AI Security Review
scanned 5d ago · by lpm-firewall-aiThe automatic, unprompted setup and replacement of a user-home agent extension leave a concrete lifecycle risk, though the behavior is limited to this package’s own skill. The evidence supports a warning for agent extension lifecycle risk, not a confirmed attack warranting a publish block.
Static reason
High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source
Trigger
Installing the package when neither installer opt-out environment variable is set.
Impact
This creates an agent extension without a separate affirmative setup step and can replace an existing same-named skill.
Mechanism
The installer recursively removes each target directory, then copies the bundled skill into it.
AI rationale
The automatic, unprompted setup and replacement of a user-home agent extension leave a concrete lifecycle risk, though the behavior is limited to this package’s own skill. The evidence supports a warning for agent extension lifecycle risk, not a confirmed attack warranting a publish block.

Decision evidence
public snapshotAI called this Suspicious at 88.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The manifest runs the skill installer automatically through a postinstall hook.
- The installer targets the user’s Claude Code, agents, and Codex skill directories.
- The hook runs unless an environment variable opts out; it skips source checkouts.
- It recursively removes and replaces the package’s same-named skill directory at each target.
- The bundled skill describes using the scriptctl CLI and reading its output.
Evidence against
- The installer is limited to the package-owned scriptctl skill directory; the inspected code does not show broader agent settings changes or content export.
- The installer supports an environment-variable opt-out.
