ace-handbook gives ACE teams a shared way to author, review, and maintain handbook assets with consistent quality gates and repeatable delivery workflows. It covers guides (.g.md), cookbooks (.cookbook.md), workflow instructions (.wf.md), and agent definitions (.ag.md).
How It Works
- Author handbook assets using standardized templates and structure conventions for guides, workflows, and agents.
- Review content through quality-gate workflows that check clarity, formatting, and process compliance.
- Coordinate multi-step documentation changes through orchestration and research workflows.
Use Cases
Author handbook assets with consistent structure - use /as-handbook-manage-guides, /as-handbook-manage-cookbooks, /as-handbook-manage-workflows, and /as-handbook-manage-agents to create and update guides, cookbooks, workflow instructions, and agent definitions with package workflows.
Review handbook content before publishing - run /as-handbook-review-guides, /as-handbook-review-cookbooks, and /as-handbook-review-workflows to catch clarity, formatting, and process issues before updates propagate to integrations.
Coordinate larger handbook deliveries - use /as-handbook-update-docs to plan, execute, and synthesize multi-step documentation changes across package handbook assets.
Integrate with resource discovery and context loading - pair with ace-nav for workflow and resource discovery, ace-bundle for loading complete workflow instructions, and provider integrations (ace-handbook-integration-*) that project canonical handbook skills into provider-native folders.
Sync and inspect provider integrations - run ace-handbook sync to project canonical skills into provider-native folders and ace-handbook status to check integration health across all configured providers.
Extend handbook content in normal projects - put project-specific workflows, guides, cookbooks, templates, and skills under .ace-handbook/ and discover them with protocol URLs (wfi://, guide://, cookbook://, tmpl://, skill://). See Usage Guide for path conventions.
