claude-code - 💡(How to fix) Fix [FEATURE] Don't re-prompt for approval on WebFetch cache hits

Preflight Checklist

• I have searched existing requests and this feature hasn't been requested yet
• This is a single feature request (not multiple features)

Problem Statement

When WebFetch is called twice with the same URL inside its 15-minute cache window, the response is served from cache (no new outbound request) — but the user is still prompted to approve the second call.

(Claude Code itself claims this cache exist - I have not verified)

The agent somtimes issues multiple narrow prompts against the same page during iterative exploration. Each re-fetch is a fresh LLM pass against cached content, which is cheap and safe, but the repeated approval prompts add friction and discourage the pattern.

This likely generalizes — any tool with a response cache should treat cache hits as not requiring re-approval.

Proposed Solution

If the response is served from cache, skip the permission prompt. The user already approved a fetch that produced that exact bytes-on-disk; there's nothing new to consent to.
