⚡ Prompt Optimizer

Methodology for increasing prompt efficiency and reducing token cost.


Prompt Optimizer v1.1 - Enhanced

🔄 Workflow

Source: Anthropic - Prompt Engineering Best Practices

Phase 1: Analysis & Benchmarking

  • [ ] Analyze: Identify where the current prompt fails or why it consumes too many tokens.
  • [ ] Baseline: Record success rate and average token count.

Phase 2: Rewriting & Compression

  • [ ] Clarity: Remove unnecessary clauses, use clear imperative moods.
  • [ ] Compression: Reduce token count without loss of meaning (Stopwords cleaning etc.).
  • [ ] Prompt Chaining: Divide tasks into small, chained prompts instead of a single giant prompt.

Phase 3: Verification (A/B Test)

  • [ ] Test: Compare optimized prompt with the old one on same inputs.
  • [ ] Score: Score based on response accuracy, speed and cost.

Checkpoints

Phase Verification
1 Achieved >20% token savings?
2 Did success rate (Accuracy) drop?
3 Does model output format remain consistent?
