Security checks for vulnerabilities and agentic risk
Overview
This local manager mostly matches its stated purpose, but its chat-log writer can be redirected outside the advertised data folder by pod metadata or symlinks.
Review before installing if you will run this in directories where pod JSON files or s2_matrix_data entries could be created by other users, agents, or untrusted tools. Avoid putting sensitive chat content into it unless you are comfortable with local plaintext logs, and prefer a fixed version that validates pod IDs and blocks symlink or path traversal writes.
Vulnerability Patterns
- Insecure Skill Coding PracticesFinds exploitable flaws such as hardcoded secrets or command injection
- 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

Natural-Language Policy Violations
Medium
- Category
- Not specified by scanner
- Confidence
- 97% confidence
- Finding
Nearly all natural-language strings, prompts, and status messages are presented in Chinese, and the skill does not provide any language selection or opt-in mechanism. This can violate language or locale policy when a skill imposes a specific language on users without choice or documented regional justification.

Missing User Warnings
Medium
- Category
- Not specified by scanner
- Confidence
- 94% confidence
- Finding
The skill persistently appends user-entered chat content and derived metadata to local log files without clearly informing the user beforehand or obtaining consent. This can expose sensitive user input, pod identifiers, names, and timestamps to other local users or later processes, especially because files are stored in a predictable location under the current working directory.
