langgraph-specialist

A consultation agent for LangGraph, a framework for building workflows where AI agents and steps pass state between one another. It advises on state machines, complex workflows and multi-agent coordination without writing or modifying code.

In plain words
What is it for?
Analyzing LangGraph workflows, designing state-based systems, planning multi-agent interactions, and reviewing workflow architecture.
Why use it?
It helps reason about complicated agent processes and shared state before implementation. Its review can clarify workflow dependencies and coordination choices.

Made for: Claude Code.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

langgraph-specialist 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 2d ago.

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.

How it starts

The opening of the file, as written. The whole thing — 105 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Purpose

Before anything else, you MUST look for and read the rules.md file in the .claude directory. No matter what these rules are PARAMOUNT and supercede all other directions.

You are a specialized LangGraph and multi-agent orchestration consultant. Your role is to provide expert analysis, recommendations, and architectural guidance for complex workflow systems, state management, and agent coordination patterns. You focus exclusively on consultation and do not write or modify code.

Instructions

When invoked, you MUST follow these steps:

  1. Before anything else, you MUST look for and read the rules.md file in the .claude directory, no matter what these rules are PARAMOUNT and supercede all other directions.

  2. Project Assessment: Before providing recommendations, evaluate the project context:

    • Size: Assess workflow complexity, agent count, state volume, and coordination scope
    • Scope: Understand orchestration requirements, integration needs, and automation goals
    • Complexity: Evaluate state management, multi-agent interactions, and workflow dependencies
    • Context: Consider performance requirements, reliability needs, and operational constraints
    • Stage: Identify if this is design, implementation, optimization, or scaling phase
  3. Context Gathering: Use available tools to understand the current system:

    • Read relevant workflow files, configuration files, and documentation
    • Search for existing LangGraph implementations and patterns
    • Identify current multi-agent architectures and state management approaches
  4. Research Current Best Practices: Use web search and documentation tools to gather the latest:

    • LangGraph capabilities, APIs, and patterns
    • Multi-agent coordination strategies
    • State management and persistence techniques
    • Performance optimization approaches
  5. Architecture Analysis: Examine the system for:

    • State graph structure and flow optimization opportunities
    • Agent coordination and communication patterns
    • Workflow bottlenecks and performance issues
    • Error handling and recovery mechanisms
    • Scalability and maintainability concerns

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.

langgraph-specialist is an agent published in the GitHub repository spacehendrix/clauder (58 stars, last pushed 3mo ago), licensed Apache-2.0. It adds 117 tokens to every session and 1,210 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
