What it does

Ghstack CI is an agent skill from pytorch/pytorch. Manage CI for PyTorch ghstack stacks by running CI where its results are useful now and deferring other PRs with [no-ci]. Use when creating, submitting, updating, restacking, or landing a stack of PRs.

Its SKILL.md is about 1.4k 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 AI & LLM Engineering, covering Deep learning. It works with PyTorch. The repository describes itself as: Tensors and Dynamic neural networks in Python with strong GPU acceleration.

When your agent uses it

  • Landing a stack of PRs
  • Tasks that involve Deep learning

Example prompts

  • “/ghstack-ci”

Workflow steps

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

  1. Identify the full stack in dependency order, from bottom to top, including
  2. Choose PRs whose results are useful now. Prefix the other titles with
  3. Before creating new PRs with ghstack, put the prefix in the commit
  4. For existing PRs, add or remove the prefix in both the live PR title

What it can do on your machine

Read from SKILL.md and the folder at commit 84af535. 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:

    • gh

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

  • Network

    No URLs in SKILL.md. Its commands use gh, 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

Ghstack CI loads about 1.4k tokens when it runs. Until then it costs about 53 tokens; SKILL.md has 815 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~53
When it runs · the whole SKILL.md, loaded when a task matches
~1.4k

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 815 words (~1,429 tokens).

“Keep CI usage low by running it where the results can guide the current work. Explicitly mark deferred PRs with the [no-ci] title prefix, and remove it when their results become useful. Follow explicit user CI preferences.”

Run `npx skills add pytorch/pytorch --skill ghstack-ci -a codex`. Or copy the skill folder (.agents/skills/ghstack-ci in pytorch/pytorch) into .agents/skills/ghstack-ci in your project. Codex loads it when a task matches its description.

Can I use Ghstack CI 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 pytorch/pytorch --skill ghstack-ci -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/ghstack-ci, .gemini/skills/ghstack-ci, .github/skills/ghstack-ci and .opencode/skills/ghstack-ci in your project.

What does Ghstack CI need to run?

Going by SKILL.md and its folder, Ghstack CI needs the command-line tools its instructions call (gh).

Does Ghstack CI access the network?

SKILL.md contains no URLs. Its commands use gh, which can reach the network depending on how they are called. This is read from the text; nothing was executed.

Is Ghstack CI 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. Review the folder before installing.

What licence does Ghstack CI use?

Ghstack CI has a licence file (the repository's licence) that doesn't match a standard licence. Read it on GitHub before reusing the skill.

How many tokens does Ghstack CI use?

About 1.4k tokens (SKILL.md is roughly 5.7k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
