📄 Description

Overview

Adds a new section to the Sandbox auth proxy doc covering callbacks — the dynamic credential lookup feature that landed in langchainplus#23296.

Static rules pull workspace secrets at sandbox creation time. Callbacks let an integrator host their own endpoint that the proxy POSTs to per-host on cache miss; the response body's headers are injected into the sandbox's outbound request. Useful for short-lived OAuth tokens, per-user-scoped credentials, or anything you don't want to bake into a static rule.

Type of change

Type: Update existing documentation

Related issues/PRs

What the new section covers

  • Configuration fields (match_hosts, url, request_headers, ttl_seconds)
  • Precedence: static rules win over callbacks; first-match-wins within each
  • Proxy → callback HTTP contract: POST {host, port} → response {headers}
  • Fail-closed semantics on non-2xx / transport / parse errors (502 to the sandbox)
  • curl + Python + TypeScript SDK examples

Checklist

  • Tested locally with docs dev (rendered Markdown only — no new components)
  • Code examples mirror the smith-go validator + smith-launcher contract
  • Internal links use root-relative paths (no internal links added in this section)
  • No src/docs.json change needed (existing page, no new route)
