What it does
Av Sync Sweep is an agent skill from n1m21n/Infinite. Sweep exported-movie audio/video sync: drift, dropped frames, missing audio, wrong duration, speed/reverse, PDC smear, recorder teardown. Use after touching OutputNode recording, readback, recorder/muxer, decoder, playback speed or PDC, when export sound lags/leads picture, or before a release that ships export.
Its SKILL.md is about 1.9k tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `driver.sh`).
The repository describes itself as: Infinite is a node-based audiovisual workstation — real-time GPU video compositing, procedural 3D geometry, modular synths, DSP, and VST3/AU plugin hosting.
Example prompts
- “/av-sync-sweep”
Requirements
- A Bash shell
What it can do on your machine
Read from SKILL.md and the folder at commit 4e7ffe5. 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
Ships script files (Shell), which the agent can run.
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
Av Sync Sweep loads about 1.9k tokens when it runs. Until then it costs about 82 tokens; SKILL.md has 1,080 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 1,080 words (~1,941 tokens).
“Sweep Infinite's audio/video sync for bugs on both macOS and Windows - exported movies where audio and video drift apart, frames reported but never written to disk, a tone missing from the recorded audio track, wrong movie duration, playback speed…”
