cache-warmer plugin optimizes Claude Code cache refresh
Understand the story

According to the author, the problem it targets is this: when users step away from Claude Code for more than 5 minutes, the next prompt has to rewrite the prompt cache at full price, so long sessions keep piling up cost and the first response gets slower.

So far the report covers only the plugin’s release and the problem it targets, with no mention of implementation details, performance data, or later updates.
