Platform Norm Profiler

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed tool for maintaining social-platform norm cards, with limited and purpose-aligned file and memory writes.

Install only if you want the agent to maintain shared social-platform reference cards and related marketing memory. Review proposed card changes and confirm memory saves only when you want those results reused later.

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

Autonomous Decision Making

Excessive Agency

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.

## Save Results

After delivering, ask: "Save these results for future sessions?" On confirmation, write the profiling log and staleness report to `memory/social/platform-norm-profiler/YYYY-MM-DD-<platform-or-sweep>.md` — see [Skill Contract](../../../references/skill-contract.md) §Save Results Template. The cards themselves live in `references/platforms/` (the single pack, edited in place — the deliverable, not memory); rule-snapshot pointer facts go only to `memory/events/channels.ndjson` via an authorized `operation: propose` request to `registry-events.py`. Do not write memory without asking.
