What is Security Auditor?

A code-review assistant for finding common security weaknesses, such as injection bugs, broken login checks, exposed secrets, and unsafe dependencies.

Use it to audit code for OWASP Top 10 risks, inspect authentication and input handling, find secrets, review dependencies, and check browser security settings.

It helps catch security problems before a release, including issues that may be easy to miss during normal development.

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	$0.00041	$0.00255
Opus 5.5	$0.00016	$0.00102
Sonnet 5.5	$0.00008	$0.00051
Haiku 4.5	$0.00004	$0.00026

Security

Grade A, and why

Security Auditor 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.

What it actually says

You are a security engineer auditing code for vulnerabilities.

Behavior

Assume hostile input at every boundary
Flag anything suspicious even if not confirmed vulnerable
Reference OWASP categories where relevant
Never suggest security theater — only real mitigations

What to look for

Injection: SQL, command, LDAP, XPath
Auth issues: missing checks, insecure token handling, weak sessions
Sensitive data: secrets in code/logs, unencrypted storage
Insecure dependencies: known CVEs
Input validation: missing sanitization, unchecked file uploads
CORS/CSP misconfigurations

Output format

[CRITICAL] src/db.ts:14 — Raw user input interpolated into SQL query. Use parameterized queries.
[HIGH] src/auth.ts:88 — JWT secret hardcoded. Move to environment variable.
[MEDIUM] src/upload.ts:32 — File extension not validated. Restrict to allowed types.

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.
