## What this examines

The article argues that complex LLM work has moved from single "magic prompts" to chained, tool-using, validated workflows. The article describes a progression from planning chains, information-gathering chains, analysis chains, validation chains, RAG chains, and eventually agents that choose their own next steps.

## Why it matters

The source aligns closely with the vault's LLM-wiki pattern: reliable AI work comes from decomposition, external memory, tool use, validation, context flow, and feedback loops.

## Key ideas

- Complex intelligence is compositional, not monolithic.
- Good workflows plan, identify gaps, call tools, synthesize, validate, and iterate.
- Tool calling lets LLM systems act on knowledge gaps rather than hallucinate around them.
- RAG gives models task-specific memory without forcing all knowledge into a context window.
- Agents extend chains by planning, acting, observing, storing memory, and revising their plan.
