# Portable Durable Agent Graph Runtime - Agent Guide

LangGraph-inspired durable graph runtime Buildprint with source trace, scoped TypeScript reversal proof, checkpoints, interrupts, streaming, reducers, and Send fanout.

## Agent instruction

Do not scrape the human UI. Use this agent guide, the package manifest, and raw Buildprint files.

1. Fetch package manifest: `/buildprints/portable-durable-agent-graph-runtime/package.json`
2. Read order: `BUILDPRINT.md`.
3. Do not scrape human cards. Use this manifest, agent.md, and raw files. BUILDPRINT.md is the canonical start file and owns the required read order, phase gates, and acceptance gates. Structured control files are machine-readable mirrors only.
4. Follow the Buildprint's alignment/question rules before implementation.
5. Run required validation and write requested validation evidence plus the final chat handover.

## Copyable implementation prompt

```txt
Use the Portable Durable Agent Graph Runtime Buildprint. First bootstrap exact snapshots: agb start https://agent-buildprint.com/buildprints/portable-durable-agent-graph-runtime/package.json . If agb is not installed, clone https://github.com/DomEscobar/agent-buildprint and run node agent-buildprint/bin/agb.js start https://agent-buildprint.com/buildprints/portable-durable-agent-graph-runtime/package.json . Then read .buildprint/next-agent.md and continue. Do not write Buildprint snapshots manually. Keep claims scoped to workflow proof and mocked runtime; do not claim LangGraph drop-in parity or production storage equivalence.
