Comprehensive software architecture skill for designing scalable, maintainable systems using ReactJS, NextJS, NodeJS, Express, React Native, Swift, Kotlin, Flutter, Postgres, GraphQL, Go, Python. Includes architecture diagram generation, system design patterns, tech stack decision frameworks, and dependency analysis. Use when designing system architecture, making technical decisions, creating architecture diagrams, evaluating trade-offs, or defining integration patterns
Use when the main problem is a noisy or aliased analog/ADC signal and the task needs signal-chain diagnosis or filter-path selection across sampling, anti-aliasing, RC/input conditioning, ADC source impedance/settling, latency, startup, saturation, or raw/fault observability. Apply it when software filtering and hardware signal conditioning interact, even when the request only says that an analog sensor is unstable. Hand reusable Arduino snippets to arduino-code-generator, board facts to board-support, voltage/pin/rail safety to wiring-safety-check or circuit-debugger, and calibration after detection to sensor-calibration-workbench.

Analyze and optimize websites for search engine visibility. Use when asked to run an SEO audit, improve page rankings, fix meta tags, add schema markup, generate a sitemap, optimize for Core Web Vitals, or when user says "improve my SEO", "audit this site's SEO", or "help me rank higher on Google".
Use this skill when a B2B or SaaS site needs an SEO content roadmap grounded in commercial reality — the user asks for "topic research", "keyword research", "an SEO content plan", "what should we publish to rank", or wants organic pipeline from Google and AI search rather than traffic. It runs seven phases — business context ingestion, opportunity extraction, keyword validation, SERP qualification, business fit filtering, topic shaping, and prioritization — and produces a tiered, sequenced topic plan ready for briefing. Each phase is also available as its own standalone skill in the library.
Write, debug, and optimize Shadertoy shaders and GLSL fragment shaders for procedural graphics. Use when creating visual effects, generative art, or WebGL shaders; when writing .glsl files; or when user says "write a shader", "make a Shadertoy effect", "help with GLSL", or "create a procedural animation".
Use when the user wants to manage a shoplazza store's product catalog through the CLI — creating / publishing / unpublishing products (建品 / 新建商品 / 上新 / 上架 / 下架), searching or counting the catalog (搜商品 / 找商品 / 商品数量 / how many products I sell), changing prices (改价 / 调价 / set price), adjusting stock (库存 / 补货 / 加库存 / 减库存 / inventory), product tags (标签), variants / SKUs (变体 / 规格), collections and collects (商品合集 / 商品分组), product images (商品图片 / 主图), gift cards (礼品卡 / 储值卡 — gift cards live HERE, not in discounts), customer product reviews (买家评价 / 评论 / product reviews), warehouse locations (仓库 / 库位), suppliers and procurement (供应商 / 采购单 / 进货). NOT discount codes / coupons / 优惠码 / 折扣码 / 满减 (→ shoplazza-discounts); NOT the store media library / file uploads / 媒体库文件 and NOT metafields / 元字段 (→ shoplazza-shop); NOT order fulfillment / 发货 (→ orders domain); NOT theme card images / 装修配图 / 商品详情页模板 (→ shoplazza-themes)
Provide implementation guidance for Sileo (npm package "sileo") toast notifications in React apps. Use when adding the Toaster viewport, firing global toasts via sileo.success/error/warning/info/show/action, handling async flows with sileo.promise, dismissing/clearing toasts, configuring positions/offset, theming with light/dark/system modes, and customizing styling via fill, styles overrides, autopilot, roundness, CSS variables, and data-attribute selectors. Also use this skill for swipe-to-dismiss behavior, custom icons, JSX descriptions, reduced-motion support, TypeScript type exports, and understanding Sileo's internal SVG gooey morphing architecture. Make sure to use this skill whenever the user mentions sileo, toast notifications in React, gooey toasts, physics-based notifications, or wants to add any kind of toast/notification system using sileo, even if they don't explicitly name the package.
Creates, audits, and consolidates Agent Skills that follow the Agent Skills open standard, and hands back a drafted or repaired skill with the review checklist for its branch applied. Use for "create a skill", "draft a SKILL.md", "package this expertise as a skill", "why does this skill never trigger", "audit this SKILL.md", "improve this skill", or merging overlapping skills into fewer deeper modules. Covers frontmatter, descriptions that trigger, progressive disclosure, completion criteria, and bundled scripts.
Guide creating and reviewing skills that extend Claude with specialized knowledge, workflows, or tool integrations. Covers SKILL.md structure, frontmatter quality, trigger design, eval pipelines, and packaging. Triggers on create a skill, review this skill, new skill, optimize skill, skill quality.
Slack API integration with managed OAuth. Send messages, manage channels, search conversations, and interact with Slack workspaces. Use this skill when users want to post messages, list channels, get user info, or automate Slack workflows. For other third party apps, use the api-gateway skill (https://clawhub.ai/byungkyu/api-gateway).
Turn a data file (CSV/TSV/TXT/XLSX/XLS/JSON) into standalone interactive ECharts HTML charts - 26 chart types, 3 themes, fully offline with no CDN. Each chart ships with an embedded fact sheet (plot_stats plus data_preview) whose numbers are the only values an agent may quote in its caption: this is chart generation with traceable facts, not data analysis or report writing. TRIGGER: user supplies or points to a tabular data file and wants a chart; asks to 画图/出图/可视化/生成图表/generate a chart/make a graph; wants a table rendered as an interactive HTML chart. DO-NOT-TRIGGER: wants a written report, narrative analysis or slide deck; no data file is supplied; geo/map rendering; dashboards needing a backend; images, audio, video or other non-tabular content.
When the user wants help creating, scheduling, or optimizing social media content for LinkedIn, Twitter/X, Instagram, TikTok, Facebook, or other platforms. Also use when the user mentions "LinkedIn post," "Twitter thread," "social media," "content calendar," "social scheduling," "engagement," or "viral content." This skill covers content creation, repurposing, and platform-specific strategies.
Social Media Manager role skill. Orchestrates the full SMB social media workflow across three layers — Foundation (brand setup + calendar), Content Creation (captions, platform-specialist posts, visuals), and Distribution (scheduling via Blotato + performance review). Coordinates all 9 component skills as a sequential, human-reviewed pipeline. Run this skill instead of invoking component skills individually.
Build and execute a social media marketing strategy for a solopreneur business. Use when choosing platforms, creating a posting strategy, growing followers, increasing engagement, or driving conversions from social media. Covers platform selection, content planning, engagement tactics, organic growth strategies, and analytics. Trigger on "social media marketing", "social media strategy", "grow my social media", "LinkedIn strategy", "Twitter marketing", "Instagram for business", "social media content", "increase social engagement".
Social-SBTI — scrapes public activity from Jike / X and generates a spoof SBTI personality card. Wizard-style flow: user triggers → pick platform → paste URL → automatic check/configure credentials/scrape/score/render → card output. Trigger scenarios: - user says "跑一下 social-sbti" / "启动 social-sbti" - user says "帮我分析 @某某 的 SBTI" - user says "用 social-sbti 分析 @某某" - user says "给 XXX 来个社交版 SBTI 人格卡"
Calculate the right price for custom software projects ($8K-$50K+) based on complexity, value delivered, and client ROI. Includes justification, pricing tiers, negotiation strategies, and ROI calculations to present to clients.
Drive an evidence-driven, iterative product+engineering spec process that produces a full PRD + technical spec (often as SPEC.md). Use when scoping a feature or product surface area end-to-end; defining requirements; researching external/internal prior art; mapping current system behavior; comparing design options; making 1-way-door decisions; negotiating scope; and maintaining a live Decision Log + Open Questions backlog. Triggers: spec, PRD, proposal, technical spec, RFC, scope this, design doc, end-to-end requirements, scope plan, tradeoffs, open questions.
Engage the User to resolve important open decisions in Spec Loop work, including tasks, plans, design updates, work breakdowns, implementation checkpoints, and ADR drafting. Use when the user asks to clarify, compare options, discuss criteria, or stress-test, or when different answers could materially change scope, behavior, policy, constraints, route, Design, Test specification, or ADR content. Provides mandatory decision screening for workflows that require it before dependent Spec Loop content is written or revised. Also use for general grilling when explicitly selected.
Create specs, describe an existing project, update agreed contracts as behavior changes, or review specs against implementation. Infer spec-init, spec-onboard, spec-update, or spec-review from intent and evidence. Use spec-update for the canonical part of an authorized implementation change; keep code and user documentation in their own steps. Activate yourself after completing an authorized change that alters material behavior, compatibility, or a security boundary when specs/ exists; this trigger is owned by the skill and needs no project instructions. Russian discovery terms: спецификация проекта, обновить спецификацию, проверить спецификацию.
Pure-web protocol reverse skill: turn hostile browser clients into browser-free Python collectors. Auto-judge intake and tool path: artifact-only when samples suffice; fresh web live-target needs sequential fingerprint-baseline then debugger-trace (default chrome-devtools then js-reverse; if DP is already required js-reverse may own both roles on one host and must not launch a second Chrome; replay identity locks to installed curl impersonate; unknown risk-control does not bulk-add unproven extra routes; Camoufox/managed baseline only on fingerprint pressure; silent-value-capture is a first-class debugger-trace means when attach is missing or page-world capture is insufficient/observer-toxic). Continuation reuses the current gate. Route only mounted web MCP families. Out of scope as primary path: APK, native app, mini-program. Use for hostile web sign, token, cookie, WebSocket, GraphQL, protobuf, response-decode, fingerprint, WASM, challenge-bootstrap, dynamic-font, or protocol-collector flows
The sports-highlight-editor skill analyzes raw game footage and automatically identifies peak moments — goals, dunks, sprints, saves, and crowd reactions — then assembles them into a polished highlight reel. Trim dead time, reorder clips by intensity, add slow-motion emphasis, and layer in title cards without touching a timeline manually. Built for coaches, athletes, content creators, and sports media teams. Supports mp4, mov, avi, webm, and mkv formats.
SQL injection screening for host code (MoonBit / TS / Rust) plus secretlint setup notes. Flags single-line template-literal or string-concat SQL builders, regardless of value source — the scanner is line-based and does NOT trace data flow, so a clean scan is not proof of safety (multi-line template literals are missed) and every hit needs a manual review or an explicit `// sql-security: ok` opt-out.
Interactive naming convention standardization for TMDL-based Power BI semantic models. Automatically invoke when the user asks to "standardize naming conventions", "fix naming conventions", "clean up model names", "apply naming standards", "audit naming", "make names human readable", "rename fields", "fix abbreviations in model", or mentions renaming measures, columns, or tables for consistency across a model.
Design every state a screen can be in, not just the happy one. Loading with skeletons that match the layout, spinner timing, empty states that teach one action, partial and stale data, errors that say what to do, optimistic updates and rollback, streaming, offline, unsaved changes, and success that does not interrupt. Use when building any screen that fetches, submits or can be empty, or when a screen “flashes”, “jumps”, or shows a spinner over everything.
Fetch announcements from A-share listed companies (real data). Based on AkShare, retrieves all announcements of the day from East Money, with filtering by stock code and keyword. Suitable for monitoring key information for investment decisions such as major events, earnings flash reports, shareholder changes and restructuring announcements. Data source: East Money (stable and reliable).
Step one of A-share technical analysis (data acquisition and minimal validation). Strictly prioritize tushare-mcp (calling tushare-pro.* via mcporter) to pull daily bars, technical factors, and capital flows and save them to results/project-name/data/raw.
