inference-workflowsA skill your agent uses when running RobustVideoMatting inference, loading weights, using convertvideo or TorchHub, converting image/video inputs, or reasoning about exported model runtimes.
Inference Workflows is an agent skill from VectorSpaceLab/AREX-Skill. Use when running RobustVideoMatting inference, loading weights, using convertvideo or TorchHub, converting image/video inputs, or reasoning about exported model runtimes.
Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including scripts and reference files (for example `references/converter-reference.md`, `references/model-loading.md` and `references/troubleshooting.md`).
It sits in AI & LLM Engineering. It works with PyTorch. The repository describes itself as: A Skill Library for Automated Machine Learning. The licence is GPL-3.0.
5 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit ac3fe1a. It shows what the files ask for, not the result of running them.
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.
Ships 1 file in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
pythonFrom the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Inference Workflows loads about 1.2k tokens when it runs, and up to ~4.5k if it reads all its reference files. Until then it costs about 48 tokens; SKILL.md has 429 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.
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); the scripts in this folder are not scanned.

permits. The converter still recycles recurrent states across chunks.A good answer names the selected runtime, exact converter arguments or CLI flags, required input/output paths, checkpoint/device handling, validation steps, and likely failure modes. It should not require future agents to open the original repository docs or scripts.

A skill your agent uses when running RobustVideoMatting inference, loading weights, using convertvideo or TorchHub, converting image/video inputs, or reasoning about exported model runtimes. Inference Workflows is an agent skill from VectorSpaceLab/AREX-Skill. Use when running RobustVideoMatting inference, loading weights, using convertvideo or TorchHub, converting image/video inputs, or reasoning about exported model runtimes.
Inference Workflows fits situations like: running RobustVideoMatting inference; loading weights; using convertvideo; converting image/video inputs.
Run `npx skills add VectorSpaceLab/AREX-Skill --skill inference-workflows -a claude-code`. Or copy the skill folder (skills/repositories/repo-skills/robust-video-matting/sub-skills/inference-workflows in VectorSpaceLab/AREX-Skill) into .claude/skills/inference-workflows in your project. Claude Code loads it when a task matches its description.
Run `npx skills add VectorSpaceLab/AREX-Skill --skill inference-workflows -a codex`. Or copy the skill folder (skills/repositories/repo-skills/robust-video-matting/sub-skills/inference-workflows in VectorSpaceLab/AREX-Skill) into .agents/skills/inference-workflows in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add VectorSpaceLab/AREX-Skill --skill inference-workflows -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/inference-workflows, .gemini/skills/inference-workflows, .github/skills/inference-workflows and .opencode/skills/inference-workflows in your project.
Going by SKILL.md and its folder, Inference Workflows needs Python for the scripts in its folder and the command-line tools its instructions call (python). Our summary lists: Python 3.
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.
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. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.
Inference Workflows is published under the GPL-3.0 licence (declared in SKILL.md). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.2k tokens (SKILL.md is roughly 4.9k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 3.3k tokens, read only when the agent opens those files.
