Project Skeletonization

Security checks for vulnerabilities and agentic risk

Overview

This skill is a plain Markdown workflow for turning a project into a reusable skeleton, and its file-changing behavior is disclosed, purpose-aligned, and gated on user confirmation.

Install this only when you intend to let an agent inspect and modify a project to remove business-specific functionality. Before approving a transformation plan, review the proposed keep/remove lists carefully, especially database migrations, authentication, scheduled jobs, file storage, audit logs, and deployment configuration.

A.I.G

Vulnerability Patterns
  • Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
  • Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs

Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.

Convert an existing complete business project into a reusable base skeleton. The skeleton should run independently, keep common engineering capabilities, remove concrete business features, and provide minimal placeholder pages, APIs, or tasks to prove that the framework path still works.

This skill is collaborative. Do not perform large deletions or refactors without confirmation. If module ownership, retention policy, or future reuse direction is unclear, ask the user first.
