Interview Designer

Security checks for vulnerabilities and agentic risk

Overview

This is a markdown-only interview-preparation skill with a coherent purpose and no hidden execution behavior, though its README uses unpinned npx installer commands users should treat cautiously.

Before installing, prefer a pinned and verified installer version if your environment is sensitive. The skill itself appears to be a plain interview-guide template and methodology package; do not paste sensitive candidate data into any agent or tool unless your organization's data-handling rules allow it.

Vulnerability Patterns

Insecure DependenciesIntroduces malicious components through unsafe dependency sources
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

Verify that the package names, publishers, and registry URLs correspond to the official projects before recommending execution. 3. Document the expected package integrity hashes or signature-verification process where the package ecosystem supports them. 4. Prefer a dependency installation workflow backed by a committed lockfile and integrity metadata when integrating these tools into automated environments. 5. In security-sensitive environments, download and inspect the resolved package and dependency tree before executing it. 6. Run installation under a dedicated, least-privileged account or isolated environment with no unnecessary credentials, sensitive environment variables, or write access to unrelated files. 7. Establish a version-update process in which newer installer releases are reviewed and tested before the pinned version is changed. ]]>

Rp1

Medium

Category: MCP Rug Pull
Confidence: 91% confidence
Finding: The README instructs users to execute npx clawhub@latest install interview-designer, which fetches and runs the latest package version at execution time rather than a reviewed, fixed version. If the upstream package is compromised, typo-squatted, or publishes a malicious update, users could execute attacker-controlled code during installation.

Rp1

Medium

Category: MCP Rug Pull
Confidence: 84% confidence
Finding: The command npx skills add mikonos/interview-designer invokes an unpinned package resolver, so the package/tool actually executed can change over time outside the author's control. This creates a supply-chain risk: a compromised upstream package or malicious newly published version could run arbitrary code on the user's machine during install.
