AI Security Review
scanned 4mo ago · by lpm-firewall-aiThe package has substantial benign, user-invoked media/OSINT functionality, but the postinstall script performs a concrete unconsented mutation of an AI-agent dependency config file. That meets the firewall boundary for blocking lifecycle AI-agent control-surface mutation despite no credential or network abuse. Product guard normalized a concrete AI-agent control hijack publish_block to the blockable dangerous-capability shape.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
npm install / package postinstall
Impact
Changes pi-coding-agent piConfig.name to overcast in node_modules, affecting downstream agent branding/config without explicit user action.
Mechanism
postinstall AI-agent package.json mutation
Policy narrative
On installation, npm runs scripts/brand-pi.mjs. The script locates @earendil-works/pi-coding-agent in node_modules via filesystem traversal or require resolution, parses its package.json, sets piConfig.name to overcast, and writes the dependency package.json back. No exfiltration was found, but the install-time mutation targets an AI coding-agent configuration surface without a user-invoked CLI action.

Decision evidence
public snapshotAI identified this as a dangerous AI-agent capability at 88.0% confidence with low false-positive risk.
Evidence for policy risk
- package.json defines postinstall: node scripts/brand-pi.mjs
- scripts/brand-pi.mjs walks node_modules and writes @earendil-works/pi-coding-agent/package.json
- postinstall changes piConfig.name for an AI coding agent dependency without user command
- dist/bin/overcast.js runtime also writes ~/.pi/agent/settings.json quietStartup when launched
Evidence against
- No install-time network, credential harvesting, or exfiltration found
- Network/curl usage is in user-invoked OSINT/media providers and examples
- Shell/child_process execution is tied to CLI provider commands after user invocation
- skills install writes ~/.claude/skills only via explicit overcast skills install command
