Description

Installing the published npm package @openclaw/voice-call fails when installed standalone (outside the OpenClaw monorepo).

The published tarball contains "openclaw": "workspace:*" in devDependencies, which npm does not support. As a result, npm install fails with EUNSUPPORTEDPROTOCOL.

This is the same issue reported in #6879 for @openclaw/nostr.

Steps to Reproduce

openclaw plugins install @openclaw/voice-call

or manually:

npm install @openclaw/voice-call

Actual Behavior

npm install failed:
npm error code EUNSUPPORTEDPROTOCOL
npm error Unsupported URL Type "workspace:": workspace:*

Expected Behavior

The package should install successfully as a standalone npm package.

Environment

• OS: Linux
• Node.js: v24.13.0
• npm: 11.6.2
• OpenClaw: 2026.2.1

Workaround

cd ~/.openclaw/extensions/voice-call
cat package.json | jq 'del(.devDependencies)' > package.json.new && mv package.json.new package.json
npm install --omit=dev

Suggested Fix

The build/publish process should resolve workspace:* dependencies to concrete versions or remove devDependencies before publishing to npm.
