AI Security Review

scanned 11d ago · by lpm-firewall-ai

Source inspection shows agent configuration capabilities connected to explicit commands and limited maintenance during ingest, so this warrants a warning for agent capability risk. The install hook only copies a project guidance file and does not establish an unconsented control-surface attack.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review; previous stored version diff introduced dangerous source

Trigger

A user runs practice sync or the hooks install command; ingest may refresh files Koragraph already manages.

Impact

These changes affect later agent sessions and can deliver stored project guidance or run Koragraph hooks.

Mechanism

The sync code writes rulebook content to agent files, while the hooks command adds Koragraph command entries to Claude settings.

AI rationale

Evidence

src/practice/sync.jssrc/services/practice-hooks.jssrc/cli/hooks.jssrc/cli/ingest.js

Decision evidence

public snapshot

AI called this Suspicious at 87.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

The postinstall hook only copies KORAINIT.md into the invoking project when the file is absent.
The package can write generated rulebook content into supported agent instruction files during practice sync.
Ingest refreshes only agent files Koragraph already manages; it does not create new ones.
The hooks command installs Claude session hooks when its install verb is selected.

Evidence against

The lifecycle hook skips global installs and does not configure agent hooks or execute a downloaded payload.
Claude hook installation is invoked through the hooks command’s install path, and existing settings are preserved.
