AI Security Review

scanned 1d ago · by lpm-firewall-ai

The scaffolder can write agent-facing files as part of project creation, including automatically selecting recommended pillars in noninteractive mode. This is a bounded configuration risk, while the postinstall hook itself only prints a hint.

Static reason

One or more suspicious static signals were detected.; source closely matched a different package identity; previous stored version diff introduced dangerous source

Trigger

Running the project scaffolder, including in noninteractive or yes mode.

Impact

Agents that read those project files may be influenced by the generated instructions.

Mechanism

The scaffolder calls the pillars wizard with writes enabled; selected pillars can lead it to write project configuration and agent host shims.

AI rationale

Evidence

cli/scaffold.jscli/pillars-wizard.jscli/host-shims.js.chemx/config.jsonAGENTS.mdCLAUDE.md.cursorrulesllms.txt

Decision evidence

public snapshot

AI called this Suspicious at 78.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

The scaffolder invokes the pillars wizard with writes enabled, using the recommended preset in noninteractive or yes mode.
The wizard can write generated agent host shims when pillars are selected.
The npm postinstall hook prints a setup hint; it does not perform the agent configuration setup.

Evidence against

The wizard protects existing hand-authored shim files from overwrite unless forced.
Error issue posting requires an explicit option or environment opt-in.
