-description: Use this skill when working with Conductor's context-driven development methodology, managing project context artifacts, or understanding the relationship between product.md, tech-stack.md, and workflow.md files.
+description: >-
+  Creates and maintains project context artifacts (product.md, tech-stack.md, workflow.md, tracks.md)
+  in a `conductor/` directory. Scaffolds new projects from scratch, extracts context from existing
+  codebases, validates artifact consistency before implementation, and synchronizes documents as the
+  project evolves. Use when setting up a project, creating or updating product docs, managing a tech
+  stack file, defining development workflows, tracking work units, onboarding to an existing codebase,
+  or running project scaffolding.
