Bug Report

Plugin

manifest-model-router v6.0.2 (OpenClaw plugin)

Description

The injectProviderConfig function in manifest-model-router writes a minimal model object {id:"auto", name:"auto"} to openclaw.json instead of using the already-defined AUTO_MODEL constant which includes the required input, cost, contextWindow, and maxTokens fields.

This causes OpenClaw to crash with:

Cannot read properties of undefined (reading 'input')

Root Cause

In dist/index.js, the injectProviderConfig function hardcodes:

let providerConfig = {baseUrl, api:"openai-completions", apiKey, models:[{id:"auto", name:"auto"}]}

But AUTO_MODEL is already correctly defined earlier in the same file:

var AUTO_MODEL = {id:"auto", name:"Auto Router", reasoning:false, input:["text"], cost:{input:0, output:0, cacheRead:0, cacheWrite:0}, contextWindow:2e5, maxTokens:16384}

And is correctly used in buildModelConfig and the auth flow — but not in injectProviderConfig.

Additional Issue

The configSchema in openclaw.plugin.json has additionalProperties: false but does not declare apiKey as an allowed property. The plugin code reads config.apiKey, but setting it via openclaw config set plugins.entries.manifest-model-router.config.apiKey fails config validation because the schema doesn't allow it.

Fix

In injectProviderConfig, replace:

models:[{id:"auto", name:"auto"}]

with:

models:[AUTO_MODEL]

And add apiKey to the configSchema.properties in openclaw.plugin.json.
