What it does

Sibling Checkout Commits is an agent skill from JetBrains/intellij-community, published by the product's own GitHub organization. Take commits from a sibling checkout as patches, without a fetch.

Its SKILL.md is about 750 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including scripts (for example `scripts/take-patches.sh`).

It sits in Development. It works with Git. The repository describes itself as: IntelliJ IDEA & IntelliJ Platform.

When your agent uses it

  • Development work in your project

Example prompts

  • “/sibling-checkout-commits”

Requirements

  • A Bash shell

Workflow steps

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

  1. Find the range in the sibling. The base is the last sibling commit this checkout already has; a commit taken
  2. From the root of the receiving checkout run the script. It writes the patches under out/sibling-patches/,
  3. Read the ok lines. Each one names the new commit and confirms that its patch id equals the patch. A DIFF line
  4. On a weekend, the committer date is today: apply the weekend rule of the personal CLAUDE.md to the new commits.

What it can do on your machine

Read from SKILL.md and the folder at commit 06e4175. 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/ (Shell), which the agent can run.

    Shell commands in SKILL.md call:

    • git

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

  • Network

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

Sibling Checkout Commits loads about 753 tokens when it runs. Until then it costs about 23 tokens; SKILL.md has 485 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~23
When it runs · the whole SKILL.md, loaded when a task matches
~753

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.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 485 words (~753 tokens).

“Use this skill when another checkout of the monorepo on this machine holds commits that this checkout needs, for example a reorganization that a new change builds on. The user keeps the checkouts separate, so a clone, a worktree or…”
