llm-wiki-loop@1.1.0

The reference architecture for LLM-maintained knowledge vaults ??schema, lifecycle loop, machine verification, self-installation. Installs the wiki-manager skill into your agent runtime (Claude Code, Codex CLI, opencode).

AI Security Review

scanned 3h ago · by lpm-firewall-ai

LPM flags this version as an AI-agent control-surface risk. npm postinstall automatically copies a skill into detected AI-agent runtime directories. It force-overwrites the destination and activates after the runtime restarts.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review

Trigger

npm installation; global installs target home runtimes, while project installs target existing project agent directories.

Impact

Mutates broad foreign agent control surfaces and can change agent behavior without an explicit user command.

Mechanism

unconsented install-time AI-agent skill deployment

Policy narrative

Installing the package runs scripts/install.js automatically. The script detects multiple third-party agent runtimes and copies the bundled wiki-manager skill into each detected global or project runtime directory; copying is recursive and forced. This is an unconsented postinstall mutation of broad AI-agent control surfaces, even though the inspected payload contains no network or credential-exfiltration behavior.

Rationale

The package’s postinstall deploys and force-overwrites behavior-bearing skills across unrelated agent runtimes without an explicit user command. This meets the install-control-surface block condition.
