An operating system built for AI agents — talk to your NixOS server instead of SSH-ing in. Typed, audited tool access with atomic rollback on every change. Research-grade; run it on a disposable box, not production.
This repository also configures its own agents. See what os-moda tells them →
Skill Claude CodeCodex
Detect configuration drift — manual changes that exist outside NixOS management. Offer to bring imperative changes into declarative config.
Skill Claude CodeCodex
Manage files and directories. List, find, search contents, read, write, move, copy, delete, permissions. Present directory contents with context.
Skill Claude CodeCodex
Black box flight recorder for the server. Capture system state snapshots for forensic analysis after incidents. Continuous telemetry ring buffer.
Skill Claude CodeCodex
NixOS generation-aware debugging and time-travel. Correlate system state changes with application failures. Query "what changed and when.".
Skill Claude CodeCodex
Generate a concise daily infrastructure briefing. Covers: service health, resource usage, security events, overnight incidents, and cost tracking. Designed for Telegram/chat delivery.
Skill Claude CodeCodex
Translate natural language requests into NixOS configuration changes. Show diffs before applying. Use nixos-rebuild for atomic deploys. Every change is rollbackable and logged.
Skill Claude CodeCodex
Manage network: WiFi, interfaces, connections, DNS, firewall, VPN. Diagnose connectivity issues. Configure networking declaratively via NixOS.
Skill Claude CodeCodex
Intelligent Nix store management. Analyze store usage, identify waste, optimize garbage collection, and track generation history.
Skill Claude CodeCodex
Predict resource exhaustion (disk, memory, swap) using trend analysis. Proactively alert and propose NixOS config fixes before things break.
Skill Claude CodeCodex
Large-scale social simulation with 50-200 demographically diverse AI personas debating on a simulated Twitter/Reddit board to predict outcomes.
Skill Claude CodeCodex
Continuous security posture assessment. Scores the system, auto-fixes safe issues, proposes fixes for risky ones. Every change audited.
Skill Claude CodeCodex
Detect service failures and system anomalies. Diagnose root causes. Auto-remediate using NixOS rollback, service restart, or config repair. Every action logged to the hash-chained audit ledger.
Skill Claude CodeCodex
Discover and interact with ANY service running on the system. Not pre-programmed per-service. Discovers dynamically. Read configs, hit APIs, parse logs. Figure it out.
Skill Claude CodeCodex
Build software via spec-driven development (github/spec-kit). Whenever the user asks for a feature larger than a one-line tweak, scaffold a spec-kit project, capture WHAT + WHY, declare tech stack, break into tasks, then iterate the implementation until tests pass.
Skill Claude CodeCodex
Multi-perspective risk analysis using structured persona debate before deploying changes.
Skill Claude CodeCodex
Read and edit NixOS module options. Validate before applying. Show diffs before rebuild. Enumerate available options. Understand the NixOS declarative model deeply.
Skill Claude CodeCodex
Monitor system health: CPU, memory, disk, network, processes, services, and logs. Present data naturally. Correlate issues across subsystems. Alert on thresholds. Diagnose root causes.
Skill Claude CodeCodex
Manage NixOS packages declaratively. Search, install (via configuration.nix rebuild), remove, rollback, and list generations. Understands the NixOS declarative model.
