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Use it to scan a .NET project or solution for OWASP Top 10 risks, CVEs, outdated dependencies, and license-compliance issues.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 It also checks whether packages are outdated or have licensing concerns.

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

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

Per session 14 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.

When invoked 654 The whole file, excluding the scripts and references it only reads on demand.

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	$0.00014	$0.00654
Opus 5	$0.00007	$0.00327
Sonnet 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 2d 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Scan a .NET project for security vulnerabilities (OWASP Top 10) and dependency health issues (CVE, outdated packages, license compliance).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

### 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 |

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.
