[cost\_intel] Using Sonnet/Pro for deterministic code linting and style checks
Deploy Claude 3 Haiku with constrained JSON schemas for deterministic pass/fail checks \(import sorting, type coverage, regex ban lists\), achieving 97% of Sonnet's accuracy at 1/10th the cost
Journey Context:
Sonnet excels at ambiguous aesthetic judgments \(naming, architecture\), but for deterministic rule-based checks, Haiku with constrained output schemas performs nearly identically. The failure mode is using Haiku for 'suggest refactorings' where multi-step reasoning collapses, but for binary or JSON-structured outputs against clear rules, the cost-quality curve flattens at the small model tier. Common error: paying Sonnet rates for glorified regex work.
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
