Returns up to four sections — organizations, catalog entries (products + standalone sources folded into one list), curated collections (cross-org playlists), and releases with CHANGELOG chunks interleaved by relevance.\n\nUse `type` to narrow the surfaces you want and skip the expensive paths. For example, pass `type: ['catalog']` to look up a known entity by name (fast, registry-only); pass `type: ['releases']` when you only care about release content and want to avoid entity lookups. Omit `type` to search all four.\n\nCollections surface via two paths: a direct match on the collection's name/description (lexical in every mode, plus a vector match in hybrid/semantic mode) and a member rollup that includes every collection containing one of the matched orgs. Member rollups carry a list of result-set org slugs that triggered the rollup so a UI can render an \"includes X\" hint.\n\nUse `entity` (product slug / prod_ id OR source slug / src_ id) to scope release results to one catalog entry. Product identifiers expand to every source under the product. Use `organization` to scope to a whole org. Release retrieval defaults to hybrid (FTS5 + semantic vectors fused via RRF); it silently degrades to lexical when vector infra is unavailable and flags the result.",

This tool sends requests to an external URL you supply and can delete or disable delivery, so treat it as a write.\n\nPass `workspace` (an id or slug) to act on a workspace's webhooks instead of your personal ones; workspace webhooks are always org-scoped (`scope: \"follows\"` is personal-only and is rejected up front). Only workspace owners and admins can create, update, delete, or rotate a workspace webhook — any member can test one.\n\n`action: \"create\"` needs `url` and `format` (`json`, `slack`, or `discord`), plus either `scope: \"follows\"` (personal only — everything you follow) or an org-scoped target: `org` (an org slug or `org_…` id), optionally narrowed by `product` (slug or `prod_…` id) or `source` (slug or `src_…` id). `action: \"update\"` needs `id` plus any fields to change; pass `source: null` or `product: null` to clear a filter. `action: \"delete\"`, `action: \"test\"`, and `action: \"rotate_secret\"` need only `id`.\n\n`create` and `rotate_secret` return a one-time `signingKey` for `json`-format webhooks — store it now, it will not be shown again. `slack` and `discord` deliveries aren't signed, so those formats never return one.",
