          Auto-built Manus.ai-compatible \`.skill\` bundle for every skill in k-skill.

          - **\`k-skill-manus-all.zip\`** — combined download containing every \`.skill\` file plus \`INDEX.md\`. Unzip, then drag-drop individual \`.skill\` files into Manus.
          - **\`INDEX.md\`** — human-readable listing of every bundled skill.

          Manus accepts one skill per upload (\`.skill\`/\`.zip\`/folder). See [\`docs/install-manus.md\`](https://github.com/${GITHUB_REPOSITORY}/blob/main/docs/install-manus.md) for the full flow.

          This is a rolling pre-release that is overwritten on every push to \`main\`. Built from commit \`${GITHUB_SHA}\`.
