oh-langfuse@1.2.2

Use npm scripts to configure Claude Code / OpenCode / Codex / DeepSeek Harness with Langfuse tracing.

AI Security Review

scanned 10d ago · by lpm-firewall-ai

The manifest has no npm install lifecycle hook, and the inspected agent configuration changes are reached through explicit setup commands. The scanner’s execution and network signals are consistent with setup and update functionality; the inspected source did not establish malicious behavior.

Static reason

One or more suspicious static signals were detected.

Trigger

A user invokes an agent setup or update command.

Impact

The inspected behavior configures the requested tracing integration; no confirmed attack surface was established.

Mechanism

Setup writes tracing configuration for the selected agent; the OpenCode setup installs plugin dependencies with install scripts disabled.

AI rationale

Decision evidence

public snapshot

AI called this Clean at 86.0% confidence as Benign with low false-positive risk.

Evidence for AI clean decision

package.json defines setup as an npm command and contains no preinstall, install, or postinstall hook.
bin/cli.js dispatches agent configuration changes through explicit setup commands.
The Codex and Claude setup files write to their respective user configuration directories; the OpenCode setup installs plugin dependencies with lifecycle scripts disabled.
The update script queries npm registry metadata and invokes local package scripts.
