query into a new top version.
Orchestration skill for NVIDIA Nemotron Speech (Riva) / NeMo ASR domain and language adaptation. Given a goal like “improve/fine-tune ASR for my domain or language,” it scopes the task, picks the cheapest sufficient path (word boosting → n-gram LM → fine-tuning), delegates each stage to the right sub-skill (data generation, training, evaluation, deployment), and answers cost, time, and data questions along the way.
Generate code using Nx generators — scaffold projects, libraries, features, or run workspace-specific generators with proper discovery, validation, and verification. Use when user says "create a new library", "scaffold a component", "generate code with Nx", "run a generator", "nx generate", or any code scaffolding task in a monorepo. Prefers local workspace-plugin generators over external plugins. Do NOT use for running build/test/lint tasks (use nx-run-tasks) or workspace configuration (use nx-workspace).
This skill should be used when the user asks to "migrate from Phaser 3", "upgrade to Phaser 4", "convert my v3 game", "Phaser 3 to 4 migration", "update Phaser version", "my Phaser 3 game broke after upgrading", "behavior changed after upgrading Phaser 4", "upgrade Phaser 4.0 to 4.2", or has code that uses deprecated or removed Phaser 3 APIs or behavior that silently drifted between Phaser 4 RC releases.

Enforces feature state as one Notifier/AsyncNotifier/StreamNotifier ViewModel over an immutable state value with value equality, private mutable state mutated only through intent methods, derive-don't-store, a single write path through a repository, and unidirectional data flow; Riverpod 3.x is DI (providers-as-collaborators, ProviderScope overrides per flavor, throwing seams), reads split ref.watch/.select for display vs ref.read(p.notifier) in callbacks vs ref.listen for side effects, async modeled as AsyncValue, per-entity state family-keyed + autoDispose, and stale-closure captures / legacy StateProvider-StateNotifierProvider-ChangeNotifierProvider / get_it / package:provider are banned. Use when adding state to a screen, writing a feature controller/ViewModel, wiring providers or DI, deriving a read model from a stream, or reviewing rebuild/state-leak/disposal/write-path issues.
Use this skill whenever the user wants to write code using TDD, test-driven development, or test-first methodology. Triggers on: "/tdd", "let's do TDD", "write a failing test", "red green refactor", "test-first", "start a TDD cycle", or any request to implement a feature by writing tests before code. Adaptive five-step cycle (RED-DOMAIN-GREEN-DOMAIN-COMMIT) that detects harness capabilities and routes to guided (/tdd red|domain|green|commit) or automated (/tdd) mode. NOT for running existing tests, debugging test failures, or reviewing code -- only for the disciplined test-first cycle.

Migrate an existing documentation site (Mintlify, Docusaurus, Fumadocs, Nextra, Starlight, VitePress, VuePress, Docus, MkDocs, mdBook, Fern, GitBook, ReadMe, Redocly, Docsify, Jekyll (Just the Docs), GitHub Wiki, or any docs framework) to Blume, the markdown-first docs framework on Astro. Translate the source config to blume.config.ts, restructure content into Blume's filesystem-derived navigation, rewrite JSX callouts to directives, convert icons to Lucide, and inline snippets. Use when the user asks to migrate/convert/port a docs repo to Blume, or when the repo has a docs.json/mint.json, docusaurus.config.*, meta.json with fumadocs, _meta.* with nextra, an astro.config.* with starlight(), a .vitepress/config.* or .vuepress/config.*, an mkdocs.yml or zensical.toml, a book.toml (mdBook), a fern/docs.yml, a GitBook .gitbook.yaml/gitbook-docs.yaml, ReadMe _order.yaml files in docs/ or reference/, a Redocly sidebars.yaml or @redocly/realm dependency, an index.html that sets window.$docsify, a docus or @nuxt-themes/docus dependency, a Jekyll _config.yml (Just the Docs theme), or a GitHub wiki clone (Home.md with _Sidebar.md, [[Page Name]] links).
Build the site-facing parts of an EmDash CMS project on Astro, including schema and seeds, content queries, Portable Text rendering, menus, taxonomies, widgets, and deployment configuration. Use for EmDash site and theme work; use creating-plugins instead when the task is plugin authoring alone.
Add a remote service integration to an existing CAP Node.js application using the Calesi pattern. Imports external APIs (from other CAP apps or OData/S4 sources), creates consumption views, wires up delegation and data federation handlers, and validates the result with cds watch. Use when a developer wants to consume an external service in their CAP app.
Produce a design-system adoption plan for a product — tear down its bespoke UI, map every custom pattern to its design-system replacement, estimate the effort, and hand back a prioritized, phased build schedule. Use when the user wants to adopt, migrate to, or fully embrace a design system in an existing product, asks "what would it take to move this to our design system?", wants custom CSS replaced with system components, or asks for an adoption/migration plan or estimate. Companion to ds-inspection and product-inspection — the inspections find the warning lights; this produces the restoration estimate and build schedule.
Design an auditable playbook when no narrower one fits: a large migration, an ambitious multi-part change, or work a human reviews after stepping away. Scale rigor to the task, run a hypothesis loop, and log decisions. Use for /figure-it-out or "figure it out".
Selects how functions are invoked — synchronous calls that return results, fire-and-forget void dispatches, or durable enqueue through named queues with retries. Use when deciding between blocking RPC calls, background job dispatch, async workers, or reliable message delivery with acknowledgement.
Orchestrates durable multi-step workflow pipelines on the iii engine. Use when building order fulfillment, data pipelines, task orchestration, or any sequential process requiring retries, backoff, step tracking, scheduled cleanup, or dead letter queue (DLQ) handling.

Sanitize MDX content for Docusaurus builds. Fixes unescaped angle brackets (<, >, <=, >=), Liquid/Nunjucks template syntax ({{ }}), TypeScript generics (Promise<T>), and inline code backtick edge cases. Use when pre-commit hooks fail on bracket or Liquid validation, or when MDX/JSX build errors reference unexpected tokens. NOT for general markdown linting or prose editing
(NS) Spec-driven delivery — clarify requirements, define tasks (including unit/e2e), implement, and resume/continue a version from disk. Entry priority 2: feature specs, version work, multi-day scope, or “continue” / “resume version” when docs/versions/ has partial artifacts. Bare quick fixes: ns-coder. Do NOT use for brownfield onboarding, architecture rules, or /ns-harness prepare (never auto-run Prepare).
