Codex Hooks as Production Harness: Lifecycle Automation Enables Evidence Trails, Approval Gates, and Git Custody for Agent Workflows
With Codex Hooks reaching GA, practitioners are documenting the 'harness engineering' pattern: hooks at tool-use, prompt-submission, and session-stop events create deterministic automation around non-deterministic agent behavior. Use cases include scanning prompts for secrets, running validators before tool execution, logging conversations, creating persistent memories, and enforcing git custody. This bridges the gap between 'agent can code' and 'agent can ship safely.'
