Bom Agent does not ship its own LLM. It reuses your existing Claude Pro and ChatGPT Plus (Codex) subscriptions — no extra bill from Bom.
If your primary CLI errors out, the next one in your priority list takes over — one outage cannot freeze a job.
Worker / Main / Automation / Pack / PackBuilder / Standard — each with isolated tool, memory, and MCP exposure.
Codex runs from a launcher in ~/.bom/runtimes/ so your system Node.js never conflicts.
Claude updates itself; Codex auto-updates through npm latest.
bypassPermissions, dontAsk, and allowedTools patterns cleanly separate per-role capabilities.
Bom never charges for LLM usage — pay only your CLI subscription to the provider.
