Expected outputs
Key source sections
Sections are extracted automatically from the pinned SKILL.md and link back to the source.
Implementar autenticación o autorización
Comenzar con una política estricta y relajarla solo con un plan de eliminación documentado. No usar 'unsafe-inline' ni 'unsafe-eval' por defecto; neutralizan gran parte de la protección de CSP y deben tratarse como deuda de compatibilidad temporal.
[ ] Sin claves de API, tokens ni contraseñas hardcodeadas
Review the “FALLA: NUNCA Hacer Esto” section in the pinned source before continuing.
Review the “PASA: SIEMPRE Hacer Esto” section in the pinned source before continuing.
SkillSignal prompt templates
These prompts were written by SkillSignal from the source structure; they are not upstream text.
Task-start prompt
Confirm source fit, inputs, and outputs before acting.
Use security-review to help me with: [specific task]. Context: [files, data, or background]. Constraints: [environment, scope, and prohibited actions]. Before acting, check the pinned SKILL.md and explain which sections apply, what inputs are still missing, and what you will deliver.
Source-guided execution
Make the Agent explicitly follow the key extracted sections.
Apply the pinned security-review source to [task]. Pay particular attention to these source sections: “Cuándo Activar”, “Lista de Verificación de Seguridad”, “1. Gestión de Secretos”, “FALLA: NUNCA Hacer Esto”, “PASA: SIEMPRE Hacer Esto”. Preserve the important decision at each step. Mark facts not covered by the source as “needs confirmation” instead of inventing them. Then verify the result against my acceptance criteria: [criteria].
Result-review prompt
Check omissions, permissions, and source drift before delivery.
Review the current security-review result: (1) does it satisfy the original task; (2) were any applicable steps or limits in the pinned SKILL.md missed; (3) did it perform any unauthorized file, command, network, or data action; and (4) which conclusions remain unverified? List issues first, then fix only what the source or user authorization supports.
Output checklist
The task matches the purpose documented in the SKILL.md.
The source section “Cuándo Activar” has been checked.
The source section “Lista de Verificación de Seguridad” has been checked.
The source section “1. Gestión de Secretos” has been checked.
The source section “FALLA: NUNCA Hacer Esto” has been checked.
Inputs, constraints, and acceptance criteria are explicit.
Unverified facts, compatibility, and outcome claims are clearly marked.
Any file, command, network, or data action has been reviewed.

Antes de CUALQUIER despliegue a producción:
Recuerda: La seguridad no es opcional. Una sola vulnerabilidad puede comprometer toda la plataforma. Ante la duda, optar por el lado de la precaución.
