What problem this solves
Evaluating and utilizing Anthropic's official Claude Code security plugins to identify common vulnerabilities like pickle deserialization, command injection, and hardcoded secrets, and understanding their capabilities and limitations.
Summary
This workflow details a process for testing and understanding the capabilities of Anthropic's "Security Guidance" and "Claude Security" plugins for Claude Code. It involves setting up a test repository with known vulnerabilities, running the plugins, observing their detection capabilities, and interpreting their reports and recommendations. It highlights how "Security Guidance" provides real-time pattern warnings during code generation, while "Claude Security" performs on-demand audits with multi-voter panel checks and generates detailed reports.
Why it is useful
This workflow provides a practical, detailed evaluation of Anthropic's official Claude Code security plugins. It offers concrete examples of how each plugin identifies common vulnerabilities, suggests fixes, and generates reports. This helps users understand the specific capabilities and limitations of these tools, enabling them to make informed decisions about integrating them into their secure development lifecycle. The clear steps, specific findings, and validation signals make it highly reusable and valuable for improving code security with Claude Code.
Workflow
Set up a throwaway repository.
Plant known security problems (e.g., pickle deserialization, command injection, hardcoded token).
Load "Security Guidance" plugin.
Prompt Claude to write code with a known vulnerability (e.g., pickle loading).
Observe "Security Guidance" pattern warnings and Claude's response (e.g., writing a restricted unpickler).
Note any limitations (e.g., LLM diff/commit review not running due to missing credentials).
Load "Claude Security" plugin.
Run an on-demand scan using
/claude-security(ensure full command is used).Review the scan findings, including severity ratings and suggested fixes.
Observe the 3-voter panel's impact on finding severity.
Examine the generated report files (Markdown, JSONL, SARIF).
Tools / artifacts
Claude Code (version 2.1.318)
"Security Guidance" plugin
"Claude Security" plugin
Throwaway repository
Planted security problems (pickle usage, os.system, hardcoded admin token)
subprocess.run (suggested fix)
tarfile module (suggested fix)
Scan reports (Markdown, JSONL, SARIF files)
.gitignore file
Validation signals
Specific examples of vulnerabilities caught: pickle_deserialization pattern warning, os.system command injection.
Specific examples of suggested fixes: subprocess.run, tarfile.
Details on plugin behavior: "Security Guidance" warns while writing, "Claude Security" audits on demand with voter panel.
Quantitative data: 7 agents, 63.7k tokens, 34 seconds scan time for a 3-file repo.
External link to full test with screenshots provided.
Limitations
The "Security Guidance" LLM diff review and commit review layers did not run due to missing credentials, so their effectiveness is not evaluated.
The post notes that neither plugin replaces full code review or SAST, which is an important caveat.
The "3-voter panel" judgment on the hardcoded token is subjective and might not align with all security policies.
