list_workflows

Read-onlyIdempotent

Retrieve names of workflows saved in ComfyUI's workflow browser. Use the search parameter to filter by case-insensitive substring matching.

Instructions

Workflows already saved in ComfyUI's workflow browser (userdata). Use a returned name with import_workflow(name=...) to load one WITHOUT pasting its JSON. search filters names (case-insensitive substring).

Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Description adds context beyond annotations: data source (userdata), case-insensitive substring search. Annotations already indicate read-only and idempotent, which aligns with non-destructive listing.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two concise sentences front-loading purpose and usage. Every sentence adds value with no redundancy.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple list tool with one optional parameter and an output schema, the description provides sufficient context: data source, filtering, and downstream use.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

With 0% schema description coverage, the description compensates by explaining the search parameter's behavior (case-insensitive substring filter) and default value.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states it lists saved workflows from userdata, explains how to use the returned names with import_workflow, and describes the search parameter. It distinguishes from sibling tools like import_workflow.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

It tells when to use (to list saved workflows) and how to use the results (with import_workflow). It does not explicitly state when not to use, but the context is clear for a listing function.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
