Confirmed finding summary

No confirmed security findings

The completed audit recorded no confirmed security findings. This is not proof that the Skill has no side effects.

Installation context

Historical evidence

This report may not describe the currently installable artifact. Open the current Skill page for install guidance.

This report does not block or authorize the manifest or ZIP.

This skill provides documentation and helper scripts for the biomni biomedical AI framework. The setup script runs external commands (conda) and writes API keys to .env files, which are legitimate setup operations but expand the attack surface. No evidence of obfuscation, credential theft, or malicious network calls.

Capability review items (2)
Medium
scripts/setup_environment.py:67-69scripts/setup_environment.py:218-219
Setup script runs external commands
The setup script executes external binaries and a generated test script using subprocess.run(). Example from line 67-69: "subprocess.run(['conda', 'create', '-n', 'biomni_e1', 'python=3.10', '-y'], check=True)". If a malicious binary is earlier in PATH, an attacker could run arbitrary code under the user account. This is a standard setup pattern but requires PATH hygiene.
Low
scripts/setup_environment.py:145-149
API keys saved in plaintext .env
API keys are written to disk in plaintext format. From lines 145-149: "with open(env_file, 'w') as f:" followed by "f.write(f\"{key}={value}\\n\")". If the directory is shared, backed up insecurely, or accessed by other users, credentials could be exposed. Users should set restrictive file permissions (chmod 600) on .env files.
