Multi-agent orchestration for Claude Code, ported from oh-my-openagent
npx claudepluginhub whiskey-tango-foxtrot-gmbh/sisyclaudeMulti-agent orchestration for Claude Code, ported from oh-my-openagent. Greek mythology-themed agents for planning, execution, research, and review.
Whiskey-Tango-Foxtrot-GmbHA port of oh-my-openagent's Greek mythology-themed agent system, brought back to Claude Code.
This project exists because of work that happened outside the Anthropic ecosystem — and the story is worth telling.
In early 2026, oh-my-openagent (originally "oh-my-opencode") by @code-yeongyu introduced a multi-agent orchestration layer for OpenCode — a model-agnostic open-source coding agent. The system used Greek mythology-themed agents (Prometheus for planning, Hephaestus for deep implementation, Oracle for architecture decisions, etc.) to route tasks to the right specialist. It grew to 43k+ GitHub stars and became one of the most popular plugins in the OpenCode ecosystem.
Around the same time, Anthropic moved to block third-party tools from using Claude subscription credentials via OAuth, citing terms-of-service violations around identity spoofing and token routing. This action — which broke OpenCode, Cline, RooCode, and others overnight — was partly attributed to oh-my-openagent's success. The dispute escalated through formal legal demands, and by March 2026 OpenCode had removed all Anthropic integration entirely.
The oh-my-openagent community built something genuinely innovative during and despite that conflict. Their multi-agent architecture — the idea that a coding assistant should delegate rather than do everything in one context window — proved itself across thousands of real-world projects.
SisyClaude takes the agent architecture and design philosophy pioneered by oh-my-openagent and adapts it for Claude Code's native sub-agent system. Instead of TypeScript orchestration running outside Claude, the agents are defined as markdown agent definitions that Claude Code loads natively.
The name "SisyClaude" is intentional — this is a reduced, Claude-specific adaptation, not a replacement for the original. Think of it as a tribute, not a competitor.
What works well:
What oh-my-openagent does better:
If you want the full experience with provider flexibility, go use oh-my-openagent. This port is for people who prefer (or need) to stay within Claude Code and want better orchestration than the vanilla experience.
| Agent | Role | Model | Invocation |
|---|---|---|---|
| Sisyphus | Main orchestrator — classifies intent, delegates, verifies | Opus | @sisyphus |
| Atlas | Plan executor — delegates ALL implementation, never codes | Opus | @atlas |
| Hephaestus | Autonomous deep worker — never asks, just completes | Opus | @hephaestus |
| Prometheus | Strategic planner — interviews, researches, writes plans | Opus | @prometheus |
| Oracle | Architecture consultant — read-only, effort-tagged advice | Opus | @oracle |
| Momus | Plan reviewer — approval-biased, max 3 issues per rejection | Sonnet | @momus |
| Metis | Pre-planning analyst — catches hidden requirements, AI slop | Opus | @metis |
| Explore | Fast codebase search — structured results, parallel execution | Haiku | @explore |
| Librarian | OSS docs researcher — evidence-based with GitHub permalinks | Sonnet | @librarian |

The agent architecture, naming conventions, and design philosophy in this project are ported from oh-my-openagent by @code-yeongyu. Their work pioneered the multi-agent orchestration pattern for AI coding assistants, and this port would not exist without it.
