What it does
Tanstack AI Memory Hindsight is an agent skill from TanStack/ai. Use when wiring hindsight() from @tanstack/ai-memory/hindsight — a hosted memory adapter that buckets memory per conversation and exposes retain/recall/reflect tools to the model. Requires the optional @vectorize-io/hindsight-client peer.
Its SKILL.md is about 480 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It works with TanStack. The repository describes itself as: 🤖 Type-safe, provider-agnostic TypeScript AI SDK for streaming chat, tool calling, agents, and multimodal apps across OpenAI, Anthropic, Gemini, React, Vue, Svelte, and Solid. The licence is MIT.

What it can do on your machine
Read from SKILL.md and the folder at commit 5a41239. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are typescript).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Tanstack AI Memory Hindsight loads about 477 tokens when it runs. Until then it costs about 67 tokens; SKILL.md has 129 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- description
- Use when wiring hindsight() from @tanstack/ai-memory/hindsight — a hosted memory adapter that buckets memory per conversation and exposes retain/recall/reflect tools to the model. Requires the optional @vectorize-io/hindsight-client peer.
Hindsight Memory Adapter
Hosted recall/save adapter backed by Hindsight. Hindsight owns extraction and
ranking server-side, buckets memory into per-conversation "banks"
({tenantId|_}__{user}__{threadId}), and — uniquely — exposes LLM tools through recall so the
model can retain/recall/reflect directly.
Setup
import { memoryMiddleware } from '@tanstack/ai-memory'
import { hindsight } from '@tanstack/ai-memory/hindsight'
// Build per request from the server-validated session — never from req.body.
function memoryFor(session: { userId: string; threadId: string }) {
const memory = hindsight({ user: session.userId }) // baseUrl defaults to HINDSIGHT_URL
return memoryMiddleware({
adapter: memory,
scope: { threadId: session.threadId, userId: session.userId },
})
}@vectorize-io/hindsight-client is an optional peer dependency, loaded lazily on
first use — install it where you use hindsight().
Options
user— durable user id for the bank key (falls back toscope.userId).baseUrl— Hindsight server URL (defaultHINDSIGHT_URLorhttp://localhost:8888).budget— recall budget:'low' | 'mid' | 'high'(default'mid').onToolRetain/onToolRecall— callbacks fired when the model uses the memory tools.
Scope fields: bank id is {tenantId|_}__{user}__{threadId}. namespace is ignored.
Tools
recall returns hindsight_retain, hindsight_recall, and hindsight_reflect in its
tools plus a toolGuidance block. memoryMiddleware merges them into the run so the
model can manage long-term memory itself.
