Create Nx plugins with custom generators and executors for TypeScript monorepos. Covers plugin scaffolding, Tree API usage, schema-driven options, ExecutorContext API, template generation, project-graph-safe updates, cache-aware outputs, and testable workflows. Use when creating Nx plugins, building custom generators, implementing executors, enforcing conventions, or extending Nx workspace automation.

Write and maintain Behavior-Driven Development tests with Gherkin and Cucumber. Use when defining acceptance scenarios, writing feature files, implementing step definitions, running Three Amigos sessions, or diagnosing BDD test quality issues. Keywords: bdd, gherkin, cucumber, given when then, feature files, step definitions, acceptance criteria, three amigos, example mapping.

Create tessl tiles containing docs, rules, or skills. Use when a user wants to create a tile, package content for tessl, or needs help with tile.json configuration. Also triggers on "create tile from", "convert to tile", "turn into tile", "make tile from", or "tile this repo" for existing content.

Bootstraps Flux CD on Kubernetes clusters, creates and manages GitOps sources (Git/Helm/OCI/Bucket), configures kustomizations and Helm releases, reconciles resources, sets up image automation and alerting, and pushes OCI artifacts. Use this skill whenever the user mentions the flux CLI, flux bootstrap, flux create source, flux create kustomization, flux create helmrelease, flux reconcile, flux get, Flux CD, GitOps with Flux, or asks about managing Kubernetes deployments via GitOps. Also trigger when users ask about creating Git/Helm/OCI/Bucket sources, building or diffing kustomizations, pushing OCI artifacts, setting up image automation, creating Flux alerts/receivers, or bootstrapping Flux on GitHub/GitLab/Gitea/Bitbucket. Even if the user just says "flux" in a Kubernetes context, this skill applies.

Builds Flux manifests locally, diffs YAML files, patches FluxInstance upgrades, creates authentication secrets, traces GitOps delivery pipelines, and bootstraps clusters with the Flux Operator. Use this skill whenever the user mentions flux-operator, FluxInstance, FluxReport, ResourceSet, ResourceSetInputProvider, Flux CD operator management, or asks about GitOps CLI tooling for Kubernetes with Flux. Also trigger when users ask about building Flux manifests, diffing YAML, patching Flux instances, creating Flux secrets, tracing GitOps delivery pipelines, or bootstrapping clusters with Flux. Even if the user just says "flux operator" or "flux-operator cli" without details, this skill has the authoritative reference.

Use for hands-on Pulumi CLI work: running deployments, fixing broken stacks, and managing infrastructure state. Handles: recovering from stuck or interrupted `pulumi up` with pending operations, cleaning orphaned resources from state after out-of-band cloud deletions, protecting critical resources from accidental `pulumi destroy`, moving resources between stacks without recreating them, targeting specific resources during deployment, migrating between backends (local file to Pulumi Cloud, S3), stack lifecycle management, state export/import/repair, CI/CD pipeline setup, and importing existing cloud resources. Use this skill — not the language-specific Pulumi skills — whenever the user's question is about operating, troubleshooting, or recovering Pulumi infrastructure rather than writing program code.

Add a new Java Flight Recorder event to a TamboUI module following project conventions — `dev.tamboui.AREA.THING` naming, `enabled()` guards, static `commit(...)` helper, and `compileOnly(libs.jfr.polyfill)` for Java 8 modules. Use when the user says "add a JFR event", "trace X with JFR", "instrument Y for flight recorder", or "emit a JFR event for Z".

Build a log-style or chat-style scrollable pane in a TamboUI Toolkit app — `ListElement` configured with no selection highlight, sticky scroll, scrollbar, mouse-wheel capture, focus chain integration, and a pre-wrap helper for long content. Use when the user says "build a log pane", "add a chat pane", "make a scrollable list", "trace pane that auto-scrolls", "tail-style output", or asks how to display many lines of streamed text in a TUI.

Wire keyboard and mouse focus across multiple panes in a TamboUI Toolkit app — assign stable ids, set the initial focus in `onStart()`, and add a visible focused-pane border via `focusManager.focusedId()`. Use when the user says "add multi-pane focus", "set initial focus on the input", "highlight the focused pane", "tab between panes", "make the prompt focused by default", or asks how to manage focus across panels.
