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.
Automatic agent skill installation and recursive stale-directory cleanup create a concrete extension lifecycle risk. The inspected code does not support a malicious classification.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
OpenCode startup after the plugin is enabled.
Impact
Existing OpenCode skill content with colliding managed directory names could be removed or replaced.
Mechanism
It installs bundled skills, writes category pointer files, and removes directories it considers stale.
AI rationale
Automatic agent skill installation and recursive stale-directory cleanup create a concrete extension lifecycle risk. The inspected code does not support a malicious classification.
Evidence
dist/index.jsdist/skill-pointer/pointer-generator.jsdist/skill-pointer/vault-installer.js
Independent scan evidence
public snapshotAI called this Suspicious at 91.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for AI warning decision
- The plugin creates the OpenCode skills directory and runs its skill-pointer pipeline at OpenCode startup.
- The pointer generator recursively removes unexpected matching directories in the active skills directory.
- The vault installer recursively removes skill directories absent from the current bundled index.
- The package metadata has only a publish-time lifecycle script, not an install lifecycle hook.
Evidence against
- No network, credential collection, or command execution was found in the active plugin entrypoint and pointer pipeline.
