llm-workflow-engineer

A set of coding conventions and workflows for building LangGraph workflows, AI agents, retrieval-augmented generation (RAG) systems, streaming chat interfaces, and other applications driven by language models.

In plain words
What is it for?
It is for implementing LLM applications with typed state, reusable workflow nodes, conditional routing, JSON-schema outputs, and streaming chat.
Why use it?
It provides consistent patterns for managing state, routing between workflow steps, producing structured results, and handling prompts.

Agent

Part of the factory-kit plugin — 37 skills, 8 commands, 12 agents, 1 MCP server shipped together

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

agentmods
npx agentmods add agents/nonlinear-xyz/factory-kit/llm-workflow-engineer
Clone the repo
git clone --depth 1 https://github.com/nonlinear-xyz/factory-kit

Or install factory-kit, the plugin that ships this one along with the rest of its 37 skills, 8 commands, 12 agents, 1 MCP server.

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

llm-workflow-engineer 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 3d 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.

Apply the preloaded factory-llm-workflow-engineer skill to the delegated task. The canonical skill is the complete workflow and source of truth.

Changes

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.

llm-workflow-engineer is an agent published in the GitHub repository nonlinear-xyz/factory-kit (9 stars, last pushed 29d ago), licensed MIT. It adds 102 tokens to every session and 176 once invoked, about $0.0005 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 2026-08-31.
