ACE - Handbook Integration Codex

Codex CLI provider integration for ACE handbook skills and workflows. ACE Logo

Gem Version Ruby License: MIT

Works with: Claude Code, Codex CLI, OpenCode, Gemini CLI, pi-agent, and more.

ace-handbook ace-handbook-integration-codex maps canonical ACE handbook skills into Codex-compatible projection assets so that skill invocations from Codex CLI resolve correctly while keeping semantics unchanged from the definitions in ace-handbook.

Use Cases

Run handbook workflows in Codex contexts - keep the same behavior while using Codex-native execution entrypoints, so agents running under Codex CLI get the same skill intent as any other provider.

Avoid duplication across providers - update canonical skill definitions once in ace-handbook and generate Codex-specific projections automatically from shared contracts.

Keep integration delivery minimal - maintain a focused provider shim layer with only the manifests and projection assets needed for Codex compatibility.
