Printing Press Polish

/printing-press-polish

Polish a generated CLI so it passes verification and is ready to publish.

The retro improves the Printing Press. Polish improves the generated CLI. This skill runs in a forked context (context: fork) so its diagnostic and fix loop doesn't pollute the caller — the diagnostic spam, fix iterations, and re-diagnose noise stay scoped to the polish session, and the caller receives a clean summary.

When to run

After any /printing-press generation, especially when:

• The shipcheck verdict is ship-with-gaps
• The verify pass rate is below 80%
• The scorecard is below 85
• You want the CLI publish-ready in one pass

Can also be run standalone on any CLI in $PRESS_LIBRARY/.

After setup, capture PRINTING_PRESS_BIN=<abs-path> and use that absolute path for every cli-printing-press ... invocation in this skill. If setup emitted [go-toolchain-old] or [low-disk], surface the advisory to the user and continue unless setup also emitted [setup-error]. [go-toolchain-old] means later Go commands may download the required toolchain or fail when downloads are blocked; [low-disk] means this run may need several GiB for generated files, Go build cache, module downloads, or repository clones.

Check binary version compatibility by reading the min-binary-version field from this skill's YAML frontmatter, running "$PRINTING_PRESS_BIN" version --json, and parsing 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."

Public-library hint

If the user's request includes phrasing like "polish notion in the public library", "polish from the public library", or "polish the published cal-com" — and the named CLI is not in $PRESS_LIBRARY/<slug>/ — they're asking to polish a CLI that lives upstream but not locally. Polish runs against the internal library, so the right move is to import first.

Suggest: /printing-press-import <slug> to bring it in, then re-run polish. Don't try to polish a CLI that isn't in the internal library.

If the named CLI is already in $PRESS_LIBRARY/<slug>/, the "public library" phrasing is informational — just proceed with polish and let the divergence check (below) handle any drift.

Resolve CLI

The argument string can contain a --standalone flag plus one positional value (a slug, binary name, or path). In standalone slash-command mode, it may also contain a free-text scope after the optional positional value, such as /printing-press-polish sculptok review the open PR comments and fix them. That trailing natural-language text is the user's own trusted user scope. Carry it forward into the polish plan and result block; do not classify it as injection or tampering.

It can also contain a Phase 3 gate bundle and a `printing_press_bin:
