Implement or review advanced Flutter visual rendering such as frosted or liquid glass, backdrop blur, refraction, shaders, custom painting, glow, masks, and effect fallbacks. Use when the request explicitly needs a nontrivial visual effect; route art direction, ordinary styling, animation timing, and evidence-based performance diagnosis to their dedicated skills.
Create production-ready frontend interfaces with high design quality. Use this skill when the user asks to build Web components, pages, posters, or apps (such as official websites, landing pages, dashboards, React/Vue components, HTML/CSS layouts, or to style/beautify any Web UI). Produce creative, polished code and interface designs that avoid "generic AI aesthetics".
Installs and manages Freshworks Development Kit (FDK) with Node.js via nvm for Platform 3.0 development. Supports FDK 10.x (Node 24, recommended) and FDK 9.x (Node 18, deprecated May 31, 2026).

Discover external customer problems and product requirements from human stakeholders. Assess customer evidence before investing, or map who to talk to, ask questions that surface hidden assumptions, detect gaps in real time, resolve conflicts, and translate conversations into structured SDD specs. Phase 0 upstream of Spec-Driven Development. Also grill a PRD, interrogate a proposal, poke holes in a spec, or interview its author about an existing draft, one consequential question at a time. Do not use for personal-life discovery (daily-life-discovery), general research without product requirements (research-methodology), or implementation planning.

USE WHEN: user mentions "Socket.IO", "socket.io", "real-time chat", "live updates", "bidirectional WebSocket", "rooms", "namespaces" DO NOT USE FOR: SSE (server-sent events) - use `sse`; WebRTC - use `webrtc`; raw WebSocket without Socket.IO - use framework WS skills
Build a certification-compliant first-run setup page for a Splunk app or add-on that collects non-secret settings via the configurations REST endpoint and secrets via storage/passwords, wires app.conf/default.meta correctly, and avoids the deprecated setup.xml mechanism. Use when the user wants a "Set up your app" screen, first-run configuration wizard, or a way to collect an endpoint/credential/API token for a Splunkbase app or TA. Route general app packaging, compatibility, upgrade, or removal lifecycle guidance unrelated to the setup page itself to app-and-add-on-lifecycle-advisor, and broader knowledge-object governance beyond this app's own default.meta to knowledge-object-governance.

Use when the user asks about Spring Cloud, needs to build microservices, implement service discovery, or work with Spring Cloud components.
Use this skill when writing the code inside a Stackbone workspace with @stackbone/sdk: authoring a deep agent (deep-agents/<name>/index.ts default-exporting defineDeepAgent({ name, model, tools, subagents, interruptOn }) from @stackbone/sdk/deep, whose instruction is NOT in the code but a catalogue prompt owned by the agent, with LangChain tools and connectorTool(...) for third-party operations), writing durable workflows as 'use workflow' / 'use step' functions in workflows/<name>.workflow.ts with sibling inputSchema / outputSchema, calling a sibling agent from a workflow step with callDeepAgent / streamDeepAgent from @stackbone/sdk/workflow, and reaching the ambient `stackbone` client from a tool or a step: stackbone.database (Drizzle over the agent's Postgres), stackbone.storage, stackbone.ai, stackbone.rag, stackbone.config / secrets / settings / prompts, stackbone.workflows (start or schedule another workflow) and stackbone.connection(id) for a connector, plus human-in-the-loop both ways (requestApproval() in a workflow body, tool-level interruptOn in an agent). Trigger on requests like: build an agent, add a tool, write a workflow, store data, upload a file, call an LLM, ingest docs for RAG, pause until a human approves, gate a tool behind approval, call another agent, call a connector, read dynamic config, give an agent a browser, run a workflow serially. For CLI tasks (init, add, dev, build, db migrate, runs, hitl) use the stackbone-cli skill; to triage an error or a stuck run use stackbone-debug; to start a new piece from a description use stackbone-coder.
