install_workflow_dependencies

Resolves missing custom nodes required by a ComfyUI workflow and installs them via ComfyUI-Manager.

Instructions

Resolve and install the custom node packs a ComfyUI workflow requires via ComfyUI-Manager. Determines the missing packs, resets the Manager queue, queues the installs, starts the worker, and reports what was installed/already-present/unresolved. Runs server-side through ComfyUI-Manager on the connected instance (works against a local OR remote --comfyui-url target); a ComfyUI restart is typically needed before new nodes load. Mirrors comfy-cli node install-deps.

Behavior5/5

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

No annotations provided, but the description fully discloses behavior: server-side execution, works against local/remote targets, requires restart after install, and details the process flow.

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?

The description is a single paragraph of four sentences, each adding value: purpose, process, side effect, and CLI equivalent. No unnecessary words.

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

Completeness4/5

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

No output schema, but the description states what the tool reports (installed/already-present/unresolved). It covers the action, side effects, and expected result sufficiently for an installation tool.

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?

Schema coverage is 100% with a description for 'workflow'. The tool description adds context about API format (JSON string or object), which goes beyond the schema's explanation.

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 the tool resolves and installs custom node packs required by a ComfyUI workflow via ComfyUI-Manager. It lists the steps and distinguishes from sibling tools like install_custom_node (for individual nodes) and sync_node_dependencies.

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?

The description mentions the need for a ComfyUI restart and mirrors a CLI command. It implies usage for workflow dependencies but does not explicitly contrast with similar tools or state when not to use.

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