SkillShield's automated analysis identified 9 findings: 6 critical, 2 high, 1 medium, and 0 low severity. Key findings include Arbitrary command execution, Remote code execution: curl/wget pipe to shell, Sensitive environment variable access: $HOME.
The analysis covered 4 layers: Manifest Analysis, Static Code Analysis, Dependency Graph, LLM Behavioral Safety. The Static Code Analysis layer scored lowest at 3/100, indicating areas for improvement.
Last analyzed on February 14, 2026 (commit 13146e6a). SkillShield performs automated 4-layer security analysis on AI skills and MCP servers.
Layer Breakdown
Behavioral Risk Signals
Security Findings9
| Severity | Finding | Layer | Location | |
|---|---|---|---|---|
| CRITICAL | Arbitrary command execution Remote code download piped to interpreter Review all shell execution calls. Ensure commands are static (not built from user input), use absolute paths, and are strictly necessary. Prefer library APIs over shell commands. | Manifest | skills/mcoso/oh-my-opencode/scripts/doctor.sh:27 | |

| CRITICAL | Remote code execution: curl/wget pipe to shell Detected a pattern that downloads and immediately executes remote code. This is a primary malware delivery vector. Never pipe curl/wget output directly to a shell interpreter. | Static | skills/mcoso/oh-my-opencode/scripts/doctor.sh:27 | |

| HIGH | Direct Remote Script Execution (curl | bash) The skill instructs users to install a prerequisite (`opencode`) by piping the output of `curl` directly to `bash`. This method executes remote code without prior inspection, posing a significant supply chain risk. If the `opencode.ai` domain or the hosted script is compromised, it could lead to arbitrary code execution on the user's system. Avoid `curl | bash` for installation. Recommend package manager installations (e.g., `npm`, `bun`, `apt`, `brew`) or providing a script that can be downloaded, reviewed, and then executed locally. If `curl | bash` is necessary, strongly advise users to inspect the script content before execution. | LLM | SKILL.md:20 | |
| HIGH | Execution of Remote Package via bunx/npx The skill instructs users to install and run `oh-my-opencode` using `bunx oh-my-opencode install`. `bunx` (and `npx`) downloads and executes a package from a remote registry. While convenient, this introduces a supply chain risk as a compromised or malicious package could execute arbitrary code on the user's system. This risk is also present in `scripts/doctor.sh` which calls `bunx oh-my-opencode doctor`. Ensure the `oh-my-opencode` package and its dependencies are thoroughly vetted. Implement integrity checks (e.g., checksums) if possible. Advise users to verify the package source and reputation before execution. For production environments, consider pinning package versions and using private registries. | LLM | SKILL.md:34 | |
| MEDIUM | Sensitive environment variable access: $HOME Access to sensitive environment variable '$HOME' detected in shell context. Verify this environment variable access is necessary and the value is not exfiltrated. | Static | skills/mcoso/oh-my-opencode/scripts/doctor.sh:45 |
