I've also made the decision that command-line arguments should never change the behavior of the compiler itself. They may only change verbosity, perform additional actions like --execute, or facilitate clean builds (--ignore-cache). This constraint causes configurations which are important to successfully build a project to reside within the project's code. The use of external build systems and .sh scripts diminishes when all the options are "built-in".

Claude Code worked for 20 or 30 minutes in total, and produced a Z80 emulator that was able to pass ZEXDOC and ZEXALL, in 1200 lines of very readable and well commented C code (1800 lines with comments and blank spaces). The agent was prompted zero times during the implementation, it acted absolutely alone. It never accessed the internet, and the process it used to implement the emulator was of continuous testing, interacting with the CP/M binaries implementing the ZEXDOC and ZEXALL, writing just the CP/M syscalls needed to produce the output on the screen. Multiple times it also used the Spectrum ROM and other binaries that were available, or binaries it created from scratch to see if the emulator was working correctly. In short: the implementation was performed in a very similar way to how a human programmer would do it, and not outputting a complete implementation from scratch “uncompressing” it from the weights. Instead, different classes of instructions were implemented incrementally, and there were bugs that were fixed via integration tests, debugging sessions, dumps, printf calls, and so forth.
