The postinstall hook automatically installs a first-party skill into global agent directories, creating a concrete agent-extension lifecycle risk. The inspected skill content is ordinary product guidance and the source shows no separate 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; source fingerprint signature matched known malicious package; routed for review

Trigger

Installing the package runs its postinstall script.

Impact

The installed skill becomes available to those agents without a separate setup action. The inspected skill provides product workflow guidance.

Mechanism

The script creates global skill directories and writes the package’s SKILL.md into them for several agents, including Codex.

Decision evidence

public snapshot

AI called this Suspicious at 91.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

package.json runs scripts/postinstall.js automatically after installation.
The postinstall hook creates and overwrites a SpecSync skill in global directories for several AI agents, including Codex.
The skill content describes normal SpecSync planning and tracker-sync workflows.
The installer downloads a platform-specific release and checks it against the release checksum file.

Evidence against

The inspected skill contains product workflow guidance, and the installer fetches the release from the project’s GitHub repository.
The inspected sources do not show credential collection, unrelated data transfer, or broader agent configuration changes.
