Send an independent judge that is not the author: a fresh evaluator subagent that checks finished work against pass criteria written before it was built (evaluator mode), or audits a batch against its source of truth (audit mode), with evidence for every verdict and never a fix. Use when the owner asks for an evaluator, reviewer, auditor or judge, or says 'send a judge', 'evaluate this', 'check my work with a fresh agent', 'get a second agent to review this', 'audit this folder', 'audit my registry', 'verify this against the source of truth', or 'LLM-as-judge'. Runs only when asked; it does not fire on its own at the end of a task. Not for checks a machine can run (tests, schema validation, a search that must return zero), not for hundreds of identical units, and not for fixing anything.
Use when an agent needs live China travel data — geocoding, POI search, driving routes and map tiles (高德 Amap), flight schedules, transfers and fares (飞常准 Variflight), high-speed rail tickets (携程 Ctrip), weather and city coordinates (Open-Meteo) — or the planning order and mode trade-offs behind a trip. Triggers on 查航班 / 查火车票 / 查天气 / 查景点坐标 / 查驾车距离 / 行程该先定什么. Not for generating a full itinerary or shortlisting attractions.
Google Cloud (GCP) assistant and operator via the autocloud MCP server. Use for any GCP request: how-to, resources, Terraform/Kubernetes/Helm, rollouts, incidents, or costs. Invoke it before answering a GCP question from your own knowledge or documentation search, and before proposing an architecture or backend—even when no cloud is named. Invoke it before reading or editing local *.tf or Kubernetes YAML files. Don’t use it for non-GCP tasks or local machine setup, such as installing gcloud and setting up GCP.
Finds, buys, or connects a custom domain (e.g. meinladen.ch) for the Albatros server. Explains domains and DNS with the analogy of an address and phone book, suggests names, checks availability with domain_suchen, and buys through Albatros using domain_kaufen (the person is the owner and enters their details only on the payment page). If the person already has a domain, the skill connects it with domain_verbinden: DNS records, TXT proof _albatros, and checks until the site appears with a lock in the browser. Use this skill for “custom domain,” “my address,” “buy .ch,” “which domain is available,” “search for a domain,” “DNS,” “A record,” “CNAME,” “TXT record,” “domain doesn’t point to my site,” “certificate,” and “https isn’t working.”
Group a scope of Issues into Waves that can be implemented concurrently without stepping on each other — estimate what each Issue touches, exclude the ones that need a human, and print launch lines. Use when the user has several prepared Issues and wants to know which can run in parallel unattended
Explains Git to someone with no prior knowledge using the analogy of a logbook aboard a ship and its copy in the harbor (Albatros's Git service, code.aufwind.sh). Gets the repo from the harbor, guides them through their first entries (Commit) with good notes, sends them to the harbor (Push), and checks that the copy arrives on the Albatros server at ~/projekt. Rules: main only, stage only your own files individually, never force-push. Use this skill for “Git,” “GitHub,” “harbor,” “commit,” “push,” “pull,” “Repo,” “what is a repository,” “save my changes,” “push rejected,” and “conflict,” and before committing anything for the person.
Explain how a resource or subsystem works, its runtime flow across client, server and NUI, and where things live, through read-only subagents. Use when the user asks how something works, where code should live or which layer owns it, or when a skill such as architect calls for it
Helps someone with no prior knowledge write and choose text and images for their website: a homepage in three sentences, short text for people reading on mobile, their own photos instead of stock images, image rights and image size, and making AI text sound like their own voice. The result is a content list in docs/inhalte.md and the text on the site. Use this skill for “writing text,” “what should I write on the homepage,” “About us,” “images for the website,” “may I use this image,” “text sounds like AI,” and “content.”
Install and configure a PostHog SDK in a repository you can read and edit, following PostHog's docs for the framework. Use when a user working in their codebase asks to add, install, or set up PostHog, product analytics, session replay, or a PostHog SDK. Covers finding the right docs page, installing the latest package, getting the project token and ingestion host from project-get, keeping them in the env file, server-side setup, identifying users, and verifying the change. If you can't access the user's code, as is common in ChatGPT on the web or Claude on the web, use installing-posthog-from-chat instead.
Plans and guides a project's move from Albatros to its own server, explaining it with the analogy of moving into your own house: a moving checklist; renting and setting up a server (SSH with keys only, firewall, updates, Caddy for HTTPS); taking the Logbuch on GitHub along; switching Fliessband there to the new destination over SSH with your own key; bringing data and secrets; testing; changing the address in DNS, or transferring a domain bought through Albatros to a new registrar with the auth code from domain_mitnehmen; and handling backups yourself. Use this skill for “own server,” “move,” “away from Albatros,” “Hetzner,” “VPS,” “self-host,” “landing,” and “what do I need for my own server.”
Hauptskill von Albatros: der Fluglotse. Fragt mit dem Werkzeug lage den echten Stand der Person ab (Abo, Schlüssel, Server oder Seite, Fliessband, Domain, Mission) und folgt dann genau dem Skill, der jetzt dran ist; nach jedem geschafften Schritt fragt er neu. Ohne Anmeldung zeigt er die offene Bibliothek aller Skills zum Selbstwählen und erklärt, wie die Anmeldung geht. Nutze den Skill, sobald jemand an seinem Albatros-Projekt weiterarbeitet oder fragt «was jetzt?», «wie weiter?», «was ist der nächste Schritt?», «wo stehe ich?», «es geht nicht», «es klemmt», «ich weiss nicht weiter», bei /albatros:lotse und am Ende des Skills start. Bei einer klaren Frage zu einem Thema (z. B. «wie verbinde ich meine Domain?», «was ist ein SSH-Schlüssel?») hat der passende Fach-Skill Vorrang.
Delete the comments in a diff that the code should make unnecessary, through a fresh read-only reviewer, then fix the code each deleted workaround comment was excusing. Use before a change goes to review, or when the user asks to strip comments from a diff.
Use when posing, animating, or explaining a 3D human skeleton/manikin: anatomical joints, ROM clamps, walk/run/dance/backflip sequences, Three.js viewer, or agent-driven WebMCP figure control (reach/look_at). Phrases like pose the manikin, skeleton scheme, animate a walk cycle. Not for general 3D scenes, physics/ragdoll, IK foot-locking, or mocap import.
Erklärt CI/CD einer Person ohne Vorwissen mit dem Bild vom Fliessband mit Qualitätskontrolle und richtet es ein: Ein Workflow im Hafen von Albatros (Forgejo, code.aufwind.sh) startet bei jedem Push auf main. Der Arbeiter (Runner) auf dem eigenen Server baut die Seite, liefert sie mit Gesundheitscheck aus, prüft sie über die öffentliche Adresse und springt sonst auf die letzte gute Version zurück. Nutze den Skill bei «Pipeline», «CI/CD», «GitHub Actions», «Forgejo Actions», «Workflow», «Runner», «automatisch ausliefern», «deployen», «wie kommt meine Änderung auf den Server», «Fliessband ist rot», «Deploy fehlgeschlagen».
Helps bring a small Swiss website into legal compliance, explaining it to people with no prior knowledge using the analogy of a doorbell nameplate and house rules: legal notice (UWG Art. 3 Abs. 1 lit. s), privacy policy under revDSG (information duty Art. 19), cookies (Art. 45c FMG), when the EU GDPR also applies, image rights, and marketing emails only with consent. Not legal advice. Use this skill for “legal notice,” “privacy,” “privacy policy,” “DSG,” “DSGVO,” “cookie banner,” “do I legally need this,” “what must go on my website,” and “contact form privacy.”
Helps a small website become easier to find in search engines, explaining it to people with no prior knowledge using the analogy of signposts and a city map. Covers page titles and descriptions, a main heading, descriptive URLs, image descriptions, loading time, sitemap.xml, robots.txt, structured data for local businesses, Google Search Console and Business Profile. Use this skill for “SEO,” “get found on Google,” “Google can’t find my site,” “search engine,” “Sitemap,” “meta description,” “get found locally,” and “Google Maps listing.”
Rundgang durch den eigenen Albatros-Server für eine Person ohne Vorwissen. Erklärt Terminal, Ordner, Speicher, Arbeitsspeicher, laufende Programme und den Hauptschlüssel sudo mit Bildern aus einer Wohnung. Die Person tippt die ersten Befehle selbst. Nutze den Skill bei «was ist auf meinem Server», «wie bewege ich mich im Terminal», «was ist ein Ordner auf dem Server», «ls cd pwd», «wie viel Platz habe ich», «was läuft da», und nach dem ersten erfolgreichen SSH-Besuch.
Configure the Overextended skills. Picks which model and reasoning level each subagent role uses within a budget you choose, then detects your FiveM server, its ox resources and framework. Writes `~/.config/ox/models.md` and `.ox/config.md`, which the other ox skills read.
Erklärt einer Person ohne Vorwissen den SSH-Schlüssel mit dem Bild von Hausschlüssel und Schloss, erzeugt das Schlüsselpaar lokal auf ihrem Computer, hinterlegt nur den öffentlichen Teil bei Albatros und testet den ersten Besuch auf dem Server. Nutze den Skill bei «SSH-Schlüssel», «ssh-keygen», «ich komme nicht auf meinen Server», «Permission denied (publickey)», «was ist ein public key», «neuer Computer», und als Schritt 4 von /albatros:start.
Gets Albatros started for someone with no technical background. Asks whether they want a website or a shop, guides them through signing up in the browser, choosing a plan (Free for learning, Light for a website from the Logbuch, Pilot with their own server), and setting up an SSH key and a site or server until the first page is live at name.aufwind.sh. Use this skill for /albatros:start, “start Albatros,” “I want a website,” “I have a business idea,” “how do I get started,” “I’m new here,” “do I need a server,” “how much does Albatros cost,” and when someone mentions Albatros but has no account or site yet.
Sets up privacy-friendly website analytics with PostHog alongside someone with no prior knowledge. First, create a small event plan (which actions to count, and exactly when), then install it, set up a goal event such as “inquiry sent,” filter out your own visits, and compare the results with actual inquiries. Use this skill for “analytics,” “count visitors,” “how many people visit my site,” “PostHog,” “Google Analytics,” “tracking,” “conversion,” “measure an event,” and “where do my visitors come from.”
Video editing skill: edit a talking-head video (YouTube video, course lesson, product demo, podcast on camera, vlog) the way an editor would. Transcribes with word timestamps (free local faster-whisper, your own Groq or OpenAI key, or an existing SRT/VTT), removes silences, "um"s and "uh"s, stutters and retakes (keeps the last take), adds jump-cut punch-ins, cleans and levels the audio, writes an SRT caption file and YouTube chapters, optionally burns captions or makes a vertical version, shows a cut list to approve before rendering, then posts to YouTube and other platforms with WoopSocial after you say yes. Works on Mac, Windows and Linux with ffmpeg and Pillow; no paid API required. Use when someone says "edit my video," "remove silences," "cut the ums," "remove filler words," "jump cut my video," "clean up this recording," "edit this talking head video," or "video editing with Claude Code." Never cuts what the user marked to keep, confirms before anything posts. Standalone: needs no other skills.
Plant mit einer Person ohne Vorwissen ihre Webseite, bevor gebaut wird: für wen, was Besucher tun sollen, welche Seiten es braucht, welche Inhalte schon da sind, welche Vorbilder gefallen. Ergebnis ist ein Grundriss in docs/plan.md. Nutze den Skill bei «ich will eine Webseite», «Webseite planen», «was brauche ich für eine Webseite», «welche Seiten», «Sitemap», «wo fange ich an», und immer bevor auf dem Weg Webseite die erste Seite gebaut wird.
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.
