Building a Multi-Agent LLM Orchestrator with Claude Code: 86 Sessions of Hard-Won Lessons

The idea behind multi-agent LLM orchestration is deceptively simple. Run Claude, Codex, and Gemini simultaneously, then route tasks to whichever model handles them best. After 86 sessions, here is what actually happened: the same security bug surfaced three separate times, TypeScript configuration was ignored in every single session, and API credits ran dry in a single day. TL;DR : In Claude Code multi-agent workflows, context must be injected explicitly -- there is no implicit sharing between agents. Discovered bugs must be committed to code immediately, not filed away for later. The tighter the prompt constraints, the more stable the output. One Command, Three LLMs Running in Parallel Running npx llmtrio opens a browser dashboard where you type a task and three LLMs process it in parallel. Under the hood, it is a 2-phase workflow. Phase one generates a plan. Phase two executes it. scripts/octopus-core.js serves as the orchestration engine, and scripts/dashboard-server.js handles the
