security-review

A security-focused review for ASP.NET Core applications, checking code for common ways an application can be attacked or expose data.

In plain words
What is it for?
Use it to inspect uncommitted changes, or the Api and Data projects when there are no uncommitted changes, and receive a severity-ranked report with suggested fixes.
Why use it?
It helps find risks such as SQL injection, missing access checks, exposed secrets, unsafe input handling, and missing protection for browser-based requests 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.

Security

Grade A, and why

security-review 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.

Origin

This is a copy

100% identical to security-review — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

Perform a security review of $ARGUMENTS (default scope: uncommitted changes, falling back to the whole Api and Data projects if the working tree is clean).

Check for: SQL injection (string building into queries), missing input validation on request models and route/query parameters, authentication/authorization gaps (endpoints missing RequireAuthorization, IDOR patterns), sensitive data exposure (secrets in code/config/logs, EF entities serialized to clients, stack traces in responses), missing rate limiting on write endpoints, CSRF exposure on cookie-authenticated endpoints, and insecure deserialization of external payloads.

Output a structured report:

Severity Location Description Remediation

Severity scale: Critical / High / Medium / Low. After the table, list the categories you checked that came back clean. Do not fix anything — report only.

Changes

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.
