What it does
Ckpt is an agent skill from cua-lite/cua-lite. Manage training checkpoints — export from the slime container to the host .ckpts/ directory with a runinfo.txt for full reproducibility.
Its SKILL.md is about 800 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 Research & Science, covering Reproducible research. The repository describes itself as: CUA-Lite: An Open Platform for Computer-Use Agents.
When your agent uses it
- Tasks that involve Reproducible research
Example prompts
- “/ckpt”
Requirements
- Docker
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Identify the checkpoint in the container
- Get the eval timestamp for the checkpoint iter from training logs.
- Copy checkpoint from container to host
- Write run_info.txt in the hf/ directory (one level above iter dirs — shared across all iters of the same run). Must contain all…
What it can do on your machine
Read from SKILL.md and the folder at commit 65a61c4. 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:
docker
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use docker, which can reach the network depending on how they are called.
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
Ckpt loads about 800 tokens when it runs. Until then it costs about 36 tokens; SKILL.md has 221 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
Without a licence we can't republish the file, so here is its outline and opening line. It has 221 words (~800 tokens).
“Checkpoint operations. $ARGUMENTS starts with a subcommand.”

- ckpt
Files

Questions about Ckpt
What does Ckpt do?
Manage training checkpoints — export from the slime container to the host .ckpts/ directory with a runinfo.txt for full reproducibility. Ckpt is an agent skill from cua-lite/cua-lite.txt for full reproducibility.
When should I use Ckpt?
Ckpt fits situations like: tasks that involve Reproducible research.
How do I install Ckpt in Claude Code?
Run `npx skills add cua-lite/cua-lite --skill ckpt -a claude-code`. Or copy the skill folder (.claude/skills/ckpt in cua-lite/cua-lite) into .claude/skills/ckpt in your project. Claude Code loads it when a task matches its description.
How do I install Ckpt in Codex?
Run `npx skills add cua-lite/cua-lite --skill ckpt -a codex`. Or copy the skill folder (.claude/skills/ckpt in cua-lite/cua-lite) into .agents/skills/ckpt in your project. Codex loads it when a task matches its description.
Can I use Ckpt 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 cua-lite/cua-lite --skill ckpt -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/ckpt, .gemini/skills/ckpt, .github/skills/ckpt and .opencode/skills/ckpt in your project.
What does Ckpt need to run?
Going by SKILL.md and its folder, Ckpt needs the command-line tools its instructions call (docker). Our summary lists: Docker.
Does Ckpt access the network?
SKILL.md contains no URLs. Its commands use docker, which can reach the network depending on how they are called. This is read from the text; nothing was executed.
