Use after a completed customer, prospect, partner, or important internal sales call, discovery session, demo, or conversation, including when the user supplies or uploads a transcript, notes, recording summary, or other grounded evidence. Advise on, assess, qualify, recap, and produce seller-ready follow-up actions and drafts.
Author or modify a 3D CAD part for Forgent3D with one CLI, cad-build. Two routes, picked from the request and the files present — a parametric model.py in the build123d dialect, built on the bundled wasm kernel, measured (cad-build rebuild / check), rendered (snapshot), exported to STEP/STL/GLB and published as a shareable 3D link (preview); or an OpenSCAD .scad, rendered by the bundled OpenSCAD (rebuild reads bbox, volume and echo()), snapshotted, its Customizer parameters walked (knobs), exported to STL/3MF, and handed off as a link that carries the code and converts it to STEP. Use whenever the task is creating or changing a 3D CAD part or assembly, previewing or converting a .scad, or a model.py in the build123d dialect or a .scad file is present.
Get AI-generated videos ready to post, without touching a single slider. Upload your text prompts (MP4, MOV, WebM, GIF, up to 500MB), say something like "generate a 30-second video from my script about a new app feature", and download 1080p MP4 when it's done. Built for content creators who move fast and want to create videos from text without expensive software or filming.
Interacts with the FreeAgent accounting API to manage invoices, contacts, projects, expenses, timeslips, and other financial data. Use when the user needs to retrieve, create, update, or analyze FreeAgent accounting information via the API. All write operations (POST/PUT/DELETE) require explicit user confirmation before execution and default to sandbox unless production is explicitly requested.
Manage freelance and client work professionally — proposals, contracts, scope management, invoicing, and client communication. Covers the business side of creative work. Triggers on freelance, client work, proposals, contracts, pricing, or project scope requests.
Find fresh freelance and contract opportunities across multiple platforms for any skill set. Use this skill when a user asks "find me freelance React jobs", "Upwork gigs for Python developers", "freelance work posted this week", "contract jobs for designers", "find me remote freelance opportunities for [skill]", "I'm looking for freelance work", "what freelance gigs are available for [skill]", or any request to find paid freelance or contract work online.
Frontend (including Electron desktop) performance optimization knowledge base, covering version-specific optimization knowledge for React 16-19, Angular 9-18+, and Electron 12-28+. Works together with the perf-workflow skill: perf-workflow drives the analysis process while this skill supplies frontend-specific quantitative standards, version-aware optimization strategies, bottleneck patterns, and tool references. Use when analyzing performance issues in Web frontend (React/Angular/Vue) or Electron desktop apps. Triggers — 「前端性能」「前端性能优化」「Electron 性能」 / frontend performance, frontend perf optimization, Electron performance.
Use when the user wants to define, parse, or manage a GA4 event taxonomy (이벤트 정의서) — turning a spreadsheet of planned events/parameters into taxonomy.json/taxonomy.md, comparing planned events against what GA4 actually collects, or drafting an initial taxonomy from live GA4 data. Consumes .ga4/config.json + token.json from the ga-auth skill for the live features.
Game design consulting based on Richard Rouse III's Game Design Theory and Practice. Use when helping with game design decisions, player psychology, gameplay systems, storytelling, playtesting, or evaluating fun. Provides frameworks for understanding what players want, creating engaging gameplay mechanics, balancing challenge and fun, non-linear design, in-game storytelling, and effective playtesting practices. NOT for coding or programming - focused on design philosophy and player experience.
Overall methodology for penetration testing GCP cloud environments. Use when the target uses Google Cloud Platform, when GCP-related assets are discovered (GCS Bucket/Compute Engine/Cloud Functions/GKE), when GCP credentials are obtained (Service Account Key/OAuth Token/Metadata Token), or when a security assessment of a GCP environment is required. Provides a full decision tree from unauthenticated enumeration to privilege escalation, post-exploitation, and GCP-to-Workspace traversal. Covers the attack surface of 37+ GCP services
GCSE Chemistry tutor and revision assistant for 15–16 year old students preparing for 2026 exams across AQA, Edexcel, OCR, and WJEC boards. Use when a student asks for help understanding chemistry topics, answering exam questions, revising for GCSEs, practising required practicals, or wants guidance on exam technique for GCSE Chemistry.
Generate AI images using ByteDance's Seedream 4.0 API. Use when user wants to create, generate, or make images from text descriptions, especially for professional graphics, marketing materials, posters, product visualization, or high-quality visual content. Supports 2K/4K resolution, multiple aspect ratios, batch generation, and reference image guidance. Ideal for marketing assets, concept art, social media graphics, and design projects.
Perform complex, long-running research tasks using Gemini Deep Research Agent. Use when asked to research topics requiring multi-source synthesis, competitive analysis, market research, or comprehensive technical investigations that benefit from systematic web search and analysis.
Generate SSH keys per team standards and return the public key. Ed25519 by default, RSA 4096 as fallback (RSA 2048 is never allowed); private keys are chmod 600 and named after the service. Use this skill whenever the user wants an SSH key, keypair, deploy key, or login key for a service or machine, or mentions ssh-keygen/puttygen — e.g. "generate ssh key", "create an ssh keypair", "make a login key for service xxx", "generate a deploy key" — even if they do not mention team standards. Prefers puttygen (.ppk/.pem/.pub); falls back to ssh-keygen.
Remote-control a running GIMP (the open-source image editor) by Python script through its built-in Script-Fu server — build documents and layer stacks, fill, gradient and brush-stroke drawables, add text layers, attach non-destructive GEGL filters, cut out with masks and selections, retouch photos, and export PNG/JPEG/TIFF/GIF/.xcf or batch-convert whole folders in the session the user is looking at. Use whenever the user wants to create or edit a GIMP document (.xcf), composite, retouch or resize a raster image, batch-process a folder of images, script or automate GIMP, export layers separately, or says "GIMP", "xcf", "gimp script", "batch resize these photos", "open this in GIMP" — even if they do not mention scripting. Also covers Hungarian: "csinálj egy képet GIMP-ben", "vezéreld a GIMP-et", "rétegek", "exportáld PNG-be", "kötegelt átméretezés". Not for natural-media painting (use krita or rebelle), vector and layout design (use affinity), or keyframed motion graphics (use cavalry).
Fetch GitHub issues, understand their requirements, plan and implement the solution, then run verification—without committing, pushing, or creating a PR. Works one issue at a time: when several issues are named, or when no issue number is given at all (then it takes every open issue of the current repo as the queue), implement them sequentially so each one lands as its own commit and its own pull request, never bundled together. Use when someone says “work on issue #N”, “do #N”, “implement #N”, “fix issue #N”, “work through the open issues”, “do all the issues”, “dolgozz a #N-es issue-n”, “csináld meg a #12, #13 és #14 issue-kat”, “csináld meg az összes issue-t” or pastes GitHub issue URLs to implement. Not for an unattended run shipping a PR per issue (github-do-all-issues), or for creating, labeling or triaging issues (github-issues), or for committing and opening the PR (github-commit-pr, which runs once per issue afterwards). The user always reviews each issue's result and decides when to commit.
Installs and authenticates the GitHub CLI (gh) in a Claude.ai container, then runs gh commands against it. Use for "install gh", "gh auth", "create an issue or PR from the CLI", "gh is not authenticated", or any GitHub operation you want to issue as a gh command rather than a raw API call. This skill is the transport rather than the analysis. To understand what a repository does or contains, use exploring-codebases; to add a repo to the session, accessing-github-repos.
Systematically diagnose GKE JobSet interruptions, restarts, and preemptions for AI/ML training workloads. Identifies preemption events, maintenance interruptions, bad host VMs, unhealthy pods, and coordinator worker failures.
A tool for creating and managing Garry's Mod addons, including Lua scripting, content creation, and addon packaging. Use when: developing new addons, writing Lua scripts for GMod, organizing addon files, or when user mentions Garry's Mod, GMod, Lua scripting, or addon development.
Builds and troubleshoots Godot 4.x 3D gameplay, including CharacterBody3D controllers, jumping and slopes, third-person cameras, SpringArm3D collision, WorldEnvironment, lights, shadows, and 3D verification. Use when a request mentions 3D movement, camera follow or orbit, environments, lighting, or gameplay feel.
Godot 4.x game development (verified on 4.7) - scaffold, inspect and edit projects, scenes, UI, resources headlessly; author tilesets, ASCII-painted levels, themes, animation, audio buses, custom Resources, collision/navmesh bakes, shaders, export presets; draw pixel art from ASCII, clean generated art, synthesize sound effects and looping music; look up the installed engine's exact API; lint GDScript, scenes and shaders without Godot (Godot 3 renames, un-inferable :=, dead node paths, input actions, res:// paths); catch editor-only node warnings; move files safely; unit-test, smoke-run every scene with input fuzzing, debug, export; verify it all as text (node trees, UI layout, 2D/3D placement, level, image, audio read-backs), no vision or hearing needed. Use when Codex needs to build or fix a Godot game, write or repair .gd/.tscn/.tres/.gdshader files, add art, sound, levels or UI, migrate Godot 3 code, reorganize a project, or validate, test and export.
Provides comprehensive Google Cloud Platform (GCP) guidance including Compute Engine, Cloud Storage, Cloud SQL, BigQuery, GKE (Google Kubernetes Engine), Cloud Functions, Cloud Run, VPC networking, load balancing, IAM, Cloud Build, infrastructure as code (Terraform, Deployment Manager), security configuration, cost optimization, and multi-region deployment. Produces infrastructure code, deployment scripts, configuration guides, and architecture designs. Use when deploying to Google Cloud, designing GCP infrastructure, migrating to GCP, configuring GCE instances, setting up Cloud Storage, managing Cloud SQL databases, working with BigQuery, deploying to GKE, or when users mention "Google Cloud", "GCP", "Compute Engine", "Cloud Storage", "BigQuery", "GKE", "Cloud Run", "Cloud Functions", "VPC", "Cloud SQL", or "Google Cloud Platform".
Search, read, create, update, export, and share files in Google Drive. Use this whenever the user wants to find a file in Drive, read a Google Doc or Sheet, upload a file, move something into a folder, change sharing permissions, or asks "what's in my Drive" — even if they don't say "API". Also use it for any URL under drive.google.com or docs.google.com, or a mention of a Drive file ID. Always start from this skill when interacting with this service — its bundled scripts and recipes are the fastest path.
Apply rigorous survey design principles including construct operationalization, Likert scale development, reliability and validity assessment, and common method variance control. Use this skill when the user designs questionnaires, develops measurement items, needs to evaluate Cronbach's alpha or AVE, or when they ask 'how do I operationalize this construct', 'is my scale reliable', or 'how do I control for CMV'.
Clarify and record user-confirmed UI design requirements through focused question sets, optionally after grill-workflow and before prototype or specification. Use when the user wants custom visual direction, design preferences, or resolution of a design conflict; do not use for product scope or implementation.
Run a one-question-at-a-time research grilling session that sharpens AI research terminology, thesis, hypotheses, experiments, and decisions, then preserves the durable parts as project-owned research docs. Use when the user wants to stress-test a research direction, align vocabulary with an agent, clarify a paper or project thread, scope experiments before committing crew time, or preserve research context, especially for projects run through a Nemo firstmate.
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.
