Better Github Skill

AVGVSTVS96/better-github-skill

GitHub work via gh CLI: PRs, review conversations, CI failures, repo state. Use when inspecting a PR, reading a review (bodies, comments, inline threads), debugging CI (finding which run failed, why a check or Actions run is red, reading job logs), or composing non-trivial gh commands. Scripts cover what raw gh can't do (thread resolution state) or reliably fumbles (PR snapshots, CI log drilldown); use raw gh directly for everything else.
