Content-addressed caching slashes LLM costs for code reviews
CommitBrief caches LLM responses using a SHA-256 hash of the diff, system prompt, provider, model, language, and schema version. A cache hit costs only a disk read, avoiding token fees and latency. Invalidation is automatic—changing any input alters the key, so old entries are never looked up.

The approach elegantly sidesteps cache invalidation logic, but its real-world value depends on how often identical diffs are reviewed in practice.
