Security checks for vulnerabilities and agentic risk

Overview

The skill coherently converts local construction-cost files into spreadsheets, with a bounded risk of overwriting or mixing previous extraction results.

Use a fresh extraction and output directory for each project and keep original files backed up. Reconcile exported totals and verify version labels before relying on comparisons: the exporters assign submitted/reviewed labels from directory numbers despite the documentation warning against that assumption.

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

Findings (2)

Skill declares no tool scope ('permissions' or 'allowed-tools') but code capabilities were detected: env, file_read, file_write.

Medium

Category: MCP Least Privilege
Confidence: 70% confidence
Finding: Without declared permissions the skill's intent is opaque and cannot be validated.
Content: No source excerpt is available for this finding.

The extraction command silently overwrites existing files without warning the user.

Medium

Category: Output Handling
Confidence: 98% confidence
Finding: The extraction command uses unzip -o with a fixed, reusable ./tmp_sgcfx directory, allowing archive entries to replace existing same-named files without confirmation. Repeated processing can destroy prior extracted data and leave a mixture of old and new files, potentially contaminating financial exports or version comparisons; the local destination limits the demonstrated overwrite scope.
