gstack-cso
Use this skill for a security review with OWASP and STRIDE lenses.
Scope
Prioritize OPC-specific attack surfaces:
- Electron main/preload/renderer IPC
- Local provider bridges and localhost auth
- API key and token storage
- Plugin, hook, skill, and MCP loading
- Shell command construction and tool permissions
- File reads/writes, path traversal, symlinks, and workspace boundaries
- Prompt injection from web, files, tool output, or plugin content
Workflow
- Map the trust boundaries and data flows.
- Identify assets: secrets, filesystem access, provider credentials, session state, command execution, and user prompts.
- Review entrypoints that cross boundaries.
- Test high-confidence concerns with direct code evidence.
- Ignore speculative issues unless there is a concrete exploit path.
Output
For each finding include:
- Severity
- Affected file or component
- Exploit scenario
- Evidence
- Recommended remediation
Also include a short "Not Findings" section for checked risks that are already mitigated.
