Bring this context
Expected outputs
Key source sections
Sections are extracted automatically from the pinned SKILL.md and link back to the source.
인증 또는 권한 부여 구현 시
{nonce}는 요청마다 새로 생성하고, 헤더와 인라인 / 태그에 동일하게 주입해야 합니다.
[ ] 하드코딩된 API 키, 토큰, 비밀번호 없음
Review the “절대 하지 말아야 할 것” section in the pinned source before continuing.
Review the “반드시 해야 할 것” 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: “활성화 시점”, “보안 체크리스트”, “1. 시크릿 관리”, “절대 하지 말아야 할 것”, “반드시 해야 할 것”. 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 “활성화 시점” has been checked.
The source section “보안 체크리스트” has been checked.
The source section “1. 시크릿 관리” has been checked.
The source section “절대 하지 말아야 할 것” 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.
