AAS Core — Agentic Awesome Skills Local, agent owned skill stacks for coding agents—from complete catalog access to a reproducible, reviewable plan. Current release: V15.9.0.

Guide capability coverage. MCP session instructions require the agent to evaluate the full project surface—from architecture, domain behavior, data and integrations through testing, security
