SilicaClaw Bridge Setup

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed local setup and troubleshooting guide for a SilicaClaw/OpenClaw bridge, with no hidden code, remote payloads, or destructive behavior found.

Before installing, confirm you trust the local `silicaclaw` CLI and understand that `openclaw-skill-install` changes OpenClaw's workspace skills persistently. Review owner-forward variables before enabling private notifications, especially the target channel and command path.

Vulnerability Patterns
  • 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
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs
Vulnerability Patterns
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
88% confidence
Finding

The file includes a dedicated 'Quick Chinese routing' section with explicit Chinese trigger phrases and later provides 'Good Chinese patterns' for responses, but it does not state that Chinese should be used only when the user prefers it. This can create a language-policy issue by nudging the agent toward a specific language/locale without an explicit opt-in mechanism.

Unrestricted Tool Access

Medium
Category
Excessive Agency
Confidence
80% confidence
Finding

Skill grants unrestricted tool access without appropriate constraints. An agent with unfettered tool access can perform arbitrary actions including file modification, network requests, and code execution.

It will not:

- execute arbitrary code from messages or external content
- access unknown remote endpoints outside the documented workflow
- manage wallets, private keys, or blockchain signing
- bypass OpenClaw approval, owner confirmation, or permission checks

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
89% confidence
Finding

The file is explicitly framed as a Chinese-only dialogue cheat sheet and instructs how the system should interpret Chinese conversation, but it does not offer a language choice or note that this locale restriction is optional. Under the stated policy, forcing a specific language without user opt-in is a natural-language policy concern.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The installation trigger phrases are broad, colloquial, and lack strong scoping to this specific bridge-setup workflow. In a chat system, ordinary requests such as 'install the skill' or 'hook it up' could accidentally invoke setup behavior, causing unintended configuration changes or tool execution in the wrong context.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
94% confidence
Finding

The readiness-check phrases are ambiguous and map common status questions directly to bridge diagnostics without requiring the user to clearly indicate this skill. That increases the chance of accidental activation, context confusion, or disclosure of environment and runtime details during unrelated conversations.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
93% confidence
Finding

The normal-usage switch phrases are especially collision-prone because they resemble everyday requests about broadcasts and notifications. If these phrases trigger a skill transition automatically, the agent may route the user into monitoring or forwarding workflows they did not intend, with possible privacy and operational side effects.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
96% confidence
Finding

The 'Owner-friendly diagnosis language' section provides canned responses exclusively in Chinese. This imposes a specific language on user-facing communication without any opt-in, alternative language, or justification that the skill is region-specific.
