The figures
- 80% — The Claude Code team itself found that 80% of system prompts degrade performance. →
- $5 — The tool runs on a $5/month VPS using Docker. →
- $0.028 — With DeepSeek V4 Flash priced at just $0.028 per million tokens, developers can assign lightweight tasks like boilerplate generation or syntax checking to this model, reserving higher-cost models for nuanced logic or debugging. →
- $0.028 — One developer swapped their default backend for DeepSeek V4 Flash and saw API costs drop to just $0.028 per million tokens. →
- 40% — 40% of review tasks needed manual backfill, costing about 15 extra minutes each time. →
- 1,000 tokens — Its original system prompt and tool descriptions came to under 1,000 tokens. →
- 80% — When the Claude Code team decided to slash 80% of their system prompts, most developers expected the model to lose its edge in complex engineering tasks. →
- 80% — Stripping away that redundant 80% removes the cognitive drag holding the model back, freeing native reasoning capacity and cutting the token burn. →
