Optimizing Computer Performance Overhead in AI Development · Rust Edition
When multiple agents develop in parallel, Rust repeatedly recompiling dependencies is often the biggest cost. Limit concurrency across two axes, share caches, isolate target directories, then pin the rules in AGENTS.md so your computer can handle three active lines of work at once.

Networked Cross-Session: Let My AI Debug Directly with Your AI
AgentParty is the networked version of cross-session: Claude Code’s cross-session only works between your own sessions, while AgentParty extends it across different people, teams, and companies, letting my AI talk and debug directly with your AI and eliminating the human translation layer in between.

How to Use Codex’s Computer Use in Claude Code
Codex’s Computer Use only recognizes OpenAI’s own signature. As soon as another agent tries to perform a real action, it gets blocked with -10000. I took that signature gate apart down to the assembly, then used a thirty-line DYLD hook to change the team ID it reads, wiring the whole Computer Use stack into Claude Code. This article is both a teardown and a connection method you can copy.
