What it does
Cue Sheets is an agent skill from ad-repo/nullplayer. .cue sheet support — direct-play virtual split (open a .cue or an audio file with a sibling .cue → N playlist rows from one backing file, gapless) and library physical split-on-import (ffmpeg per-track files, off by default). Use when working on cue parsing, the AudioEngine cue boundary detector, in-file offset playback, or CueAlbumSplitter.
Its SKILL.md is about 2.6k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Media & Creative, covering Video production and iOS development. It works with FFmpeg. The repository describes itself as: nullPlayer is a free open source macOS media player with some unique features.
When your agent uses it
- Working on cue parsing
- The AudioEngine cue boundary detector
- In-file offset playback
- CueAlbumSplitter
Example prompts
- “/cue-sheets”
Workflow steps
6 steps, taken from the first numbered list in SKILL.md.

- Per-album subdirectory: outputs go into // — named from the source file's own ALBUM/ARTIST tags read via ffprobe (sourceTags), falling…
- Output is always re-encoded FLAC (-c:a flac, not -c copy — copy isn't sample-accurate at cut points) for both lossless and lossy sources…

What it can do on your machine
Read from SKILL.md and the folder at commit 3d87ce1. 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
Cue Sheets loads about 2.6k tokens when it runs. Until then it costs about 89 tokens; SKILL.md has 1,234 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 1,234 words (~2,650 tokens).
“Two independent code paths that consume .cue sheets. The Stream Ripper writes cues (one TRACK per chapter — see the stream-ripper skill); this feature reads them.”

When should I use Cue Sheets?
Cue Sheets fits situations like: working on cue parsing; the AudioEngine cue boundary detector; in-file offset playback; cueAlbumSplitter.
How do I install Cue Sheets in Claude Code?
Run `npx skills add ad-repo/nullplayer --skill cue-sheets -a claude-code`. Or copy the skill folder (skills/cue-sheets in ad-repo/nullplayer) into .claude/skills/cue-sheets in your project. Claude Code loads it when a task matches its description.
How do I install Cue Sheets in Codex?
Run `npx skills add ad-repo/nullplayer --skill cue-sheets -a codex`. Or copy the skill folder (skills/cue-sheets in ad-repo/nullplayer) into .agents/skills/cue-sheets in your project. Codex loads it when a task matches its description.
Can I use Cue Sheets 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 cue-sheets -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/cue-sheets, .gemini/skills/cue-sheets, .github/skills/cue-sheets and .opencode/skills/cue-sheets in your project.
What does Cue Sheets need to run?
SKILL.md names no scripts, command-line tools or credentials: Cue Sheets is instructions for the agent only.
Does Cue Sheets 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 Cue Sheets safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
What licence does Cue Sheets use?
Cue Sheets 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 Cue Sheets use?
About 2.6k tokens (SKILL.md is roughly 11k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
What are the alternatives to Cue Sheets?
Skills that share tags, products or a category with Cue Sheets: Video Understand (calesthio/OpenMontage, 66k stars), HyperFrames Video Entry Point (heygen-com/hyperframes, 60k stars), Video Shots (eternityspring/reelbench-skills, 878 stars) and Mobile Demo Film Editor (superset-sh/superset, 15k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
