Security audit

FDE Playbook Productizer

Security checks for vulnerabilities and agentic risk

Overview

This is a documentation-only skill for turning validated delivery lessons into reusable playbooks, with clear limits around evidence, authorization, and customer data.

Install only if you intend to process validated delivery evidence into reusable internal assets. Keep customer data de-identified, obtain customer or internal approval before public case studies, and treat single-customer learnings as candidate observations unless the evidence threshold is met.

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
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • YARA SignaturesMalware Match, Webshell Match, Cryptominer Match

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
88% confidence
Finding

The default prompt uses a broad invocation phrase without clear trigger constraints or required preconditions, which can cause the skill to be invoked in contexts beyond validated post-POC productization work. That increases the chance of accidental misuse, inappropriate application to unvalidated customer input, or prompt-trigger collisions with unrelated workflows.

| Five Forces | Assessment Questions |
|------|---------|
| **Competitors** | How fierce is the competition? What is the size and strength of the opponent? |
| **Supplier Bargaining Power** | How much say do suppliers have? |
| **Buyer's Bargaining Power** | How much power do customers have to lower prices? |
| **Threat of Substitutes** | What alternative solutions exist? |
| **Threat of New Entrants** | Is it easy for new competitors to enter? |

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
86% confidence
Finding

This markdown file discusses skill assets and catalogs, and L073 lists a 'Trigger' field but provides no guidance on how specific trigger phrases must be or how to avoid broad everyday-language activation. In the context of skill design documentation, that omission can encourage ambiguous invocation patterns and unintended activation.

Autonomous Decision Making

Medium
Category
Excessive Agency
Confidence
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.

Can the new FDE, without asking the original author:

Scope Creep

Low
Category
Excessive Agency
Confidence
70% confidence
Finding

Skill's behavior or capabilities extend beyond its stated purpose. Scope creep allows an agent to perform actions unrelated to its documented functionality, increasing the attack surface.
