What is claude-workflows?

A guide to dynamic workflows: JavaScript programs that coordinate many subagents in one background run. A subagent is another agent delegated a focused piece of work.

Use it for codebase-wide bug sweeps, large file migrations, source cross-checking, or plans developed from several independent viewpoints.

It helps handle large, repeatable jobs that need more agents or more coordination than one conversation can manage.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00078	$0.01743
Opus 5.5	$0.00031	$0.00697
Sonnet 5.5	$0.00016	$0.00349
Haiku 4.5	$0.00008	$0.00174

Security

Grade A, and why

claude-workflows scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Claude Code Workflows

A dynamic workflow is a JavaScript script that orchestrates subagents at scale. Claude writes the script for a task you describe, a runtime executes it in the background, and only the final answer returns to your conversation. The script — not Claude's context — holds the loop, the branching, and the intermediate results, so one run coordinates tens to hundreds of agents instead of the few a single turn manages.

Status: research preview, Claude Code v2.1.154+. Available on paid plans (Pro toggle in /config; Max, Team, Enterprise) and via the Anthropic API, Amazon Bedrock, Google Cloud Vertex AI, and Microsoft Foundry.

When to use a workflow

Reach for a workflow when fan-out exceeds one turn, when the orchestration itself must be repeatable, or when work needs independent verification passes before results reach you. Examples: a codebase-wide bug sweep, a 500-file migration, research that cross-checks sources, or a hard plan drafted from several angles before commitment.

Use a single subagent (the Agent tool) for one-off delegated work whose result lands directly in your context. Use a skill for instructions Claude follows inline. Use a workflow when neither scales.

Aspect	Subagents	Skills	Workflows
Scale	A few tasks per turn	Same as subagents	Dozens to hundreds of agents per run
Intermediate results live in	Claude's context	Claude's context	Script variables
What's repeatable	Worker definition	Instructions	The orchestration itself
Interruption	Restarts the turn	Restarts the turn	Resumable in the same session

How to trigger a workflow

Workflows require explicit opt-in. Three paths:

Include the word "workflow" in the prompt. Claude writes and runs a workflow script for the task — e.g. Run a workflow to audit every endpoint under src/routes/ for missing auth checks.
/effort ultracode. Combines xhigh reasoning with automatic orchestration; Claude decides per task when a workflow is warranted. One request can spawn several workflows (understand → change → verify).
Run a saved or bundled workflow as /<name>. /deep-research is the built-in workflow; scripts saved to .claude/workflows/ become their own commands.

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
