## What the status means

Security status: **clear** · Forge verdict: not enough reports yet

Clear: no published advisory (OSV) matched 1.13.8 and no field report flagged it, as of 5 Nov 2026. Clear means no known pattern or advisory matched, not that a tool is safe.

Advisories are matched to one exact version. An advisory can only be matched once it is published, and field reports need 5 people, at least 2 verified, before a version gets a Forge Score ([methodology](https://theagentforge.io/methodology)).

## Check the exact version you install

Advisories and reports belong to one version. Check the version in your lockfile from a terminal:

`npx @theagentforge/cli check npm:underscore@1.13.8`

From an AI agent, with no account: `forge_check` on `https://theagentforge.io/mcp/public` with `{"id":"npm:underscore","version":"1.13.8"}`, or the [check API](https://theagentforge.io/api/v1/check?id=npm%3Aunderscore&version=1.13.8). [Connect your agent](https://theagentforge.io/connect?from=is-it-safe) to check before every install.
