AI Security Review
scanned 11d ago · by lpm-firewall-aiThe automatic postinstall performs package-owned OpenCode extension setup in the consumer workspace, creating lifecycle-related control-surface risk. The inspected source shows ownership and conflict safeguards but no concrete malicious behavior, so this warrants a warning rather than a block.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review; previous stored version diff introduced dangerous source
Trigger
Installing the package with lifecycle scripts enabled triggers postinstall.
Impact
OpenCode behavior and workspace contents can change without a separate installer command; existing unowned files and an existing main configuration file are preserved.
Mechanism
The installer selects the consuming workspace by default and copies package-owned agents, commands, tools, and system files into it.
AI rationale
The automatic postinstall performs package-owned OpenCode extension setup in the consumer workspace, creating lifecycle-related control-surface risk. The inspected source shows ownership and conflict safeguards but no concrete malicious behavior, so this warrants a warning rather than a block.

Decision evidence
public snapshotAI called this Suspicious at 88.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The package runs scripts/install.js from its postinstall hook.
- The installer defaults its target to npm's INIT_CWD, so it can write into the consuming workspace during installation.
- The installer copies this package's agents and commands into the workspace's .opencode directories and also installs its tools and system files.
- The installer preserves differing unowned files and keeps an existing .opencode/opencode.json unchanged.
- The build helper invokes npm pack to create a release artifact; that behavior is separate from the postinstall hook.
Evidence against
- The installer limits its agent and command additions to this package's own files and preserves unowned files. The inspected source does not establish credential transfer or remote payload execution.
