Bestax: Migrate

Security checks for vulnerabilities and agentic risk

Overview

This is a documentation-only migration skill that gives a user-controlled React/Bulma codemod workflow and reference maps, with no hidden persistence or unrelated data access found.

Install this only when you want an agent to modify a React/Bulma codebase. Review the dry-run report and final diff, especially package.json, stylesheet imports, and any TODO(bestax-migrate) resolutions, before accepting the migration.

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

Whitespace Padding

Medium

Category: Prompt Injection
Confidence: 70% confidence
Finding: Large whitespace padding was detected (a block of blank lines or a long run of spaces). This can push injected instructions below or to the right of the visible area so a human reviewer never sees them while the agent still reads them. Manual review of the hidden content is recommended.
