[Anthropic Launches Claude Code Session Cost-Saving Guide: Cache Hits Can Reduce Costs by 90%] According to the Anthropic blog, Anthropic has summarized six major cost-saving techniques for Claude Code. The key points include: using `/clear` to clean up context promptly between different tasks, determining the model and inference intensity at the start to avoid mid-session switches that disrupt prompt caching, and attaching code via `@file` to replace additional Read calls. It is also recommended to add silent parameters for lengthy output commands or delegate execution to sub-agents, use `/context` in new sessions to check and remove unnecessary loaded content, and compress conversations with `/compact` before exiting.
