Dynamic Workflows Harness

Instructions

Use this skill to help you design, prompt, and package Claude Code dynamic workflows.

What dynamic workflows are

• Dynamic workflows let Claude Code “write and orchestrate its own multi-agent harness on the fly” by executing a JavaScript workflow file that can spawn and coordinate subagents.
• Workflows can decide which model each agent uses and whether subagents run in their own worktree.
• If a workflow is interrupted, resuming the session can allow the workflow to pick up where it left off.

When to use dynamic workflows

Use dynamic workflows for complex, high-value tasks where orchestration materially improves outcomes, even if it costs extra tokens.

Core workflow patterns

Use (and compose) these patterns when designing a workflow:

1. Classify-and-act

• Add a classifier step that routes to different behaviors/agents based on task type, or use classification at the end to determine output.

2. Fan-out-and-synthesize

• Split a task into smaller steps, run an agent per step, then synthesize.
• The synthesize step acts as a barrier: it waits for all agents and merges their structured outputs.

3. Adversarial verification

• For each produced output, spawn a verifier/reviewer agent to check it against a rubric or criteria.

4. Generate-and-filter

• Generate many ideas, then filter by rubric/verification, dedupe, and return only the highest-quality results.

5. Tournament selection

• Spawn N agents that attempt the same task using different approaches.
• Use a judging agent to run pairwise comparisons until a winner (or top-k) remains.

6. Loop until done

• For tasks with unknown work size, loop spawning agents until a stop condition is met (e.g., no new findings or no more errors).

Packaging and distribution

• You can save workflows from the workflow menu and store them under ~/.claude/workflows.
• You can distribute workflows via a skill by placing JavaScript workflow files inside the skill folder and referencing them from this SKILL.md.
• If you want flexibility, treat the workflow as a template rather than a script that must be run verbatim.

Bundled templates

• Prompt templates live in templates/:
  • templates/reproduce-flaky-test.md
  • templates/mine-sessions-into-claude-md-rules.md
  • templates/slack-incidents-root-cause-mining.md
  • templates/multi-perspective-teardown.md
  • templates/resume-ranking-with-rubric.md
  • templates/name-ideas-tournament.md
  • templates/rename-model-everywhere.md
  • templates/verify-blog-claims.md

Examples

Example: use the "ultracode" trigger

Ask Claude Code:

• See templates/ultracode-trigger.md

Example: build a triage workflow with quarantine

Ask Claude Code to propose a workflow that classifies items, dedupes against existing tracking, quarantines uncertain items, and then acts.

Example: run adversarial verification

Ask Claude Code to create a workflow where each proposed fix is reviewed against an explicit rubric, and only merged if it passes.
