Summary

Third post in the agent-UI tutorial series. ~2,500 words. Walks through wiring a refund-approval gate using LangGraph's interrupt() primitive and the <ng-template chatInterrupt> slot from @threadplane/chat.

SEO rationale (from research):

  • Primary keyword: angular human in the loop / langgraph interrupt angular
  • SERP is functionally empty — one Medium post owns it today
  • High commercial intent (every enterprise team hits this when their agent touches money/data)
  • Authentic authority match — ThreadPlane's interrupts primitive is purpose-built for this

Position in the series:

Voice check: drafted against docs/gtm/voice.md — title-restated lede, ## Goals block ending in Have fun!, "Let's" workhorse transitions, contractions throughout, italics for emphasis, one 💚 emoji, "freakin' cool," personal disclosure (the Stripe-twice anecdote), forward-link close instead of a marketing CTA, explicit ## Conclusion.

Test plan

  • Local: /blog/human-in-the-loop-langgraph-agents-in-angular renders, lists display bullets, code blocks render with syntax highlighting
  • Local: post appears on /blog grid (not featured) and / Recent Articles section (3 cards now visible)
  • CI: nx lint website clean, nx test website green, nx e2e website green

Review locally before merging. Marked draft / not auto-merged.

🤖 Generated with Claude Code

Third post in the agent-UI tutorial series. Walks through wiring a
refund-approval gate using LangGraph's interrupt() primitive and the
<ng-template chatInterrupt> slot from @threadplane/chat.

Builds on:
- Post #1 (streaming chat) — taught the basics of streaming.
- Post #2 (AG-UI fullstack) — taught vendor-neutral wiring.
- This post — teaches the production concern that comes next: approvals.

SEO target: "angular human in the loop" / "langgraph interrupt angular"
— SERP near-empty, high commercial intent, complements existing posts
without cannibalizing.

Closing in favor of a rewrite against the verified cockpit refund example (PR follows). The v1 draft documented APIs that didn't exist yet; the rewrite uses the shipped ChatApprovalCard + structured-interrupt cockpit flow.
