Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed AgentPMT interface for querying World Bank education data, with no embedded executable code or hidden local behavior.

Install this only if you want AgentPMT-hosted education-data lookups. Prefer reviewed or pinned installation paths for the related setup skills, and do not send account secrets, wallet keys, payment headers, or unrelated personal data through prompts or tool inputs.

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

### Technical Analysis

The Skill instructs users to execute `npx` and install two additional Skills from `AgentPMT/agent-skills` without pinning the CLI version, repository commit, release tag, or artifact integrity digest. Consequently, the content installed at a future date may differ from the content reviewed when this Skill was audited.

The setup Skills are especially security-sensitive because one is explicitly responsible for AgentPMT account, MCP, and REST configuration. If the upstream repository, package publication process, dependency-resolution infrastructure, or maintainer account is compromised, altered content could be delivered through these documented installation commands.

This is a supply-chain weakness rather than evidence that the currently referenced dependencies are malicious.

Remediation Suggestions

  1. Pin the npx CLI package to a reviewed, exact version rather than allowing resolution of the latest release.
  2. Pin AgentPMT/agent-skills to an immutable commit hash or cryptographically signed release.
  3. Publish and verify SHA-256 or stronger integrity digests for downloaded artifacts before installation.
  4. Require signature verification and fail closed when a signature, version, or digest does not match.
  5. Replace automatic reinstall guidance with an explicit update-and-review process.
  6. Review the downloaded Skill files before activation, particularly any setup component that handles account credentials or connection configuration.
  7. Run installation in a sandbox with restricted filesystem, environment-variable, credential-store, and network access.
  8. Maintain a dependency manifest recording reviewed versions, source commits, hashes, and review dates.
  9. Avoid granting downloaded setup Skills access to wallet secrets, private keys, mnemonics, payment headers, or unrelated account data.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
86% confidence
Finding

The description's broad 'Use when an agent needs...' phrasing lacks tight boundaries and may encourage invocation on ordinary education-statistics questions that do not require this specific remote service. In context, this matters because the skill enables outbound MCP/REST tool calls, so overbroad routing can expose user queries to third-party infrastructure unnecessarily.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
85% confidence
Finding

The activation keywords are broad enough to match generic education-analysis requests, which can cause the agent to invoke this external tool in situations where it was not specifically intended. That increases the chance of unnecessary external data transmission and tool overuse, especially because the skill routes queries to remote AgentPMT-hosted calls.

npx commands without a version suffix (e.g. @1.0.0) create a rug-pull risk if the upstream server is compromised and publishes a malicious update.
