Three.js Awesome Graphics Agent Skills packages reusable implementations for cameras, procedural materials and geometry, water, weather, volumetrics, post-processing, and visual validation. Rather than acting as an API cheat sheet, it gives coding agents concrete patterns and example assets for building sophisticated scenes and games. The pack installs through npm into supported hosts including Codex, Claude Code, and Cursor.

This collection gives coding agents 66 game-development skills plus a router that detects the project engine and the task being requested. Users describe a feature in plain language, and the router loads the relevant engine, discipline, genre, and shipping guidance in sequence. It covers Godot, Unity, Unreal, several web engines, Bevy, pygame, LÖVE, and Roblox, using portable SKILL.md folders written from primary documentation and pinned to stated engine versions.

DSPy Agent Skills helps Claude Code, Codex, and compatible agents build, evaluate, and optimize DSPy programs, from core modules and evaluation to GEPA, RLM, and end-to-end workflows. The pack is validated against the DSPy 3.2.x API and includes runnable examples with offline dry-run modes. Python 3.10 or newer is required, while Deno is needed only for the RLM examples.

Startup Founder Skills packages common company-building tasks into agent workflows for pitch decks, investor research, outreach, product requirements, recruiting, engineering reviews, legal operations, finance, and marketing. A shared startup-context skill supplies the company's stage, product, market, team, metrics, and goals so each task can produce output tailored to the same business.

Create paper figures through two distinct workflows: image generation for architectures, schematics, and graphical abstracts, and local plotting for benchmarks, ablations, heatmaps, or any panel where values must remain exact. The skill includes bilingual figure briefs, scripts, and editable handoff formats. Conceptual image generation requires a supported provider such as OpenAI or Gemini-compatible services.

Give the Claude Code skill a short-film idea and it structures the theme, scene, atmosphere, camera rules, and storyboard into a model-ready prompt. It includes genre templates, failure-to-fix examples, and a browser-based prompt library for Sora, Kling, Veo, Seedance, and similar tools. Some original Mx-Shell materials are educational references and require separate permission for commercial use.

VibeTree gives each AI-assisted task its own Git worktree so several features or fixes can progress in parallel with separate terminal state. Desktop, browser, and mobile access are available, but the main branch is still developing cloud and broader platform capabilities; the README recommends release-v0.1 for a stable desktop-only build.

Spine Animation AI helps Claude turn separated character images and a reference pose into Spine 2D skeletal animation assets. It can position parts with image matching, build skeleton JSON and draw order, generate common motions such as idle or walk, and create interactive HTML5 previews. It can also refine an existing Spine skeleton, but users still need well-prepared artwork and a specific animation goal.

JetBrains/skills collects 129 agent skills from 15 upstream repositories into a flat catalog that is easier to browse and reuse. Each skill preserves its original source link, while included CI can scan changed skills or audit the full repository. The collection is intended for demonstration and education, so critical workflows should still be tested independently.

Commit is a lightweight macOS Git client built around a command-palette workflow. Invoke it with a keyboard shortcut, enter a commit message, and it automatically detects the repository you have been working in before creating the commit. It can also push the result when requested, keeping routine changes out of a full Git GUI. Current downloads are provided for Apple Silicon and Intel Macs. Windows and Linux are referenced only as future issue requests rather than supported releases.

WhatsApp Backup Reader opens exported chat ZIP files in a browser or desktop app, making messages, photos, videos, and voice notes searchable without uploading them. Users can bookmark messages, inspect conversation statistics, browse a dated media gallery, and export selected files. Voice notes are transcribed locally with Whisper, with no account, server, or API key required. The transcription workflow depends on a WebGPU-capable environment.

This collection gives compatible AI agents a staged workflow for film and television development, from screening source novels to analyzing plot structure, evaluating adaptation potential, planning vertical dramas, and drafting scripts. Its 31 skills are separated by creative task, while orchestration skills can split long text, coordinate analysis, and combine results. The package covers short-form vertical series, longer dramas, television, and film, but it is an instruction library for writing and evaluation rather than a video production application.

Orkas is a local-first desktop application where a Commander turns a goal into an executable path and coordinates specialist agents in parallel or sequence. From one chat, users can combine research, writing, file analysis, automation, coding, video, or slide work and hand tasks to local tools such as Claude Code or Codex. Conversations, files, agent definitions, and API keys remain on disk, while model calls go directly to the provider you choose. Cloud access is only necessary for cloud models; a local endpoint can keep the workflow offline.

PrismOS-AI is a local-first desktop assistant that uses Ollama models to work with conversations, images, and office documents while storing knowledge across sessions. Several specialized agents can debate a request before writing the result into its persistent graph, with desktop surfaces for retrieval, global access, and patterns in past interactions. It runs on Windows, macOS, and Linux, but the full experience depends on suitable hardware and locally available models.

Exam Cram Coach organizes slides, notes, assignments, and past papers into a chaptered knowledge base and provenance-labeled quiz bank. It adapts tutoring, drills, mistake review, and cheat-sheet preparation to the learner's starting point and available time, while marking material-backed claims, AI supplements, and unsupported questions separately. Basic text and Office ingestion uses standard tooling, but some PDF and visual artifact routes require optional local dependencies.

Neel helps Nim developers create desktop tools with a web frontend while retaining access to Nim on the backend. It handles routing, JSON conversion, and two-way calls between JavaScript and Nim, and release builds can embed the frontend assets. The library has been tested on macOS, Windows, and Linux, but it currently opens Chrome in app mode by default and is described as too early for large commercial applications.

Transcribe meetings, courses, streams, podcasts, or other audio playing on your computer through multiple cloud providers or a local whisper.cpp service. DeLive adds floating captions, searchable local history, transcript correction, chat, briefings, and mind maps in a cross-platform desktop app; its local REST API, WebSocket interface, and MCP server are disabled by default and can be enabled with optional authentication.

NSFC Agent Skills offers four independent skills for structuring a proposal, creating research figures and roadmaps, managing literature and citations, and checking current funding policies. Researchers can load only the relevant skill in OpenClaw or another Agent Skills-compatible tool for each stage of the application. The collection is advisory: users must verify all generated material, follow research-integrity requirements, and defer to the official NSFC guidance for the applicable year.
