What this skill does
/printing-press-score Score generated CLIs against the Steinberger bar. Supports rescoring, scoring by name/path, and comparing two CLIs. Quick Start Prerequisites Go 1.26.6 or newer installed cli-printing-press binary on PATH (install with go install github.com/mvanhorn/cli-printing-press/v4/cmd/cli-printing-press@latest) Step 0: Setup Before any other commands, run the setup contract to verify the cli-printing-press binary is on PATH and initialize scope variables: <!-- PRESSSETUPCONTRACTSTART --> <!-- PRESSSETUPCONTRACTEND --> After running the setup contract, capture the PRINTINGPRESSBIN=<abs-path> line from stdout. Every subsequent cli-printing-press ... invocation in this skill must use that absolute path (substitute the value, not the literal $PRINTINGPRESSBIN token) — export PATH above only affects the single Bash tool call it runs in, so later calls open a fresh shell where bare cli-printing-press resolves against the user's default PATH and a stale global can shadow the local build. After capturing the binary path, check binary version compatibility. Read the min-binary-version field from this skill's YAML frontmatter. Run <PRINTINGPRESSBIN> version --json and parse the version from the output. Compare it to min-binary-version using semver rules. If the installed binary is older than the minimum, stop immediately and tell the user: "cli-printing-press binary vX.Y.Z is older than the minimum required vA.B.C. Run go install github.com/mvanhorn/cli-printing-press/v4/cmd/cli-printing-press@latest to update." Current-run state is resolved from $PRESSRUNSTATE. Published CLIs are resolved from $PRESSLIBRARY. Archived manuscripts are resolved from $PRESSMANUSCRIPTS. Step 1: Parse Arguments Read the user's input after /printing-press-score. The input is free-form — interpret intent, don't enforce syntax. …
