Dependency Check

Before proceeding, verify that at least one of gh or glab is available:

command -v gh >/dev/null 2>&1 || command -v glab >/dev/null 2>&1 || echo "MISSING: gh or glab — install one to use changelog retcon"

If neither is available: warn the user but allow changelog preview to proceed (it only needs git).

Critical Rules

Markdown output: soft-wrap prose, never hard-wrap — when this skill writes a .md artifact (changelog entries, previews, or any generated document), write each paragraph as one continuous line; do not insert manual newlines to wrap prose at a fixed column width. Newlines still separate paragraphs, list items, headings, and code fences. (If a markdown formatter is available, prettier --prose-wrap never enforces this deterministically.)
