API capability pack for bounded Raindrop.io REST v1 operations against https://api.raindrop.io only. Reads the authenticated user, collections, tags, bookmarks, highlights, and collection filter counts, and supports approval-gated bookmark creation/update plus collection create/update metadata operations. This is intended for recurring research capture, saved-link review, duplicate/no-tag/broken-link triage, collection setup, and reading-to-memory workflows. Enroll a Raindrop.io OAuth access token or test token connection as bearer auth; no credential is embedded in the manifest. The pack intentionally excludes bulk update/remove, collection deletion, trash/permanent delete, import/export, backups, file upload, cover upload, collection sharing/collaborator APIs, tag rename/merge/remove, highlight create/update/remove, public user lookup, social account connect/revoke, and arbitrary API passthrough.
