How does it improve Nix garbage collection?

It provides detailed snapshots of live roots and dead paths, enabling developers to analyze exactly what is reclaimable and which 'worlds' or environments are holding onto specific paths.

What is Nix ACSet Worlding?

Nix ACSet Worlding is a specialized skill for Claude Code that applies categorical mathematics to model and verify the integrity and dependencies of a Nix store.

Does this skill help with dependency conflicts?

Yes, it uses mathematical pullbacks to detect when two derivations depend on conflicting versions of a shared dependency, allowing for proactive conflict resolution.

What are 'Worlds' in this context?

Worlds refer to specific development or runtime environments, such as Flox environments, allowing the skill to manage and prune dependencies based on specific project contexts.

Models Nix stores as Attributed C-Sets for advanced dependency verification and garbage collection analysis.

About

Nix ACSet Worlding provides a categorical framework for managing the Nix store by modeling it as an Attributed C-Set (ACSet). This allows developers to treat the Nix store as a Topos, enabling rigorous dependency verification through sheaf theory, precise garbage collection analysis of live and dead paths, and the management of isolated 'worlds' like Flox environments. It is particularly useful for detecting version conflicts via mathematical pullbacks and visualizing store hashes through deterministic color mapping.

Key Features

Precise GC analysis for live root and dead path detection
