Nix Profile Manager for Agents

Overview

This skill enables agents to maintain a local Nix profile in a user-provided directory, allowing dynamic installation of tools without requiring system-wide package management or sudo access.

Quick Start: Setting Up a Local Profile

Users should provide a directory in their PATH for the agent to manage, and ensure the AGENT_PROFILE env var contains this directory so the agent knows where it is.

Then the agent just does:

nix profile add --profile "$AGENT_PROFILE" "nixpkgs#git"

The --profile flag tells Nix to store the profile metadata in that location. The bin dir created by Nix in the profile must be in the PATH.
