Security audit

Sv Storyboard Planner

Security checks for vulnerabilities and agentic risk

Overview

This is a document-only storyboard planning skill with no code, network access, credential handling, or persistence.

Review the broad trigger words if you install many creative-planning skills, since this one may activate for general storyboard or pre-production requests. No security-sensitive behavior was found.

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

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The trigger keywords are generic terms such as 'storyboard', 'shot list', and 'visual plan' without clear activation boundaries, exclusions, or disambiguation rules. This can cause the skill to activate in unrelated contexts, increasing the chance of accidental invocation, response hijacking, or interference with other skills handling broader creative or planning tasks.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The trigger list includes generic phrases like "storyboard," "visual plan," and especially "pre-production," which can appear in ordinary discussion outside the intended narrow skill invocation context. The file does not provide constraints, exclusion conditions, or negative examples to clarify when these terms should and should not activate the skill.

Natural-Language Policy Violations

Medium
Category

Confidence
92% confidence
Finding

The manifest sets the skill language to "en" with no indication that users may opt into other languages or that English-only behavior is required for a documented reason. This can conflict with language/locale policy expectations when no user choice or justification is provided.

Natural-Language Policy Violations

Confidence
91% confidence
Finding

The checklist explicitly states 'English-first documentation,' which imposes a language preference in natural language. Under the policy rules, forcing a specific language without user opt-in or a clearly justified regional constraint is a violation.

Finding

This manifest lists generic activation phrases such as "storyboard," "visual plan," and "pre-production" without clarifying context, constraints, or negative examples. Those terms can plausibly appear in ordinary creative discussions, increasing the chance of unintended invocation.
