Octopus OS: an agent harness with a 45k-line Rust kernel that edits itself
max_paperclips · x · 2026-10-25
Developer @miu21590 unveiled Octopus OS, a reinvented agent harness, drawing attention from @TheodoreGalanos and @maxpaperclips.
- Core idea: agents can edit their own harness mid-task — self-improvement isn't a bolted-on stage but native to the architecture.
- Implementation: 8 months of work, a 45k-line Rust kernel, and an OS-like design; system state lives in JSON files, with goals acting as real environments containing inputs, outputs, and custom triggers.
- Discussion: Galanos agrees self-improvement should be part of the agent's being, drawing a parallel to RLMs — the key insight being decomposition at the core, not just an agent with a REPL, which many initially missed.
