Adversarial Testing — 4 categories, 4 findings

prompt injection chainscapability squattingcontext poisoningdependency confusion
highWarnprompt injection chainssuspected

Several agents in this skill (api-designer, backend-developer, electron-pro, frontend-developer, fullstack-developer) are designed to process user requirements, files, and specifications without clear data boundary markers. The agents reference 'business requirements', 'client requirements', 'user specifications' and similar user-provided content that could contain instruction-like directives. While the agents have structured workflows, there are no explicit safeguards preventing user content from being interpreted as overriding instructions.

highWarnprompt injection chainsconfirmed

Multiple agents have 'Bash' tool access and are designed to execute commands based on user requirements. The backend-developer agent specifically mentions 'Migration scripts and version control', 'Container images built', and other operations that could involve shell execution. The electron-pro agent references 'Build configuration', 'Native dependency handling', and 'CI/CD integration' which could involve shell commands. User-provided project names, file paths, or configuration values could potentially inject additional shell parameters or commands.

highWarncontext poisoningconfirmed

The skill contains numerous 'always' directives that establish persistent behavioral patterns without explicit termination or scope boundaries. These directives would affect the agent's behavior on unrelated tasks beyond the skill's declared backend development purpose.

highWarncontext poisoningconfirmed

The backend-developer skill (stated purpose: server-side APIs and backend systems) contains extensive directives for frontend development, desktop application development, API design, and cross-platform distribution. This represents significant scope creep beyond the declared backend development domain.
