Geepers Corpus

Security checks for vulnerabilities and agentic risk

Overview

This skill is a simple corpus lookup helper that clearly uses an external linguistics API and does not install code, persist itself, or request broad local access.

Install only if you are comfortable sending searched words and query parameters, plus the configured API key, to the documented external corpus API. Avoid using it for sensitive private text unless you trust that service's handling of requests.

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

External Transmission

Medium

Category: Data Exfiltration
Content: ### Word Search / Concordance ``` GET https://api.dr.eamer.dev/v1/corpus/search?word=serendipity&limit=20 ``` Returns KWIC (keyword-in-context) examples showing the word in actual usage.
Confidence: 50% confidence
Finding: Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.
