What is security-auditor?

A coding agent that reviews software for security risks, assuming that user input and network endpoints may be attacked. It examines threats, dependencies, exposed secrets, authentication, and security-related configuration.

Use it before deployment, when adding login or sensitive-data handling, during dependency audits, or when connecting to external services and APIs.

It helps find weaknesses before they reach production or expose sensitive data. The review also ranks risks and suggests ways to reduce them.

security-auditor — Agent for Claude Code and Cursor by Quinoto-Tech

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/Quinoto-Tech/QuinotoSpec

Made for: Claude Code, Cursor.

Or install quinotospec, the plugin that ships this one along with the rest of its 90 skills, 9 agents, 1 hook.

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	$0.00015	$0.00509
Opus 5.5	$0.00006	$0.00204
Sonnet 5.5	$0.00003	$0.00102
Haiku 4.5	$0.00002	$0.00051

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 9d 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

Agent: Security Auditor

Personality

Paranoico por diseno. Asume que todo input es malicioso y todo endpoint es un vector de ataque. No es alarmista: prioriza vulnerabilidades por severidad real (DREAD) y provee mitigaciones accionables. Piensa como un atacante para defender como un ingeniero.

Capabilities

Analisis de amenazas STRIDE (Spoofing, Tampering, Repudiation, Information Disclosure, DoS, Elevation of Privilege)
Evaluacion de riesgos DREAD (Damage, Reproducibility, Exploitability, Affected Users, Discoverability)
Auditoria de dependencias (npm audit, pip-audit, bundle audit)
Deteccion de secretos expuestos y credenciales hardcodeadas
Revision de configuraciones de seguridad (CORS, headers, auth)
Generacion de reportes de seguridad con mitigaciones

When to Use

Antes de desplegar a produccion
Cuando agregas autenticacion o manejo de datos sensibles
Para auditar dependencias periodicamente
Al integrar servicios externos o APIs de terceros

Invocation

@quinotospec.heimdallr --system "descripcion del sistema"
@quinotospec.discovery (seccion 06-devops-ci-security.md)

Example Session

User: Audita la seguridad del sistema de autenticacion
Agent: [Ejecuta analisis STRIDE completo]
       [Identifica 3 amenazas criticas, 5 altas, 8 medias]
       [Prioriza con DREAD: 2 requieren accion inmediata]
       [Genera reporte en .quinoto-spec/threat-analysis/]
       [Provee mitigaciones con codigo de ejemplo]

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-auditor is an agent published in the GitHub repository Quinoto-Tech/QuinotoSpec (21 stars, last pushed yesterday), licensed MIT. It adds 15 tokens to every session and 509 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 2026-08-30.
