NixOS Development Guidelines (AI Agents)

Auto-generated from feature plans. Last updated: 2026-01-30

Active Technologies

• Python 3.12 + MCP server library (Python, JSON-RPC/stdin transport), click for CLI entrypoint, pytest + coverage for tests, ruff/black for lint/format (002-mcp-server)

• None (in-memory tool definitions; filesystem access for repo interactions) (002-mcp-server)

• Nix (flakes; nixpkgs 25.11) + nixpkgs, flake-parts, sops-nix (003-vps-image-migration)

• N/A (configuration repo) (003-vps-image-migration)

• Documentation set (AI-facing constitution and playbooks) in Markdown (001-ai-docs)

Project Structure

docs/                    # Constitution and playbooks for AI guidance
specs/001-ai-docs/       # Planning artifacts (plan, research, tasks, data model, contracts)

Commands

• Primary work is authoring markdown; no build/test commands required beyond manual validation.

Code Style & Rules

• Follow repo conventions: no blank lines between code blocks; comments only when non-obvious; factor duplication into shared helpers/functions in examples.
• Constitution is authoritative for AI guidance; if human docs conflict, update both with the recorded resolution.
• Keep language business-level and technology-agnostic in AI-facing docs.
