Grant Budget Justification

Security checks for vulnerabilities and agentic risk

Overview

This skill is a simple local grant budget justification generator with disclosed file output and no evidence of network access, persistence, credential access, or hidden behavior.

Before installing, understand that this is a draft-quality local script. Use it only with grant budget data you are comfortable processing locally, choose output paths carefully, and expect limited functionality because the documented JSON/CSV input options are not actually implemented in the bundled script.

A.I.G

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

Finding
The skill describes file output capability (`--output`, writing files to the workspace) and explicitly notes local script execution, but it does not declare any tool scope such as `permissions` or `allowed-tools`. This creates an authorization gap where the skill's actual file-write behavior is not constrained or transparently declared, increasing the risk of unintended or overly broad file modification if the implementation is permissive.
