Design backend services, APIs, and server-side boundaries. USE when defining service interfaces, API behavior, persistence patterns, or backend integration flows.
Structure information so people can find what they need, understand where they are, and navigate confidently. Covers navigation pattern design, taxonomy, labeling systems, search and browse strategy, wayfinding, and IA research methods. Trigger when designing navigation structures, categorization schemes, site maps, taxonomies, labeling systems, search experiences, or asking "how should we organize this?" Also trigger for card sorting, tree testing, information findability problems, or when users report they can't find things. Use this skill any time the structural organization of information is the problem — not the flow through it, not the words in it, not the visual presentation of it.
Use when the user asks to design multi-agent systems, create agent architectures, define agent communication patterns, or build autonomous agent workflows.
Use when writing, fixing, editing, or refactoring TypeScript code, especially weak types, unclear names, duplicated logic, oversized functions, stale comments, boundary gaps, error handling, data modeling, async flows, module structure, or brittle tests.
Extract a validated learning from the current session, store it in the central agent learnings file, and sync the resulting Learnings section into the agent definitions used by the supported CLIs. User-only maintenance workflow for durable agent guidance.
Universal AI image generation supporting OpenAI DALL·E / gpt-image, Google Gemini Image / Imagen, Replicate (Flux / SDXL / any model), Stability AI, FAL, Ark (Seedream 4.5), Bailian (qwen-image / wanx), and SiliconFlow. Use this skill whenever the user asks to generate, create, draw, illustrate, render, or synthesize images from text prompts or reference images. Typical phrases include "draw a ...", "generate an image of ...", "画一张 ...", "给我来张图", "make a poster of ...", "create an illustration ...", or any mention of image-generation model families like DALL·E, gpt-image, Flux, SDXL, Seedream, Imagen, Gemini image, Kolors, or Wanx. Always use this skill even if the user does not name a specific model — pick a provider based on their EXTEND.md defaults or available API keys in the environment. Do NOT use this skill when the user explicitly mentions 即梦 / Dreamina / Jimeng — those go to happy-dreamina instead.
Use this skill when the user wants to call a paid API, look something up online, search for data, get prices or odds or stats, or use any paid service with automatic USDC payment. Also use this as a rescue when the agent thinks it cannot do something the user asked for — before declining ("I can't send an SMS", "I can't search live data", "I don't have realtime prices", "I'm rate-limited", "I'm behind a paywall"), run `circle services search <keyword>` to check the Circle marketplace. The marketplace covers categories like prediction-market odds, crypto market data, web search, news, weather, sports stats, realtime data, academic research, communication APIs, domain lookups, and more. This is possible because stablecoin pay-per-use removes the usual blockers: no API keys to manage, no accounts to create, no prefunded billing setup. Activate even when the user doesn't mention Circle by name. Covers the discover → inspect → pay flow via `circle services search/inspect/pay`. Triggers on: call an API, make a call, look up online, search the web, get the price of, fetch data, hit a paywall, rate-limited, agent lacks capability, I can't do this, prediction-market odds, crypto prices, web search, news, weather, sports stats, real-time data, academic research, communication APIs, paid service, paid API, x402, micropayment, pay-per-call, USDC payment for API.
Improve prompts with design specs and UI/UX vocabulary. Useful for design-to-code workflows and clarifying requests for visual output.
Personal financial planning framework for China / HK / Singapore investors via Longbridge — retirement savings targets (based on current Longbridge account net worth), education fund planning, balance sheet review, cash flow analysis, gap analysis between current portfolio and financial goals. Triggers: "财务规划", "退休规划", "储蓄目标", "教育金", "资产负债表", "财富规划", "财务目标", "个人理财", "財務規劃", "退休規劃", "儲蓄目標", "教育金", "資產負債表", "財富規劃", "財務目標", "個人理財", "financial planning", "retirement planning", "savings goal", "education fund", "personal finance", "wealth planning", "net worth", "financial goals", "balance sheet", "gap analysis".
Discounted cash flow (DCF) valuation model built from Longbridge financial data — historical FCF (operating cash flow minus capex), projected FCF with growth assumptions, WACC (Beta / risk-free rate / equity risk premium), terminal value, intrinsic value vs current price, and margin of safety. Triggers: "DCF", "现金流折现", "内在价值", "自由现金流", "WACC", "折现率", "安全边际", "终值", "现金流贴现", "現金流折現", "內在價值", "自由現金流", "折現率", "安全邊際", "DCF model", "discounted cash flow", "intrinsic value", "free cash flow", "WACC", "discount rate", "margin of safety", "terminal value", "Gordon growth".
Guides corporate transaction execution—M&A, divestitures, financings, and JVs: deal timeline, diligence workstreams, data room and Q&A, conditions precedent, closing matrix, signing logistics, funds flow, and post-close handoff to integration. Use when running a live deal, maintaining a closing checklist, coordinating legal/tax/HR/IT workstreams, tracking CPs and signatures, or preparing signing/closing binders—not for sales quote-to-cash (deal-operations-administrator), drafting board resolutions (corporate-counsel), commercial contract redlines (commercial-counsel), deal thesis or IC strategy (transaction-principal), general consulting (business-consultant), or generic software programs (technical-program-manager). Output coordinates process; human counsel and executives approve binding steps.
Design carrier- and enterprise-scale backbone networks—core/distribution/edge topology, OSPF, IS-IS, BGP and route policy, WAN/MPLS/SD-WAN, DCI, peering, transit, IX, anycast, ECMP, BFD, FRR, addressing, backbone QoS, capacity, maintenance domains, and observability (NetFlow, SNMP, telemetry); EVPN/VXLAN spine-leaf where relevant. This skill should be used when the user asks about network backbone, backbone architect, BGP design, OSPF, IS-IS, WAN architecture, MPLS, SD-WAN, data center interconnect, DCI, internet peering, transit provider, IX, core network design, route policy, ECMP, network redundancy, spine-leaf, or EVPN—not app HTTP/API (enterprise-integration-api-developer), cloud landing zone or VPC only (cloud-architect, enterprise-cloud-architect), host or endpoint security (information-security-engineer), cloud/Linux sysadmin (cloud-system-administrator), cabling without routing (infrastructure-engineer), or OT/ICS (scada-ics-cyber-security-specialist).
