The Agent Skills Directory

The skill empower-sync is a descriptive markdown file outlining a git workflow. It does not contain any embedded scripts or executable code. The instructions guide the agent to perform a series of standard git commands such as git status, git fetch, git checkout, git pull, git branch, git show, and git cherry-pick.

Threat Category Analysis:

Prompt Injection: No direct prompt injection attempts were found. The language is instructional and does not try to override the agent's core directives.
Data Exfiltration: No commands or patterns indicative of data exfiltration were detected. The git commands are used for repository operations and do not send sensitive local files to external, untrusted domains.
Obfuscation: No obfuscation techniques (Base64, zero-width characters, homoglyphs, URL/hex/HTML encoding) were found in the skill's content.
Unverifiable Dependencies: The skill relies on the git command-line tool, which is a standard system utility and not an external, unverifiable third-party package in the context of npm or pip. No other external dependencies are introduced.
Privilege Escalation: No sudo, doas, chmod +x, chmod 777, or other privilege escalation commands were found. The git operations are confined to the user's repository.
Persistence Mechanisms: No attempts to establish persistence (e.g., modifying shell profiles, creating cron jobs, or systemd services) were detected.
Metadata Poisoning: The skill's name and description are benign and accurately reflect its purpose. No malicious instructions were found in the metadata.
Indirect Prompt Injection: As with any skill that processes external user-provided input (like a commit SHA) or external content (like a git diff), there's an inherent, low-level risk of indirect prompt injection if the external content itself contains malicious instructions. However, the skill explicitly includes "Safety Rules" such as "Ask for approval to apply" after reviewing the diff (git show <sha> -p), which provides a crucial human-in-the-loop safeguard against such risks.
Time-Delayed / Conditional Attacks: No conditional logic for time-delayed or environment-specific attacks was found.

Conclusion: The skill is a set of instructions for performing a well-defined git workflow. It explicitly includes safety checks and user confirmation steps, which are good practices. It does not contain any executable code, external dependencies beyond the standard git CLI, or malicious patterns. The inherent risk of indirect prompt injection from external content is mitigated by the required user approval step.
