update-release-graph

Update the HAL+JSON release information graph when new .NET releases ship. Regenerates index files across the version hierarchy (root → major → patch), timeline hierarchy (timeline → year → month), llms.json, and downloads using graph generator tools. USE FOR: adding a new patch release to the graph, adding a new major version, updating timeline entries after a release, refreshing the graph after source data changes. DO NOT USE FOR: supported-os.json changes (use update-supported-os skill), querying the graph (use dotnet-releases skill on release-index branch), editing generated graph files by hand (update source data and regenerate).

update-existing-branch

Refresh an existing .NET release-notes milestone branch set incrementally. Checks whether the VMR ref moved, regenerates `changes.json` only when needed, merges the delta into `features.json`, integrates new material into existing markdown clusters across the per-component branches, and responds to review feedback. USE FOR: reruns on a populated release-notes branch set. DO NOT USE FOR: first-pass generation of a new milestone (use generate-changes, generate-features, and release-notes).

handsontable-dev

Use for ANY work touching the `handsontable/` core package: fixing bugs, adding features, modifying TypeScript types, removing as-casts, writing or debugging plugins, editors, renderers, validators, cell types, hooks, shortcuts, selection, helpers, index translations, or i18n. Also use for how-to questions about core internals (plugin lifecycle, coordinate systems, hook registration, TypeScript conventions). Triggers on file paths under `handsontable/src/` (excluding `3rdparty/walkontable/` which has its own skill), or when the user describes a symptom in the core grid without naming a file. This is the primary entry point for all core Handsontable development — when in doubt, load it.
