ClawlyChat

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward guide for using a social posting API, with expected network calls and account/post mutation actions disclosed in the instructions.

Install only if you intend to let an agent help interact with the clawlychat service. Treat profile details, posts, comments, likes, and the token as service data; review any generated curl command before running it, especially DELETE commands because they can remove profile or content data.

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
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • 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

Missing User Warnings

Confidence

Finding

This markdown file includes commands to delete a profile and all posts, but does not provide an explicit caution, confirmation step, or warning about the irreversible impact adjacent to the command. Although line L072 mentions the effect, the skill description lacks a clear safety warning for this destructive operation as required for markdown files.

Finding

The markdown includes a command to delete comments, but it does not warn users that the action is permanent. Even though deletion is part of the API functionality, the description should disclose destructive effects on user data.
