What it does
Port From Langgraph is an agent skill from strands-agents/harness-sdk. Migrate a LangGraph application to Strands Agents while preserving its external entrypoint, routing, persistence, interrupts, limits, and tracing. Use when the user asks to port, rewrite, compare, or plan a migration from LangGraph to Strands.
Its SKILL.md is about 200 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in AI & LLM Engineering, covering Building AI agents. It works with LangGraph. The repository describes itself as: Build an agent harness and control it end-to-end. Open-source SDK for production AI agents in Python & TypeScript - any model, any cloud. The licence is Apache-2.0.
When your agent uses it
- The user asks to port
- Plan a migration from LangGraph to Strands
Example prompts
- “/port-from-langgraph”
What it can do on your machine
Read from SKILL.md and the folder at commit 38afb96. 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.
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
Port From Langgraph loads about 200 tokens when it runs. Until then it costs about 66 tokens; SKILL.md has 59 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.
SKILL.md

Port a LangGraph application to Strands
Read the shared Strands skill and the LangGraph migration guide completely.
Inspect the existing graph before editing. Map model-calling nodes to agents, keep deterministic nodes deterministic, preserve caller-visible interfaces and IDs, and verify routing, resumption, interrupts, limits, and traces with representative cases. Call out any graph-join semantic difference that requires a design choice.
