| # Patch-bump every plugin whose files changed in a push to main, then tag it. | |
| # | |
| # A plugin's version is the only signal Claude Code has that an installed copy is stale — | |
| # the install cache is keyed by version — so a merge that ships a skill change without a | |
| # bump never reaches anyone who already installed the plugin. Doing this on merge rather | |
| # than in each PR means bot-authored PRs (dependabot, auto-dev) get it for free. | |
| # | |
| # Unlike validate.yml this needs a write token, so it must never run on a fork's PR ref: | |
| # `push` to main only, and everything it executes comes from main post-merge. | |

| # Closes the loop: the bump commit itself touches plugins/*/.claude-plugin/plugin.json | |

| # that alone would do it — this keeps it closed if the token is ever swapped for a PAT. | |
| # | |
| # It doubles as the manual escape hatch (documented in the README's Versioning | |
| # section): put [skip bump] in a merge or squash commit message to land a change under | |
| # plugins/** without publishing a new version. Deliberately matched loosely so a human | |
| # can reach for it, which does mean any message carrying that marker skips. | |
