creating-orchestration-packs

Creates orchestration packs: an orchestrator plus a few narrow subagents (explore, plan, implement, review, verify) with minimal tools per role and one shared handoff-packet contract, built so they run in GitHub Copilot (orchestrator agent with handoffs) and in Claude Code and OpenAI Codex (orchestrator as a command in the main conversation, since subagents there cannot start subagents). Covers this collection's src/packs/ format and hand-written packs in a user's project. Use when one agent's role has grown too broad, when phases need different tools or a fresh context, when review must be independent of implementation, or when a pack fails validation because a handoff target does not resolve. For a single agent, use creating-custom-agents.
