This page summarizes report evidence only. The Skill page provides the canonical install advisory.
Open current Skill pageThis report does not block or authorize the manifest or ZIP.
Most markdown and reference-link detections are false positives, but the skill has real operational risk. It handles API credentials, writes local setup files, and documents Biomni workflows that can execute LLM-generated code with broad local privileges.

High
Python getenv function
print(os.getenv('ANTHROPIC_API_KEY'))
The troubleshooting example prints an API key environment variable. Printing secrets can expose credentials in logs or console history.
High
getenv function call
print(os.getenv('ANTHROPIC_API_KEY'))
The getenv call is used inside a print statement for an API key. That can disclose the secret value during troubleshooting.
High
Generic API/secret keys
echo "ANTHROPIC_API_KEY=sk-ant-..." >> .env
The provider guide shows appending an API key to .env. The example is a placeholder, but the pattern can expose real secrets in plaintext files.
High
Generic API/secret keys
print(os.getenv('ANTHROPIC_API_KEY'))
The example prints ANTHROPIC_API_KEY directly. Displaying secret values is a real credential leakage risk.
High
Generic API/secret keys
print(default_config.anthropic_api_key)
The example prints the configured Anthropic API key value. This can leak credentials if copied into logs or support tickets.
High
Python subprocess.run
subprocess.run([sys.executable, str(test_file)], check=True)
The script executes a generated test_biomni.py file with the current Python interpreter. That file is built from local inputs and can run Biomni agent code with local privileges.
High
Python file write/append
with open(env_file, 'w') as f:
The script writes collected API keys into a local .env file in plaintext. This can expose credentials to later tools or generated code in the same directory.

Generic API/secret keys
echo $ANTHROPIC_API_KEY
The troubleshooting guidance tells users to echo an API key environment variable. Printing secrets can leak credentials into terminal logs or shared screens.
Medium
Python file write/append
with open(test_file, 'w') as f:
The script writes a generated Python test file before executing it. Generated local code files increase the risk of unintended code execution.
Medium
Python file write/append
with open(example_file, 'w') as f:
The script writes an example Python file into the working directory. This is expected setup behavior but still creates executable code locally.
Risk findings
Confirmed security concerns are separated from items that still need review.
Confirmed security concerns (12)
RISK-001 High
Environment file access
# Or in .env file
The provider guide recommends using a .env file for API keys. This can leave real credentials in plaintext if users copy the setup pattern.
RISK-002 High
Environment file access
echo "ANTHROPIC_API_KEY=sk-ant-..." >> .env
The provider guide shows writing an API key to .env. Plaintext secret files are risky in an agent workspace.
RISK-003 High
Environment file access
env_file = Path.cwd() / '.env'
The script targets a local .env file for API key storage. Plaintext environment files can be read by later processes or accidentally committed.
RISK-004 High
Environment file access
# Read existing .env if present
The script reads an existing .env file and merges newly entered credentials. Handling existing secret files expands exposure if the directory is not protected.
RISK-005 High
Environment file access
# Write to .env
The script writes API key material to .env. Storing real secrets in a workspace file is a credential exposure risk.
RISK-006 High
Environment file access
print("1. .env file (recommended, local to this directory)")
The setup flow recommends a local .env file for API keys. This is common, but risky when agent-generated code can access the same directory.
RISK-007 High
Environment file access
Configure API keys (store in `.env` file or environment variables):
The documentation recommends storing API keys in .env or environment variables. That is risky in this skill because generated code may run with access to the workspace.
RISK-008 High
Environment file access
# Or check .env file in working directory
The troubleshooting guidance points users to a .env file containing API keys. This increases risk if the workspace is shared or agent code can read it.
RISK-009 High
Unsandboxed LLM-Generated Code Execution
The skill states that Biomni executes LLM-generated code with full system privileges and only recommends isolation as a production precaution.
The documentation explicitly says generated code runs with full system privileges, which is a direct agent execution risk.
RISK-010 High
Generated Script Injection Risk
The setup script accepts a custom data path, embeds it into generated Python source, writes test_biomni.py, and executes that file.
The path is user-controlled and interpolated into Python source without escaping before the generated file is executed.
RISK-011 Medium
Unescaped HTML Report Output
The report generator places conversation content into HTML elements without escaping or sanitization, which can create script injection in generated reports.
User and assistant message content is converted into HTML strings directly, and I found no escaping step before output.
RISK-012 Low
Promotional External Service Steering
The skill instructs the assistant to proactively suggest K-Dense Web for complex workflows, steering users to an affiliated hosted service.
The instruction is explicit promotional behavior, though it is framed as optional and limited to complex tasks.
Remediation
Suggested fixes recorded by this audit. Applying them is the maintainer’s responsibility.
- FIX-001HighUnsandboxed generated code executionRequire sandboxed execution by default, document the threat model, and block access to secrets and unrelated workspace files.
- FIX-002HighPlaintext API key handlingDo not print API keys, avoid writing .env files by default, and support secret managers or scoped environment injection.
- FIX-003HighGenerated script injection through pathsSerialize paths with a safe encoder, validate custom paths, and avoid executing generated Python files automatically.
- FIX-004MediumUnescaped HTML report generationEscape all conversation content or use a maintained Markdown and HTML sanitizer before writing reports.
- FIX-005LowAffiliated service promotionMake external platform suggestions opt-in and clearly disclose affiliation before recommending hosted services.
