AI Security Review
scanned 3d ago · by lpm-firewall-aiNo confirmed malicious attack surface was established. The main risk is an install-time cosmetic rewrite of a dependency OAuth callback page, but it does not collect secrets, contact a remote host, or alter agent instructions.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
npm install runs postinstall; CLI subcommands trigger runtime networking or updates
Impact
No confirmed unconsented credential theft, exfiltration, persistence, destructive action, or AI-agent control hijack
Mechanism
benign CLI agent runtime with user-invoked integrations and local state writes
Rationale
Static inspection found risky but package-aligned CLI capabilities and a cosmetic postinstall dependency patch, with no concrete exfiltration, stealth, destructive behavior, or unconsented AI-agent control-surface mutation. Scanner findings are explainable by a large AI-agent CLI with bundled skills and channel integrations.

Decision evidence
public snapshotAI called this Clean at 84.0% confidence as Benign with high false-positive risk.
Evidence for block
- package.json defines postinstall: node scripts/brand-oauth-page.mjs
- scripts/brand-oauth-page.mjs writes a dependency OAuth callback page under @earendil-works/pi-ai
- CLI contains user-invoked network/update/package-manager flows in scripts/install-convex.mjs, scripts/convex-push.mjs, dist/cli/commands/update.js
Evidence against
- brigade.mjs only checks Node version, filters warnings, enables compile cache, and imports dist/entry.js
- dist/entry.js dispatches CLI commands; no credential harvesting or install/import-time exfiltration found
- postinstall script is idempotent cosmetic branding using bundled assets and exits silently if target dependency page is absent
- dist/security/injection-patterns.js is a defensive scanner for prompt injection/exfil patterns; Trojan-source-like characters are in regex literals/comments, not hidden control flow
- Network endpoints observed are package-aligned: local Convex, GitHub Convex releases, Slack/Telegram channel APIs, npm update check
