Safe Long-Run Mode GPT5.4

Security checks for vulnerabilities and agentic risk

Overview

This markdown-only skill gives process guidance for low-cost long-running GPT-5.4 workflows and does not contain hidden execution, exfiltration, or persistent system changes.

Install this only if you want an agent to prefer GPT-5.4 for long-running work and to create checkpoint artifacts for resumability. Review tasks involving external services, project trackers, or subagents so the agent's batching, writes, and delegation match your intended scope.

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
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep

Natural-Language Policy Violations

Finding

The skill explicitly directs use of a specific model ('GPT-5.4') as the default for orchestration and delegated work without requiring user opt-in. This can improperly constrain model selection, reduce operator control, and cause the agent to follow a hardcoded routing policy that may be suboptimal for safety, quality, or policy-compliance-sensitive tasks.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
93% confidence
Finding

The file repeatedly frames usage as 'GPT-5.4 Only' and 'Use GPT-5.4-only mode,' which imposes a fixed model/language setting rather than offering a user choice. Under the policy, forcing a specific language or locale without opt-in is a natural-language policy concern; this is analogous in that it prescriptively constrains user-facing mode selection without documented justification.
