AAS Core v20.2.0 Released: 2,877+ AI Agent Skills Catalog and Local MCP Plan Preview

On October 29, 2026, the independent open-source project Agentic Awesome Skills (AAS) published AAS Core v20.2.0 as a GitHub release. It provides local catalog discovery, agent-owned selection, stack validation, and plan preview for Codex and Claude, backed by 2,877+ SKILL.md playbooks for coding agents including Claude Code, Codex, Cursor, and Gemini CLI. The official GitHub release explicitly says version 20.2.0 has not been published to npm.

AAS Core serves as a local, agent-first control plane that enables Codex or Claude to inspect a project, choose exact skills, validate the stack, and produce an immutable plan preview for human review before changing a target.

Key Features and Architecture in AAS Core

• Local Catalog and MCP Integration: Searches through 2,877+ installable playbooks locally and provides read-only compose_stack tool validation inside Codex or Claude Code.
• Stack Validation and Plan Preview: aas stack validate checks manifest validity, while aas stack plan outputs an immutable preview for review. Manifests enforce a technical limit of 128 skills per stack.
• New Reviewed Skills: Version 20.2.0 adds 5 reviewed skills including bifrost-gateway, comment-to-dm-cta, landing-page, web-design-system, and web-review.
• Security and Dependency Fixes: Patches the qs denial-of-service advisory in boilerplate lockfiles by upgrading from 6.16.0 to 6.16.1.

[!IMPORTANT] Structural and identity validity does not certify semantic fit, compatibility, or operational safety. Apply and recovery features remain experimental opt-in capabilities outside the supported preview path.

Download and Setup Caveat

v20.2.0 is available as a GitHub release, but its npm package has not been published. Use the GitHub source archives or the verified runtime archive attached to the official release. The version-pinned AAS Core guide documents local MCP configuration for Codex and Claude Code, but verify the official release distribution status before installing.
