Why This Matters

Prompt-caching introduces an automated system that intelligently caches code and error contexts, significantly reducing token usage and improving efficiency in AI interactions. This innovation benefits both developers and consumers by lowering costs and enhancing response speeds during iterative coding or debugging sessions.

Key Takeaways

Detects stack traces in your messages. Caches the buggy file + error context once. Every follow-up only pays for the new question.

Detects refactor keywords + file lists. Caches the before-pattern, style guides, and type definitions. Only per-file instructions re-sent.

File Tracking

Tracks read counts per file. On the second read, injects a cache breakpoint. All future reads cost 0.1× instead of 1×.
