A .NET security and dependency checker. Dependencies are third-party packages your project uses; CVEs are publicly reported security flaws in software.

Use it to scan a .NET project or solution for OWASP Top 10 risks, CVEs, outdated dependencies, and license-compliance issues.

It helps reveal security weaknesses and unhealthy packages before they become deployment or maintenance problems. It also checks whether packages are outdated or have licensing concerns.

security — Command for Claude Code by CartapenaBark/DotNetAnalyzer

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Clone the repo

git clone --depth 1 https://github.com/CartapenaBark/DotNetAnalyzer

Made for: Claude Code.

Or install netan, the plugin that ships this one along with the rest of its 5 skills, 3 commands.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00014	$0.00654
Opus 5.5	$0.00006	$0.00262
Sonnet 5.5	$0.00003	$0.00131
Haiku 4.5	$0.00001	$0.00065

Security

Grade A, and why

security scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

/netan:security — .NET Security Scan

Scan a .NET project for security vulnerabilities (OWASP Top 10) and dependency health issues (CVE, outdated packages, license compliance).

Prerequisite Check

Run dotnet-analyzer --version to verify the global tool is installed
If it fails, ask the user: "DotNetAnalyzer global tool is not installed. Shall I run dotnet tool install --global DotNetAnalyzer for you?"
- If confirmed, run dotnet tool install --global DotNetAnalyzer and continue
- If declined, provide the manual install command and stop

Arguments

The user may optionally provide a project or solution path:

If provided: use that path directly
If not provided: auto-detect by looking for *.slnx or *.sln in the current working directory
If no solution file found: ask the user for the path

Steps

Identify the target:
- Use the provided path, or auto-detect *.slnx / *.sln in the current directory
- Prefer solution file for comprehensive scanning
Scan security vulnerabilities:
- Call scan_security_vulnerabilities with the project path
- Use minimum severity Medium (default) unless user specifies otherwise
Scan dependency health:
- Call scan_dependencies_health with the project path
- Note overall health score, outdated packages, deprecated packages
Check license compliance:
- Call check_license_compliance with the project path
- Report any non-compliant packages

Present findings grouped by severity:

## Security Scan: [Project/Solution Name]

### Overview
- Total findings: N
- Critical: N | High: N | Medium: N | Low: N

### Critical / High Severity
| Rule | Finding | File | Fix |
|------|---------|------|-----|
| SEC001 | Hardcoded credential | ... | ... |

### Medium Severity
| Rule | Finding | File | Fix |
|------|---------|------|-----|
| ... | ... | ... | ... |

### Dependency Health
- Health Score: N/100
- Outdated: N packages
- Vulnerable: N packages
- Deprecated: N packages

### License Issues
- Non-compliant: N packages
| Package | License | Issue |
|---------|---------|-------|
| ... | GPL-3.0 | Not in whitelist |

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

security is a command published in the GitHub repository CartapenaBark/DotNetAnalyzer (2 stars, last pushed 6mo ago), licensed MIT. It adds 14 tokens to every session and 654 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
