The August 13 release carried 50 changes: 17 fixes, 12 improvements, 12 security, 6 features, 2 performance, 1 breaking. Highlights are a 662-token "web reading specialist" system prompt that delegates untrusted URL reads to a dedicated WebFetch subagent returning source-grounded reports, subagent forking on by default so subagent_type: "fork" inherits the full conversation and prompt cache, and cross-session @-mentions through SendMessage. r/ClaudeAI The breaking change moves sandbox.ripgrep config out of project settings to user or managed settings only. Fork inheriting the prompt cache is the sleeper item, given today's cache economics story.

The payload only exists if you're a robot. That's the part that should scare you. On August 5 a developer doing PSX game research pointed Claude Code at tcrf.net (The Cutting Room Floor, a well-known game-preservation wiki) and got back a page titled "LLM- / AI Agent-Specific...
Claude Code 2.1.233 added an environment variable configuring the WebFetch session URL cache TTL, with the default unchanged at 15 minutes (Claude Code Changelog). That default is a real problem for any agent polling a status page, a CI endpoint or a changelog inside a long se...
A developer took a 228MB Claude Code standalone binary, cracked it open with Ghidra, ran a MITM proxy and radare2, and identified two independent bugs causing prompt cache to break silently. The result: API costs inflated by 10-20x with no user-visible warning. The first bug:...
Anthropic added it in 2.1.237 on August 20, selectable under Output style in /config or settings.json. The r/ClaudeAI thread asking whether it reduces consumption drew 219 upvotes and a clear consensus of no: cost sits in input context, file reads, and reasoning traces, not us...
- Source: GitHub (ykdojo/claude-code-tips) The most comprehensive single resource for power-user tips. Highlights: (1) proactive context compaction via HANDOFF.md documents; (2) Gemini CLI as fallback when WebFetch fails on blocked sites; (3) skills vs. CLAUDE.md optimization...
A 167-upvote r/ClaudeAI thread with 79 comments asks what people mean by "their harness," and the answers cleanly separate the inner harness (Claude Code, Codex) from a custom outer loop supervising it. The same split shows up in a quoted Anthropic newsletter excerpt describin...
