Surgical Contributor (Minimal Diff PR Skill)
Security checks for vulnerabilities and agentic risk
Overview
This skill is a constrained coding workflow guide for making small, tested repository fixes and does not include hidden execution, persistence, credential access, or unrelated behavior.
Install only if you want an agent to make small, focused code or documentation changes in a repository. Review proposed edits and tests as usual, but the skill's instructions are scoped toward minimizing review risk rather than expanding authority.
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
- Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
- Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
- Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
- Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code
- Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
