-# Todofile
-
-This is a "to do next" file, particularly useful to keep the human and a coding assistant in sync.
-
-The format is based on [Keep a Todofile V0.0.1](https://coulomb.social/open/KeepaTodofile).
-
-The structure organizes **future tasks** by their impact, just as a changelog organizes past changes by their impact.

-## [Unreleased] - *Active Vibe-Coding State* 💡
-
-This section is for tasks currently being discussed with or worked on by the coding assistant. These are the ephemeral, flow-of-thought tasks.
-
-* **To Add:**
-    * Complete AST Query and Analysis CLI implementation (Issue #15)
-    * Performance Validation CLI implementation (Issue #16)
-    * Enhanced discovery tools validation and refinement
-* **To Refactor:**
-    * Update any missing links in existing documentation to new capability system
-    * Refine capability discovery workflow based on practical usage
-    * Enhance AI assistant integration with capability system
-* **To Fix:**
