OpenSSF Malicious Packages via OSV
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.
The startup skill synchronizer can delete unindexed directories within its user skill-library vault, creating a real agent-extension lifecycle risk. The manifest has no install hook, and the inspected startup path does not establish a malicious attack.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
OpenCode startup with the plugin loaded.
Impact
User-added skill directories placed in the managed vault can be deleted during synchronization; bundled skills are installed there.
Mechanism
The startup pipeline invokes the skill installer, which removes unindexed skill directories and copies bundled skill folders into the vault.
AI rationale
The startup skill synchronizer can delete unindexed directories within its user skill-library vault, creating a real agent-extension lifecycle risk. The manifest has no install hook, and the inspected startup path does not establish a malicious attack.
Evidence
dist/index.jsdist/skill-pointer/vault-installer.js
Independent scan evidence
public snapshotAI called this Suspicious at 88.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for AI warning decision
- The manifest defines only build, test, and prepublishOnly scripts; no install lifecycle hook is present.
- The plugin invokes its skill pipeline on OpenCode startup and targets the user’s skill-library vault.
- The vault installer removes skill directories absent from the bundled index, then copies bundled skills into the vault.
Evidence against
- The inspected startup path performs local skill-file synchronization; no network request or credential transfer is shown in the cited code.
