+# 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.
+
+1) Implement the  NPM_PUBLICATION_PLAN.md
+2) Make sure that Markitect integration still works fine
+3) Update STANDALONE_PLAN.md and decide if it should be implemented
+

+
+## Completed Tasks
+
+*Recent completed tasks have been documented in CHANGELOG.md following Keep a Changelog format.*
