Consent Registry

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed consent-record registry that uses scoped, pseudonymous records and does not show hidden or unrelated behavior.

Install only where you intend the agent to maintain a consent/suppression registry. Confirm the referenced host runtime and registry script are trusted, and treat suppress/erase operations as persistent business records even though they are scoped and privacy-oriented.

A.I.G

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

Finding

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

**Unit:** one pseudonymous subject ID supplied by the user's system. **Reads:** `memory/events/consent.ndjson` by replay, its projection, and minimum proof references. **Writes:** consent events only through `registry-events.py`; human records are projections. **Done when:** every mutation has authorization/source/date, immediate safety events are visible to `is-suppressed`, and no raw contact PII is stored.

Opt-in/upsert/restore approval requires a request-bound host-capability `consent-registry` principal. `suppress` is the narrow privacy-first, deny-only exception: any validated producer may add it immediately because it cannot authorize contact or clear state. `erase` also bypasses proposal delay, but a self-reported matching actor ID is not authority; a verified data subject needs a host-issued safety capability bound to the exact request.

Finding

This manifest contains packaging metadata only and does not provide any invocation phrases, activation scope, or exclusion conditions. For manifest files, absence of trigger specificity can make it unclear how narrowly the skill is intended to activate, which fits the vague-trigger category.
