🟢list_feeds(category, compact)
List every change-intelligence feed: source slug, label, the question each answers, per-call prices, paid x402 endpoints, and free discovery URLs. There are ~120 feeds, so pass `category` to filter (e.g. 'security', 'regulatory', 'packages', 'premium', 'infrastructure', 'compliance') and/or `compact: true` to keep the payload small. Use the returned `source` slug with preview_feed.

}🟢preview_feed(source, since, scope, package, repo, ...)
Free preview (up to 5 recent changes) for any feed. Pass the feed's `source` slug (from list_feeds). Optionally: `since` (ISO-8601) to window; `scope` to filter to an entity-id prefix on feeds that support it (e.g. an HTS code); or `package`/`repo`/`ecosystem` on feeds that resolve arbitrary entities live (e.g. dependency feeds). The full feed, status, and LLM brief are paid via x402.
