Prompt Chaining

Break work into fixed ordered steps. Validate each handoff.

Goal

Reduce error by making each prompt do one job. Keep handoffs explicit.

Rules

• Use only for fixed sequences.
• Define final output first.
• Give each step one responsibility.
• Use strict handoff schema.
• Validate before next step.
• Stop or retry on bad output.
• Log cost, latency, input, and output when useful.
