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

ace-handbook ace-handbook-integration-gemini projects canonical ACE handbook skills into Gemini-native manifest assets so that skill invocations from Gemini CLI resolve to the correct provider entrypoints while preserving shared semantics from ace-handbook.

Use Cases

Run ACE skill workflows in Gemini-native stacks - preserve canonical behavior while using Gemini-native projection format, so agents running under Gemini CLI get the same skill intent as any other provider.

Centralize skill updates - keep shared definitions in ace-handbook and avoid provider-specific drift by generating Gemini projections from one canonical source.

Ship lean provider packs - support only the provider shims and manifests needed for Gemini compatibility, keeping integration scope minimal.
