FDE PRD Writer

Security checks for vulnerabilities and agentic risk

Overview

This skill is a focused PRD-writing aid with a local traceability checker and no hidden network, persistence, or privilege behavior.

Install this if you want a structured PRD handoff workflow. It may read the upstream materials and PRD files you provide, and the optional checker runs locally on a file path you choose; review generated requirements before sharing them with engineering or customers.

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
  • Memory PoisoningPersistent Context Injection, Context Window Stuffing, Memory Manipulation
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access

Memory Manipulation

High
Category
Memory Poisoning
Confidence
85% confidence
Finding

Skill manipulates agent memory, state, or stored context. Memory corruption can alter personality, override safety rules, or cause unpredictable behavior.

### Mermaid: Reduce misunderstandings of complex processes

Prioritize drawing state changes, responsibility boundaries, conditional branches and asynchronous callbacks. Diagrams do not replace rules, permissions, or acceptance criteria; each item must still map to `FR-`and`AC-`.

### JTBD / 5W1H: Avoid treating solutions as requirements

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.

Confidence

Finding

The CLI emits status lines using full-width separators and labels such as '|', 'Block|', and 'Reminder|', which impose a locale-specific presentation format on all users. The file does not offer a language/locale choice or explain that the tool is intended for a specific regional context.
