Dynamic Workflows in Claude Code: A Complete Guide to Multi-Agent Harnesses

Dynamic Workflows in Claude Code: A Complete Guide to Multi-Agent Harnesses

Load this book when:

• You are deciding whether a task should run as a Claude Code dynamic workflow instead of a single turn.
• You are choosing which of the six core workflow patterns (classify-and-act, fan-out-and-synthesize, adversarial verification, generate-and-filter, tournament, loop-until-done) fits a task.
• You are diagnosing agentic laziness, self-preferential bias, or goal drift in a long or parallel task.
• You are wiring ultracode, /goal, or /loop into a workflow and need the exact trigger and stop-condition mechanics.
• You are routing subtasks across Haiku/Sonnet/Opus or setting a token budget for an orchestration.
• You want to understand Loop Engineering — designing systems that prompt agents, not prompting agents yourself.
• You need to build a durable agent loop with automations, worktrees, skills, sub-agents, and memory.
• You are choosing between a dynamic workflow (Claude writes the JS) and a deterministic workflow (you write it once and commit it).
• You need a multi-hour job (bulk API pull, large scrape, long batch export) to survive session restarts, background-task kills, and an absent user.

Valid as of: 2026-06-19, Claude Code v2.1.154+ (dynamic workflows GA). Refresh cadence: review every release that bumps subagent caps, model lineup, or the /goal//loop/ultracode surface (tactical/volatile domain — short cadence).
