Grade D
Two or more Medium findings, or a High finding. Only try it in a sandbox.
Not a guarantee. A hygiene check of the source at the commit shown, not a security audit.
Rescanned at commit b28d6bbbf90a, unchanged since the check below.
INSTALL_LIFECYCLE_HOOK SECRETS_PATH_CREDENTIAL
Why this grade
- INSTALL_LIFECYCLE_HOOK Medium
A package install hook (preinstall, install, postinstall or prepare) runs a script.
package.json, line 29
postinstall - SECRETS_PATH_CREDENTIAL Medium
Mentions a credential store path (~/.ssh, id_rsa, .npmrc, .aws/credentials, credentials.json, .netrc).
publish.ps1, line 92
$script:tempNpmUserConfigPath = Join-Path $env:TEMP ("heuristic-mcp-npm-auth-{0}.npmrc" -f ([Guid]::NewGuid().ToString('N')))
Any High, or two or more Medium findings, give D. One Medium gives C. Low findings or a security Note give B. Each code names a finding behind the letter.
Grades are a hygiene check of the source at the commit shown, on the date checked, not a security audit or a guarantee. The free directory grades are automated. Before release, a PlugVet engineer reviews every paid report and any grade we hold back, including all F grades, against the source code and the evidence we quote.
