moflo@4.12.5

MoFlo — AI agent orchestration for Claude Code. A standalone, opinionated toolkit with semantic memory, learned routing, gates, spells, and the /flo issue-execution skill.

AI Security Review

scanned 5d ago · by lpm-firewall-ai

LPM flags this version as an AI-agent control-surface risk. On npm postinstall, the package mutates an existing Claude Code control surface. It installs a broad set of launchers, hooks, helpers, and supporting libraries into the consumer project.

Static reason

One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review

Trigger

npm installation or upgrade in a project that already contains .claude/

Impact

Unconsented replacement or addition of executable Claude Code hook, launcher, and helper code in the consumer project.

Mechanism

postinstall bootstrap copies package-controlled agent scripts and helpers into consumer .claude paths

Policy narrative

Installing moflo invokes postinstall. When the consumer already has .claude/, the bootstrap creates and atomically copies package-selected scripts, all bin/lib files, migrations, and helpers into that foreign agent-control directory. The manifest includes session-start, hook, prompt-hook, and automation components, so the mutation can affect future Claude Code execution without an explicit setup command.

Rationale

This is a concrete, unconsented npm postinstall mutation of a pre-existing foreign AI-agent control surface. The guards and absence of observed exfiltration do not remove the broad automatic control-surface write.
