I finally found a reason to build my own AI agent
Dreams of Code
May 19, 2026
By treating broken builds as low-value tasks rather than technical hurdles, the host built a custom agent system to autonomously fix cross-platform regressions. Running on local hardware and secured by Tailscale, these agents diagnose failures and submit pull requests, effectively eliminating the context-switching tax associated with managing Windows and Linux builds from macOS.
Key insight: Rather than relying solely on generic coding harnesses, the host used the Rust 'Cersei' crate to build a hybrid agent that uses deterministic code for standard API tasks and LLMs only for diagnosing and patching logic, ensuring higher reliability and better observability.
