oh-my-dag vs nac

oh-my-dag: Oh-my-dag (omd) serves as an orchestration layer beneath your AI coding agent, transforming conversational tasks into structured, checkpointed DAGs. It enforces rigorous verification through exit codes, cross-model critiques, and artifact gates, ensuring the reliability and correctness of agent-generated work.; nac: nac is an open-source agent harness designed for managing ambitious, long-running tasks like experiments, training, and infrastructure. It employs a thread-and-episode architecture where a central orchestrator plans work, launches threads, and receives structured summaries of accomplishments.

Features

oh-my-dag logooh-my-dag
01Exit Code as Finish Line: Tasks conclude when a declared command exits successfully, preventing models from self-certifying completion.
02Rigorous Criterion Verification: Acceptance tests run against pre-work and deliberately wrong artifacts to ensure they genuinely test the solution.
03Multi-Model Orchestration: Allows different LLMs for each node in a DAG, enabling tailored model selection and cross-family second opinions for critical tasks.
04Resumable & Checkpointed Workflows: Every completed node is atomically saved to disk, allowing interrupted work to resume from the last checkpoint, saving time and billing.
05LLM-Free Retrieval: `omd_web` performs web searches and fetches without an LLM in the loop, ensuring factual accuracy based on retrieved content rather than model memory.
nac logonac
01Agent Harness for long-running, ambitious tasks
02Thread-and-Episode Architecture for task decomposition
03Central Orchestrator for planning and thread launching
04Structured Summaries (Episodes) of completed work
05Flexible Model Provider Authentication (Arcee, OpenAI, etc.)

Use Cases

oh-my-dag logooh-my-dag
↳Deep Research & Analysis: Conduct multi-stage research pipelines involving seeded crawls, fan-out lenses, judge panels, and gap rounds using different models for each stage.
↳Automated Design Argumentation & Specification: Argue design choices and then generate executable specifications (e.g., `/omd-grill` followed by `/omd-contract`).
↳Cross-Model Code Review: Perform multi-dimensional code reviews, falsifying findings across different models to ensure comprehensive and unbiased feedback (`/omd-review`).
↳Automated Debugging Workflows: Systematically reproduce issues, lock scope, test parallel hypotheses, and verify fixes (`/omd-debug`).
↳Controlled Delivery of Decision Maps: Manage decision maps in Git, ruled by user-defined triggers, preventing unattended merging (`/omd-deliver`).
