git-commit-skill

Security checks for vulnerabilities and agentic risk

Overview

This skill is a transparent Git commit assistant that reads repository changes, checks for likely secrets, and only stages, commits, or pushes after user confirmation.

Install this if you are comfortable letting the agent inspect your current Git diffs and run user-confirmed git add, commit, and optional push commands. Review the generated commit message and staged files carefully, especially when secrets or environment files appear in the changes.

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

Credential Access

High
Category
Privilege Escalation
Confidence
70% confidence
Finding

Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The skill's natural-language instructions, prompts, and examples are all in Chinese, which effectively forces a specific language for users. The file does not provide opt-in, alternative language support, or a documented reason that the skill is intended only for a Chinese-speaking or region-specific context.

Content

No source excerpt is available for this finding.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
91% confidence
Finding

This reference file is written entirely in Chinese, beginning with the title on L001, and does not indicate that language selection is optional or that the skill is intentionally limited to a Chinese-speaking audience. Under the policy rule for natural-language violations, forcing a specific language without user opt-in can be a locale-policy issue.
