reinstall_custom_node

Uninstalls and reinstalls a ComfyUI custom node to resolve installation problems. Uses ComfyUI-Manager HTTP API with cm-cli fallback.

Instructions

Reinstall a ComfyUI custom node pack (uninstall then install). Uses the ComfyUI-Manager HTTP API with a cm-cli subprocess fallback. A ComfyUI restart may be required.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
idYesRegistry id / module name to reinstall.
versionNoVersion to reinstall (default 'latest').
modeNoComfyUI-Manager data source mode (default 'remote'): 'remote' fetches the live node list, 'local'/'cache' use bundled/cached data.
channelNoComfyUI-Manager channel name (default 'default').
useCmCliNoForce the cm-cli.py subprocess instead of the ComfyUI-Manager HTTP API. Requires a local ComfyUI install (COMFYUI_PATH); errors in remote --comfyui-url mode.
Behavior3/5

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

With no annotations, the description adds some context: reinstall involves uninstall then install, uses HTTP API with fallback, and may require restart. Missing details on destructiveness, reversibility, or authorization needs.

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 sentences, front-loaded with the core action, and no unnecessary words. Highly efficient.

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

Completeness3/5

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

Given 5 parameters and no output schema, the description lacks details on return values or when to use specific parameter settings like mode or useCmCli. Adequate but not comprehensive.

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

Parameters3/5

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

Schema coverage is 100%, so the description adds little beyond what parameters already define. Baseline score of 3 is appropriate.

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 reinstalls a custom node pack by uninstalling then installing, distinguishing it from sibling tools like install_custom_node or update_custom_node.

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

Usage Guidelines3/5

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

The description implies when to use (for reinstallation) but does not explicitly contrast with alternatives like fix_custom_node or provide conditions for use vs. API vs. CLI fallback.

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