Normalized Telegram record
Newer agent models can reward shorter prompts
OpenAI's migration guidance emphasizes concise instructions, explicit contracts, and less compensating prose for newer models.
Signal contract
OpenAI's migration guidance emphasizes concise instructions, explicit contracts, and less compensating prose for newer models. Prompts accumulated around older failure modes can become noise, so model upgrades should trigger controlled prompt reduction and regression testing. Novelty: incremental. Verification: source-inspected. This New Runtime record is an evidence-linked retrieval unit.
