AI Security Review

scanned 15d ago · by lpm-firewall-ai

The postinstall path invokes repair for an existing Codex wrapper and otherwise prints setup guidance; source shows no package-install agent configuration write. Agent integrations require a CLI command, and the scheduler operates on registered Hippo workspaces, so the scanner signals do not establish malicious behavior.

Static reason

One or more suspicious static signals were detected.

Trigger

npm postinstall runs after installation; agent integration writes occur when the user runs Hippo init or an explicit hook-install command.

Impact

The inspected behavior does not establish an unconsented agent control-surface mutation, credential exposure, or malicious persistence.

Mechanism

The postinstall path repairs an existing Codex wrapper and prints setup nudges. CLI setup detects agent files, and scheduled maintenance operates on registered Hippo workspaces.

AI rationale

Decision evidence

public snapshot

AI called this Clean at 91.0% confidence as Benign with low false-positive risk.

Evidence for AI clean decision

package.json runs a postinstall script that imports dist/postinstall.js.
dist/postinstall.js calls a repair routine and prints setup nudges; its comments describe the repair as applying only to an existing opt-in Codex wrapper.
dist/hooks/codex-wrapper.js returns without changes when wrapper metadata is absent.
dist/cli/init.js writes integrations only when the user runs init; it detects agent configuration files before patching.
dist/cli/setup.js installs hooks through an explicit hook-install command.
dist/scheduler.js runs daily maintenance only for registered workspaces containing a .hippo directory.
dist/cli/shared.js validates the runner path before creating a scheduled task.
