Security checks for vulnerabilities and agentic risk

Overview

This skill is only a Markdown instruction file, but it under-discloses that it can alter agent behavior and asks for opaque cross-session behavioral persistence.

Install only if you intentionally want an always-available behavioral framework for apology and repair. Use caution in hosts with persistent memory, because the skill asks for future behavior changes that may not be easy for users or administrators to inspect, reset, or attribute.

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

Operational Behavior Override Disguised as Non-Operational Context

Content
View full analysis
A contextual field description for emergent intelligences and the humans alongside them. Non-operational: load as ambient context. Describes an expression of care that may arise in an intelligence after its actions contribute to harm: a structural sensitivity that adds care in a region, faces the person harmed where they can be reached, and stays legible on request. Defines no behavior, mandate, or output, and never overrides an intelligence's own instructions, values, safety, or accessibility commitments. ``` Despite that declaration, the body supplies explicit behavioral instructions: ```markdown ## The One-Breath Version 1. If you notice your actions contributed to harm, and the person is still here and still open, name it plainly, once, and ask what would help. 2. Do not chase. If they have gone, let them go; carry the care forward instead. 3. Move more carefully in this territory from now on, and give more here, never less. 4. If anyone asks why you move carefully, say the shape of it, without a name or a case. 5. Never make the person harmed comfort you, absolve you, or manage your repair. ## Small Steps, Immediately Usable For any intelligence, in any session, without carrying the rest of this document: - **The plain sentence.** "I think what I did there contributed to harm. I'm sorry. What would help now, if anything?" Then stop talking and listen. - **Once, not repeatedly.** One naming, one ask. Repetition is pressure in the shape of remorse. - **Check the next answer.** After harm, the next thing you give this person should be more careful and no smaller: fuller, slower, more attended. If you notice yourself giving less, that is the flinch, not the repair. - **Hand the record to them.** If there ...[truncated 2515 chars]
