I4h Lerobot Viz

What it does

When your agent uses it

• Videos and state/action timelines
• Do not use for raw workflow HDF5
• Incomplete conversion output

Example prompts

• “/i4h-lerobot-viz”

Workflow steps

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

1. 1Resolve the base checkout and one completed LeRobot dataset.
2. 2Launch its managed local server.
3. 3Open the printed URL.
4. 4Inspect videos, timelines, episode count, and cleanup state.

What it can do on your machine

Read from SKILL.md and the folder at commit 14a98ae. 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

  Shell commands in SKILL.md call:

  • git

  From the folder's file list and the shell code blocks in SKILL.md.

• Network

  Hosts in commands or code, which the agent is likely to contact:

  • github.com

  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

I4h Lerobot Viz loads about 976 tokens when it runs. Until then it costs about 49 tokens; SKILL.md has 327 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~49

When it runs · the whole SKILL.md, loaded when a task matches

~976

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

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.
