scrutinize

thananon/9arm-skills

First questions intent and whether a simpler/more elegant approach would achieve the same goal, then traces the actual code path (not just the diff) to verify the change does what it claims. Output is concise, actionable, and every call carries its rationale. Trigger on /scrutinize and proactively whenever the user asks to review, audit, sanity-check, or get a second opinion on a plan, PR, diff, design doc, or proposed code change.

thread-list

assistant-ui/skills

Implements multi-thread (conversation history) management in assistant-ui apps: rendering the prebuilt `ThreadList` next to `Thread`, or building a custom sidebar with `ThreadListPrimitive` and `ThreadListItemPrimitive` (Root, New, Items, Trigger, Title, Archive, Unarchive, Delete). Covers thread CRUD through the `useAui()`/`useAuiState()` API: `switchToThread`, `switchToNewThread`, and per item `rename`, `archive`, `unarchive`, `delete`, `generateTitle`, `initialize`, plus reading `s.threads.threadIds`/`archivedThreadIds`/`mainThreadId`. Includes cloud-backed persistence via `useChatRuntime` + `AssistantCloud` and a local `useRemoteThreadListRuntime` + `InMemoryThreadListAdapter` path. Use when a user wants a thread list/sidebar, switching, searching, sorting, drag-and-drop, or renaming/archiving/deleting conversations. For single-thread state, messages, or composer use runtime; for cloud auth/persistence setup use cloud.
