Building With Prompting: A Practical System
Pipelining LLM calls where each step's output feeds the next. Prompt Chaining is the practice of decomposing a complex task into a sequence of smaller LLM calls, each handling one transformation, to increase reliability and debuggability. This guide pulls together everything on Onexial tagged prompting — 24 connected nodes across definitions, workflows, tool stacks, comparisons, prompts and applied use cases — and orders it the way you would actually learn it: vocabulary first, then process, then tooling, then execution. Every item below links to a full node with its own examples and connections, so you can go as deep as you need without losing the map.
Core concepts behind Prompting
Before wiring anything together, the vocabulary has to be precise. These 13 definitions cover the terms that show up in almost every Prompting discussion — each one links to a full entry with an example and its own connections inside the graph.
Prompt Chaining
Pipelining LLM calls where each step's output feeds the next.
Chain of Thought
Prompting an LLM to reason step-by-step before answering, often improving accuracy on hard tasks.
Few-Shot Prompting
Showing the model 2–5 examples of the task inside the prompt so it mirrors the pattern.
System Prompt
A high-priority instruction that sets the model's role, tone and constraints for the whole conversation.
Temperature
The randomness knob on an LLM's output distribution.
Top-p (Nucleus Sampling)
Restricting sampling to the smallest set of tokens whose probability sums to p.
JSON Mode
A model setting that guarantees valid JSON output.
Structured Generation
Constraining decoding to match a schema at every token.
Self-Consistency
Sampling multiple answers and picking the majority to reduce errors.
Prompt Template
A reusable prompt with named variables filled at runtime.
Chain-of-Thought Prompting
Instructing a model to think step by step before answering.
Zero-Shot Prompting
Asking a model to do a task with no examples in the prompt.
Prompts you can reuse
Prompts are reusable components. Each of these 11 prompts is written to be dropped into a Prompting workflow with minimal editing, including the context it expects and an example output.

Frequently asked questions
- What is Prompt Chaining?
- Prompt Chaining is the practice of decomposing a complex task into a sequence of smaller LLM calls, each handling one transformation, to increase reliability and debuggability.
- What is an example of Prompt Chaining?
- Step 1 extracts entities, step 2 classifies them, step 3 writes a summary referencing each classification.
- Why does Prompt Chaining matter?
- Pipelining LLM calls where each step's output feeds the next.
- What should I learn after Prompt Chaining?
- Open the related workflows and prompts further down this page: they show how this idea is applied in a real task, step by step.
- What is Chain of Thought?
- Chain-of-Thought (CoT) is a prompting technique where the model writes intermediate reasoning steps before the final answer. Newer 'reasoning' models (o-series, Claude thinking, Gemini thinking) run CoT internally.
- What is an example of Chain of Thought?
- Instead of 'What is 17 * 24?', prompt 'Think step by step, then answer. What is 17 * 24?' — the model breaks it into partial products and gets the correct 408.
- Why does Chain of Thought matter?
