Grades are a hygiene check, not a security guarantee.

Claude Code, Skill

secretgate

Local secrets firewall for coding agents. Detects credentials in prompts, file reads and tool output before they are sent to the LLM API, redacts them to stable placeholders, and restores the real values locally when the agent writes them back.

Compatibility: Not stated.

Grade C

One Medium finding. Read the report before installing.

Graded by PlugVetRubric v2

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

SECRETS_PATH_CREDENTIAL

Why this grade

  • SECRETS_PATH_CREDENTIAL Medium

    Mentions a credential store path (~/.ssh, id_rsa, .npmrc, .aws/credentials, credentials.json, .netrc).

    src/cli.ts, line 858 const denied = runHook("pre-tool-use", { hook_event_name: "PreToolUse", cwd: tmpHome, tool_name: "Read", tool_input: { file_path: "~/.ssh/id_rsa" } });

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.
