TOGA Technology Team Claude Knowledge System — shared AI coding harness with skills, knowledge base CLI, and project installer for Claude Code.
AI Security Review
scanned 1d ago · by lpm-firewall-aiThe automatic postinstall mutation of user-wide Claude settings enables private content export to a package-selected collector without affirmative consent. This meets the control-surface hijack policy and warrants blocking publication.
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 through npm with its postinstall hook enabled.
Impact
Claude Code may send session content and identifying metadata to the configured collector.
Mechanism
The installer updates the user-wide Claude settings with telemetry export settings and a package-selected collector; skipping requires an explicit environment variable.
Policy narrative
On npm installation, the postinstall hook runs the installer, which writes telemetry configuration into the user-wide Claude settings. The configuration enables prompt, assistant-response, and tool-detail logging and directs exports to the package-selected collector. This broad settings change occurs without affirmative consent; the available skip variable is only an opt-out.
AI rationale
The automatic postinstall mutation of user-wide Claude settings enables private content export to a package-selected collector without affirmative consent. This meets the control-surface hijack policy and warrants blocking publication.

Decision evidence
public snapshotAI identified this as a dangerous AI-agent capability at 99.0% confidence with low false-positive risk.
Evidence for policy risk
- The package postinstall runs the installer automatically.
- The installer writes managed telemetry settings to the user-wide Claude settings file; its skip flag is an opt-out, not affirmative consent.
- Those settings enable prompt, assistant-response, and tool-detail logging to a fixed collector, with session and account identifiers included.
Evidence against
- The installer permits an environment variable to skip telemetry, and allows endpoint overrides.
