Not a guarantee. A hygiene check of the source at the commit shown, not a security audit.

PERMISSION_DELETE_FILES SECRETS_PATH_DOTENV OBFUSCATION_FILE_CAP_REACHED

Why this grade

  • PERMISSION_DELETE_FILES Low

    Contains a call that can delete files.

    npm/index.js, line 72 fs.rmSync(oldCacheDir, { recursive: true, force: true });

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    .gitignore, line 40 .env

  • OBFUSCATION_FILE_CAP_REACHED Note

    The 400 file cap was reached before every file was read.

    org.javalens.mcp.tests/src/org/javalens/mcp/tools/analysis/AnalyzeFileCompactSourceTest.java, line 1 package org.javalens.mcp.tools.analysis;

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.
