AI Security Review

scanned 20d ago · by lpm-firewall-ai

LPM treats this as warn-only first-party agent extension lifecycle risk. This package is a first-party Elyntic/Helios agent product. npm install runs a native-binding hook, the manifest loads bundled Pi extensions, and later product commands can start a daemon, write channel tokens, and upgrade the coding agent globally. Those behaviors match the stated product, but the tree is too large for complete static coverage, so dual-use residual risk remains.

Static reason

High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source

Trigger

npm install of @cgh567/agent, then running the Elyntic CLI, a Pi session, the company daemon, or the upgrade-review command

Impact

A consumer who installs and uses this product gets native binaries, a local daemon, credential files, and agent-host extensions. Inspected source does not show stealth theft to an attacker-owned host.

Mechanism

first-party Pi extension load, postinstall native staging, and runtime daemon or agent process control

AI rationale

Inspected source shows a first-party Helios/Pi agent product with an install-time native-binding hook and bundled extensions, not a hidden foreign-agent hijack or self-install malware chain. The package is too large for complete static coverage and still contains dual-use daemon spawn, token file writes, and global npm upgrades, so it should warn rather than be marked clean or blocked.

Evidence

package.jsonpostinstall.cjsextensions/upgrade-reviewer.tsdaemon/daemon-manager.jsdaemon/lib/wizard-engine.jsdaemon/routes/channels.jsbin/elyntic-ollama-models.cjsprebuilds/

Decision evidence

public snapshot

AI called this Suspicious at 68.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

Automatic postinstall copies a native SQLite binding and can spawn extra setup scripts after npm install.
The manifest registers first-party Pi extensions and skills for the coding-agent host.
The upgrade reviewer can run a global npm install of the coding-agent package.
The daemon manager starts a detached background company daemon.
The company wizard forks a detached headless RPC child that loads the full extension set.
Channel setup writes Slack bot tokens to a local config file.

Evidence against

There is no runtime dependency on @cgh567/agent, so no nested self-install lifecycle chain.
postinstall.cjs stages Ladybug and better-sqlite3 native files; it does not write Claude, Cursor, or other foreign agent configs.
Token writes and daemon or RPC spawns are product setup after the user runs Elyntic, not a hidden install-time hijack.
The node -e helper in bin/elyntic-ollama-models.cjs only queries local Ollama /api/tags.
The flagged Unicode in metadata-recompute.ts is a UTF-8 BOM around iMessage metadata math, not a hidden bidi payload.
README and the GitHub repo describe the same Helios/Pi multi-agent product the code implements.
