Remove signs of AI-generated, translated, or overly mechanical Chinese prose. Use when rewriting, editing, or reviewing Chinese blog posts, essays, newsletters, nonfiction chapters, product analysis, or long-form commentary so they read like native Chinese writing. Trigger this skill when the user asks to 「去 AI 味」, 「润色成中文母语表达」, 「改得像博客或书里写的」, 「减少翻译腔」, or similar. Detect and fix translation-like phrasing, empty big words, formulaic contrast frames, sloganized endings, list inflation, punctuation misuse, terminology/casing inconsistencies, and paragraph rhythm that feels assembled rather than written

Three-layer AI-tone removal: script detection produces a graded report (A mechanical edit / B suggested edit / C report only / X rejected / F fingerprint) + semantic analysis (synonym renaming / chained transitions / colon after conclusions / three-part parallel structures). First, deliver a professional, readable pre-edit report listing this text’s metrics, research significance, original examples, and specific fixes. After the user replies, rewrite according to the allowlist, retest, and generate a before-and-after comparison report (Markdown by default, in the same format as the manuscript). Rules are based on two rounds of testing (629 comparison articles + 270 paired retests on the same topics and facts). For cleaning up completed writing.

Build a live Three.js landscape that stays quiet behind a subject — a noise heightfield on a polar grid so resolution follows the lens, ground coloured by slope and moisture rather than by texture, instanced GPU grass whose wind costs nothing on the CPU, scattered stones, a gradient sky dome, a star field you can actually see, and a time-of-day system that cross-fades instead of cutting. Use for hero backdrops, product stages, scroll worlds, or any scene where a building, object, or figure has to sit in a place rather than float on a gradient.
Duck a music bed under a voice track using Sonilo — automatically lowers the music wherever the voice speaks and lifts it back in the gaps. Use when mixing a separately generated or existing music track under narration, dialogue, or a video's own voice track, without manual volume automation.
Generate AI voiceovers, sound effects, and music using ElevenLabs APIs. Use when creating audio content for videos, podcasts, or games. Triggers include generating voiceovers, narration, dialogue, sound effects from descriptions, background music, soundtrack generation, voice cloning, or any audio synthesis task.
Create publication-quality scientific diagrams using Nano Banana Pro AI with smart iterative refinement. Uses Gemini 3 Pro for quality review. Only regenerates if quality is below threshold for your document type. Specialized in neural network architectures, system diagrams, flowcharts, biological pathways, and complex scientific visualizations
Put weather into a Three.js scene that reads as weather — rain anchored inside the frustum, a storm that is the rain leaned on rather than a second system, lightning on its own light with thunder scheduled by distance, snow that blows up into blizzards and keeps settling until the ground goes white, wet ground with puddles and splashes, and looping ambience that has no seam. Use for scene atmosphere, seasonal states, hero backdrops, or any world where clear/rain/storm/snow needs to be a control the viewer can turn
Use when the user asks for language swap or a task matching the examples below. Translate and dub a video into another language. One worker call preserves each speaker's voice, translates the speech, and returns a fully A/V-synced video. Lipsync ON by default. Use when the user says "translate this video", "dub this in <language>", "make this Spanish/French/Japanese", "translate the audio", or asks for bilingual subtitles on a dubbed/language-swap output. NOT for: subtitles/captions only (use add_captions or video-captions), transcription only (use transcribe_audio directly), or translating on-screen text overlays.
Video and audio processing with FFmpeg. Use for format conversion, resizing, compression, audio extraction, and preparing assets for Remotion. Triggers include converting GIF to MP4, resizing video, extracting audio, compressing files, or any media transformation task.
Redesign GitHub README homepages or create project-native pure SVG, hybrid SVG-composed PNG/WebP, and optional animated GIF assets. Use when a user asks to beautify, redesign, rebrand, visually upgrade, simplify, or audit a GitHub README; create only a hero, section headers, diagrams, badges, motion graphics, showcase modules, or other README assets; or turn a repository homepage into a cohesive visual story. If it’s unclear whether the user wants a whole-README overhaul or assets only, ask which scope they want. For hero assets where pure SVG and generated raster material are both viable, explain the tradeoffs and confirm the implementation before creating the asset.
Generate architecture procedurally in Three.js and film it assembling — a small geometry vocabulary that builds pagodas, castles, domes and spires from parameters instead of mesh files, hip roofs with flying eaves driven by a single profile function, and a clipping-plane build animation where everything below a rising line is finished work and scaffolding stands above it. Use for construction studies, architectural title sequences, procedural landmarks, or any hero object that should build itself rather than fade in
Create, integrate, or audit production-ready rigged 3D characters and monsters with a main model, skeleton, animation library, sockets, collision contracts, separate character equipment, optimized runtime files, catalog media, and an interactive moveset inspector. Use when generating or importing FBX/GLB game actors; defining character-versus-monster asset requirements; separating swords, shields, helmets, armor, or stowed gear; adding idle, walk, run, attack, hit, dodge, block, cast, or death clips; wiring an asset into gameplay; or adding action and equipment controls plus deterministic tests to a game asset catalog
