Your agents remember what you decided and what you changed — from a folder of Markdown you own (open it in Obsidian if you like), with the source of every answer, and "not in the vault" instead of a guess.

Compatibility: Not stated.

Grade B

Minor issues only, no Medium or High. Worth a quick look at the findings below before installing.

Graded by PlugVetRubric v2

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

PERMISSION_DELETE_FILES INSTALL_UNPINNED NETWORK_NO_FIXED_HOST NETWORK_UNNAMED_HOST SECRETS_PATH_DOTENV INSTALL_DOCUMENTED_INSTALLER SECRETS_ENV_READ OBFUSCATION_FILE_CAP_REACHED

Why this grade

  • PERMISSION_DELETE_FILES Low

    Contains a call that can delete files.

    bench/longmemeval/lme.py, line 56 shutil.rmtree(vaults)

  • INSTALL_UNPINNED Low

    Dependencies use a range or git URL with no lockfile.

    README.md, line 21 curl -fsSL https://raw.githubusercontent.com/398894496-arch/KRouter/main/scripts/bootstrap.sh | sh

  • NETWORK_NO_FIXED_HOST Low

    Makes a network call whose host is not written as a fixed address.

    bench/memory_honesty/adapters/claude_mem.py, line 50 with urllib.request.urlopen(url, timeout=120) as resp:

  • NETWORK_UNNAMED_HOST Low

    Calls a fixed host that the description does not name.

    bench/memory_honesty/adapters/claude_mem.py, line 50 with urllib.request.urlopen(url, timeout=120) as resp:

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    .gitignore, line 2 .env

  • INSTALL_DOCUMENTED_INSTALLER Note

    Documentation shows an installer that pipes a download into a shell.

    README.md, line 21 curl -fsSL https://raw.githubusercontent.com/398894496-arch/KRouter/main/scripts/bootstrap.sh | sh

  • SECRETS_ENV_READ Note

    Reads an environment variable whose name contains KEY, SECRET, TOKEN, PASSWORD or CREDENTIAL.

    bench/real_questions/classify_asks.py, line 74 headers={"Authorization": "Bearer " + os.environ.get("KROUTER_EVAL_KEY", ""),

  • OBFUSCATION_FILE_CAP_REACHED Note

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

    tests/test_unconfined_optin.py, line 1 """A CLI KRouter cannot confine is never picked on its own: only grok and claude are used without asking.

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.
