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

Rescanned at commit cf6895cbdd2e, unchanged since the check below.

PERMISSION_DELETE_FILES NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV SECRETS_ENV_READ

Why this grade

  • PERMISSION_DELETE_FILES Low

    Contains a call that can delete files.

    src/recall/git_sync.py, line 39 proc = subprocess.run(

  • NETWORK_NO_FIXED_HOST Low

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

    clients/typescript/src/client.ts, line 15 /** Custom fetch (for testing). Defaults to global fetch. */

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    src/recall/config.py, line 5 Azure-specific paths. Operators override via env vars or .env file.

  • SECRETS_ENV_READ Note

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

    examples/python/agent_memory.py, line 19 KEY = os.environ.get("RECALL_KEY", "changeme")

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.
