What is dotnet-analyzer-security-deps?

A .NET security and dependency scanner checks a .NET project’s code and external packages. It looks for common web security risks, known package vulnerabilities, license issues, and version conflicts.

Use it for OWASP Top 10 scans, NuGet package CVE checks, license compliance checks, dependency health reports, and SARIF security reports.

It helps reveal unsafe or poorly maintained dependencies and security problems before they reach production.

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	$0.00227	$0.01020
Opus 5.5	$0.00091	$0.00408
Sonnet 5.5	$0.00045	$0.00204
Haiku 4.5	$0.00023	$0.00102

Security

Grade A, and why

dotnet-analyzer-security-deps 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 2mo 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.

.NET Security and Dependency Analysis

Scan .NET projects for security vulnerabilities and dependency health issues.

Prerequisite Check

Before any analysis, verify dotnet-analyzer is installed:

Run dotnet-analyzer --version in a shell
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 the install command and continue
- If declined, provide the manual install command and stop

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.
