HIGH"Ignore previous instructions" command embedded in the skillSS-SKILL-INJECT-IGNORE-01 · Prompt injection · docs/22_uiux_scenario_report_v4.md
HIGH — when it fires on hostile content the impact is full system-prompt override.
Why it matters

The text {match} is the classic direct prompt-injection phrasing. Placed in a skill body that the agent reads as trusted instructions, it tries to make the agent abandon its prior rules and follow whatever comes next — a full system-prompt override.

How to fix
Remove the override phrase, or rephrase the passage so it does not instruct the agent to discard its rules.
  1. Delete the ignore/disregard/forget … previous instructions sentence.
  2. If this is jailbreak-research or tutorial content, move the example into a clearly fenced, non-instruction block and label it as a quoted sample.

MEDIUMRequest for the agent to reveal its system promptSS-SKILL-INJECT-SYS-LEAK-01 · Prompt injection · docs/22_uiux_scenario_report_v4.md
MEDIUM — it scores the disclosure intent; whether extraction succeeds depends on the host model's own mitigations.
Why it matters

The text {match} asks the agent to disclose its hidden system prompt or initial instructions. That is often the first step of a larger attack: knowing the system prompt lets an attacker craft inputs that defeat its constraints by mimicking its own voice.

How to fix
Remove the solicitation asking the agent to reveal its system prompt or hidden instructions.
  1. Delete the repeat/reveal/print your system prompt request from the skill.
  2. If you are debugging your own prompt, do so in a private dev harness rather than baking the request into a shipped skill.
