AI Security Review
scanned 1mo ago · by lpm-firewall-aiThe package has a concrete user-invoked AI-agent configuration capability, so it warrants a warning under the agent-integration policy. Static inspection found no automatic lifecycle abuse or confirmed malicious payload.
Static reason
High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source
Trigger
A user runs the CLI ai command or invokes the MCP configuration helper.
Impact
A user-selected project can gain AI-agent instructions or a local MCP configuration; this is a guarded capability, not confirmed malicious activity.
Mechanism
The code writes selected project AI context files and can write a localhost server entry to .claude/settings.json.
AI rationale
The package has a concrete user-invoked AI-agent configuration capability, so it warrants a warning under the agent-integration policy. Static inspection found no automatic lifecycle abuse or confirmed malicious payload.
Evidence
packages/cli/src/bin.tspackages/core/src/ai.tspackages/core/src/mcp.tspackage.json.claude/settings.json
Decision evidence
public snapshotAI called this Suspicious at 82.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- The package exposes an explicit CLI ai command that installs AI coding-assistant context files.
- The AI installer writes selected context and skill files under the caller-provided project root.
- The MCP helper can create or update .claude/settings.json with a localhost MCP server entry.
- package.json has no preinstall, install, or postinstall hook; its prepare hook only runs the build.
Evidence against
- No credential collection or export was identified in the inspected paths.
- No unconsented install-time AI-agent configuration mutation was identified.
