langgraph-architect

langgraph-architect is a plugin for Claude Code from TheLobbi/claude. Its manifest loads nothing; the 5 commands, 12 agents, 1 MCP server it bundles cost 378 tokens per session together, scanned A, original, MIT.

A builder for LangGraph and LangChain agents, which are programs that use language models in connected workflows. It also covers connecting tools through MCP, a standard for letting AI applications use external services, and making agents available from a command line.

In plain words
What is it for?
Use it to create agent graphs, add nodes and workflow edges, connect MCP servers, configure memory, deploy agents, and expose them as command-line programs.
Why use it?
It brings agent structure, tool connections, memory, testing, and command-line access into one development workflow. This reduces the amount of framework setup needed when building multi-step AI applications.

Security

Grade A, and why

langgraph-architect scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured today.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
