AI Analysis
●●●●GemWizardryCozy
Fits battery monitoring into 301 bytes — pure demoscene craft.
Strengths
- •301 bytes total including ELF headers — extreme constraint engineering
- •Direct syscalls without libc, hand-written x86-64 assembly
- •Actually functional output, not just a toy that prints hello
Weaknesses
- •Linux-only, x86-64 specific, no practical advantage over normal tools
