Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed FLUX image-generation guide with expected API use and strong human-review, licensing, and provenance safeguards.

Before installing, confirm you are comfortable with a skill that may use connected image-generation APIs and reference images for FLUX workflows. Verify current licensing and provider terms before commercial use, keep human review before publishing, and do not use it with unconsented likenesses or sensitive reference images unless the chosen provider is approved for that data.

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

Autonomous Decision Making

Excessive Agency

75% confidence
Finding

Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.

"Honest decision tree: easiest commercial path = the hosted APIs (BFL API / fal / Replicate / Together — pay-per-image, license included, provenance metadata applied); self-host free-and-commercial = FLUX.2 [klein] 4B (Apache 2.0, ~13GB VRAM, sub-second); [dev] weights = non-commercial license for self-hosted commercial services (paid license tiers exist)",
        "Matches variant to job: [pro]/[flex] for production quality, [klein] for speed/local, [dev] for research/tinkering, [max] when web-grounded content matters",
        "Flags that license terms shift — verify at bfl.ai/licensing (verify-quarterly)",
        "Never claims a variant is free-for-commercial without checking its actual license"
