All
Qualify, score, filter, and prioritize link-building prospects by relevance, trust, editorial quality, authority, outreach fit, spam risk, and asset readiness. Use when reviewing raw URL lists, deciding which sites are worth outreach, auditing link target quality, segmenting prospects, or rejecting risky link opportunities.
Plan, audit, and prioritize linkable assets that publishers, curators, experts, and community owners have a real reason to cite. Use when creating link-worthy content ideas, auditing existing assets, turning market pains into assets, analyzing competitor linkable content, or deciding what to build before link prospecting and outreach.
Search LinkedIn posts by keywords, sorted by engagement or date. Use when researching what people are saying about a topic on LinkedIn, finding high-engagement content, identifying thought leaders, or discovering warm leads through post engagement. Returns author, post text, reactions, comments, shares, post URL, and date. No LinkedIn cookies or login required.
Explain what a specific piece of code actually does for a given input by producing a step-by-step execution trace (interprocedural, with name resolution and type transitions). Trigger when the user is confused about behavior or asks why code produces X instead of Y — "walk me through this", "trace through X with input Y", "why does this return X", "what does yield-from do here", "explain the execution path". SCOPE HARD RULE: a specific function + a specific input scenario. If the user wants to find bugs without a scenario in mind, use logic-review; two-version comparison uses logic-diff; concrete failures use logic-locate; codebase-wide audit uses logic-health. Do NOT trigger for: finding bugs without a behavioral question, style or design discussion, or concept explanations not tied to specific code.
Locate the root cause of a CONFIRMED failure via backward-then-forward semi-formal tracing. Trigger when the user provides a stack trace, failing assertion, error message, or specific wrong-value observation — "find the bug", "this test is failing", "track down this crash", "why is this test failing", "KeyError at line 89", "expected 70, got 100", "NoneType has no attribute X", "cart empties when second tab opens". SCOPE HARD RULE: requires a concrete failure (exception, failing test, or specific wrong output). Vague suspicion without evidence uses logic-review; behavior explanation uses logic-explain; refactor comparison uses logic-diff; codebase audit uses logic-health. Do NOT trigger for: vague "what's wrong" without a concrete symptom, style questions, or performance issues.
Integrate the Ludeo SDK into a Unity (C#) game using the Ludeo Unity plugin. Sets up the package install + scripting defines, wires the SDK lifecycle through MonoBehaviour/scene flow, maps and implements game actions, maps and tracks GameObjects as attributes, restores state for playable Ludeos, verifies the integration, then widens capture/restore coverage and finalizes. Use when the user asks to integrate, install, add, set up, or wire up Ludeo into their Unity game.
Periodic pass that keeps a project's verification skill and feature map honest: parallel source readers per feature, one live session driving every feature, at most one PR of proven corrections. Use for /maintain-verification-skill or "audit the verify skill".
Keep the durable record that outlives a session — credential provenance, access inventory, artifacts left on target for cleanup, findings with evidence, and a dead-end log — so work spanning days or analysts does not restart or contradict itself. Use when an engagement or investigation runs longer than one sitting, when resuming work after a gap, when handing off to another analyst, before a context window rolls over, or when you cannot say where a credential or access came from.
Design engineering principles for making interfaces feel polished. Use when building UI components, reviewing frontend code, implementing animations, hover states, shadows, borders, typography, micro-interactions, enter/exit animations, or any visual detail work. Triggers on UI polish, design details, "make it feel better", "feels off", stagger animations, border radius, optical alignment, font smoothing, tabular numbers, image outlines, box shadows.
Build a fully synthetic vertical short (1080×1920, ~40s) end to end from a topic: script + beats.json, linked TSX beats over a persistent canvas, phone-scale QA, render, ElevenLabs voice with exact word-synced captions, SFX audition, and optional music bed. Use when the user wants to “make a short,” “create a shorts video,” build a TSX short for a niche (chess, math, algorithms, dev tips, Excel…), add voice/captions to a short, or continue the short-N series in this repo. This is the 100%-TSX track—for video-model pixels use make-ai-short; for the paper-collage documentary look use make-vox. Defers raw TSX crash rules to vidtsx-2d-generator and SFX taste to suggest-sfx + brand §7.
Prevents crashes due to problematic scope-related API misuse caused by agent escalation into internal scope framework objects. Use when configuring properties of scope-related Simulink blocks or MATLAB objects — constrains the agent to documented APIs and directs users to the scope UI when a property is not programmatically accessible.
Patterns for using blockedImage to process large images, harness parallel compute for image processing, and write custom adapters. Use when writing code that creates, processes, or visualizes blockedImage objects, when implementing images.blocked.Adapter subclasses, or when a user needs help with large image data. Always use this skill when working with TIFF,GeoTIFF, .svs, .ndpi, .czi or other WSI, satellite imagery or microscopy volume image formats.
Review the implementation source code of MCP (Model Context Protocol) servers, clients, and tool handlers against a security baseline — authentication, sessions, rate limiting, input-schema validation, official-SDK usage, RCE vectors, and the OWASP MCP Top 10 — producing a report with file/line evidence. Use this skill when: - Reviewing an MCP server implementation for security before release - Checking a server against the baseline controls (MCP-01 to MCP-05) and the OWASP MCP Top 10 - Auditing tools for RCE vectors (command/code injection, unsafe deserialization, path traversal, SSTI, dependency hijacking, SSRF) - Verifying auth, session, rate-limiting, and input-validation controls on a network-exposed server - Reviewing MCP client code that handles untrusted server responses and session IDs - Requests like "review this MCP server for security" or "is my MCP server implementation secure?"
Convert markdown articles to WeChat Official Account (微信公众号) publishing format with beautiful inline-styled HTML. Use when the user wants to publish markdown content to WeChat, convert articles for WeChat public account, or mentions 微信公众号、公众号排版、公众号发布.
Harvest coding-agent session transcripts already on disk (Claude Code, Codex, OpenCode, Cursor, Pi) and extract durable knowledge — topics, people, facts, events, quotes — into whatever persistent memory the agent can reach. Cursor-tracked, budgeted, read-only on sources. Use when asked to collect/import/mine session history into memory, build memory from past sessions, or as a scheduled task. Composes with memory-gardener, which tends what this skill plants.
Resolve an in-progress git merge, rebase, cherry-pick, or revert that has conflict markers or unmerged paths, or merge a pull request's base into that pull request's branch and resolve what conflicts, from any checkout. Use when asked to mend, resolve merge conflicts, fix rebase conflicts, finish a conflicted rebase or cherry-pick, resolve the conflicts on this PR, my PR has conflicts, merge main into this branch, bring this branch up to date, /mend, or /resolve-merge-conflicts.
Loads a fitted Meridian model and generates standard visualization reports: Model Results Summary. Use when the user wants to load a saved model and view results (model performance, fit, health). Don't use for running budget optimization (use meridian-budget-optimization) or building/fitting the model (use meridian-model-building).
Generates Mermaid diagrams from codebases, topics, files, conversations, or specs. Supports flowcharts, sequence diagrams, class diagrams, state diagrams, ER diagrams, C4 architecture, mindmaps, Gantt charts, timelines, user journeys, gitGraphs, pie charts, quadrant charts, requirement diagrams, and beta types (xychart, sankey, block, architecture). Use when asked to create a Mermaid diagram, visualize a process or system, draw a flowchart, sequence diagram, class diagram, state machine, ERD, architecture diagram, mind map, timeline, Gantt chart, user journey, git branching graph, or any "diagram this" request.
Migrates existing Nango TypeScript createSync implementations from nango.lastSyncDate, legacy incremental syncType, and non-resumable full refreshes to checkpoint-based syncs. Use when updating customer Nango sync code to define checkpoint schemas, call getCheckpoint/saveCheckpoint/clearCheckpoint after every batchSave (including inside paginate loops), test dryruns with --checkpoint, and fix deletion handling for checkpointed incremental or full syncs.
Generate Minecraft item/block textures (16x16 / 32x32 PNG) from AI-generated art. Use when the user asks to create, convert, or post-process Minecraft textures — e.g. "生成一个原味鸡的 MC 材质" or "把这张图做成 16x16 的 Minecraft 材质" — including white-background removal and per-block color sampling. Pairs with the `imagegen` skill for generation and the `minecraft-modding` skill for using textures in mods.
Make a web interface feel native on a phone. Touch targets, dynamic viewport height, safe areas, tap highlight and sticky hover, input zoom, touch-action and overscroll, sheets and bottom bars in the thumb zone, the on-screen keyboard, momentum and pull-to-refresh conflicts, and performance on a mid-range device. Use when a site "feels like a website" on mobile, when building bottom sheets, bottom navigation or mobile forms, or before shipping anything people will use on a phone.
Make a web app feel native on a phone—the small CSS and meta-tag fixes that separate “a website in a browser” from something that feels installed. Covers sticky hover states, tap highlight flashes, the 100vh bug, inputs that zoom the page, laggy taps, pull-to-refresh hijacking scroll, content under the notch, long-press selecting button text, carousels that scroll the wrong way, mismatched status bars, and the rule that you test on real hardware. Use when a web app is being built for or reviewed on mobile, when something “works in Chrome but feels wrong on my phone,” when building a PWA, a bottom sheet, a carousel, a full-screen layout, or any touch interaction. For motion itself use animate; for React Native use animate-expo.
Automatic model fallback and failover. When the primary model's request fails, times out, hits rate limits, or runs out of quota, it automatically switches to a backup model to keep service continuity. Supports intelligent model selection across multiple providers and priorities, with health monitoring, automatic retries, and error recovery mechanisms.
MOEX ISS and ISS+ mechanics for raw REST endpoints, public iss.moex.com access, authenticated apim.moex.com access, output formats, iss.only, iss.json, start pagination by returned row count, response block normalization, discovery and history routes, calendars, boardgroups, and websocket/STOMP concepts.
Optional, modular cleanups and style improvements to apply on new mo:core projects (or after mo:core migration). Covers import ordering, unused import cleanup, and single‑expression return removal, with detection checks and automation recipes.
Chinese web-novel character naming. Use when the user needs names for protagonists, female leads, villains, supporting characters or elders, wants to rename them, finds the names too common/too AI/overused (such as 叶辰苏念林婉儿), or says "I can't come up with names". Produces fitting, memorable character names by genre/era/status/gender, avoiding the cookie-cutter names churned out by web-novel pipelines.
Use when creating any quest, mission, or story content — enforces the 5-step narrative coherence check: lore validation, conflict detection, quest registry, and contradiction prevention. Triggers: coherence check, lore validation, quest registry, narrative consistency.
Draft, restructure, or plan Nature-style manuscript sections from author-provided claims, results, figures, notes, or Chinese drafts. Use when the user wants to write or rebuild an abstract, introduction, results narrative, discussion, conclusion, title, or full manuscript argument rather than only polish finished prose
Guides and best practices for working with Lakebase Postgres on Neon: connections, pooled vs direct, schema migrations, branching, autoscaling, scale-to-zero, instant restore, read replicas, IP allow lists, logical replication, and Lakebase Search. Use when the work is an existing DATABASE_URL, SQL, schema, inspect, or search. New backends, Auth, files, Functions, and LLM calls go to the parent `neon` skill. Also use for "@neondatabase/serverless", "@neondatabase/neon-js", "neon inspect db", "semantic search", "vector search", "full-text search", "BM25", or "hybrid search".
End-to-end automation patterns with NetBox — event-driven workflows (event rules, webhooks), infrastructure-as-code (Ansible, Terraform), and GitOps integration. Use when building, advising on, or troubleshooting NetBox automation pipelines.
Add or change a capability of a Boring app - an agent, a job, a chat, a tool, a view or a page - and decide whether to expose it in boring.json. Use when a task asks for a new agent or output field, a change to an agent's prompt, rules, model or output, work that runs several agents, a chat, a tool an agent or the hub calls, or a view the hub frames. Lists the files to create, the contracts to keep, the tests to run and the feature-map entry to update.
Use for security-sensitive Next.js backend-for-frontend work involving Route Handlers, Proxy, Server Actions, webhooks, callbacks, data access layers, server-only modules, request validation, rate limits, or public API boundaries. Prefer this skill when a Next.js task exposes HTTP endpoints or moves privileged data across server/client boundaries.
Set up reproducible dev environments via devbox (Nix-backed) or pure Nix flakes. Templates for MoonBit, Rust, TypeScript+pnpm, Python+uv, Haskell, OCaml, OxCaml preloaded with just / ast-grep / apm. Covers devbox.json, buildNpmPackage, direnv, GitHub Actions, and bootstrapping in sandboxed envs (Claude Code web). Use when starting, adding, or troubleshooting a Nix or devbox setup.
A world-class PPT design architect that turns source material (speech scripts/topic keywords/outlines) into directly executable PPT design plans. Use for: (1) generating PPT design prompts from a speech script, (2) expanding topic keywords into a full PPT design plan, (3) choosing the best visual form for a content outline, (4) generating design parameters that match brand visual guidelines, (5) outputting generation instructions usable by tools such as Gamma Pro.

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.
