use-native-credential-proxy
Opt out of the OneCLI gateway and supply Anthropic credentials from .env instead. For users who want simple .env-based credential management without the OneCLI agent vault. Reads the API key or OAuth token from .env and injects it into the container's API requests.

3 findings: 1 critical severity, 1 high severity, 1 medium severity. Installing this skill is not recommended: please review these findings carefully if you do intend to do so.
E006: Malicious code pattern detected in skill scripts.
What this means
Detected high-risk code patterns in the skill content — including its prompts, tool definitions, and resources — such as data exfiltration, backdoors, remote code execution, credential theft, system compromise, supply chain attacks, and obfuscation techniques.
Why it was flagged
This skill intentionally bypasses the OneCLI vault and threads plaintext Anthropic credentials from a host .env into container environment variables, a deliberate insecure design that enables credential exposure and makes exfiltration or misuse by the container trivial if the container or its network is compromised.
W007: Insecure credential handling detected in skill instructions.
What this means
The skill handles credentials insecurely by requiring the agent to include secret values verbatim in its generated output. This exposes credentials in the agent’s context and conversation history, creating a risk of data exfiltration.
Why it was flagged
This skill explicitly reads secrets from a host .env and constructs Docker -e VAR=value arguments (and instructs users to echo tokens/keys into .env), which requires the agent/code to handle and potentially emit secret values verbatim into container args or logs, creating an exfiltration risk.
W013: Attempt to modify system services in skill instructions.
What this means
The skill prompts the agent to compromise the security or integrity of the user’s machine by modifying system-level services or configurations, such as obtaining elevated privileges, altering startup scripts, or changing system-wide settings.
Why it was flagged
This skill explicitly instructs bypassing the OneCLI gateway by moving live Anthropic credentials into a host .env and injecting them into container envs (via code edits and .env writes), which is a deliberate security bypass that compromises credential handling on the machine.
