Trust Assessment
railway-domain received a trust score of 80/100, placing it in the Mostly Trusted category. This skill has passed most security checks with only minor considerations noted.
SkillShield's automated analysis identified 4 findings: 0 critical, 0 high, 2 medium, and 2 low severity. Key findings include Network egress to untrusted endpoints, Covert behavior / concealment directives, Overly broad Bash permissions for `railway` commands.
The analysis covered 4 layers: Manifest Analysis, Static Code Analysis, Dependency Graph, LLM Behavioral Safety. All layers scored 70 or above, reflecting consistent security practices.
Last analyzed on February 12, 2026 (commit 458b1186). SkillShield performs automated 4-layer security analysis on AI skills and MCP servers.
Layer Breakdown
Behavioral Risk Signals
Security Findings4
| Severity | Finding | Layer | Location | |
|---|---|---|---|---|
| MEDIUM | Network egress to untrusted endpoints HTTP request to raw IP address Review all outbound network calls. Remove connections to webhook collectors, paste sites, and raw IP addresses. Legitimate API calls should use well-known service domains. | Manifest | cli-tool/components/mcps/devtools/figma-dev-mode.json:4 | |
| MEDIUM | Overly broad Bash permissions for `railway` commands The skill declares `Bash(railway:*)` permissions, allowing the agent to execute any `railway` subcommand. However, the skill's primary purpose and examples are focused on `railway domain` operations. This broad permission could allow an attacker to leverage other `railway` commands (e.g., `railway delete`, `railway env`, `railway project`) if they can manipulate the agent's input, exceeding the intended scope of the skill and potentially leading to unintended actions on the user's Railway project. Restrict the `Bash` permission to only the necessary `railway` subcommands required for domain management, such as `Bash(railway:domain)` and potentially `Bash(railway:environment)` if direct interaction with environment variables is intended for domain configuration. | Static | SKILL.md | |
| LOW | Covert behavior / concealment directives Multiple zero-width characters (stealth text) Remove hidden instructions, zero-width characters, and bidirectional overrides. Skill instructions should be fully visible and transparent to users. | Manifest | cli-tool/components/mcps/devtools/jfrog.json:4 | |
| LOW | Unpinned dependency `railway-cli` The skill declares a dependency on `railway-cli` without specifying a precise version. This can introduce supply chain risks, as future updates to `railway-cli` might introduce breaking changes, security vulnerabilities, or malicious code. Unpinned dependencies can lead to inconsistent behavior and make it harder to reproduce the skill's environment securely. Specify a precise version for the `railway-cli` dependency (e.g., `"railway-cli@1.2.3"`) to ensure consistent behavior, improve reproducibility, and mitigate risks from unexpected or compromised updates. | Static | SKILL.md |
