| 2 | """Packs each Claude Code plugin under plugins/ into dist/<name>-<version>.zip. |
| 3 | |
| 4 | The zip has the plugin's files at its root (.claude-plugin/plugin.json first), which is what |
| 5 | claude.ai's Customize > Plugins > Add > Upload plugin and `claude --plugin-dir <zip>` take. |
| 6 | Tests and the Codex-only parts stay out. The output is byte-for-byte reproducible: sorted |
| 7 | entries, a fixed timestamp and fixed permissions, so a rebuild of the same sources is the |
| 8 | same file (Diffinery serves a copy of these zips; see apps/diffinery/claude-plugins/README.md). |
