调研方向

Start with js/src/auto-instrumentations/configs/all.ts and js/src/span-origin.ts, then compare existing agent integrations such as claude-agent-sdk, openai-agents, and strands-agent-sdk. Inspect the e2e/scenarios/ directory and the Letta Agent SDK documentation to map the client, session, send, and streaming entry points. Done means Letta appears in the registry and instrumentation names with coverage for its agent execution surface and an end-to-end scenario.

描述

Summary

Letta Agent SDK (@letta-ai/letta-agent-sdk) is the official, actively-maintained TypeScript/JavaScript SDK for Letta's stateful agents — agents with persistent identity, long-term memory, and tool/model state that survives across conversations, models, and machines. Its core agent-execution surface (client.createAgent(), client.resumeSession(), session.send()/streaming) is not instrumented anywhere in this repository.

Note: Letta also publishes an older, now-deprecated REST client, @letta-ai/letta-client (repo letta-ai/letta-node), whose README explicitly states "This package is deprecated... unmaintained and receives no new features," directing users to the Agent SDK instead. This gap report is about the current, supported @letta-ai/letta-agent-sdk, not the deprecated client.

What's missing

  • new LettaAgentClient(...) / client.createAgent(...) — creates a stateful agent.
  • client.resumeSession(agentId) / session.send(...) and its streaming variant — the agent-run execution surface, analogous to other already-instrumented agent frameworks (e.g. claude-agent-sdk, openai-agents, strands-agent-sdk).

None of @letta-ai/letta-agent-sdk, letta-agent-sdk, LettaAgentClient, or letta (case-insensitive) appear anywhere in js/src/, js/src/auto-instrumentations/configs/all.ts (the instrumentation registry), js/src/span-origin.ts (INSTRUMENTATION_NAMES), or any e2e/scenarios/* directory.

Braintrust docs status

not_found — Letta does not appear in Braintrust's integrations catalog. Checked https://www.braintrust.dev/docs/guides/traces/integrations (enumerated tracing/agent-framework/testing integration cards — Letta is absent) and https://www.braintrust.dev/docs (no mention of "Letta" or stateful-agent SDKs).
