install-creator

A guide for creating installation scripts in a dotfiles repository, which is a repository used to manage personal computer configuration.

In plain words
What is it for?
It helps add scripts under ./install/install-.sh for software installed with Homebrew or built locally, including operating-system-specific behavior.
Why use it?
It helps new install scripts follow the repository's existing rules for package managers, locally built software, operating systems, and file locations.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade F, and why

install-creator scanned grade F with 4 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Asks for rootmediumPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

- `sudo apt install` は linux ブランチ内でのみ使う

Downloads and executes remote codehighSupply chain

curl | sh runs whatever the server returns today, which is not necessarily what it returned when this was reviewed.

- `curl ... | bash` のような公式手順が存在する

Recursive force deletehighDestructive command

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

- 自前ビルドの場合は冒頭で `rm -rf $DOTFILES/pkg/<name>` と `rm -rf $DOTFILES/local/<name>`

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

install-creator is a skill published in the GitHub repository Jxck/dotfiles (95 stars, last pushed 5d ago), with no licence file. It adds 38 tokens to every session and 2,904 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it F with 4 findings (asks for root, downloads and executes remote code, recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
