Codebase Analysis

robbyt/codebase-analysis

Deep architectural analysis of the current workspace using Google Antigravity (`agy`). Trigger when the user needs an architecture overview ("analyze this codebase with agy", "map dependencies with Google Antigravity"), is onboarding to unfamiliar code, exploring legacy systems, or hunting technical debt. Replaces the deprecated gemini-cli `codebase_investigator` workflow.
