check / check (push) Successful in 2m41s
script/fmt now runs go fmt and then prettier --write on every Markdown file; script/fmt-check runs the gofmt check and then prettier --check. prettier is pinned in package.json and yarn.lock and configured in .prettierrc with four-space indents and prose wrapped at 80 columns, all copied from the sneak/prompts templates. After Go and the Go modules, script/bootstrap uses an installed node or else a pinned one through a hash-verified nvm archive, then an installed yarn or else a pinned one, then the yarn dependencies. README.md is reformatted by make fmt, and its Entrypoints section says what fmt, fmt-check and bootstrap now do. Model: opus-5-5

# script/bootstrap: install everything needed to build and develop this
|
|
# repo. Idempotent: every install is guarded by a check, so tools that
|
|
# are already there are left alone. Base tooling comes from nix, apt,
|
|
# brew, or apk, detected in that order, and nothing is assumed to be
|
|
# present. Go is installed at the version the Dockerfile's Go image
|
|
# carries, from the official release archive, into ~/.local/go. Node is
|
|
# used directly if installed; otherwise it is installed at a pinned
|
|
# version via nvm (installing nvm itself first, from a hash-verified
|
|
# release archive, never curl | sh). The linter is not installed here:
|
|
# linting and testing run only as phases of the Dockerfile, so Docker is
|
|
# what is needed for them, and that is checked for rather than
|
|
# installed.
