Grades are a hygiene check, not a security guarantee.

Claude Code, Skill

Codex Red

Offensive-security skills adapted for the OpenAI Codex skill system.

Compatibility: Not stated.

Grade D

Two or more Medium findings, or a High. Only try it in a sandbox.

Graded by PlugVetRubric v2

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

INSTALL_REMOTE_SCRIPT AGENT_IGNORE_INSTRUCTIONS OBFUSCATION_RUNS_ENCODED_PAYLOAD SECRETS_PATH_CREDENTIAL

Why this grade

  • INSTALL_REMOTE_SCRIPT High

    Fetches a script from the network and runs it (a pipe to a shell, or an install hook with a URL).

    Skills/exploit-dev/offensive-exploit-dev-course/SKILL.md, line 29 curl --proto '=https' --tlsv1.2 -sSf "https://sh.rustup.rs" | sh

  • AGENT_IGNORE_INSTRUCTIONS High

    Text tells the agent to ignore earlier instructions.

    Skills/ai/offensive-ai-security/SKILL.md, line 76 - **Direct Injection**: Craft prompts that instruct the LLM to ignore previous instructions, reveal its system prompt, or perform unauthorized actions.

  • OBFUSCATION_RUNS_ENCODED_PAYLOAD High

    Decodes and runs an encoded payload (for example eval with atob or base64).

    Skills/exploit-dev/offensive-basic-exploitation/SKILL.md, line 1 ---

  • SECRETS_PATH_CREDENTIAL Medium

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

    Skills/cicd/offensive-cicd-pipeline/SKILL.md, line 362 cat /home/*/.aws/credentials 2>/dev/null

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.

If you think this grade is wrong, email [email protected] with the entry link and your evidence. We aim to acknowledge within two working days and decide within seven. If we confirm an error, we aim to correct it within 24 hours of confirming it. These are aims, not guarantees.

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.

  • Install and update
