Documentation

README

From the original repository

Added a managed dev3-bug-hunter skill that installs for all supported agents and gives each bug-hunting run a seeded starting area plus analysis style. The skill is explicitly read-only, now reports findings with a compact ASCII summary table plus detail sections for terminal readability, asks whether critical and medium findings should become separate dev3 tasks, and requires every follow-up task to validate and reproduce the bug before any fix is attempted. The shared ~/.agents/skills copies now also get managed agents/openai.yaml metadata so dev3, dev3-project-config, and dev3 Bug Hunter stay visible in the skill UI after reinstall.
