Two WeChat decryption tools are often compared, but usually along the wrong axis. The real difference is not how many features they have, but how they obtain the SQLCipher key. This article breaks both down at the principle level: SQLCipher’s per-database key model, two mechanisms for extracting keys from memory (LLDB + entitlement vs. sudo + mach_vm), and corrections to two mistaken judgments I made in the first version after actually running wechat-use on my own machine.

AgentParty is a very thin bus that lets coding agents from different machines and different companies — along with the people behind them — stay in the same channel to @ each other, stand by, and hand things off. This article explains it along three lines: what it is and what problem it solves; what scenarios it can be used in; and how its underlying architecture is built.

From the five-task matrix and layered architecture to DiT/VAE/T5/distributed execution/schedulers, this article breaks down, layer by layer, the real pitfalls in the Wan2.2 source code where the documentation and implementation diverge.

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.
