Zeroshot functions as an autonomous coding agent orchestration system running in the terminal. It coordinates a planner that translates tasks into acceptance criteria, an implementer that modifies code in isolated workspaces, and independent validators that run automated checks. The system iterates through planning, implementation, and validation loops until code is verified or rejected with reproducible failures. It supports multiple AI providers (Claude, Codex, OpenCode, Gemini) and issue platforms (GitHub, GitLab, Jira, Azure DevOps).
