How to query the document_embeddings table for raw signal data using HogQL. Use for semantic search over signals, fetching every signal that contributed to a specific report, or listing signal types. To browse the curated report layer (the Inbox)—list reports, filter by status/source, or drill into a report by ID—use the `inbox-exploration` skill first; use this skill afterward if the user wants the underlying observations
Test-Driven Development methodology and red-green-refactor workflow (formerly test-tdd). Use this skill when practicing TDD, writing tests first, designing tests before implementation, or reviewing test-first approaches. Triggers on “write tests first,” “test before code,” “red green refactor,” “test driven development.” This skill does NOT cover Vitest framework specifics (use vitest skill) or API mocking with MSW (use msw skill).
One-shot, brand-faithful presales redesign of a website page. The user provides only the URL; everything else — extraction, tension identification, three differentiated variants (one fully cinematic), validation — is derived from the captured brand surface. Use when the user asks to “uplift”, “refresh”, or “redesign a site for presales” without wanting to coordinate the extract / direct / prototype chain themselves.
This skill activates for web scraping and Actor development. It proactively discovers APIs via traffic interception, recommends optimal strategy (traffic interception/sitemap/API/DOM scraping/hybrid), and implements iteratively. For production, it guides TypeScript Actor creation via Apify CLI.
Generate animated videos and motion graphics from natural language descriptions. Creates a standalone Vite + React project with Framer Motion scenes that auto-play in the browser. Use when the user wants to create animations, motion graphics, video intros, animated presentations, or product demos
Audit cloud infrastructure (AWS, GCP, Azure) and PaaS deployment platforms (Vercel, Netlify, Heroku, Render, Railway, Fly) for misconfigurations, excessive permissions, stale or manual production deploys, and security gaps. Use when the user mentions 'cloud security,' 'cloud audit,' 'AWS security,' 'GCP security,' 'Azure security,' 'IAM audit,' 'S3 bucket,' 'cloud misconfiguration,' 'cloud hardening,' 'Vercel security,' 'Heroku audit,' 'Render audit,' 'PaaS security,' 'is production built from main,' 'old vercel.app still live,' 'preview deployments exposed,' 'Supabase RLS,' or needs to review cloud or deployment-platform security.
Perform comprehensive code reviews using OpenAI Codex CLI. This skill should be used when users request code reviews, want to analyze diffs/PRs, need security audits, performance analysis, or want automated code quality feedback. Supports reviewing staged changes, specific files, entire directories, or git diffs.
Provider-independent color grading and finishing direction for generated video, ads, trailers, product films, social clips, explainers, and mixed-source edits. Use when planning, directing, reviewing, or QAing color correction, shot matching, exposure, contrast, saturation, skin/product color protection, look development, LUT/reference use, SDR/HDR color management, delivery constraints, generated-media artifacts, editor/compositor handoff, and finishing QC
Integrate the Dynatrace Flutter Plugin into a Flutter project — dependency setup, config, SDK bootstrap, navigation tracking, and verification. Trigger: "add Dynatrace to Flutter", "Flutter plugin setup", "instrument Flutter app", "integrate Dynatrace Flutter", "mobile observability Flutter", "dynatrace_flutter_plugin". Do NOT use for: querying Flutter RUM data (use dt-obs-frontends), non-Flutter mobile setups, or Dynatrace server-side configuration.
Expert debugging and profiling for leaks, GPU/Visual Profiler, headless CI QA, orphan nodes, thread-safe logs, and custom Debugger monitors — not print/breakpoint tutorials. Trigger on OBJECT_ORPHAN_NODE_COUNT, ObjectDB growth, Visual Profiler GPU spikes, flaky headless exits, or remote device consoles. Keywords: orphan nodes, Performance.get_monitor, Visual Profiler, Time.get_ticks_usec, EditorDebuggerPlugin, headless QA, push_error, backtrace.
Query 1688 best-selling product rankings for sourcing discovery and wholesale product research. Trigger this skill when users mention 1688 product rankings, 1688 best sellers, wholesale hit products, domestic sourcing rankings, one-piece dropshipping product selection, 1688 trending products, popular items for bulk purchasing, supplier product rankings, 1688 billboard, 1688 bestsellers, sourcing rankings, wholesale hot products, trending product rankings, supplier rankings, or 1688 trends. Trigger it even if the user does not explicitly mention “1688 rankings,” as long as their request involves finding popular wholesale products or sourcing opportunities on 1688.
Migrate Python LangChain, LangGraph, or Deep Agents applications to Pydantic AI and, when the source uses harness features, Pydantic AI Harness. Use for LangChain agents, chains, LCEL, direct LangGraph graphs, persistence, interrupts, streaming, and `create_deep_agent` projects with planning, filesystem or sandbox backends, skills, memory, subagents, permissions, approvals, or Deep Agents Code hosts
Animation components and utilities for Remotion video projects. Use when building Remotion compositions with text animations, gradient transitions, particle effects, 3D scenes, or staggered motion effects. Provides example bits (complete compositions) and reusable components that can be installed via jsrepo
Reverse engineering skill for binary analysis. Use when decompiling with Ghidra, analyzing with radare2, scripting RE tools, triaging with strings/file/xxd, or diffing binaries. Activates on queries about Ghidra, radare2, r2, decompiler, Binary Ninja, Diaphora, or stripped binary analysis
Use when searching text in files, codebases, books, or documents. Use when finding files by pattern, searching large files that are too big to read fully, extracting specific content from many files, or when grep/find is too slow. Triggers on “search for,” “find occurrences,” “look for pattern,” “search in files.”
Saleor backend internals and behavior reference. Covers discount precedence, order-level discount allocation across lines (two-pass calculation, what the API does and doesn't expose, gift-line shape gotchas), stock availability modes (legacy vs direct, 3.23+), Dashboard UI rules, webhook trigger conditions, denormalized field semantics, and migration footguns. Use when working with Saleor discounts or stock availability, building Dashboard UI, building price-explanation tooling, or debugging backend behavior.
Research a specific CVE or vulnerability disclosure end-to-end — what version is affected, is your code reachable, is there a public PoC, is there a patch, what's the exposure window, what's the mitigation if you can't patch immediately. Use when the user mentions 'CVE,' 'vulnerability research,' 'is this CVE relevant,' 'zero-day,' 'CISA KEV,' 'GitHub Security Advisory,' 'reachability analysis,' 'patch analysis,' 'exploit availability,' 'EPSS,' 'CVSS,' or 'should we drop everything and patch this.'
Connect an existing front end to a live Wix site using client-only REST and its public WIX_CLIENT_ID, without an SDK or backend. Covers Stores/cart/checkout, Bookings and Rentals, Blog, Events and tickets, Portfolio, Restaurants, Donations, Forms, CMS, Pricing Plans, and Members with login, social/SSO, and gated content. Use when wiring Wix business data and buyer flows into a vibe-coded app, HTML/JSX/Vite project, or design export: shopping, appointments, donations, form submissions, memberships, restaurant orders/reservations, and member accounts. Ships dependency-free helpers and wiring guides; never provisions or changes owner content and never mocks data. Use wix-headless instead for SDK integration, Wix CLI builds, hosting, or new-site creation
Address the review findings posted on an Entire trail: fetch the trail's open findings, fix the code, and resolve them on the trail. Use when the user gives a trail URL or number and asks to address, fix, or resolve its findings or review comments. Not for local diff review — that is the `review` skill.
Use when building or auditing any web UI for accessibility: keyboard navigation, screen readers, focus management, ARIA, color contrast, form labels and error announcements, reduced motion, or touch target size. Triggers include “is this accessible”, “WCAG”, “a11y”, “screen reader”, “keyboard navigation”, “focus trap”, “contrast ratio”, “aria-label”, or building modals, menus, tabs, comboboxes, toasts, and custom controls that must work without a mouse.
Configures Laravel Nightwatch data collection, sampling rates, filtering rules, and redaction policies. Use when setting up Nightwatch, managing data volume, protecting sensitive data (PII), or optimizing event collection for production workloads.
Configures the analytics side of a PostHog experiment — exposure criteria (server-resolved default exposure event vs custom exposure events), primary and secondary metrics, the supported metric types (count, sum, ratio with `math` and `math_property`, retention with `retention_window_start` and `start_handling`), multivariate user handling ("Exclude from analysis" vs "Use first seen variant"), and how to read results once the experiment is live. Use when the user adds or edits a primary or secondary metric (e.g. "add a secondary metric tracking 'downloaded_file' per user"), sets up a ratio metric (e.g. "revenue from purchase_completed / pageviews"), sets up a retention metric (e.g. "$pageview → uploaded_file, 7-day window"), configures custom exposure (e.g. "only count users who hit /checkout"), changes multivariate handling, or asks "who is in the analysis?", "how do I measure impact?", "is this winning?", "what's the confidence level?", or "should I ship?"
Orchestrate agile development workflows for Gitea repositories using the tea CLI. Use when working with Gitea-hosted repos and asking to 'run the workflow', 'continue working', 'what's next', 'complete the task cycle', 'start my day', 'end the sprint', 'implement the next task', or wanting guided step-by-step development assistance. Keywords: workflow, orchestrate, agile, task cycle, sprint, daily, implement, review, PR, standup, retrospective, gitea, tea.
New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
