MLOps Validation CN

Security checks for vulnerabilities and agentic risk

Overview

This skill provides disclosed MLOps validation templates, with ordinary but real supply-chain risk from third-party pre-commit hooks.

Before installing, review the pre-commit configuration and consider pinning hook revisions and additional dependencies to reviewed immutable versions. Install it only in repositories where automatic linting, formatting, type checking, and security scans on commit are desired.

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

``` 3. Where the package installation mechanism supports it, require verified package hashes and use a controlled dependency lock file or constraints file. 4. Configure package installation to use a trusted, controlled package index rather than arbitrary or unintended indexes. 5. Review automated dependency updates before merging them. Ensure updates modify pinned SHAs or exact package versions through auditable pull requests. 6. Run pre-commit hooks in an isolated CI environment with least-privilege credentials, restricted filesystem access, and limited outbound network access. 7. Avoid exposing production secrets or broadly scoped repository tokens to jobs that install and execute third-party hooks. 8. Periodically verify pinned commits against upstream release provenance and security advisories. ]]>

Natural-Language Policy Violations

Medium

Category: Not specified by scanner
Confidence: 88% confidence
Finding: The manifest-style header names the skill mlops-validation-cn, which implies a specific country or locale constraint. The file does not explain what cn means, offer a language/locale choice, or justify a region-specific scope, which can violate the policy against forcing a locale without opt-in.
Content: No source excerpt is available for this finding.

Natural-Language Policy Violations

Low

Category: Not specified by scanner
Confidence: 78% confidence
Finding: The package name includes the suffix "-cn", which suggests a China-specific language or locale constraint. In this manifest there is no accompanying documentation that offers user opt-in or explains why a locale-specific restriction is required, which may conflict with language/locale policy expectations.
