@netnodeag/kraftwerk@0.17.3
Deterministic workflow-as-code framework: agents (persona + model + tools + harness) run in bounded phases on headless CLI harnesses (claude -p, codex exec, pi); code owns the control flow, envelopes + gates judge the results
AI Security Review
scanned 2mo ago · by lpm-firewall-aiNo concrete malicious install or exfiltration chain was found, but the package intentionally provides high-impact agent execution with unattended permission approval. Static analysis coverage was incomplete, so this should be warned rather than marked clean.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
A user configures or starts a workflow, inspector routine, remote source, MCP server, or sandbox run.
Impact
A malicious or unsafe workflow could perform actions available to the configured agent, MCP server, credentials, or SSH agent.
Mechanism
Launches local agent CLIs and workflow-controlled tools with optional automatic approval.
AI rationale
No concrete malicious install or exfiltration chain was found, but the package intentionally provides high-impact agent execution with unattended permission approval. Static analysis coverage was incomplete, so this should be warned rather than marked clean.

Decision evidence
public snapshotAI called this Suspicious at 74.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- Routine team chats automatically choose an allow permission option before invoking a local agent backend.
- The inspector launches `npx kraftwerk run` detached in the consumer project after a UI-triggered run request.
- The optional Docker runner forwards selected API-key environment variables and can mount the SSH agent when requested.
- The Codex harness grants automatic approval when a workflow supplies MCP servers.
- Remote workflow specifications are cloned from user-supplied Git URLs.
Evidence against
- package.json has no preinstall, install, or postinstall hook; its only lifecycle script is prepublishOnly.
- The runtime npm install is limited to building missing inspector assets in a development checkout; published assets are shipped.
- No source inspected sends harvested credentials or local files to a package-controlled endpoint.
- The risky operations require an explicit workflow, UI, sandbox, or remote-source action.
