What it does

Training References is an agent skill from VectorSpaceLab/AREX-Skill. Use when planning or auditing TorchVision reference training/evaluation workflows for classification, quantization, detection, segmentation, video classification, optical flow, similarity learning, or stereo depth without launching expensive jobs.

Its SKILL.md is about 680 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/data-layouts-and-presets.md`, `references/task-command-recipes.md` and `references/troubleshooting.md`).

It sits in AI & LLM Engineering, covering LLM inference and serving. It works with PyTorch. The repository describes itself as: A Skill Library for Automated Machine Learning. The licence is BSD-3-Clause.

When your agent uses it

  • Auditing TorchVision reference training/evaluation workflows for classification
  • Video classification
  • Similarity learning
  • Stereo depth without launching expensive jobs

Example prompts

  • “/training-references”

Requirements

  • Python 3

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. Identify the task family: classification, quantization, detection, segmentation, video classification, optical flow, similarity learning…
  2. Read references/task-command-recipes.md for concrete command skeletons and safety labels.
  3. Check references/data-layouts-and-presets.md for expected dataset layout, preset, and preprocessing assumptions.
  4. Use scripts/inspect_reference_args.py --list or --task to inspect known argument families without importing or running training code.
  5. Read references/troubleshooting.md before advising a user to run any command that needs datasets, GPUs, distributed launch, checkpoints…

What it can do on your machine

Read from SKILL.md and the folder at commit ac3fe1a. 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 1 file in scripts/ (Python), which the agent can run.

    Shell commands in SKILL.md call:

    • python

    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

Training References loads about 684 tokens when it runs, and up to ~4.7k if it reads all its reference files. Until then it costs about 67 tokens; SKILL.md has 259 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~67
When it runs · the whole SKILL.md, loaded when a task matches
~684
With references · SKILL.md plus every file in references/, read only if the agent opens them
~4.7k

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); the scripts in this folder are not scanned.

TorchVision Training References

Use this sub-skill to turn TorchVision's official reference scripts into safe command plans, dataset-layout checks, and troubleshooting notes. The reference scripts are training baselines rather than stable package APIs; always treat generated commands as plans to review before running.

Route first

  • For model constructors, weight enums, or weights.transforms() usage, route to ../models-and-weights/.
  • For transform implementation details, TVTensors, masks, boxes, videos, or custom v2 pipelines, route to ../transforms-and-tv-tensors/.
  • For dataset constructors, downloads, codecs, and tiny fixtures, route to ../datasets-io-utils/.
  • For box utilities, NMS, ROI ops, and detection postprocessing internals, route to ../ops-and-detection/.

Safe workflow

  1. Identify the task family: classification, quantization, detection, segmentation, video classification, optical flow, similarity learning, or stereo depth.
  2. Read references/task-command-recipes.md for concrete command skeletons and safety labels.
  3. Check references/data-layouts-and-presets.md for expected dataset layout, preset, and preprocessing assumptions.
  4. Use scripts/inspect_reference_args.py --list or --task <name> to inspect known argument families without importing or running training code.
  5. Read references/troubleshooting.md before advising a user to run any command that needs datasets, GPUs, distributed launch, checkpoints, or weight downloads.

Safety labels

  • Safe: listing arguments, producing command plans, and reviewing flags.
  • Review required: single-process evaluation on already-prepared local data, especially when it may download weights.
  • Unsafe by default: full training, distributed torchrun, dataset downloads, model-url download checks, release scripts, and benchmarks.

Bundled helper

Run the helper from this sub-skill directory or provide its path explicitly:

bash
python scripts/inspect_reference_args.py --list
python scripts/inspect_reference_args.py --task detection
python scripts/inspect_reference_args.py --task classification --format shell

The helper is a static summary adapted from the reference parsers. It does not import TorchVision, import the original scripts, read datasets, download weights, launch distributed jobs, or run training.

Codex loads it when a task matches its description.

Can I use Training References 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 VectorSpaceLab/AREX-Skill --skill training-references -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/training-references, .gemini/skills/training-references, .github/skills/training-references and .opencode/skills/training-references in your project.

What does Training References need to run?

Going by SKILL.md and its folder, Training References needs Python for the scripts in its folder and the command-line tools its instructions call (python). Our summary lists: Python 3.

Does Training References 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 Training References 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. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.

What licence does Training References use?

Training References is published under the BSD-3-Clause licence (declared in SKILL.md). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does Training References use?

About 684 tokens (SKILL.md is roughly 2.7k 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 4.1k tokens, read only when the agent opens those files.
