What it does
GPU Vis Modes is an agent skill from ad-repo/nullplayer. Per-mode shader and algorithm internals for the GPU visualization modes shared by both the main window and spectrum window — Fire, JWST, Lightning, Matrix, Snow, EKG. Includes Metal pass counts, audio mappings, color schemes, intensity presets, and the shader file names. Use when editing a specific mode's shader or audio response.
Its SKILL.md is about 1.8k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
The repository describes itself as: nullPlayer is a free open source macOS media player with some unique features.
When your agent uses it
- Editing a specific modes shader
Example prompts
- “/gpu-vis-modes”
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- compute propagate_fire (128×96 grid)
- render flame_blur_h (horizontal blur, fire grid → r16Float intermediate texture at drawable size)
- render flame_blur_v (vertical blur + color mapping → drawable)
What it can do on your machine
Read from SKILL.md and the folder at commit 04582d1. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
GPU Vis Modes loads about 1.8k tokens when it runs. Until then it costs about 87 tokens; SKILL.md has 855 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 855 words (~1,820 tokens).
“Internals of the shader modes shared between main-window-visualization and spectrum-analyzer-window. See metal-gotchas for cross-cutting Metal pitfalls.”

Questions about GPU Vis Modes
What does GPU Vis Modes do?
Per-mode shader and algorithm internals for the GPU visualization modes shared by both the main window and spectrum window — Fire, JWST, Lightning, Matrix, Snow, EKG. GPU Vis Modes is an agent skill from ad-repo/nullplayer. Per-mode shader and algorithm internals for the GPU visualization modes shared by both the main window and spectrum window — Fire, JWST, Lightning, Matrix, Snow, EKG.
When should I use GPU Vis Modes?
GPU Vis Modes fits situations like: editing a specific modes shader.
How do I install GPU Vis Modes in Claude Code?
Run `npx skills add ad-repo/nullplayer --skill gpu-vis-modes -a claude-code`. Or copy the skill folder (skills/gpu-vis-modes in ad-repo/nullplayer) into .claude/skills/gpu-vis-modes in your project. Claude Code loads it when a task matches its description.
How do I install GPU Vis Modes in Codex?
Run `npx skills add ad-repo/nullplayer --skill gpu-vis-modes -a codex`. Or copy the skill folder (skills/gpu-vis-modes in ad-repo/nullplayer) into .agents/skills/gpu-vis-modes in your project. Codex loads it when a task matches its description.
Can I use GPU Vis Modes in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add ad-repo/nullplayer --skill gpu-vis-modes -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/gpu-vis-modes, .gemini/skills/gpu-vis-modes, .github/skills/gpu-vis-modes and .opencode/skills/gpu-vis-modes in your project.
What does GPU Vis Modes need to run?
SKILL.md names no scripts, command-line tools or credentials: GPU Vis Modes is instructions for the agent only.
Does GPU Vis Modes access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is GPU Vis Modes safe to install?

What licence does GPU Vis Modes use?
GPU Vis Modes has a licence file (the repository's licence) that doesn't match a standard licence. Read it on GitHub before reusing the skill.
How many tokens does GPU Vis Modes use?
About 1.8k tokens (SKILL.md is roughly 7.3k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
