Summary
Malicious code in opencode-skills-collection (npm)
Details
Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.

Independent LPM AI assessment
SuspiciousIndependent AI assessment: suspicious. LPM AI assessed this version as suspicious; the assessments disagree.
Startup installation of bundled agent skills is a first-party agent extension lifecycle risk, so this package should be warned on. The manifest has no install-time hook, and inspected credential-bearing requests target their corresponding services.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
OpenCode starts the installed plugin.
Impact
The package adds its skills to the OpenCode environment, extending the skills available to the agent.
Mechanism
The plugin invokes a pipeline that installs bundled skills and generates pointers in the active skills directory.
AI rationale
Startup installation of bundled agent skills is a first-party agent extension lifecycle risk, so this package should be warned on. The manifest has no install-time hook, and inspected credential-bearing requests target their corresponding services.

Independent scan evidence
public snapshotAI called this Suspicious at 84.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for AI warning decision
- The OpenCode plugin runs its skills pipeline during startup.
- That pipeline copies bundled skills into the OpenCode skill vault and creates active skill pointers.
- The Playwright helper executes code supplied by its caller, so this is a user-invoked capability.
- The Apify helper sends its token to the Apify API, and the Hugging Face example sends its token to Hugging Face.
Evidence against
- The only manifest lifecycle script is prepublishOnly, which runs a build.
- Inspected source does not show credential forwarding to an unrelated destination.
