A walkthrough of Obmondo Code, an SRE co-pilot CLI built in Go that connects an AI agent to 290+ diagnostic runbooks, SSH command execution, Gitea issue parsing, and time registration — with a strict safety model baked into every layer.

Building a PR Review Bot Under 32K Context: Go AST Diffing, YAML Key Diffing, and Smart Truncation

Wed, 08 Apr 2026 00:00:00 +0000

Artoo, Obmondo’s Mattermost bot, got a PR review engine that runs on a self-hosted Qwen3-14B with a ~32K context window. The key problem: a single Kubernetes PR can have 10,000+ lines of diff. The solution: Go pre-processing that compresses diffs to ~2KB before the LLM ever sees them — using go/ast for Go files, YAML key-level diffing for Helm/K8s configs, and priority-based file truncation. This post covers why each decision was made and what the LLM still cannot do.

Two Go stdlib traps when watching and scanning JSON files on Linux

Mon, 16 Mar 2026 00:00:00 +0000

Two bugs surfaced during a CEO-plan audit of the vuls-exporter codebase that are easy to introduce and silent enough to survive code review. Both involve standard-library primitives that look correct but fail quietly on Linux.

The bugs at a glance

filepath.Glob("**/*.json") does not recurse on Linux — it matches nothing in subdirectories and returns nil, nil.
Raw unix.InotifyAddWatch does not automatically watch new subdirectories — any directory created after the watch is set up is silently ignored.

Bug 1: filepath.Glob does not support `**`
