Awesome Codex Workflows

Curated repositories for building and running development workflows with OpenAI Codex.

This is a selective list rather than a general directory of Codex tools. It focuses on systems where planning, execution, review, or handoff is visible in code, configuration, or runtime behavior. The list also includes infrastructure built to support those workflows. Prompt packs, generic tool collections, and simple wrappers are generally left out.

Start with Codex Workflow Frameworks for workflows that cover planning through handoff. If you already have a workflow, see Workflow Infrastructure & Design for tools to run, secure, or inspect it.

Foundations & Standards

Core Codex projects and shared standards that other workflow repositories build on.

• OpenAI/codex - Official Codex repository, providing the execution runtime that Codex-native workflow layers and orchestration tools build on.
• OpenAI/skills - Official skill catalog for Codex, showing how reusable instructions, scripts, and resources are packaged into workflow building blocks.
• agentsmd/agents.md - Community-led AGENTS.md format that gives Codex and neighboring tools a shared way to express repository-local workflow guidance.
• OpenAI/symphony - Open-source Codex orchestration spec with an Elixir reference implementation, defining issue-tracker-driven workflows where each issue claims a workspace and is driven to a review handoff.

Codex Workflow Frameworks

Reusable Codex-first systems that define how development work moves from planning through completion.

• am-will/swarms - Dependency-aware workflow skills for Codex and Claude that make parallel execution safer through explicit depends_on plans, wave execution, and TDD-oriented validation.
• ArcanEdge-AI/coding-agent-playbook-codex - Installable Codex instructions, skills, and role profiles for scoped engineering work, selective delegation, independent review, and validation, with the main agent retaining responsibility for implementation, integration, and final acceptance.
