A catalog of ChatGPT & Codex plugins, sorted by people.
Two Agent Workflows tools whose own descriptions overlap (shared terms: parallel, execution, opencode, task, workflow). Here's what each project says it does and the public numbers, side by side, so you can pick one in a minute instead of reading two READMEs.
| oh-my-openspec | Workflow Kit | |
|---|---|---|
| What it says it does | Spec-driven development workflow for Codex CLI and OpenCode, with planning, parallel task execution, and mechanical OpenSpec validation. | Full product lifecycle plugin for Claude Code, Codex CLI, and OpenCode: define Vision/Mission/Core → generate workplan → execute with mandatory cross-provider reviewer agents → synthesize deliverables → maintain, with parallel task execution, crash recovery, and AgentOps metrics. |

We haven't run both, so we won't crown a winner. Use the list above to rule one out, then read its README and recent commits before installing. Anything that runs commands on your machine deserves a look at the code.
