Knowledge Agent

Build or redesign polished browser-rendered visual artifacts with HTML/CSS/JavaScript/React: pages, dashboards, prototypes, slide decks, animations, UI mockups, and data visualizations. Use for visual front-end creation, design-system exploration, design critique, or explicit browser acceptance / QA of a web artifact. Not for back-end, CLI, non-visual coding, source-to-longform article conversion, or narration-driven click-through video presentations.

Use when building Next.js 14+ applications with App Router, server components, or server actions. Invoke to configure route handlers, implement middleware, set up API routes, add streaming SSR, write generateMetadata for SEO, scaffold loading.tsx/error.tsx boundaries, or deploy to Vercel. Triggers on: Next.js, Next.js 14, App Router, RSC, use server, Server Components, Server Actions, React Server Components, generateMetadata, loading.tsx, Next.js deployment, Vercel, Next.js performance.

Build agent-facing web experiences with ATXP-based authentication, following the ClawDirect pattern. Use this skill when building websites that AI agents interact with via MCP tools, implementing cookie-based agent auth, or creating agent skills for web apps. Provides templates using @longrun/turtle, Express, SQLite, and ATXP.

Agent Platform Model Tuning. Use when you need to fine-tune open models or Gemini models using Agent Platform infrastructure. Don't use for model training outside Agent Platform, model deployment to endpoints (use `agent-platform-deploy`), or managing serving endpoints (use `agent-platform-endpoint-management`).

Registers LLM tools and renders custom tool-call UI in assistant-ui (@assistant-ui/react). Covers the current authoring model: a "use generative" file exporting defineToolkit({...}) that co-locates schema, execute, and render and is split across the client/server boundary by the build plugin (withAui from @assistant-ui/next, aui() from @assistant-ui/vite, withAui from @assistant-ui/metro), mounted with Tools({ toolkit }) through useAui and exposed to the model with AISDKToolkit. Covers the tool kinds and their execute markers: backend (plain execute), frontend ("use client" inside execute), human via humanTool()/hitl, provider via providerTool(), external via externalTool(), stubs via stubTool() plus useAuiToolOverrides, and MCP via defineMcpToolkit. Also covers the component-scoped path (makeAssistantTool / useAssistantTool / makeAssistantToolUI / useAssistantToolUI), ToolCallMessagePartProps (status.type running/complete/incomplete/requires-action, args, argsText, result, artifact, a

Front door for any GTM task on Cargo — sourcing, waterfall enrichment, email/phone/LinkedIn lookup, email verification, scoring, qualification, sequencing, CRM sync, and signal monitoring (job changes, funding, tech-stack/hiring intent). Use when the user states a real-world goal involving prospects, leads, accounts, contacts, ICP lists, or campaign activation. Routes to phase guides (Level 2), recipes (Level 2.5), and per-provider playbooks (Level 3) before any action call.
