Prompt Chaining

Prompt chaining is the technique of breaking a complex task into a sequence of smaller, focused prompts where each prompt builds on the output of the previous one. Instead of asking AI to do everything at once, you guide it step by step — getting better results through incremental progress.

Example

Instead of 'build me a complete e-commerce checkout,' you chain: (1) 'Design the cart data model' → (2) 'Create the cart UI component using that model' → (3) 'Add the Stripe payment integration' → (4) 'Write tests for the checkout flow.' Each step uses the previous output as context.

Prompt chaining transforms AI from a single-shot tool into a step-by-step collaborator. Complex features become manageable when broken into a chain of focused requests.

Why Chain Prompts?

Single complex prompts often produce:

  • Incomplete implementations
  • Inconsistent patterns across files
  • Hallucinations from overloaded context
  • Results that miss important details

Chained prompts produce:

  • Focused, high-quality output at each step
  • Consistent patterns that build on each other
  • Less hallucination per step
  • Opportunities to correct course early

Chaining Patterns

Sequential

Each step feeds the next:

Design schema → Build API → Create UI → Add tests

Refinement

Each step improves the previous:

Generate draft → Review for issues → Fix problems → Polish

Expansion

Start simple, add complexity:

Basic component → Add validation → Add error states → Add animations

Effective Chaining Tips

  1. Start with the foundation — Data models, types, interfaces
  2. Build layer by layer — Schema → API → UI → Tests
  3. Reference previous output — "Using the schema from step 1..."
  4. Verify each step — Don't chain on broken foundations
  5. Keep context — Summarize previous decisions when starting a new chain
