Hivemind: Claude Code as Orchestrator, opencode as Free Worker Swarm — Development

Hivemind is an orchestration skill that lets Claude Code act as the brain while delegating grunt work to free opencode workers, cutting token costs. It manages single-worker delegation or parallel swarms with worktree isolation, benchmarking, and fleet patterns, producing summarized results and diffs for review.

✨ What it does

Auto-routing via /hive to single worker, generic swarm, or template.
Single worker delegation with /oc and parallel swarm with /swarm.
Worktree isolation for writing workers to prevent conflicts.
Fleet patterns: /review-panel, /research-sweep, /migration, /test-fleet.
Benchmarking script comparing configs A, B, C with blind grading.
Aggregation and status scripts for deduplication and progress tracking.

🎯 When to use it

When you want to reduce token costs by offloading repetitive or well-defined tasks to free opencode workers.
When you need to parallelize independent subtasks across multiple workers (scout, coder, tester) with isolated worktrees.
When you want to benchmark the cost/performance of Claude solo vs opencode solo vs an orchestrated swarm.
When you need a structured review or research sweep across multiple lenses or angles.
When the user says 'spawn a worker', 'swarm', 'delegate to opencode', or '/oc'.

🚀 How to use

Trigger: /hive

Trigger by using slash commands like /hive, /oc, /swarm, or by asking to delegate to opencode. Provide a clear task description. For swarms, decompose into independent subtasks and ensure writing workers get separate worktrees. Example prompts:

/hive Implement a function to parse CSV files with error handling.
/swarm Research best practices for React state management and summarize findings.

📄 Output: A summary of worker results, diffs for review, and optionally benchmark results in JSONL format.

⚠️ Good to know

Requires external opencode CLI installation and authentication; free-tier rate limits may cause 429s, and worker quality varies so diffs must be reviewed.

❓ FAQ

What is the default model for opencode workers?

The default model is opencode/mimo-v2.5-free, which is free but availability and pricing can change.

Can I delegate secrets or private code to workers?

No, you should not delegate secrets or private code because worker traffic goes to opencode's endpoints.

What should I do if a worker fails?

Retry once, then if it still fails, perform the subtask inline and mark it as '[orchestrator-sourced]'.
