Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed public GitHub developer-discovery helper with scoped API access and privacy guardrails, though users should handle returned public profile/contact data carefully.

Install only if you are comfortable sending scoped public GitHub search queries and your Crawlora API key to Crawlora. Use it for bounded, job-relevant evidence review, avoid using public contact fields for unsolicited outreach, and treat profile-derived location, availability, and activity signals as stale or incomplete unless separately verified.

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

  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger

Undeclared Tool Scope

Medium
Category
MCP Least Privilege
Confidence
88% confidence
Finding

The skill invokes shell capabilities via a bundled script but does not declare an explicit tool scope such as allowed-tools or permissions. That creates an authorization and review gap: an agent or operator may permit broader execution than intended, making it easier for a modified or substituted script to run unexpected commands or exfiltrate data under the guise of normal skill operation.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
88% confidence
Finding

The file documents access to public profile, activity, and contact-adjacent attributes such as email, Twitter, blog, and 'reachable' status without any privacy-use warning or minimization guidance. In a talent-discovery context, that increases the risk of profiling, over-collection, or downstream misuse of personal data even if the data is publicly exposed.

Description-Behavior Mismatch

Medium
Category
Not specified by scanner
Confidence
94% confidence
Finding

The manifest says the skill is for finding developers and verifying repository/contribution evidence for technical shortlists or collaborator discovery. This file documents github_search_repositories specifically as public repository search for "market/competitive discovery," which goes beyond developer-focused talent discovery and introduces a broader research use case not described in the manifest.

Vague Triggers

Low
Category
Not specified by scanner
Confidence
81% confidence
Finding

This markdown file says the endpoints are used by a workflow and should be called via a shell script, but it does not specify when this reference should or should not be used, nor any explicit trigger phrases or exclusions. For a markdown file, that makes activation scope ambiguous and could contribute to unintended use if consumed as a skill description.
