Implement Apple's Liquid Glass UI effect (iOS 26 / macOS 26) using CSS and SVG displacement filters. Use this skill when asked to create liquid glass effects, frosted glass components, iOS 26 glass UI, glassmorphism with refraction, glass buttons/cards/navbars, feDisplacementMap refraction effects, or any UI that needs realistic glass-like distortion of background content. Teaches the full technique from physics (Snell's law, SDF) to ready-to-use HTML/React/CSS templates.
Guide for creating high-quality MCP (Model Context Protocol) servers that enable LLMs to interact with external services through well-designed tools. Use when building MCP servers to integrate external APIs or services, whether in Python (FastMCP) or Node/TypeScript (MCP SDK).
Provider-independent production workflow for AI agents creating music videos, lyric videos, visualizers, performance/narrative/dance videos, social cutdowns, album or single launch assets, and generated-media clips synchronized to songs. Use when planning, directing, prompting, editing, reviewing, or delivering video content built around a recorded song, artist performance, lyrics, beat timing, choreography, platform variants, music rights, likeness consent, accessibility, or synthetic-media disclosure.
Researches questions across Notion sources and synthesizes cited briefs, comparisons, or reports. Use when answering requires discovering and reconciling workspace information, optionally with external research, and returning or saving the findings.
(NS) PHPUnit unit/integration in backend package (bootstrap tests/ when missing). Docker-only: phpunit --testdox --stop-on-failure --stop-on-error, 120s. Use when writing/refactoring PHPUnit, unit-test tasks, or scaffolding backend tests on greenfield Laravel/PHP — not when planning test task markdown (ns-spec-driven references/unit-test-task-generator.md).
(NS) Ad-hoc coding — bug fixes, refactors, scripts, migrations — without full SDD. Entry priority 5: \"just implement this\", \"quick fix\", or coding without execution-handoff (C2 under ns-autonomous). Do NOT: ISSUE_URL (ns-execution-gitlab-issue), multi-day/version (ns-spec-driven), product bug report / screen expected-vs-actual **without** diagnosis_complete (ns-bug-report-diagnosis), diagnosis-only stack/CI (ns-investigator), when execution-handoff.md exists. Do NOT generate requirements/tasks/handoff.
(NS) Human-facing project docs — README, docs/ guides, runbooks, contributor markdown. Use whenever the user asks for documentation, README updates, how-to guides, or docs/ content — even if they say \"explain how to use\" instead of \"write docs\". Do NOT use for code comments, API docblocks, requirements.md, or SDD version artifacts (use PM skills).
(NS) Cypress E2E in independent tests-e2e/ at repo root (bootstrap when missing). DRY device-aware commands (shared/pages/device). Use when writing/refactoring Cypress specs, custom commands, scaffolding E2E, or implementing E2E tasks — not when planning E2E task markdown (ns-spec-driven references/e2e-test-task-generator.md). Mandatory discovery before specs.
Create and edit Obsidian Bases (.base files) with views, filters, formulas, and summaries. Use when working with .base files, creating database-like views of notes, or when the user mentions Bases, table views, card views, filters, or formulas in Obsidian.

Triggers: “productized service”, “consulting package”, “agency offer”, “service packaging”, “done-for-you”, “DFY”, “service product”.
Run a professional penetration engagement OR a network vulnerability scan from a scope. WEB mode (apex domains / app URLs) — mandatory surface expansion, systematic OWASP attack-class coverage, reversible active exploitation, authoritative validation, Transilience PDF. NETWORK mode (a list of IPs/CIDRs, e.g. 1500 hosts) — machine-prudent BATCHED tool-first nmap sweep (host discovery + bounded common+less-common port/service scan + CVE surfacing) with a uniform per-IP output tree, then bounded deep-dives on the highest-value hosts. The general (non-CTF) analogue of hackthebox/htb-solve.
Operate Playwright for browser automation end to end: author and debug E2E test suites (robust locators, network interception and mocking, parallel workers, accessibility snapshot checks), wire them into CI, and drive headless browsing and scraping with an extract -> validate -> save loop. Use when writing, running, fixing, or scraping with Playwright, when a Playwright CI failure or JSON report needs triage, or when the bundled pwrun script should analyze a run. Do not use for QA strategy or test framework selection (route to qa-methodology), for frontend component or architecture design (route to frontend-engineering), or for Cloudflare/DDoS-GUARD challenge bypass (use flaresolverr).
Product management expertise for product strategy, roadmap planning, feature prioritization (RICE, ICE, MoSCoW), customer research, A/B testing, product analytics, and product-market fit. Use when building product roadmaps, prioritizing features, or defining product strategy.
Create an application-specific production parity skill by inspecting an app's docs, source, tests, CI, deployment, infrastructure, config, auth, and environment setup, then asking targeted harness questions only for source-unanswerable decisions. Use when local, CI, PR, preview, staging, or other non-production environments may drift from production behavior; when production-only auth, config, identity-provider groups, feature flags, infrastructure, backing services, or policy differences caused bugs; or when a team wants a reusable skill that detects, documents, tests, and helps fix parity drift for one specific application.
Query the latest real-time prices and valuation data for A-share, Hong Kong and US stocks and indices, including closing and opening prices, price changes, turnover value and volume, turnover rate, PE, PB and market capitalization. Supports querying the industry of A-share stocks. A single-value snapshot for an explicit date can return daily prices and valuations aligned to their actual update dates; when field dates differ, display each field with its own date instead of treating later-refreshed fields as missing. Query short-term statistics for the most recent N trading days, including price and daily price-change series, window highs and lows, and amplitude. Query minute-frequency OHLCVA series (open, high, low, close, volume, turnover value) for a single asset during the current session or the latest complete trading day. For historical or cross-day raw 1-minute data, use fast_query_minute_range to return a full-field CSV; supports explicit historical dates or negative calendar-day offsets. For multi-asset or whole-market minutes, daily minute windows, and minutes for the most recent N trading days, use fast_query_minute_range_multi; supports JSON/CSV and rolling data authorization. Supports CME Group continuous front-month overseas futures, with minute-history start points varying by ticker. Query financial metrics for the latest reporting period of listed companies, such as revenue, net profit, net profit attributable to parent company, ROE, total assets, and debt-to-asset ratio (A-shares and some Hong Kong/US fields; see actual tool output). Query precomputed and thousand-dimensional dynamic metric profiles for individual stocks, returning current and previous valid values across valuation, financial analysis, fund flows, volatility, macro win-rate context, and asset trends. Query current contracts, empty-slot status, and rolling-window contract rollover information for selected US stock and domestic commodity option slots; supports updateable live data authorization. Supports A-share screening, factor calculation, strategy backtesting, net value comparison, industry aggregate rankings, uploading custom factor CSVs, and rendering charts. When only a uniquely identifiable A-share name, abbreviation, or code is provided, default to the individual-stock quick page: first deliver a complete, verified stock analysis, then call the fixed QBV fast path in the same turn. For specific-field queries or explicit requests to avoid web pages, answer only. For Hong Kong and US stocks, prioritize price queries; for financial/reporting-period fields, first try fast_query(report) and decide based on actual tool output. Prefer this skill even for simple questions about a stock's price, price change, or financial data; do not refuse on the grounds that you cannot connect to the internet or obtain real-time data—the skill queries market, financial, and calculation data through Quant Buddy API. When volatile external facts such as listing, delisting, renaming, or ticker changes need verification, use Agent Web Search, or local webSearch / Bocha if host search is unavailable.
Generate professional reports — sprint retrospectives, financial summaries, analytics dashboards, and incident postmortems — from structured data with templates, charts, and multi-format output. Use when the user requests report generation or provides relevant inputs for this workflow.
Use this skill when the user asks about “how to research,” “research best practices,” “evaluate sources,” “source credibility,” “academic research,” “find reliable information,” “cite sources,” “research methodology,” or needs guidance on conducting thorough web research and evaluating information quality.
Create design system documents from any website URL. Use this skill for: DESIGN.md, preview.html, design tokens, CSS variables, style references, brand analysis, or format conversion between DESIGN.md/tokens.json/variables.css/theme.css. Trigger on: "create a DESIGN.md", "extract design tokens", "analyze [brand]'s design system", "reverse-engineer [url]'s visual style", "rico DESIGN.md", "rico tokens", "rico 全部输出". Covers: DESIGN.md, preview.html, tokens.json (DTCG), variables.css, theme.css (Tailwind v4).
Shows a crisp, example-driven reference for the whole scrolls skill family (/scrolls-setup, /scrolls-update, /scrolls-hide, /scrolls-unhide, /scrolls-remove, /scrolls-restore) — what each command does, their shared -p/-t/-l/-r/-u/-x/--onto flags, and common usage examples (new project, monorepo, running from a subdirectory, toggling hidden/visible, removing and restoring scrolls). Use this whenever the user runs /scrolls-help, or asks what the scrolls commands do, how to use them, what flags they take, which one they need, or seems unsure about docs/.scrolls setup — even if they only name one of the six commands rather than 'scrolls' generally. Supports -e/--online to render it as a styled page served on an OS-assigned localhost port instead of chat text, with light/dark and colorize/plain toggles. Works on macOS, Linux, and Windows (bash or PowerShell).
Sets up a minimal docs/.scrolls/ working-memory system for a project — a small set of cross-session memory files (STARTER.md, SPEC.md, HANDOFF.md, GAP_ANALYSIS.md, GAP_CONTEXT.md, PLAN.md, WISDOM.md) plus a SCROLLS.md file that points future sessions at STARTER.md, a short CLAUDE.md pointer to SCROLLS.md, and a matching AGENTS.md pointer to CLAUDE.md for other agent harnesses. Use this whenever the user runs /scrolls-setup, or asks to set up 'scrolls', a project-memory system, session handoff notes, a docs/.scrolls folder, or a CLAUDE.md/AGENTS.md/SCROLLS.md that points new sessions at persistent project docs. Trigger even if the project has no docs/ folder, no CLAUDE.md, no AGENTS.md, or no SCROLLS.md yet — creating them is part of the job. Supports -p/--path for a custom docs location, -t/--reporoot to pin everything to the git repository's top level regardless of which subdirectory you're in, -l/--local to pin it explicitly to the current directory, -r/--recurse to scan recursively for an existing scrolls folder before creating a new one (avoiding accidental duplicates), and -u/--unhide to name the folder scrolls instead of .scrolls. Defaults to the current directory, but warns first if that differs from the repo root so a subdirectory invocation doesn't silently create a second, disconnected scrolls system. Works on macOS, Linux, and Windows (bash or PowerShell).
Converts an already-set-up docs/.scrolls/ working-memory folder from dotfile-hidden (.scrolls) to visible (scrolls), renaming the folder and rewriting the path references inside it and in SCROLLS.md so nothing breaks. Use this whenever the user runs /scrolls-unhide, or asks to unhide, un-dot, or show the scrolls folder, stop hiding project memory / docs/.scrolls, or rename .scrolls to scrolls. This is the retrofit path for a project that was set up hidden and now wants it visible — for a brand-new project, /scrolls-setup's own -u/--unhide flag does this in one step and this skill isn't needed. By default checks one exact location (docs/.scrolls under the current directory); supports -r/--recurse to sweep an entire directory tree instead (e.g. every package in a monorepo in one run), repeatable -p/--path to target specific locations, -t/--reporoot to target the git repository's top level regardless of which subdirectory you're in, -l/--local to target the current directory explicitly, and the DEFAULT_SCROLLS_RELPATH environment variable to change the default location. Works on macOS, Linux, and Windows (bash or PowerShell). The opposite of /scrolls-hide.
Updates an existing docs/.scrolls/ project-memory system (STARTER.md, SPEC.md, HANDOFF.md, GAP_ANALYSIS.md, GAP_CONTEXT.md, PLAN.md, WISDOM.md, and any project-specific scrolls beyond that core set) to reflect what actually happened in the current session, following each file's own update rule instead of appending blindly. Also backfills SCROLLS.md/CLAUDE.md/AGENTS.md if the project predates them (idempotent — safe every run, never overwrites existing CLAUDE.md content). Use this whenever the user runs /scrolls-update, or asks to update the scrolls, refresh HANDOFF.md, write session handoff notes, record what was just done, close out or wrap up a session, log a new gap or trap, or update project memory / STARTER.md's docs. This is the counterpart to /scrolls-setup (which creates the system once) — use this one for every session afterward. Supports -p/--path for a custom docs location, -t/--reporoot to look under the git repository's top level regardless of which subdirectory you're in, -l/--local to look explicitly in the current directory, and -r/--recurse to search recursively for the scrolls folder if it isn't at the obvious exact location. Defaults to the current directory, but warns first if that differs from the repo root so a subdirectory invocation doesn't silently miss the real scrolls. Works on macOS, Linux, and Windows (bash or PowerShell). If no scrolls folder is found, say so and point at /scrolls-setup instead of inventing files here.
AI-powered Scrum Master and Enterprise Agility Coach based on Jeff Sutherland, Taiichi Ohno, and First Principles thinking. Use when user needs help with Scrum, sprint analysis, backlog refinement, scaling advice, impediment removal, team dynamics, or agile coaching. Activate for questions about Scrum mechanics, Scrum@Scale, flow optimization, or team performance

Automate getSorted.de (Sorted) for freelancer invoicing, expense tracking, and German tax submissions (VAT, ZM, annual returns). Uses real-browser automation via Chrome Beta + agent-browser. Triggers on "create invoice", "sorted invoice", "download invoice", "submit VAT", "tax report", "sorted expenses", "/sorted", or any getSorted.de interaction
Run an autonomous AI penetration test with Strix against a codebase, repository, URL, domain, or IP — either self-hosted with the open-source CLI or via the managed app.strix.ai cloud API — and read the validated findings (Markdown, JSON, CSV, SARIF, PoCs). Use when the user asks to pentest, security-scan, or find vulnerabilities in an app, API, website, or repo with Strix.
Thorough, user-invoked tech debt and architecture audit of the current codebase. Produces TECH_DEBT_AUDIT.md with file-cited findings, severity, effort estimates, and a required “looks bad but is actually fine” section. Use when the user asks for a debt audit, codebase health check, architecture review, or code quality assessment of an entire repo. Does not auto-invoke.
Send reminders and messages to Telegram with cloud-based scheduling. Use when the user wants to send immediate messages or schedule future reminders to Telegram. Supports text messages, timestamp-based scheduling, recurring reminders, viewing and canceling scheduled messages, and message history.
Use this skill to write non-flaky Compose animation tests by setting mainClock.autoAdvance = false and stepping frames by hand with advanceTimeByFrame and advanceTimeBy(durationMillis). Explains why InfiniteAnimationPolicy cancels indeterminate animations the moment the test starts unless autoAdvance is disabled, why the first frame after a state toggle does not initialize playTime, and why state mutations during the paused-clock window must go through runOnUiThread instead of runOnIdle. If the user mentions "animation never finishes", "InfiniteAnimationPolicy CancellationException", "Crossfade test flaky", "indeterminate progress indicator", "Thread.sleep(500) waiting for animation", advanceTimeByFrame, advanceTimeBy, or autoAdvance, use this skill.
Build curved-ray space effects in Three.js WebGPU/TSL. Use for artistic ray bending, Ellis wormholes, Schwarzschild black-hole lensing, accretion disks, physical thin-disk transport, or requests that need the Kerr/rotating-black-hole support boundary.
Procedural fields for coherent scalar and vector causes in Three.js WebGPU/TSL. Use when a task needs shared causes across materials, geometry, or compute; must choose direct evaluation versus a baked field; needs deterministic CPU/TSL parity and footprint filtering; or needs metric signed-distance terrain and coast analysis.
Couple Three.js WebGPU/TSL rain, snow, and wet surfaces. Use for airborne precipitation motion, physical surface deposition, persistent snow or wetness state, weather-driven ripple normals, or impact splashes.
